Someone requested the changes that fixed this issue so here they are:
public class MyReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
try
{
Intent iAlarm = new Intent( context,
MyActivity.class );
iAlarm.addFlags(Intent.FLAG_FROM_BACKGROUND);
iAlarm.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); //
Added
iAlarm.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(iAlarm);
}
catch( Exception e )
{
.....
}
}
}
Then in my manifest:
To the activity tag: android:launchMode="singleTask"
Seems to work like a charm now!
