[android-developers] Supporting ClientCertificates in Android Webview for 4.4
Hi, My app needs to support Client Certificate authentication from my Webview. Until 4.3 , i could do it by accessing internal APIs for onReceivedClientCertRequest() But in 4.4 it seems that the Browser implementation has changed to Chromium browser which has removed the classback for Client certificates. Is there any way to support Client Certificates on Kitkat OS ? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Contact shows as part of Groups Tab and not
I create a group programatically as
private void createGroup() {
ArrayListContentProviderOperation ops = new
ArrayListContentProviderOperation();
ops.add(ContentProviderOperation
.newInsert(ContactsContract.Groups.CONTENT_URI)
.withValue(ContactsContract.Groups.TITLE, SRI).build());
try {
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
} catch (Exception e) {
Log.e(Error, e.toString());
}
}
If i try to add a contact group in this
manner(manually/programatically) on Samsung Europa (Galaxy5), it
succeeds, but if i Add a contact and link to this group, the contact
does not show in Contacts Tab but only in Groups tab under that group.
If i remove the Contact from that group, then it shows under contacts
tab.Why is this happening ?
Regards,
Alok

Re: [android-developers] Problem with adjustPan andadjustResize
@Dianne , If i use adjustResize only then it works on most of the devices, its observed that on an EditText keyboard comes up but the focus of the Edittext goes and user has to click again on the Edittext, which is not natural behaviour. If i use adjustPan only , then the screen does not scroll to the bottom when SoftKeyboard is open. When both are given , then worked fine on a few devices like Samsung Europa but on most of the devices either of the issues mentioned above was observed. Regards, Alok.

Re: [android-developers] Problem with adjustPan andadjustResize
One thing i am doing is adding Edittexts defined in XML to a ListView at runtime according to number of fields.Is that causing the problem ? On Tue, Jan 25, 2011 at 2:33 PM, Dianne Hackborn hack...@android.com wrote: Using adjustResize does not cause an edit text to lose focus in any way. The only thing it does is cause your UI to relayout for the new window size. I don't know what you are doing, but the vast majority of applications you interact with just use adjustResize with a regular view hierarchy, and they work fine.

[android-developers] Problem passing Unicode string through JSON request
Hi, I am having a unicode string \u3403 which is actualy some japansee character I want to pass it through a JSON object. So i put the value as say String str = \u3403 jsonObject.put(name,str); When i do this the json object internally adds another escape sequence as \\u3403, and the request string has two \ slashes. This is interpreted wrongly by the server as it does not detect unicode name. What can i do for this ?

Re: [android-developers] Problem passing Unicode string through JSON request
Thanks Daniel for your response,
In my app, the user enters a name in japanese language which is to be
sent to server in a JSON request.The server expects the name parameter
in form of a UTF-8 encoded string.
So the encoding of source code should not matter.Here is the sample code
public static String EncodeJson(String strJson)
{
try
{
String strHex = null;
for (int i = 0; i strJson.length(); i++)
{
try{
//char c = strJson.charAt(i);
// int j = (int) c;
// System.out.println(ASCII OF +c + = + j + .);
//System.out.println(strJson.charAt(i), 10=
+Integer.parseInt(+strJson.charAt(i), 10));
if ( strJson.charAt(i) = 126)
{
String start = strJson.substring(0, i);
String end = strJson.substring(i + 1);
int jsonChar = strJson.charAt(i); // new
string(strJson[i], 1);
strHex = 000 + Integer.toHexString(jsonChar);
strHex = strHex.toUpperCase();
strJson = start + \\u +
strHex.substring(strHex.length()-4)+ end;
i += 5;
}
}catch(Exception e){
System.out.println( Exception -
strJson.charAt(i)= +strJson.charAt(i));
}
}
return strJson;
}
catch (Exception ex)
{
Log.i(Encode, ex.toString());
return strJson;
}
}
The output of this method is passed to JSON object using its put
method.At this point an additional \ gets added to the parameter
due to which the server does not recognize this as a valid UTF string
Thanks,
Alok.

Alok,
\u3403 is not a unicode string, but a string that has hex code of an
unicode character in it. It can be unicode encoded or its encoding can
be anything else really.
Since \ is a special character and has extra meaning in Java String
class, it gets escaped by escape character, which is \. Now you
know, what is the extra meaning of \ ;-)
Now JSON should not have any problems with parsing such
character/string, even when double escaped. Make sure that your server
is correctly configured for use of unicode.
Also try sending the actual character (paste it from some place that
generates a character based on its hex code), but please make sure
that your source code is unicode encoded, otherwise it will not work.
Daniel

Re: [android-developers] Problem passing Unicode string through JSON request
I am using Androids JSON library, The extra \ in the line strJson = start + \\u + strHex.substring(strHex.length()-4)+ end; has to be added as an escape sequence else the code does not compile. I don't understand the need for the EncodeJson function. -Though internally java might be storing as UCS-16, when passing to the web service , the web service expectes the parameter to be in UTF-8 encoded string.

[android-developers] Error with DB onUpgrade
Hi, I have multiple databases in my app.At the start of the application , i initialize all the databases and access columns from the required tables.What i did is , for one of the databases i incremented the version of the DB. So now i have started getting error of No Such table say ABCD while compiling query.This table is in another DB than the updated DB. I dont have any code in the onUpgrade right now.. Is there any thing thats striking anyone why this behavior is happening? Is there anything that happens in the onUpgrade method that causes all the DBs to be inaccessable temporarily. I am saying this because if i place a breakpoint in onUpgrade and debug , then i wait for a few seconds on the 1st stmt in onUpgrade and then everything works fine... -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Error with DB onUpgrade
I am following this
http://efreedom.com/Question/1-3505900/SQLiteOpenHelper-OnUpgrade-Confusion-Android
What do u mean by saying SQL open helper for all code paths
I am using the standard code for
public void open() throws SQLException {
db = DBHelper.getWritableDatabase();
}
The open method is called for each database seperately.

Re: [android-developers] Error with DB onUpgrade
Ok.. thanks One more thing .. Here for the problem i am facing.. IS that i need to take care that i access the tables only after onUpgrade completes execution ? On Fri, Oct 22, 2010 at 6:34 PM, Kostya Vasilyev kmans...@gmail.com wrote: No, onUpgrade doesn't delete any data, tables, or databases. It's just a callback in your code that's called by Android when the desired database version doesn't match the existing database version. Your callback can do whatever it needs to bring the database schema up to date - typically, adding columns or tables. So if your code just does ALTER TABLE ADD COLUMN, you don't need to do anything special to preserve existing data. -- Kostya 22.10.2010 16:56, Alok Kulkarni пишет: Yeah ill do my best..

Yes, that's what I meant.
Always call getWritableDatabase, and don't call SQLiteDatabase.openDatabase
- are you, perhaps, somewhere in your code?
In the link you posted, table upgrades are done by renaming the old table
and creating a new table from scratch, then copying the data. So there is
the time period when the table doesn't exist. Most likely, this is the
reason why you're seeing your error.
Since you've said that your code is multithreaded, I think what happens is,
one thread starts upgrading the database, while another thread starts to
make queires, or perhaps tries to perform an upgrade as well.
To fix this issue, you need to add thread synchronization around opening the
database, to avoid concurrent access until the database has been fully
upgraded.

[android-developers] Issue of getting keyEvents for device having both hard and soft keyboard.
Hi all, I am developing the application where i want to capture all 'keyEvents' in my code. I used onKeyDown(int keyCode, KeyEvent event) to achieve this. But it has some flaw in it, 1.When i have device with Hardware keyboard, onKeyDown works well with it. But when i use Virtual keyboard it fails. 2. Now if i use device with only Softkeyboard, having no Hardware keyboard, onKeyDown works well with Virtual keyboard. So, my difficulty is to detect the onKeyDown for the device which has got Hardware keyboard user uses the Soft keyboard.

[android-developers] Problem getting width and height of Device programatically for QVGA devices.
Hi all, I want to get the width and height of my device to know what type device it is ie QVGA, HVGA ,WVGA.. Also i need to adjust some layouts according to width and height of the screen. I tried following methods but its not working. 1) 1. /* First, get the Display from the WindowManager */ 2. Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay(); 3. 4. /* Now we can retrieve all display-related infos */ 5. int width = display.getWidth(); 6. int height = display.getHeight(); 7. int orientation = display.getOrientation(); 2) width = getResources().getDisplayMetrics().widthPixels; height = getResources().getDisplayMetrics().heightPixels; 3) int ht; int wt; DisplayMetrics displaymetrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(displaymetrics); ht = displaymetrics.heightPixels; wt = displaymetrics.widthPixels; All these methods return wrong width and height for the 240x320 devices namely Samsung Europa and Alcatel which i have. Width = 320 Height = 240.. This is wierd as some of the critical functionality is getting hampered .. I think this is really a basic thing which shd be correctly provided.

Re: [android-developers] Problem getting width and height of Device programatically for QVGA devices.
So is it that of API level is 3, then it wont calculate the width and height and just assume the emulated HVGA version as 320 x 427.. But what is 427 i mean it shd be 480 rite ?? 2010/8/23 Alok Kulkarni kulsu...@gmail.com Ok.. here is what the case is..

[android-developers] ListView paint issue in landscape mode.Width remains as in Portrait mode
Hi, I am having a listview in my App which shows perfectly in Portrait mode.But when i change orientation to landscape , sometimes the width remains as that of Portrait mode.Even the scrollbar for the list comes at the center and remaining part of the screen remains balcked out.This happens only with the list view.Other views show perfectly.I have designed the layouts such that the Portrait layouts look feel proportionate in landscape mode . I want to avoid restarting the activity so i have not put the layouts in the landscape folder. I tried invalidating the listview in onConfigurationChanged() but of no use. When i navigate in the list in landscape mode , the width automatically gets adjusted.Any help in this regard will be of great use :) Thanks, Alok. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] cursor.moveToFirst() blocking UI
Hi Mark,
As i said , i am doing the operation in a background thread.
I also know that cursor.moveToFirst() causes the data to be accessed at that
point.
Here is the code
public void getAllSongIdsOffset(int offset, int limit) {
int nTrackId;
try {
SQLiteDatabase db =
InventoryManager.inventoryDB.getConnection();
Cursor mCursor;
int index = 0;
mCursor = db.rawQuery(
select distinct id from tracks order by tracks.namelimit
+ limit + offset + offset + , null);
SQLiteDatabase.releaseMemory();
if (mCursor != null) {
Log.i(VALUE-, Before movetoFirst +
System.currentTimeMillis());
mCursor.moveToFirst();
Log.i(VALUE-, After movetoFirst +
System.currentTimeMillis());
if (mCursor.getCount() == 0) {
mCursor.close();
SQLiteDatabase.releaseMemory();
System.gc();
return;
}
do {
// songIds[index] = new Integer(mCursor.getInt(0));
mediaIdArray.set(offset + index, mCursor
.getInt(0));
index++;
} while (mCursor.moveToNext());
}
mCursor.close();
mCursor = null;
} catch (Exception e) {
e.printStackTrace();
} finally {
InventoryManager.inventoryDB.releaseConnection();
}
SQLiteDatabase.releaseMemory();
}
private class ListThread extends Thread {
public void run() {
int size = mediaIdArray.size();
while (offset = InventoryManager.songs.getAllSongCount()) {
try {
Thread.sleep(1);
int cnt = offset + limit;
if (cnt size)
cnt = size;
InventoryManager.songs.getAllSongIdsOffset(offset, limit);
offset += 1000;
ListScreenHandler
.sendEmptyMessage(ScreenConstants.NOTIFYDATASETCHANGED);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
If i dont do a Thread.sleep... the UI gets completely blocked until all the
records are fetched.\
To update the UI i am calling a handler.
Thanks ,
Alok.

Re: [android-developers] cursor.moveToFirst() blocking UI
Hi Mark,
Thanks for your reply. What i did was i removed the System.gc() as well as
the handler call.
Considering the code from above snippet.
Log.i(VALUE-, Before movetoFirst +
System.currentTimeMillis());
mCursor.moveToFirst();
Log.i(VALUE-, After movetoFirst + System.currentTimeMillis());
Output :-
Before movetoFirst 1279628503040
After movetoFirst1279628508063
This clearly shows a difference of 5 seconds.(My emulator is slow.On device
it takes 2 to 3 seconds)
Thanks,
Alok.

With respect to your If i dont do a Thread.sleep... the UI gets
completely blocked until all the records are fetched., the problem
would appear to be in whatever your Handler is doing, or possibly just
due to all the garbage collection you are doing. None of the code you
show here, other than the GC, should block the UI thread, from what I
can tell.
Bear in mind that the code you have here is only copying a bunch of ID
values. Assuming your UI is displaying things other than ID numbers,
there must be other database I/O going on -- perhaps it is that I/O
that is causing your problem.

Re: [android-developers] cursor.moveToFirst() blocking UI
Problem Solved.. The problem was that i was querying on the tracks database for 1000 songs.. At the same time, scrolling the list would make a call to the same tracks table. This is synchronous in Android using the same DB object. So the solution was to create a seperate DB object as getReadableDatabase for the 3 songs list query.. UI does not block now..Yippee I am sorry for the incorrect inference that i got earlier .. Thanks And Regards, Alok.

Re: [android-developers] Re: Maintaining the state when changing the orientation
Thanks Dianne for your response. I have solved the leaks almost completely . What wrong i was doing is i was also saving the array of list items drawn on the UI and reassigning it to the new activity.It takes some time to understand what really should be saved and what not to be saved , also understanding saving what exactly causes a memory leak.There are a few leaks after i start playing a song.But i need to analyze further and get back.

What I've done in order to pick up where I left off after a rotation change (or, for that matter, when the user calls the app from the main screen) is to start and bind a Service that I bind again when the app comes out at the other end. Implement getters and setters like you normally would to access the relevant data. The SDK contains a pretty good example how to do all that which you can use as a blueprint. Hi, this doesn't really save you anything. If you are just keeping the service running during the change, then it isn't any better than keeping that stuff in globals. If you are actually keeping the service running all the time just to not have to persist your state... please do not do that, as it harms the overall user experience because you are telling the system your app needs to run all the time and it needs to kill other things to keep you running. (And we are increasingly going to have facilities for users to find out about apps doing this kind of stuff and deal with it in various ways. This is becoming my #1 target for making a better user experience.) If your application is really something that has so much going on that it needs to always be running, then you can make a foreground service with its associated notification. Then the user knows it is running, and knows how to get it to go away if that is not what they want. The downside is that there's a risk the service gets killed as the system is scraping for resources, but personally I haven't seen this happen for a service that's bound to an UI thread. There's people on the list who know much more about what's going on under the hood in that regard, perhaps they can chime in. The service and your activity all run in the same process. If the activity is in the foreground (which is the case during a configuration change), then the process will not be killed. It doesn't matter at all that there is a service there or that you are binding to it or anything like that. If you are using a service to keep yourself around in the background... well, these days we pretty aggressively throw long-running services farther into the background, to basically guarantee they will always eventually get killed (and then restarted in a clean process). -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

[android-developers] Re: Maintaining the state when changing the orientation
Currently i am having handlers in my code which update th ui. But it seems they are not having any effect on ui when i change the orientation.the handlers get called but do not have any effect on ui.is there any special handling that needs to be done in case of handlers?

To capture that state before the activity is killed, you can implement an onSaveInstanceState() method for the activity. Android calls this method before making the activity vulnerable to being destroyed — that is, before onPause() is called. It passes the method a Bundle object where you can record the dynamic state of the activity as name-value pairs. When the activity is again started, the Bundle is passed both to onCreate() and to a method that's called after onStart(), onRestoreInstanceState(), so that either or both of them can recreate the captured state. Unlike onPause() and the other methods discussed earlier, onSaveInstanceState() and onRestoreInstanceState() are not lifecycle methods. They are not always called. For example, Android calls onSaveInstanceState() before the activity becomes vulnerable to being destroyed by the system, but does not bother calling it when the instance is actually being destroyed by a user action (such as pressing the BACK key). In that case, the user won't expect to return to the activity, so there's no reason to save its state. Because onSaveInstanceState() is not always called, you should use it only to record the transient state of the activity, not to store persistent data. Use onPause() for that purpose instead. http://developer.android.com/intl/de/reference/android/app/Activity.html Configuration Changes If the configuration of the device (as defined by the Resources.Configuration class) changes, then anything displaying a user interface will need to update to match that configuration. Because Activity is the primary mechanism for interacting with the user, it includes special support for handling configuration changes. Unless you specify otherwise, a configuration change (such as a change in screen orientation, language, input devices, etc) will cause your current activity to be destroyed, going through the normal activity lifecycle process of onPause(), onStop(), and onDestroy() as appropriate. If the activity had been in the foreground or visible to the user, once onDestroy() is called in that instance then a new instance of the activity will be created, with whatever savedInstanceState the previous instance had generated from onSaveInstanceState(Bundle). This is done because any application resource, including layout files, can change based on any configuration value. Thus the only safe way to handle a configuration change is to re-retrieve all resources, including layouts, drawables, and strings. Because activities must already know how to save their state and re-create themselves from that state, this is a convenient way to have an activity restart itself with a new configuration. In some special cases, you may want to bypass restarting of your activity based on one or more types of configuration changes. This is done with the android:configChanges attribute in its manifest. For any types of configuration changes you say that you handle there, you will receive a call to your current activity's onConfigurationChanged(Configuration) method instead of being restarted. If a configuration change involves any that you do not handle, however, the activity will still be restarted and onConfigurationChanged(Configuration) will not be called. That should get you going in the right direction. There is also onRetainNonConfigurationInstance (Activity method) but it's not what you should rely on (can be used to optimize), but the basics are the onSaveInstanceState and onRestoreInstanceState methods.

[android-developers] OnOrientationChanged leaks in ListView
Hi, I am having a ListView with custom ArrayAdapter.For defining a list item i have my own class ListItem which stores all info including list item images, and other textual info in it. I have handled orientation change in onRetainNonConfigurationInstance() in which i save the array of ListItems in another object.. and when the Activity is recreated i reassign the array of list items to those of the activity. Then i create an ArrayAdapter accordingly .I use adb shell procrank and find out that i am leaking memory everytime i change orientation. I have debugged through and found out that the leak is in arraylist of list items itself.What wrong am i doing here ?

.
Even if i use Wifi for connection , it is observed the if the SIM is not

results.
Is this a device specific problem ? I have a Moto Blurr to but its not
unlocked here for SIM services.
Please help . :)

Re: [android-developers] Re: Problem with StateListDrawables not found in 1.5 but there from 1.6 onwards
Guys , I finally found the solution for my original problem.So thought of sharing it if someone has the same in the future. Using the 3 images itself ,my problem was solved by adding a zero padding explicitly android:paddingLeft=0dip android:paddingRight=0dip android:paddingTop=0dip android:paddingBottom=0dip Maybe Android 1.5 is taking padding 0 dip for the compound drawables but later on its adding some padding by default from 1.6 and specifying padding as 0 explicitly solves the problem.This solution was found just by fluke..But it has solved a major headache for me ..

Re: [android-developers] Re: Maintaining the state when changing the orientation
Hi guys , thanks for the replys, @Sanjay , i have taken care in case of ArrayAdapter for ListViews I could successfully do save the state of application and also the handlers problem was solved. What i did is that i used a Main class which extends Application, whenever onCreate of my Activity gets called , i assign the Activity reference to a Main class Activity variable.This happens each time onCreate is called. @JP, Actually the application is very huge currently. So i will slowly move towards Service implementation, but for current releases i need to do changes in the current architecture itself. But currently i am facing the issue of going OutOfMemory if i keep on changing the layout from landscape to portratit and vice versa. I have to take all the drawable images from a runtime folder under my application as i have themes implementation and themes images come from server. So i assign drawables at runtime to all the widgets. When the orientation changes , i reassign the drawables to all widgets.I have taken care of making the objects null.. And views get null when onDestroy is called. Also i havent kept the reference of activity anywhere after onDestroy is called.. IS there anything wrong thats striking to anyone right now ?

Like in your case, I have apps that need to keep (hundreds of) objects and state variables that require retention regardless of what's going on at the UI level. What I've done in order to pick up where I left off after a rotation change (or, for that matter, when the user calls the app from the main screen) is to start and bind a Service that I bind again when the app comes out at the other end. Implement getters and setters like you normally would to access the relevant data. The SDK contains a pretty good example how to do all that which you can use as a blueprint. The downside is that there's a risk the service gets killed as the system is scraping for resources, but personally I haven't seen this happen for a service that's bound to an UI thread. There's people on the list who know much more about what's going on under the hood in that regard, perhaps they can chime in. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Maintaining the state when changing the orientation
Ok , i have succeeded in many parts of the app supporting the landscape mode, i am now facing a major problem in case of Handlers. I have many handlers for updating the UI . But they dont seem to work when i change Orientation.They behave a bit werdly actually.For example, i have a Play button which plays a song.A few set of events occur and then a handler is called from non ui thread to update the button icon.The icon of the button toggles to Pause as expected.Now when i change the orientaion, and do the same activity, the icon does not update. Now when i change the orientation again, the icon has been updated automatically? Is there any issue in case of handlers in case of orientation change?The handlers seem to get called when i checked using the debug mode ,but do not have any effect it seems. Thanks, Alok.

[android-developers] Application Upgrade Related Questions
Hi , i wanted to ask a question regarding the upgrading of my application. I have tested the following thing. Put the new version of the APK on a server.Open the link of the APK from the mobile browser .The mobile automatically downloads the APK and asks for installation.Once installed , the application has got upgraded. Now can i do this thing programatically ? I want that once the user starts the application , a web service will be called internally which will check that an application upgrade is available. If its available , i want to internally download the APK on the device once the user says Yes. And then it should get installed automatically. I can download a given file from a given server on the device on my SDCard /application folder. How can i invoke an automatic installation procedure? Can i do this programatically ?

[android-developers] Problem with StateListDrawables not found in 1.5 but there from 1.6 onwards
Hi ,
I am having the following code for drawing buttons in my project.
I am having a button which has three images for 1 button .Namely one image
for the rectangle and 2 images for the left and right side curves
respectively.
When the button has focus , there is another three images for focus and
similarly 3 images when button is pressed.
Following is the code.
public void setButtonStyle(Button btn) {
//The middle rectangle
StateListDrawable drawables = new StateListDrawable();
drawables.addState(new int[] { stateFocused, -statePressed },
dButtonMidOverImage);
drawables.addState(new int[] { stateFocused, statePressed },
dButtonMidDownImage);
drawables.addState(new int[] { -stateFocused, statePressed },
dButtonMidDownImage);
drawables.addState(new int[] { -stateChecked }, dButtonMidUpImage);
btn.setBackgroundDrawable(drawables);
//The left curve
StateListDrawable drawablesLeft = new StateListDrawable();
drawablesLeft.addState(new int[] { stateFocused, -statePressed },
dButtonLeftOverImage);
drawablesLeft.addState(new int[] { stateFocused, statePressed },
dButtonLeftDownImage);
drawablesLeft.addState(new int[] { -stateFocused, statePressed },
dButtonLeftDownImage);
drawablesLeft.addState(new int[] { -stateChecked },
dButtonLeftUpImage);
StateListDrawable drawablesRight = new StateListDrawable();
drawablesRight.addState(new int[] { stateFocused, -statePressed },
dButtonRightOverImage);
//The right curve
drawablesRight.addState(new int[] { stateFocused, statePressed },
dButtonRightDownImage);
drawablesRight.addState(new int[] { -stateFocused, statePressed },
dButtonRightDownImage);
drawablesRight.addState(new int[] { -stateChecked },
dButtonRightUpImage);
//Compound drawables set for left and right side.
btn.setCompoundDrawablesWithIntrinsicBounds(drawablesLeft, null,
drawablesRight, null);
}
This thing which i have done runtime can be done in the XML too , but i want
to change themes runtime so my images for button will also change runtime.
If i do the code in the XML it works fine on both Android 1.5 as well as
Android 1.6 .But doing it in code distorts the images for 1.6 emulator.
I have attached the screen shot of the buttons on both 1.5 and 1.6
emulators.As you can see, the left and right curve images come almost to the
center and the centre image is expanded in 1.6 emulator. The same problem is
seen on HTC Desire (Android2.1)
Is there something wrong that i am doing . Is there any workaround for this
problem.
Thanks ,
Alok.,

Re: [android-developers] Problem with StateListDrawables not found in 1.5 but there from 1.6 onwards
Thanks for the link Kostya, But my problem is that i cannot have my images under drawable folder and also cannot specify the image path in my XML for layout as and when the user wishes to change the theme , a new theme will be downloaded from the server and the new set of images will be loaded at runtime ,, So if my button has a yellow color when it has focus it might become red when user changes theme.So all the three images for a button will change at runtime..So all my drawables need to be kept in the runtime application folder ie data/data/appPackage/themes which i am doing curently.. Is the 9 patch image logic useful in this case ? The statelistdrawable works fine if i have only one image for a Widget.But in case of button i have three images which is not working 1.6 onwards..

[android-developers] EditText Image changing look when given at runtime.
Hi guys, I am having an EditText. If i specify image for the EditText in the layout XML file (android:background) it looks different and looks different when i specify it at runtime EditText et = (EditText)findViewById(R.drawable.et1); et.setBackgroundDrawable(Main.themes.getDrawable(EDRAWABLES.EditTextBackgroundImage)); Both codes point to the same image. When i specify the image at runtime , the EditText leaves a margin at the top and bottom of the cursor in the edittext which does not happen when i do it in XML. I have attached the screenshots of both images. Top image is the one drawn from XML and bottom one is given at runtime. I am not getting the difference ? Actually i am facing similar problems with other Widgets too if i change the logic of specifying the drawable at runtime and not at compile time.. Is this the default SDK behaviour ?

[android-developers] Set Image resource as package path in XML for runtime images
Hi, Can i do this :- Set the image background path as package:imageName Example.. At runtime , my package is com.test.android .Inside that i have an image whose path i want to mention in the XML layout file as android:src = com.test.android/img1 for an ImageButton. I saw an SDK reference for ImageView as android:src = @[+][package:]type:name .. But i am not getting how to use it.. I think it must not be possibe , but if there is any way , please specify.. The reason why i want to do this is that , when i specify a drawable at runtime for my image buttons, i change the images according to Focus received , or onKeyup, KeyDown.. but its not working as expected.When i mention the same thing as style under drawable , it works fine. So if my theme is going to change at runtime , i want to set the drawable at runtime , keepnig the path same in the xml.

Re: [android-developers] Re: Database insertion timings
I do not have any indices for my tables at all.
Each of the tables Artist, Albumn and Songs has 4,5,5 columns respectively.
Using Raw query as Yahel said improves the speed to some extent . Inserting
7000 records takes 18 seconds instead of 22 but thats not much as in total ,
i am going to insert 3 to 4 entries , which will take hell lot of
time..
Using raw queries is not much helpful as the data itself might contain
quotes and double quotes.
Thanks ,

I don't see anything wrong in your code, so only two things come to

- Instead of using ContentValues, try to create an insert sql

any improvement
- Maybe it's not the database writing that is slow but the reading

Re: [android-developers] Re: Database insertion timings
@mobDev, I have followed some links , example
http://www.higherpass.com/Android/Tutorials/Accessing-Data-With-Android-Cursors/3/
where they were doing setTransactionSuccessful before ending transaction.
Removing that statement does not have an effect.
Even if i do say
String tempName = Artist;
String tempVal = Enrique;
int tempId = 0;
for(i = 0;i 7000;i++)
{
tempId++;
addArtistDB(tempID,tempName,tempVal1);
}
It takes 20 seconds .So there is not much time required for accessing the
data i want to put into database. The actual insertion itself is taking so
much time.
As Sqlite is native to Android , i assume it must be fast enough.
One more thing , Same amount of insertions on a Windows Mobile Device ,
using a Third Party SQLite DLL , its taking 5 to 6 seconds..
Its not that i am blaming android , but i am getting frustrated now :( :(
Thanks ,
Alok.

This is a standard class DatabaseHelper extending SQLiteOpenHelper...
private static class DatabaseHelper extends SQLiteOpenHelper {
DatabaseHelper(Context context, String databaseName) {
super(context, databaseName, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
// Nothing to do

Log
.w(Upgrade, Upgrading database from version

db.execSQL(DROP TABLE IF EXISTS titles);

}
}
Then i have

This db object is used to perform insert operations.

doing
this without which its taking around 55 seconds.
According to SQLite documentation , inserting 1 records in a
database
takes time around 2 to 3 seconds.
Am i missing something , or is the behaviour correct?
Thanks,
Alok

Re: [android-developers] Re: Database insertion timings
Before the 1st insert call i am doing
db.beginTransaction();
for(i = 0 i 2000 ; i++)
addAlbumDB();
for(i = 0 i 3000 ; i++)
addArtistDB();
for(i = 0 i 2000 ; i++)
addSongDB();
try {
db.setTransactionSuccessful();
} finally {
db.endTransaction();
}

Anyways transaction should only be used if you have multiple actions
you are doing on your database (like several insert/update
operations)...

On an IPhone , its taking 1 or 2 seconds..
Here is an example of what i am doing..
private Boolean addAlbumDB(int AlbumId, String Name, String Label,
int MultipleArtists, int ArtistId) {
long result = -1;
try {
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_ID, AlbumId);

} catch (Exception e) {

return false;
}
if (result == -1)
return false;
return true;
}
The above function is called for around 2000 times..
Similarly there are 2 3 more functions for other tables.
Thanks,
Alok.

Each of these above functions insert records in 3 seperate tables in the
same database.
