[android-developers] Re: ADT r15 reliabiility on Windows?
Every time you update software, there is more than a good chance that it probably didn't clean up after itself and has left old and/or orphaned files and entries. Not to mention the settings in different layers of software that you may know nothing about. There is a good chance Eclipse, ADT and Java keeps all the old settings around update after update. Then you have overall project settings and then specific project settings. The odds of one of those five having a rogue setting that could cause issues is pretty good. The longer you go without cleaning house, the more likely you are to end up with internal problems. That's not even mentioning the fact that each component of Eclipse, and any other plugin you have in Eclipse, also has settings. Just look in your Workspace .metadata directory. Each plugin can carry its own settings in those folders. There are probably hundreds, if not thousands, of settings that can affect how well your environment behaves.

[android-developers] Re: Google+ App consumes phone memory
The application and the data that the application stores/caches are two different things. If you move the application to the SD card, it does move and frees up most of whatever memory the application itself was taking up. The data that the application produces may still use the internal memory as the preferred location. If so, than it will continue to take up internal memory like you are seeing. You may want to check the settings for it, and other applications, to see if you can set them to use another storage location for files/cache so they won't fill up your internal memory.

Re: [android-developers] How to get updated c2dm registration Id.
That should be a correct response. You may want to refresh your C2DM key on the device and then refresh the server with the updated one. You may want to call the unregister intent on device first with the following: http://code.google.com/android/c2dm/index.html#unregistering I would figure that unregistering a device would remove all previous entries if there is more than one entry. I'm not sure that there can be more than one ID for a device for the same app, but it is worth trying the unregister intent to see if it might help clear up your issue.

Re: [android-developers] How do you use and debug your apps in your main phone?
You can always change the package name to add beta or something in it somewhere. The same application can live on your device twice if the package names aren't the same. I've done it before and as long as you are using storage that is specific to the app instead of a common directory on the SD card, you should be fine. You can run into issues if they try to control the same hardware, but it is an option you can work with. Just name the working version com.yourcompany.app and the beta com.yourcompany.app.beta and you can use them both. Once you get a solid working copy in beta, you can just copy and/or rename the package and overwrite your standard version with it and keep working on the beta. It's certainly not the most elegant solution, but it does work. I've used it for testing new features or different feature sets while still keeping the original around to compare.

[android-developers] Re: Newb Learning to Debug
Check out the log functions here: http://developer.android.com/reference/android/util/Log.html You drop them in and around the functions you want to debug to output variables and status. Doing this helps you confirm in real-time that things are going well. There are times where you will not be able to debug the standard way and these will help a ton. To use them, just pick which category you want the message to show up in LogCat and use that Log.x function. Put them before functions to validate you are sending in the correct arguments and you'll also know which file/string/object it is working on when it fails. These are also great to put at the start of built-in functions like onCreate, onStart, onResume, etc. to watch the actual flow of your program. You can put them at the start of methods to let it tell you which methods it is calling and when to get a better understanding of how Android works. Add them to your most important functions (or all functions) and you'll have a beautiful picture of how exactly your code gets executed. It's great for optimizing.

[android-developers] Re: Stack overflow error
Put a log output in your onFocusChange and run it again. I think you may find you are causing an infinite loop. Notice in your error log that they are all on the same millisecond and you have multiple onFocusChange hits. Without more code, I can't validate this for sure, but I've seen this before. You have to be careful when using onFocusChange when you are changing the view structure because of the focus change. Changing the view structure can cause additional focus changes, which in turn, can cause an infinite loop. It might be what is happening to you there.

[android-developers] Re: Android fragmentation study
Eh, it's not that bad. If you look at the history of developers, we're already use to having to deal with a lot worse fragmentation issues than Android. Anyone that's ever developed a website correctly knows that supporting the available web browsers is a lot more of a challenge than with Android versions. Windows, Mac OSX, a ton of server technologies, databases, etc., they all have tons of different versions available to support. Most companies stick with older versions because it is what they have and it is working. When it comes to Android, I've been pleasantly surprised at the efforts Google has gone through to help manufacturers upgrade. Even though 2.1, 2.2 and 2.3 are different, they aren't so much different that in most cases you can't treat them as 2.x. It seems to me that Android is more broken up in 1.x, 2.x, 3.x and now 4.x instead of the individual versions themselves. I'd rather a little fragmentation in Android than for them to pull an Apple and everyone is the exact same, right down to the hardware level. Variety is something we need in the mobile market, not a one device fits all concept.

I don't have any battled tested apps using it at the moment, but I have been testing it on some internal applications for a company.

It took about 30-60 minutes from start to finish for both the Android and server side to get working with no previous knowledge of it. I'd recommend you test it out for yourself.

[android-developers] Re: Data values not populating in the gridview on screen orientation using onConfigurationChanged
Regardless of which way you choose to go, configChanges or not, you'll want to cache any response you receive via HTTP. There are a lot of ways to cache these items. You could use static variables, save them temporarily to files on the internal or external (SD Card), add them to a database, etc.. Just remember to use disk storage if you need/want longer term cache copies as static variables are volatile. When the view changes, just pull from the cached copies for the new layout. This could also be valuable for having something to display when a users runs your app again. You can keep the cached copy to display to them while you check for updated resources, then just replace anything that has been updated. This will make sure your users won't just be looking at a blank screen while you retrieve whatever info you need. Caching information is your friend and coming up with a good cache/update scheme that works for your environment will give your users a better overall experience.

Re: [android-developers] Re: Cache issue
The way you cache and access that cache can change depending on how you display the items. If you have that many images, you may want to make thumbnails of them and display those first. This would speed up load times. You could load and hold onto the reference to the full image as the user selected them. Remember you are working in an environment that there will be no way the user can look at all 200 of your full size images at the same time, so plan accordingly. Without knowing what you are trying to accomplish, there's not a lot more we can help you with.

Couple of things here...
1. You are calling run() on the thread, not the one you have defined in
your activity.
2. You don't want to call run() on the thread, you want to call start().
3. You either need to create a Runnable to post to the thread or you need
to extend Thread and insert your own code.
Try this:
private void doLogin()
{
LoginThread ltNew = new LoginThread();
ltNew.start();
}
private class LoginThread extends Thread
{
@Override
public void run()
{
// Your login code here
}
}
That is one option. Give it a try and see if it does what you need it to.

Re: [android-developers] Re: alarm type application: alarm manager not waking up application
Have you considered using a MediaPlayer instead of just a straight Ringtone
object? You can pass the URI of the Ringtone to the MediaPlayer and have
better functionality.
I use the MediaPlayer and create a MediaPlayer.OnCompletionListener to watch
for the end of the playing. This doesn't always fire, so I also use a
postDelayed to make sure I check for the end also. You can use
MediaPlayer.getDuration() and use it to set the time for your postDelayed.
Here are some of the APIs I make use of:
http://developer.android.com/reference/android/media/MediaPlayer.html
http://developer.android.com/reference/android/media/MediaPlayer.OnCompletionListener.html
http://developer.android.com/reference/android/media/MediaPlayer.html#getDuration%28%29
It's worth upgrading to a more full featured audio player if you want better
control.
*Note:* I've experienced times where the audio just stops playing without
posting back a callback like
MediaPlayer.OnCompletionListenerhttp://developer.android.com/reference/android/media/MediaPlayer.OnCompletionListener.html,
MediaPlayer.OnErrorListenerhttp://developer.android.com/reference/android/media/MediaPlayer.OnErrorListener.htmlor
MediaPlayer.OnInfoListenerhttp://developer.android.com/reference/android/media/MediaPlayer.OnInfoListener.html.
Not sure if it was a hardware thing, but I tried everything and there would
be times where I'd not get any notification of it stopping. Because of that
fact, I do recommend the postDelayed with the duration (plus a slight time
padding) of the audio to finish any clean-up after the audio.

[android-developers] Re: Storing database of information?
Have you considered just making the application come without data and then pull the data from a server? It would be much easier on you to not have to republish the application every time you wanted to change some of that data. The basic steps would be something like this: 1. Publish app without data 2. App checks for the last time it got data against the last update on the server 3. Download updated data if needed You could have it check in the background each time the user used the application and notify them that they needed an update or use C2DM for push notifications.

receiver android:name=.services.TestService
intent-filter
action android:name=android.net.conn.CONNECTIVITY_CHANGE/
/intent-filter
/receiver
uses-permission android:name=android.permission.ACCESS_NETWORK_STATE/
See how that works out for you as a test.

[android-developers] Re: about layout sizes
I think when you assign it programmatically it defaults to standard pixels. You would need to get the DisplayMetrics and multiply your pixels by the DisplayMetrics.density to get the same thing as dip/dp in the XML.

Re: [android-developers] Re: Eclipse, ADT and opening XML files
You keep referring to Eclipse 3.7.1 Classic, have you tried Eclipse IDE for Java Developers to see if you get the same results?

Re: [android-developers] Re: alarm type application: alarm manager not waking up application
Not sure this is it, but I noticed on this line of your code: pendingIntent = PendingIntent.getBroadcast(ctx, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); You are sending a 0 as the second argument, try sending something other than 0 there. I've noticed in my own experience that this doesn't like to be zero. Also, try changing the flags to: PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_CANCEL_CURRENT I've used this combination with my RingLock application and it has never failed me. I had issues when sending a 0 as the request code and the flags that don't cancel previous timer events.

However left me give an update on the testing I have carried out. I have reinstalled the app from scratch and set alarms to expire every five minutes (each time an alarm goes off it sets up the next one for the next five minutes). Here is what I have observed: - The first alarm goes off just fine and I see the popup window and hear the sound. - If I keep fiddling with the device the next alarm goes off and I see the popup window and hear the sound so long as I keep fiddling with the device. - As soon as I have not fiddled with the device for five minutes (the screen goes blank after one minute) the alarm goes off and the popup window exists behind the darkness and I hear the sound, but at the next alarm time the popup window is not displayed, and neither the next one nor the next one and so on - Then when I press a hardware button and the screen lights up the next alarm that goes off has the popup window pop up and the sound play. - Again, if I do not touch the phone, the five minute later alarm sounds but not the next one nor the next one. In adb logcat the only suspicious line I can suspect is the following after I try to launch my activity: D/KeyguardViewMediator( 1563): !com.android.internal.policy.impl.KeyguardViewMediator 643! wakeWhenReadyLocked(4) In dumpsys alarm I see all of my 11 wakeups and 11 alarms. % So now I must learn how to keep the CPU running or when the alarm goes off I will not be able to pop up the window and play the sound. When I leave the phone for a while the CPU hybernates or something it seems, so my RTC_WAKEUP calls the broadcast receiver but does not pop up the intent it seems. Can someone please teach me how to use wakelocks and exactly what they are so that I may fix this problem either by keeping the CPU running all the time, or in some more efficient way if possible?

In fact, setting an alarm automatically cancels all alarms that may have been set with the same pending intent. The problem is that in my function sometimes based on what the user does in the user interface I sometimes need to cancel the alarm without setting a new one, so that is why I keep the static pending intent around, otherwise how do I go about cancelling the alarm without setting a new one? As far as the sound goes. Wake-up alarms only hold the wake lock long enough to call onReceive. What kind of wake lock? Because I see there are four kinds and am still struggling to understand what I'm supposed to do with the wake lock. Does your code hold a wake lock while playing the sound? No, only when launching the intent. You could also use a Notification with sound (perhaps as a test), I believe they take care of holding the device awake for themselves. Just make sure to post the notification from onReceive, while the system is holding a wake lock for you. That means I have to learn all about notifications as I have never used them before. So notifications hold the wake lock... I could use a notification and a pop up at the same time??? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Impossible to Create Write to or Read From Files in the SD Card
You're on the right track, but it's best not to hardcode the path to a file
on the SD Card. Check out this API:
http://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory%28%29
This will help you get the directory to the SD card. It usually isn't
/sdcard, it's usually /mnt/sdcard, but it may move or may be renamed on
devices, so it's best to use that or a similar API to help you find it.
Check out these APIs also:
http://developer.android.com/reference/android/os/Environment.html#getDataDirectory%28%29
http://developer.android.com/reference/android/content/Context.html#getDir%28java.lang.String,%20int%29
http://developer.android.com/reference/android/content/Context.html#getExternalFilesDir%28java.lang.String%29
http://developer.android.com/reference/android/content/Context.html#getFilesDir%28%29
There are a lot of functions in the API to help you find a good spot to put
your data files depending on what you are doing. There are even more than
this, but this should get you started.

FileOutputStream fOut = new FileOutputStream(myFile);
OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut);

also tried this one, which works in the Java project but not in

String path = /sdcard/data.txt;
File dosya = new File(path);
dosya.createNewFile();

forget to add uses-permission
android:name=android.permission.WRITE_EXTERNAL_STORAGE/ permission
line into the manifest.
I'm checking the F driver after executing the program to see if any
txt file created, but nothing happened so far. I read SD card is not
available when the android device is hooked up to the computer via USB
in somewhere. To check this possibility, i also looked at the sd
card's context with an laptop sd card adapter but again, i have
nothing.
Please someone help me. I'm out of ideas.

[android-developers] Re: Handling asynchronous events and blocking
I figure you are running a thread that does all the processing as not to block the UI thread. If so, one of the ways I've been doing it is to add something like... public static LinkedListMotionEvent uiEvents; ... to a helper object and then check the length of it every time through the processing loop. You can either call length() on this or you can keep up with the count yourself which might be a bit faster. In whatever view you are catching touches, just insert the MotionEvent into this list. This should leave the UI thread clear and let the processing thread get the touches as time allows. Once I process the first event, I remove the event from the list and continue. I tend to only process one per frame so I don't cause hitching in the movement. If you are running about 30 fps, most people won't be able to touch faster than the ~33ms they have between frames anyways. I use a LinkedList so it keeps the touches in the order I insert them so I don't have to worry about out of order touches. Just one idea, someone else may have a more effective one, but hope that helps.

[android-developers] Re: Facebook SDK error
If you are not wanting to return info to Activity A from Activity B, just
use startActivity() in Activity A instead of startActivityForResult().
If you use startActivityForResult() to launch Activity B from Activity A,
Activity A expects Activity B to send information back when it closes. You'd
use something like this if you wanted to send information back from Activity
B to Activity A after calling startActivityForResult() from Activity A.
Intent iReturn = new Intent();
iReturn.putExtra( someKey, someValue );
setResult( RESULT_OK, iReturn );
finish();
But again, if you aren't wanting a return, use startActivity() to start
Activity B.

[android-developers] Re: obtain rectangle on touch
You'll need to keep up with where you draw the squares, do some simple math
to decide which one was touched and then draw that square a different color.
You might be better served with...
http://developer.android.com/reference/android/graphics/Canvas.html#drawRect%28float,%20float,%20float,%20float,%20android.graphics.Paint%29
...instead of constantly using a Rect if you draw a ton of squares that can
be done with a simple formula like that. When you grab the click, divide the
touch X by the square width and the touch Y by the square height to get the
quadrant the click landed in. Draw that area a different color and there you
go.
If you do decide to use a Rect, would be better to create it outside the
loop and just set the top, left, bottom and right via the fields or use the
offset() and offsetTo() functions. Making a new Rect constantly inside the
loop is super inefficient.

A connection refused error seems like there is just something off on your connection path. Have you confirmed that you are aiming the device at the correct IP and port? Are you testing on a development server inside your own network environment or a production server on the internet? What type of data connection are you using on the device and is there any chance of a firewall or carrier blocking that specific port? It would probably be helpful to get a bit more explanation. It doesn't sound like it is an issue with Android since you aren't showing any crashes. If you don't have the right permissions in Android, you'd get a force close and the error in logcat would tell you which ones you were missing. Any information you can give about the setup would help us help you.

You may want to try layering windows on top of each other to create the effect you are looking for. For example, place a video window under a ImageView window. Once you have that, populate the ImageView with a solid color PNG that has a transparent shape in it. You can use a FrameLayout or RelativeLayout to hold the two views as they allow views to overlap each other easily.

[android-developers] Re: RFID card reader
Unless there is a Bluetooth version, you would probably need to use a tablet (until ICS) and use the USB functionality in API Version 12 and above: If the RFID reader acts as an input device (like a barcode scanner), you can just plug it in and it should work. I've used USB barcode scanners on my Xoom without any problems. You will need a Bluetooth keyboard if you want to be able to put other text in. If it works like the barcode scanner, it will act as the input device (replace the on-screen keyboard), so the on-screen keyboard won't pop up and that's where the Bluetooth keyboard comes into play. If it doesn't act like a standard input device, you will probably have to talk to it directly via the USB API: http://developer.android.com/reference/android/hardware/usb/package-summary.html You would need developer documentation for the RFID, so that may be a problem. If you have the protocols needed to talk to the RFID reader via USB, then you should be able to do it.

Re: [android-developers] Re: android.text.format.DateFormat.format performance
Thanks for the update!
I just sat down and put together a JNI routine that uses strftime in C and I
took my formatting from 50%+ of the routine that was populating my view down
to 0.2%. I would call that a significant improvement! Here is the code I
used:
Java Class
public class JNIUtils
{
private static native String dateFormatJNI( String sFormat, long millis
);
static
{
System.loadLibrary( jniutils );
}
public static String dateFormat( String sFormat, long lTime )
{
return dateFormatJNI( sFormat, lTime );
}
}
C File
#include jni.h
#include time.h
JNIEXPORT jstring JNICALL
Java_com_company_project_jni_JNIUtils_dateFormatJNI( JNIEnv *env, jclass
cls, jstring format, jlong millis )
{
time_t javaTime = millis/1000;
struct tm * timeInfo;
char buffer[32];
const jbyte *str;
str = (*env)-GetStringUTFChars( env, format, NULL );
timeInfo = localtime( javaTime );
strftime( buffer, 32, str, timeInfo );
(*env)-ReleaseStringUTFChars( env, format, str );
return (*env)-NewStringUTF( env, buffer );
}
I am new to JNI, so I'm not sure how clean this code is. I know C/C++, but
I'm getting use to how you have to deal with the Java-to-C layers properly.
Regardless, this runs about 250x (or more) faster than the built-in Java
version.
You may want to check this out if you feel like getting the NDK installed
and configured to where you can build the libraries.

It is slow and so is String.format(). I've been messing around with it a
bit and here is a *rough *sample I tested:
private static final String DATE_AM_PM[] = { am, pm };
private static Date dFormat = new Date();
private static int iHour, iAMPM;
public static String formatDate( long lTimestamp )
{
dFormat.setTime( lTimestamp );
iHour = dFormat.getHours();
if( iHour == 0 ) { iHour = 12; iAMPM = 0; }
if( iHour == 12 ) { iAMPM = 1; }
else if( iHour 0 iHour 11 ) { iAMPM = 0; }
else if( iHour 12 iHour 24 ) { iHour -= 12; iAMPM = 1; }
return dFormat.getMonth() + / + dFormat.getDay() + / +
(dFormat.getYear() + 1900) + + iHour + : + dFormat.getMinutes() +
DATE_AM_PM[ iAMPM ];
}
As I said, it is rough and doesn't even format the output fully.
I tossed this in my application and used it a bit for a speed test and
this takes up half the time as the formatting routines do. Funny thing is,
it has nothing to do with the date part. It seems the formatters are using
a
StringBuffer and some replace functions in the StringBuffer and that is
what
is slowing it down. I may try to work up a JNI replacement and see if some
sprintf or fprintf action fix the issue but it may not because of the extra
layer.

[android-developers] Re: listview adapter. Recycle bitmap
Based on the code there, you wouldn't have the chance to recycle the bitmap
as you don't keep a handle to it anywhere.
Then again, if the ListView discards that particular row and you aren't
retaining any handles to the bitmap, then the bitmap should be scheduled for
collection by the GC. If you did try to retrieve the view that was holding
the image from the ListView and it did return it to you, there is a good
chance the ListView still wants to use it and you would not want to release
the bitmap.
Is there a reason you are wanting to try to recycle the bitmap?
Also, we are talking about the recycle() function on bitmap and not reusing
the same bitmap, correct?

[android-developers] Re: how to connect using HttpClent
Here is the code I use and I have never had any issue out of it.
HttpURLConnection hucConnection = null;
try
{
URL uInfo = new URL( YOUR_URL_HERE );
hucConnection = (HttpURLConnection)uInfo.openConnection();
hucConnection.setRequestMethod( POST );
hucConnection.setRequestProperty( Accept-Encoding, identity );
hucConnection.setDoOutput( true );
String sPost = URLEncoder.encode( key1, UTF-8) + = +
URLEncoder.encode( value1, UTF-8);
sPost += + URLEncoder.encode( key2, UTF-8) + = +
URLEncoder.encode( value1, UTF-8);
sPost += + URLEncoder.encode( key3, UTF-8) + = +
URLEncoder.encode( value1, UTF-8);
OutputStreamWriter out = new OutputStreamWriter(
hucConnection.getOutputStream() );
out.write( sPost );
out.flush();
int iSize = hucConnection.getContentLength();
byte[] bReturn = new byte[ iSize ];
InputStream in = new BufferedInputStream( hucConnection.getInputStream() );
in.read( bReturn, 0, iSize );
String sReturn = new String( bReturn );
Log.i( URL Return, Return: + sReturn );
}
catch( Exception e ) { e.printStackTrace(); }
finally { hucConnection.disconnect(); }
I use the accept-encoding line to disable compression because I don't send
large amounts of data via the connection and it simply (and speeds up)
processing the return. See the note in the following link for more
information.
Depending on what platform version you are aiming for, you may want to check
out the following link:

[android-developers] Re: No longer want meaning when implementing an app widget
A widget on the home screen is just a cached view that is shown there. Since the widget is a BroadcastReceiver with disconnected UI, it only runs when an action happens. Once it deals with the action, and updates a RemoteView object which it sends to the system, it dies. A widget is not actively running and needs a service as a support method if you want to do long operations. To support a widget for long process, you might want to start up a service and do whatever you need to do there. Once you have the new data or whatever you were trying to get, you can send an intent broadcast to tell your widget to update itself.

Re: [android-developers] Re: No longer want meaning when implementing an app widget
True, I just usually have all the display update code in the widget itself, so instead of duplicating it, I just send an update intent to the widget. Either way, to maintain only one set of display update code, you'd either have to have the widget start the service (even when not needed) or have the service issue an update intent to the widget (when needed). If you use the service on every action on the widget, I'd go with what Mr. Murphy said. If you update the display of the widget a decent amount where you don't need to fire off the service, I'd go with the code in the widget.

Re: [android-developers] Re: Multiple Display suport
There are products that have a transmitter/receiver combo that you can send video/audio wirelessly. I don't think there is any reason you wouldn't be able to hook an Android device with an HDMI connector to these units. I don't think there is any built-in code to handle transmitting video/audio that would go out the HDMI to a wireless receiver via the wireless on the phone. You would need the external devices to do that.

[android-developers] Re: Best approach for onConfiguratinChange()
There has been a decent amount of conversation on this subject and there's no right answer. Regardless of which way you pick, make sure you understand the pros and cons. If you let Android do the work for you, make sure you understand that your application can be killed off and restarted at any time just by the user rotating the phone, docking, pulling out a hardware keyboard or game pag, etc.. There are quite a few times this can happen, so it would be best to know when it is going to happen and make sure your application is prepared to deal with it at any time. If you decide to handle the changes yourself with configChanges, you only need to handle the changes that impact your application. If you use the same layout for both portrait and landscape, you don't need to handle rotation changes or hardware keyboard/game pad events. Only catch the ones that will impact your application. Check out the configChanges documentation: http://developer.android.com/guide/topics/manifest/activity-element.html#config Each of the events listed there is a time where Android will stop and restart your application if you let it handle the changes. There may be more that aren't documented there, but those are the major ones. If you decide to handle them yourself, those are also the events you have the option of handling if they impact your application. Again, you will only need to handle the ones that would cause a change in your application, the others can be ignored. Based on an application I wrote that checks all the activities in the system (including the built-in apps), about 50% use configChanges and about 50% let Android handle it (on both tablets and phones), so the choice is up to you. Regardless of which way you pick, make sure to do the necessary testing.

Re: [android-developers] SQLite slow
Glad to hear you got at least a little speed out of the transactions. On making sure your objects are in sync, I can understand the reasoning behind this. What I tend to do is drop database modifications in a thread and also updates my objects at the end of that thread and then trigger a refresh on the UI when the thread is finished. Are you updating a ton of data each time, or just a few rows here and there? In the response, you said you were reading every row of every table, is there a reason you are doing this? The right SQL statement should prevent you from having to do this. If you are using a ListView, a CursorAdapter helps for dealing with delayed reading automatically. I also write web applications, so if you need a hand with SQL or how to speed up querys, don't hesitate to ask in this thread. I deal with databases that have millions of entries that are join across a ton of tables (and cross database), so I may be able to help speed up your SQL statements.

Thanks Steven, I have implemented transactions and it runs about twice as fast but still have to wait a somewhat smaller fraction of a second. As to the connection it's only opened once and shared across intents. The queries are based on primary keys so I do not see the need to have separate indices. I think what is slowing things down could be the fact that I am reading every single row of every single table just to be on the safe side although things could be done more efficiently but at the risk of complicating the code and introducing bugs in the code. As to implementing the database calls in a separate thread, the reason I didn't do it is that the calling activity needs to display the data from the popped activity retrieving it from the database to make sure it's data remains consistent with the database. But it's true, I could store the data in the database in a separate thread and only read it when the application starts, and just write to it asynchronously. This would really make my app faster. Or I could display a progress bar in between operations. I just want to ensure my objects are always in sync with my database so I have a soreAndRetrieve() data method to make sure this happens at the expense of speed, so maybe it's my own problem.

[android-developers] Re: An application that hosts a set of other applications
You might want to check out the in-app purchase option if you are trying to sell each one separately but also as a group. One option is to have the main package that would include all the applications as sections. Each section could be a limited free version and then use in-app purchase to activate the full version. You could then continue to add sections that started out as free test version and give people the option to activate the new sections they would like to use.

[android-developers] Re: android.text.format.DateFormat.format performance
It is slow and so is String.format(). I've been messing around with it a bit
and here is a *rough *sample I tested:
private static final String DATE_AM_PM[] = { am, pm };
private static Date dFormat = new Date();
private static int iHour, iAMPM;
public static String formatDate( long lTimestamp )
{
dFormat.setTime( lTimestamp );
iHour = dFormat.getHours();
if( iHour == 0 ) { iHour = 12; iAMPM = 0; }
if( iHour == 12 ) { iAMPM = 1; }
else if( iHour 0 iHour 11 ) { iAMPM = 0; }
else if( iHour 12 iHour 24 ) { iHour -= 12; iAMPM = 1; }
return dFormat.getMonth() + / + dFormat.getDay() + / +
(dFormat.getYear() + 1900) + + iHour + : + dFormat.getMinutes() +
DATE_AM_PM[ iAMPM ];
}
As I said, it is rough and doesn't even format the output fully.
I tossed this in my application and used it a bit for a speed test and this
takes up half the time as the formatting routines do. Funny thing is, it has
nothing to do with the date part. It seems the formatters are using a
StringBuffer and some replace functions in the StringBuffer and that is what
is slowing it down. I may try to work up a JNI replacement and see if some
sprintf or fprintf action fix the issue but it may not because of the extra
layer.

Hi,
I am optimizing the critical parts of my code, and I coming to some
ResourceCursorAdapter bindView method.
Though the method is quite long, I saw on traceview that only 2 lines are
taking 40% of the time in traceview; those are call to DateFormat:
((TextView)view.findViewById(R.id.EPG_list_item_hour)).setText(
android.text.format.DateFormat.format(kk:mm,beginTimeMilli) + -
+
android.text.format.DateFormat.format(kk:mm,endTimeMilli));
So just curious: Is there any more efficient way to transform a
timeMillisecond time to a date string (in my case hour/minute)?

On the line that says:

That might not be it, but it's best to use the context that is being passed

I will explain the idea of the application:

This all works fine, I can close the application and
service continue running smoothly. I can stop this service when I
want, reopening the application and changing the button to OFF.
Now the service MyService is waiting any
change of your phone, for each change It send a message like a Toast,
it helps me to know and
check if my service is active, it works
perfectly except when you add the code lines to run an Activity that
contains
simply an image that is where the application is closed, if I leave
only the Toast, it is going great, tells me that
the phone are ringing and informs the incoming phone number.
I create a class that receives the
context and try to launch the Activity in question NewScreen
Here I leave the application code, Any idea?
It took me several days and I dont reach any breakthrough.

You should be able to do this in the fragment itself when it shows itself. Check out the flow-chart on the right hand side of this page: http://developer.android.com/guide/topics/fundamentals/fragments.html#Creating Whenever any fragment gets shown and has already been created, it goes back to onCreateView() and then down the chain. Just make sure to put some sort of refresh in one of the steps that makes the most sense for your application.

See if this helps out:
StatFs sfStats = new StatFs( this.getFilesDir().toString() );
Log.i( SpaceCheck, Free (bytes): + ( sfStats.getAvailableBlocks() *

That should get you the directory to the applications internal storage
(hidden from the user unless rooted) and tell you how much available room
there is in that location.
Here's links to the API documents for those:

[android-developers] Re: major problem with network location fixes and their timestamps
Can't say that I've seen that before. I've only used the GPS a small to medium amount, but seems a little weird. Is the GPS hardware not able to get a fix and causing your logic to drop back to the network GPS? If so, it might be that. Is it happening on multiple different devices and how many devices have you tested it on? You might want to check out the GPS Status app on the market and see if it gets a fix. If it does, it will tell you the time it got it and other information about the fix. Good way of testing the hardware and see if you have an issue there.

BOTTOM LINE (to be detailed further down): It seems as though the Location.getTime() sometimes isn't accurate, in that the system under certain circumstances just updates the time of an old fix and passes it on as though it was new. For us, this is very unfortunate. I think it has something to do with this logline (again in more detail below): 10-12 16:34:47.186: DEBUG/LocationMasfClient(1188): getNetworkLocation(): Returning cache location with accuracy 1072.0 From what i can see, the same location is returned over and over again, just with its timestamp overwritten... EXPLANATION: Have an app that queries location. I register both network and gps, wait for a certain time and takes what comes back from either one and unregister both. Before i register i check the latestknown location and use that if it's not too old. All works fine, process wise, but there's one major issue. I *need* recent fixes, and for that i need to know how old the fix is. I therefore utilize location.getTime() against the system.currenttimillis to see how old it is. However, we see in certain scenarios, that the fix coming back, with a recent timestamp (often under a second!) is for a location where we know that the phone hasn't been at for over 30 minutes!

[android-developers] Re: integrate the youtube player in android app
You normally don't add the YouTube player into your application, you call an ACTION_VIEW intent on a YouTube URL. Intent iVisitSite = new Intent( Intent.ACTION_VIEW, Uri.parse( YOUTUBE_URL_HERE ) ); startActivity( iVisitSite ); I think some people have tried to get it to work in a WebView, but you'd have to Google search that.

Re: [android-developers] SQLite slow
If you aren't, try using transactions:
dbHandle.beginTransaction();
lReturn = dbHandle.insert( sTable, null, cvEntry ); // Update and delete
here also
dbHandle.setTransactionSuccessful();
dbHandle.endTransaction();
If you do multiple inserts/updates/deletes where you target specific rows
for a reason you can't include them all in one query, add more statements
between the beginTransaction and the setTransactionSuccessful.

Yes when I run sqlite3 from adb shell it is fast, but for some

opened it takes more than half a second which really slows
down the user experience.

[android-developers] Re: Writing to External Storage Help
That still should work fine.
/mnt/sdcard on the Bionic is the internal memory and will never be removed
so you shouldn't have any issue using it unless there is something wrong
with the hardware.
/mnt/sdcard-ext is the SD card itself and can be mounted/unmounted etc.
You can try something like this to see what is available to you:
File fMount = new File( /mnt );
File[] fMountPoints = fMount.listFiles();
for( File fCheck : fMountPoints )
{
Log.i( SDCheck, Found: + fCheck.getName() + - Writable: +
fCheck.canWrite() );
}
I tried this on my Bionic and it worked great and everything in there is not
writable except the two SD Card mount points.
I haven't found a way to get the system to tell me if there is more than one
SD Card mounted. Since even the internal memory on devices is now showing
as the SD Card, hopefully ICS will give us a way to figure this out
better.
Unless someone else knows how to get Android to tell you about the SD
Cards mount points, you can use the above to find out which directories are
writable to you and these should be the SD Cards. I don't think they will
be changing the /mnt mounting point any time soon, but you never know, so
just be on the lookout if you use this. You may want to filter out anything
starting with a dot also. I found there is some hidden and writable (or at
least marked writable) files/directories in there on at least one of my
devices that's a dot file.
You can always find the places you can write with that and give your users a
chance to pick which one they want for your application to use.

I am using Environment.getExternalStorageDirectory() to get the

to get the path of external storage. From there I am creating a
directory, a sub directory, and moving a file. This works perfectly
fine for a majority of users, however more recently I have had reports
of it failing this process.
Two examples were the Atrix and the Bionic.
It appears that some devices are reporting wrong information when
using Environment.getExternalStorageDirectory(). It appears to return /
mnt/sdcard when in reality it looks like the path should be /mnt/
sdcard-ext. This causes an exception to occur where it is trying to
make a directory in the wrong location.
Can someone shed some light on how I am supposed to handle this? Am I
supposed to be using something other than getExternal? What am I
supposed to do if the devices return wrong information? I really don't
want to have to tell someone its not my problem, contact their

It seems like you may want to design a custom view object for your calendar so you can just copy/paste that into any other project you use. Then customize the calendar to fit what you want in that specific application. If you want to leave it as an application, TreKing is right in saying you can't embed it.

[android-developers] Re: time picker: soft keyboard problems: cannot read time
Hey John,
You've run into the focus bug (or feature) with the TimePicker. It doesn't
update the time put in by a keyboard until it loses focus.
Try tossing a TimePicker.clearFocus() in the mix somewhere. If you use it in
a dialog, call it on the TimePicker view when you go to dismiss the dialog
and read the values after the clearFocus(). If it is somewhere else, you can
also use the requestFocus() on other views to pull it away and then read the
TimePicker.

Re: [android-developers] Using drawable resources efficiently
After additional testing, I've confirmed that the mutate() option doesn't allow the use of one Drawable on multiple view under the following conditions unless there is a trick to it that I'm missing. 1. Using a CursorAdapter with a ListView (Using newView and bindView, haven't tried with getView as it would take a rework of code) 2. GradientDrawable created programmatically (the only way you can do it and customize the gradient colors on the fly) 3. GradientDrawable assigned with setBackgroundDrawable() 4. ListView items having different heights and/or widths Maybe the state of the drawable doesn't include the height and width of the object, but there isn't really anything that shows what is included in the state. Seeing that the alpha was included, one would have thought things like size would have also been included. I'd like to go to reusable Drawables as it would simply things, so if anyone has a viable solution, that would be great.

Re: [android-developers] Re: textView Clears on Rotation
I'm compiling a list of things that need to happen in both cases. So far it looks like a lot bigger challenge to not use the android:configChanges than to use it. I've read the optimization post plenty of times and do understand it, but I'd like to get the big picture for the usages of both to be able to decide which is better in certain cases. Here's a few of the issues I'm trying to find good solutions to when *not*using configChanges: 1. Window states are not saved. ListView scroll locations, ExpandedListView drop-downs and scroll locations, ScrollView locations, etc. 2. OpenGL VBOs and textures loaded into memory get destroyed and have to be reprocessed and copied back into memory along with the GLSurfaceView state information 3. Special consideration now has to be taken with AsyncTasks since they are linked to the UI and need to be stopped, location of processing saved and restarted 4. Special consideration for threading, but not quite as much as AsyncTasks 5. Special consideration needs to be taken for the things saved in the bundle so you don't leak the previous context. This could get tricky because I'm sure a lot of people pass a context to objects or blend data and view objects *With* configChanges: 1. Layout may need to be changed on rotation 2. Other unknown issues With the resources being automatically swapped out by Android, a simple refresh on screen elements would pick up a new language if you needed to support that. That also includes any images that might be swapped over, but as I have to refresh the state of my windows even when it isn't rotated, this is already written in the base application anyways. To me it's also wrong to forget about the general case, i.e. other config changes and the out of memory killer (and maybe more cases I can't think of right now). This part did catch my eye and it is what I was wondering. Is there something that the configChanges does to cause internal issues because it is bugged? All of the configuration changes are fairly straight forward and documented, but if there is some issue internally, would be nice to know. In an effort for this discussion not to go to waste, I'm trying to get the full picture compiled together on what has to happen on both so that I can get a post on my site or somewhere to help others. I know we all see this question fly by on this group (and on other help areas) all the time, so I figure a post of the compiled pros and cons of each would be helpful. Anyone that would like to toss in additional information about the things you have to deal with on either occasion (using configChanges or not), please do so and I will compile it for us for future reference.

[android-developers] Re: Multithreading in Android?
Android is designed to keep applications around in a paused state unless it needs the memory back. If it does need memory from currently paused applications, it will close them to free up the required memory. This is to make sure the user can move around faster and provide a better user experience. What you are seeing is normal and you don't have to worry about closing background windows as Android will handle it for you when it needs to.

[android-developers] Re: layout changes when on-screen keyboard shows/hides suggestions
Try making the Button and the EditText height match_parent (or fill_parent) instead of wrap_content. I've run into this before and I think the Button and EditText aren't quite the same initial height when using wrap_content. When the keyboard pops up, it might be pushing the Button up to the top of your LinearLayout because the Button is just a slight bit smaller than the EditText.

[android-developers] Re: scrollview can't work programmatically
I think it has to do with you are extending ViewGroup. Try this redone code
where it is extending LinearLayout instead and see if it does what you need
it to.
public class MyView extends LinearLayout
{
ScrollView myScrollView;
TextView tv;
public MyView( Context context )
{
super(context);
myScrollView = new ScrollView(context);
myScrollView.setBackgroundColor(0xfff00fff);
tv = new TextView(context);
tv.setTextColor( Color.BLACK );
tv.setText(sadfasdfasdfasdfasdfasdfasdfsadfsadf);
tv.setHeight(5000);
tv.setWidth(3200);
myScrollView.addView( tv, new LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT ) );
addView( myScrollView, new LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT ) );
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b)
{
int width = r-l;
int height =b-t;
myScrollView .layout(0, 0, width, height-100);
}
}
It works in a test situation, but not sure it will do what you want in your
application, so give it a shot and let us know.

Hello guys,
I want to use scrollview in my app. I tried to add a text view into
the scrollview, but I can't see anything rendered, except the
background color of the scroll view.
here is how I did it:
public class MyView extends ViewGroup
{
ScrollView myScrollview;
Textview tv;
public MyView(Context context) {
myScrollView = new ScrollView(context);
myScrollView.setBackgroundColor(0xfff00fff);
textview=new TextView(context);
textview.setLayoutParams(new
LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
textview.setLayoutParams(params)
textview.setText(sadfasdfasdfasdfasdfasdfasdfsadfsadf);
textview.layout(0, 0, 1000, 2000);
textview.setHeight(5000);
textview.setWidth(3200);
myScrollView .addView(tv);
addView(myScrollview);
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b)
{
// TODO Auto-generated method stub
int width = r-l;
int height =b-t;
myScrollView .layout(0, 0, width, height-100);
}
}
I found almost all the scrollview tutorial are using xml to define the
view. But I want to do it in a programmatic way. But anyway, I also
tried xml.
I copied Romain Guy's xml from here for testing :http://www.curious-
creature.org/2010/08/15/scrollviews-handy-trick/
The xml scrollview by itself is correct, if I create this scrollview
and add it to the activity, using
scrollview= (ScrollView)
getLayoutInflater().inflate(R.layout.scrollviewid,null);
setContentView(scrollview);
or setContentView(R.layout.scrollviewid);
it worked. However, if I want to make the scrollview a child view of
some other view, again I could only see the background of the
scrollview. nothing inside is rendered:
public class MyView extends ViewGroup
{
ScrollView myScrollview;
public MyView(Activity activity,Context context)
{
super(context);
myScrollview= (ScrollView)
activity.getLayoutInflater().inflate(R.layout.restaurantcategoryselectorviewlayout,null);
myScrollview.setBackgroundColor(0xfff00fff);
addView(myScrollview);
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b)
{
// TODO Auto-generated method stub
int width = r-l;
int height =b-t;
myScrollview.layout(0, 0, width, height-100);
}
}
What's wrong with my code? Is there any example of creating scrollview
with program not xml?
Also, are those java source code of android also at kernel.org? since
the git service is down, where can I download android source code?
Thanks you!

Re: [android-developers] Re: textView Clears on Rotation
*TreKing,* This is true, but he didn't ask about that. He just asked about a way for an EditText to keep the text it has on a rotate. The easiest and fastest way to solve that particular problem is the configChanges XML attribute. You'll note that I said their may be a need for other options if they needed it to do additional things other than just handle a rotate. There is no need to code complicated functions to do something simple.

[android-developers] Re: unreasonable NullPointerException in onDestroy()
Without code samples, I don't think anyone is going to be able to help you
find your issue. I use this all the time and the only time I have seen it
not work was when I made a mistake somewhere else in the code.
I do usually do a null check on things in the onDestory before I use them
because my code can get more complicated as it goes. I end up changing
variables along the way forgetting I'm cleaning them up at the end.
If you do find a serious bug like this, you'd definitely want to go through
the steps to reproduce it and post a bug reports in the Android Issue
Tracker if someone else hasn't found it already.

Re: [android-developers] Re: textView Clears on Rotation
*TreKing,* If you choose to ignore a well documented feature given to us by the Android team, that's your prerogative. As for the rest of us, we'll decide when we prefer to use one feature over another. *King Salamon*, As stated previously, regardless of which way you choose to do it (neither is correct or incorrect), just read up on the things you need to handle to make them work like you need them to. If you really want to save a state long-term, I would suggest you also look at SharedPreferences: http://developer.android.com/reference/android/content/SharedPreferences.html You aren't guaranteed your state will still be there even if you do save it in a bundle. You should treat the state of your application as volatile at all times. If a state or piece of data is really important to keep around, commit it to disk immediately via the SharedPreferences or another method like a custom file, database, etc.. Devices are constantly switching states even when we don't want them to. Battery dying, being dropped, locking up, and tons of others things make sure the mobile environment is never guaranteed, so write accordingly.

LOL - so since he didn't ask for for a method that covers the case I mentioned, it's OK to give him a limited solution? He just asked about a way for an EditText to keep the text it has on a rotate. What people ask on this list is usually very different from the problem they're actually having. The easiest and fastest way to solve that particular problem is the configChanges XML attribute. Easiest and fastest, but technically incorrect. He's probably asking specifically about rotate because that's also the easiest and fastest way to see the issue. But, as I mentioned, it's not the only way and the OP should be completely aware of that before going with a strategy that will only hide the problem in one particular scenario. You'll note that I said their may be a need for other options if they needed it to do additional things other than just handle a rotate. You mentioned the case of different layouts which doesn't cover the case of leaving the app, waiting a while, and coming back to it (AFAIK). There are probably others. There is no need to code complicated functions to do something simple. Fix it the simplest way possible and then add to it if other things arise. Sure, but if the simplest way possible is known to have issues, you're not really doing the OP any favors, are you? Now he'll waste time fixing it the simplest way, then eventually having to come back and fix it the right way. Why not have him do it the right way from get-go if you can? It's not like using the save and restore methods is that complicated. IMHO, the configChanges attributes are for use when you know exactly what you're doing with them and why. Using them to get around saving / restoring state is a fragile kludge for people that can't figure out how to do it correctly. People should be encouraged to figure out how to do this the right way so it works in every scenario and not use what amounts to a hack to solve the most common instance of configuration change. And I say all this because I've seen way to many people ask about this exact scenario in this group. - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.
