 i want to handle exceptions in Service.
my exception handler sends error report email.
so i add FLAG_ACTIVITY_NEW_TASK flag and it works fine in onCreate().
but in UncaughtExceptionHandler, it doesn't send email.

so how it can send email in uncaughtException()?

public class ErrorReporter implements Thread.UncaughtExceptionHandler
  public void uncaughtException(Thread t, Throwable e) {
    // ...
    SendErrorMail(this.CurContext, Report);

  private void SendErrorMail(Context _context, String ErrorContent) {
        Intent sendIntent = new Intent(Intent.ACTION_SEND);
        String subject = ("Crash Report - Android ErrorReporter");
        String body = ErrorContent + "\n\n";
        sendIntent.putExtra(Intent.EXTRA_EMAIL, new String[]
        sendIntent.putExtra(Intent.EXTRA_TEXT, body);
        sendIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
        Intent i = Intent.createChooser(sendIntent, "Title:");
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  // because
Service ...

thank you

 First off, are you sure that your UncaughtExceptionHandler is not
throwing an exception?

 You email is not getting sent because you are not doing anything with
your sendIntent. You create it but then never use it.

 Scratch that. My mistake. I missed the Intent.createChooser line.
Have you taken a look at: 

I don't see any immediate errors in your code.

 thank you for your reply
I added try/catch code but I got no exception
and it still doesn't send a email ;(

            Log.d(LOG_TAG, "startActivity() called");
        } catch (Exception e)

below is my logcat log

 Here's your error:

java.lang.NullPointerException at
com.my.service.onCreate(ISPService.java line:230)

Take a look at line 230 of ISPService.java and try and see what could
possibly be null.

1. Is it possible to upgrade HTC Magic G2 from 1.5-Cupcake to 1.6-Donut ?

At some point, when 1.6 is finished, the update will be pushed to your
phone and it will ask you if you want to update.

Otherwise I think you can either flash your phone or apply the update


2. Mediastore Thumbnails not generated until Gallery app is launched ?

Is that normal that Images indexed in the MediaStore do not have
thumbnails generated until the Gallery app is launched and the user
actively navigates to the bucket where the image is stored ?

I think it's quite odd as I thought thulbnails generation was part of
media indexing.
