I want to set a global uncaught exception handler for all the threads in my Android application. So, in my Application subclass I set an implementation of Thread.UncaughtExceptionHandler as default handler for uncaught exceptions...

I'm trying to do a simple global exception handler in my Android app and I am having troubles:
public class TicTacToe extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Thread.currentThread().setUncaughtExceptionHandler(new UncaughtExceptionHandler() {
@Override
public void uncaughtException(Thread thread, Throwable ex) {
Toast.makeText(this, "TOAST", Toast.LENGTH_LONG);
} } );
setContentView(R.layout.main);
} }
I'm a rather new with both Android and Java but in .NET that would work. Can't I access local variable from anonymous methods in Java? If so, how should I rewrite it?
I am trying to get the selected item of my spinner that is populated and I am already seeing the values. when I try to use (String) s.getSelectedItem(); to get the selected item, I am receiving a handler exception on Logcat.
The spinner throwing the error is a 2nd spinner resulting from the 1st spinner's selected item (that works perfectly). In other words, user selects from spinner one and upon selection, populates spinner 2 (until here everything is fine). When trying to get the value of the selected row in spinner2 , I am receiving the error.
here's the main parts of my code...
I am trying to enable global search for messaging application (i.e., messages can be searched from home screen search box). I have followed all the steps given in http://developer.android.com/reference/android/app/SearchManager.html

Whenever I run above code I get NullPointer Exception .Please help me to update the view.
I love the feature where we can inspect any exceptions for app's published on the market through the developer site but curious as to whether we can tap into this feature for app's we don't publish to the market so we can email any exception details to a specific email address for example.

I created a sql lite database with the following columns:
static final String dbName="demoDB";

I want to select all the records in the database like this and display them in a gridview:SQLiteDatabase db=this.getWritableDatabase();Cursor cur= db.rawQuery("Select "+colName+", "+colAge+" from "+tableName, new String [] {});String [] from=new String []{DatabaseHelper.colName,DatabaseHelper.colAge};

I'm currently working on Android NDK, porting my libs, and I'm using SWIG (Simplified Wrapper and Interface Generator) that is a great tool to generate JNI code around my C/C++ headers for Java.
However, there is a big issue using it on Android, 'cause of incomplete JNI support : 'Weak Global References' are missing. Unfortunatly, SWIG is waiting for a full compatible Oracle/Sun JVM, and use this feature with its 'director' option (for proxy class creation).
For now, I comment each time, in a (kind of) bad way, the use of weak global references in my generated C/C++ wrapper files (4 lines in my case). I think it is really a shame that we can't use (one of) the best wrapper with Android NDK just for one missing feature.
I read that Google Team will add it in future release : "NewWeakGlobalRef and DeleteWeakGlobalRef are not implemented. The VM supports weak references, but not JNI "weak global" references. These will be supported in a future release." (http://android.git.kernel.org/?p=platform/ dalvik.git;a=blob_plain;f=docs/jni-tips.html;hb=HEAD)
So my question is, does anybody know when 'Weak Global References' will appear in Android NDK ?
Let's say I want all the TextView instances in my app to have textColor="#ffffff". Is there a way to set that in one place instead of setting it for each TextView?

But here i am facing one problem that is it is running after closing my application also .
please solve my problem to stop this handler when close this application.
After much deliberation, hopefully next Friday I will be ordering the Droid 2 Global. This will be my first SmartPhone and Android device. For those who have the White model, does it stain easily? Would the hard clear case Verizon sells cause any friction on the painted surface, particularly the corners, to wear or chip?

I know how to create a menu in my application with an icon and text on each "button" of the menu, but this menu is only visible on the activity where I created it...
I would like to know if it is possible to create a global menu which would be accessible from all activities?
I was wondering if it is possible to intercept keyboard input on a global level on Android. For example a user types in text into an edittext (does not matter which application) I would like to access said text to check for certain words. Is this even possible with Android's security model (yes I am aware this kind of feature could be used for various wrong things too).

View 6 Replies View RelatedSince the Droid 2 Global is coming out soon. I think a Droid X Global (w/ the 1.2GHz CPU) will be the real killer here. Anyone thinks so, too? BTW, I have a Droid X and my daughter have the D2 (R2D2). I like the DX compared to the D2 and my upgrade plan is to get a global Droid phone. Hopefully, a Droid X Global is in the works.
View 4 Replies View RelatedIt looks like I am going to pull the trigger on a D2G assuming VZ will give me an early upgrade. I have not been able to get much info on the D2G yet so thought I would see if anyone could share their experience so far here. BTW - I am coming from a Storm2 so have high hopes. I will post my experience once I have the phone in a few days.
View 13 Replies View RelatedThe Droid 2 alone wasn't all that impressive to me. But the Droid 2 global looks like it could be pretty sweet. I'm liking the 1.2 ghz processor inside. I don't know if Ill need the global capabilities but it seems like a pretty good upgrade from the standard Droid 2. Just curious what your guys thought is on this? Don't get me wrong I love my Droid Incredible but I'm wondering if the Droid 2 global will be a little snapping with the better processor.

View 4 Replies View RelatedI know this is going to sound pretty lame but I have never had a need to send or receive a text message but now find that it might be useful. I have a Droid Global phone but I have no idea of how to text. I just want to be able to send and receive text messages from my grandkids.
View 5 Replies View RelatedI know you can create shortcuts to the main Settings menus (battery use, bluetooth settings, etc.) by just long-pressing the screen -> Shortcuts, but I need to create a shortcut to a submenu (specifically Settings -> Wireless & Networks -> Mobile Networks -> Network Mode) This is on a Droid 2 Global. Anyone know how I can do this? I have LauncherPro and I know you can make shortcuts with it but programming those shortcuts seems pretty complicated. Also I know you can make additional shortcuts using the LauncherPro "Activities" menu but I can't find the "Network Mode" settings in that list either.
View 6 Replies View RelatedI am having issues with my droid 2 global, bootloader is stuck at "MEM_MAP blank" which i can fix easily, but a really irritating issue is happening...
I am stuck at "Battery Low, Cannot Program". Now dont tell me that i need to charge it! ive had it plugged in for hours. usually it takes 1 hour to get 0% to 100% battery. i was inatlling the cyanogen mod and i did exactly what it said, but it said "Pull out the battery and press "X" and power back" or something like that. so i just got mad and left the device alone, then when i turned the device back on, i got "MEM_MAP blank". No problem. but then i noticed it flashing that i needed to charge it,, several hours later of charging. still have low battery, ive tried to boot into recovery, no luck, i have a external dock if that information is useful, i dont need support on the mem map, just this charging issue.
I just learned how to do this from a fellow Forum member and wanted to post it up here in case other do a "search" for this. Very few are aware you can do this, or that Droid/Eris allow you to do it at all.Open Exchange email client

Assuming I didn't start in debug mode, is there a way to make the eclipse debugger automatically start if my app throws an exception inside the emulator?
Alternatively, is there a way to get a more useful error message out of the emulator (something more useful than "Sorry, your app terminated unexpectedly").
I am working on an application wich has its own URI prefix. (dchub:// in this case) is there a way when someone open his browser, clicks on a link starting with dchub:// my app starts using this address? so far found a lot of examples the otherway around opening the browser from your app but thats not what i'm looking for.
