Use Environment.getExternalStorageState() and the ACTION_MEDIA_ broadcast Intents to monitor when external storage is available.

[android-developers] Re: Socket freezes using GSM connection
Kostya,
I've changed the reading as you suggested and I haven't found any
significant improvement although I do think that you proposal is a
better programing to avoid problems like connection problem which
cause missing packets.
I didn't understand if your implementation with NIO give you better
notification when there is a problem with the socket connection.
my problem is that the socket thinks that it is connected and no
exception being thrown even if it was disconnected due to poor network
signal.
how can I detect this on time and open a fresh one?
I'm still trying to figure out how can I use Broadcast intents for the
data connection state - maybe this will help.

Ayanir,
NIO is non-blocking, so it's easier to serve multiple connections from
one thread. Also, NIO is easier to interrupt / shutdown, which I think
is important for an Android app. But other than that, I personally think
it's a matter of taste, since there has to be a worker thread for both
NIO and old style.
In the code you posted, DataOutputStream should write the entire data
structure, blocking until it does. So with the change on the reading
side (looking for '\0' anywhere) it _should_ already work - have you
tested it yet?

Ayanir,
Your code seems to make assumptions about network data exchange that
don't necessarily hold true for GSM connection, such as:
- write() always sending the entire data buffer, this may not be the
case. It's necessary to check the return value to see how much was
actually sent.
- read() receiving data broken down by the same chunks as were sent. The
check for '\0' needs to be changed to look for it anywhere in the
buffer, breaking it down into application-specific packets.

Does anyone encounter connection stability problems?
Do I need to open the connection differently?
How about using SocketChannel is it more reliable?

[android-developers] how can I get the Google account or Gmail address from the phone
Hello, I was looking for this info all over and still haven't found an answer.

[android-developers] Re: how can I get the Google account or Gmail address from the phone
I think I found it.
the original post is from:
http://groups.google.com/group/android-developers/browse_thread/thread/7a6bf77910ca31e0/7a7659d61a89fa41?lnk=gstq=how+can+I+get+the+Google+account+or+Gmail+address+from+the+phone#7a7659d61a89fa41
1. download the framework.jar from:
http://github.com/android/platform_frameworks_opt_com.google.android/blob/7e12826d58454d3bade238e3b2c43fe402278f19/framework.jar
and add it to you build path. this is some sort of an interface to the
Google device functions.
2. call the method:
com.google.android.googlelogin.GoogleLoginServiceHelper.getAccount(Activity
activity, int requestCode, boolean requireGoogle);
where:
Activity: is your Activity which get the result in the
onActivityResult()
requestCode: your code
requireGoogle: should be true
EX. GoogleLoginServiceHelper.getAccount(mActivity, 123, true);
3. override the onActivityResult() like:
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 123){
System.out.println(resultCode);
String key = accounts;
System.out.println(key + : +
Arrays.toString(data.getExtras().getStringArray(key)));
String accounts[] = data.getExtras().getStringArray(key);
if(accounts != null){
int i = 0;
for(String ac : accounts){ //each account is the full
email address registered with this device
System.out.println(ac + i + = + ac);
i++;
}
}
}
4. add in the AndroidManifest.xml the following permition:
uses-permission
android:name=com.google.android.googleapps.permission.GOOGLE_AUTH/
uses-permission
5. your done!
enjoy

[android-developers] Socket freezes via GSM connection
Hello,

I’ve implemented 2 different Threads for the read() and the write()

being thrown. It means that there are freezes – the write and read
seems to work but no data is actually being piped.

[android-developers] Re: Launching the correct activity on resume
thanks jotobjects, I wanted to add few comments: 1.when I used the singleTask in launchMode, when I opened the app icon from the Home screen, it stated Activity A and not the last Activity. so this is not the solution. 2.from: http://developer.android.com/intl/de/guide/topics/manifest/activity-element.html I understand that I actually need to use singleTop since: The standard and singleTop modes differ from each other in just one respect: Every time there's new intent for a standard activity, a new instance of the class is created to respond to that intent. Each instance handles a single intent. Similarly, a new instance of a singleTop activity may also be created to handle a new intent. However, if the target task already has an existing instance of the activity at the top of its stack, that instance will receive the new intent (in an onNewIntent() call); a new instance is not created. using singleTop did solve the open from Home screen icon behavior but it still didn't fixed the open from Market behavior. again, I'm trying getting the application to always open from the last Activity no mater how it is opened. does anyone has any other thought on how to solve this? ayanir On Jan 27, 9:34 pm, jotobjects jotobje...@gmail.com wrote: On Jan 27, 2:13 am, ayanir ayanir...@gmail.com wrote: Hello, I have a similar problem when I open the application from the Market. if I go from Activity A (LAUNCHER) to B, press Home key and re open the application from the Home screen icon it come back to Activity B (the last Activity) as it should. but, if I open the application from the Market application, it open Activity A. what is the difference between these two Not sure exactly about the difference, but the general point is that the Home Screen launcher is keeping track of the Task that was launched from the Home screen for that app and will resume that same task with the Activity that is on top of that task. This only applies to launching from the Home screen. and how can it always open from the last Activity no mater how I open the application?

In the interests of clearing up quite a bit of misinformation in this thread, this is the what actually happens: Re-launching the Activity from the Home screen returns to the same Task that initially started that Activity (the one where action=MAIN and category=LAUNCHER). But whatever Activity was on top of that old Task is again the foreground Activity (unless clearTaskOnLaunch is set). The Activity listed in the Manifest with category LAUNCHER is NOT the Activity that is active and setting singleTop is not necessary to get this standard behavior.

I've tried some of the suggestions posted here and it seems like the main thing that was stopping me was not doing a full .apk build prior to each test. I implemented the android:launchMode=singleTop manifest flag, but that didn't actually seem to get me my desired functionality. The only time I ever hit the onNewIntent() execution block was if I hit home from Activity1 and relaunched. Hitting home from Activity2 simply resulted in returning to Activity1 on relaunch.

[android-developers] Re: Launching the correct activity on resume
Hello, I have a similar problem when I open the application from the Market. if I go from Activity A (LAUNCHER) to B, press Home key and re open the application from the Home screen icon it come back to Activity B (the last Activity) as it should. but, if I open the application from the Market application, it open Activity A. what is the difference between these two and how can it always open from the last Activity no mater how I open the application?

In the interests of clearing up quite a bit of misinformation in this thread, this is the what actually happens: Re-launching the Activity from the Home screen returns to the same Task that initially started that Activity (the one where action=MAIN and category=LAUNCHER). But whatever Activity was on top of that old Task is again the foreground Activity (unless clearTaskOnLaunch is set). The Activity listed in the Manifest with category LAUNCHER is NOT the Activity that is active and setting singleTop is not necessary to get this standard behavior.

[android-developers] Run application from last Activity/state
Hello, I have an application with several Activities. My A Activity has the Manifest Intent filter parameters: action.MAIN and category.LAUNCHER. after its being loaded I call Activity B and finish() A since I don't use it anymore. After I run my application, go from Activity A to B and press the Home button, when I relaunch it from the applications menu or from the Market app for ex.(not by a long press on the Home button), it starts from the A Activity and do not save its last Activity B. I definitely know that this is possible to relaunch an application from its last Activity (some application from the Market do support it) and I think that this can be determined by the Manifest parameters but I don't know which one. does anyone know how to implement it so my application can relaunch from its last Activity B?

[android-developers] Re: SoundPool problem
It is very annoying that this problem stared with the 2.0 version
(hope that the framework developers see that remark) while in the 1.6
and 1.5 it worked fine.
The workaround for this problem, besides of changing the files format
is using MediaPlayer and handle the sound low level (which I really
don't want to do).
BTW, my all sounds are not even close to the 1 MB limit so the problem
is not that.
Nikolay, I didn't understand, did you have to encode the sound to mono
for all of the souds or just for the long one(7 sec)?

[android-developers] end application notification
Hello, I have an application with several Activities. I understand that the Android platform handle some sort of an Activity Stack so there is the option to go back to the previous Activities in the stack. I also know that there is no access to this Stack. I would like to know if there is a way to check if all my application Activities are finished (not in the Stack). in other words, if I'm in my first Activity and press the Back key or alternatively call Activity.finish(), I would like to get a notification that all my Application Activities are finished so I can control my application exit.

[android-developers] Re: Relative Layout XML attributes have no obvious programmatic equivalent.
Hello again,
I just wanted to add that the layout.xml:
RelativeLayout
xmlns:android=http://schemas.android.com/apk/res/android;
android:layout_width=wrap_content
android:layout_height=wrap_content
com.example.RPCPlayerInfoTitle
android:id=@+id/player_info
android:layout_width=wrap_content
android:layout_height=wrap_content /
/RelativeLayout
when I changed the layout_width and layout_height to constants, the
addRule works.
another thing I've noticed is that when I don't override onMeasure in
RPCPlayerInfoTitle, myImage is being aligned to the bottom of the
screen. from some strange reason myImage doesn't recognized
RPCPlayerInfoTitle (my custom View) as its parent or ignore its
dimensions.

[android-developers] Re: SurfaceViews handling, Thread, and general game design
Hello Dianne , Thank you for you response. according to your words, I do not need that each Box will be as a Surface view but only one game surface view and the only way I can mange the game objects(Boxes etc.) is by using a low level management of drawing and event handling. If I trying to answer my own question then option (4) is the way to do it. I thought I will design my game Flash style where each object draw itself and the main Activity will handle the events and drawing Threads but I presume we are not there yet. It helped me a lot to read Playing with graphics in Android Tutorial (http://www.droidnova.com/playing-with-graphics-in-android- part-i,147.html) which spread a light on hot to use surface view and animation. Regards to you all ayanir On Jul 14, 7:06 pm, Dianne Hackborn hack...@android.com wrote: I very strongly recommend that you don't use multiple surface views. A surface view is a very heavy-weight object, and intended for the primary area of the window -- for example, the video part of a video player, the playfield of a game, etc. It is basically an overlay, and actually its own separate full window that is simply being Z-ordered with your main window to make it look like they are related. I don't know what your complicated animation sequence is, but just having some animation is not enough reason to use a surface view. Worst case, you can just create an off-screen bitmap that you draw the animation in and update the screen by drawing that bitmap to the screen with the normal invalidate() mechanism. If you need the performance of a surface view, then you should design your game so that your entire playfield is on surface view, and you take care of drawing each of your boxes inside of that and manage them however you want (not as their own views). On Tue, Jul 14, 2009 at 4:27 AM, ayanir ayanir...@gmail.com wrote: Hello, I'm a new Android developer. I would like to make a simple game using the SurfaceView (Canvas drawing). the game has a a custom Object name Box. Box can draw itself and need to get an event when it is clicked. when it does, there is an animation sequence coming out of the box like a jumping clown. I have several Boxes on the screen when each of them can be activated. Several Boxes animation can also be presented simultaneously. Here it gets tricky: Since I have a complicated animation sequence, each Box extends SurfaceView. The problem is I haven't figured it out how can I handle several SurfaceView's drawing using only one Thread (in order to present an animation I need to use one) and also how can I get the onClick/ onThouch event from my Activity to each of my Boxes. The LunarLanding example in the SDK uses only one Thread but also uses only one SurfaceView which manage the animation of the game components (there are no several game components SurfaceViews). Also, there is no need to get onTouch event, so this example doesn't match to my case. I have several questions about what is the right approach do code this: 1. Should I use Box extends SurfaceView? 2. Can SurfaceView gets user events like onTouch/onClick? 3. Is there a way to add to the main SurfaceView another SurfaceView (Box)? 4. If none of the above questions is positive, should I use one SurfaceView (and one Thread) and try to map the other Boxes on the screen for user event handling. I mean Box only paints itself but the user event is being handled by me (not by the OS). 5.

[android-developers] Re: SurfaceViews handling, Thread, and general game design
Here is the correct link: http://www.droidnova.com/playing-with-graphics-in-android-part-i,147.html On Jul 15, 2:33 pm, ayanir ayanir...@gmail.com wrote: Hello Dianne , Thank you for you response. according to your words, I do not need that each Box will be as a Surface view but only one game surface view and the only way I can mange the game objects(Boxes etc.) is by using a low level management of drawing and event handling. If I trying to answer my own question then option (4) is the way to do it. I thought I will design my game Flash style where each object draw itself and the main Activity will handle the events and drawing Threads but I presume we are not there yet. It helped me a lot to read Playing with graphics in Android Tutorial (http://www.droidnova.com/playing-with-graphics-in-android- part-i,147.html) which spread a light on hot to use surface view and animation. Regards to you all ayanir On Jul 14, 7:06 pm, Dianne Hackborn hack...@android.com wrote: I very strongly recommend that you don't use multiple surface views. A surface view is a very heavy-weight object, and intended for the primary area of the window -- for example, the video part of a video player, the playfield of a game, etc. It is basically an overlay, and actually its own separate full window that is simply being Z-ordered with your main window to make it look like they are related. I don't know what your complicated animation sequence is, but just having some animation is not enough reason to use a surface view. Worst case, you can just create an off-screen bitmap that you draw the animation in and update the screen by drawing that bitmap to the screen with the normal invalidate() mechanism. If you need the performance of a surface view, then you should design your game so that your entire playfield is on surface view, and you take care of drawing each of your boxes inside of that and manage them however you want (not as their own views).

[android-developers] ListView with different types of View's
Hello for all the Android's out there, I'm trying to make a ListView when every item in that list can be a different type of View. for example the list could be: 1. TextView 2. ImageView 3. MyCustomView I understands that in order to make a list I need to use an Adapter. the problem is that the Adapter uses a single layout for all of the list items, which will not support the different views. my goal is to make an abstract View list when I can dynamically add and removes items in that list (each item is a View or subclass of it).
