I have an AppWidget with 2 pending intents. They work most of the time, but after a while they stop responding. Only thing I have been able to pinpoint is that they are crippled after a Launcher restart, i.e. I use Launcher Pro, and sometimes fiddle with settings and have to restart it. After that they don't work at all.
Here are my onRecieve()
and onUpdate()
methods:
public void onReceive(Context context, Intent intent)
{
super.o开发者_运维技巧nReceive(context, intent);
String action = intent.getAction();
if(action.equals("android.tristan.widget.digiclock.CLICK"))
{
PackageManager packageManager = context.getPackageManager();
Intent alarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER);
String clockImpls[][] = {
{"HTC Alarm Clock", "com.htc.android.worldclock", "com.htc.android.worldclock.AlarmClock" },
{"Standar Alarm Clock", "com.android.deskclock", "com.android.deskclock.AlarmClock"},
{"Froyo Nexus Alarm Clock", "com.google.android.deskclock", "com.android.deskclock.DeskClock"},
{"Moto Blur Alarm Clock", "com.motorola.blur.alarmclock", "com.motorola.blur.alarmclock.AlarmClock"}
};
boolean foundClockImpl = false;
for(int i=0; i<clockImpls.length; i++) {
String vendor = clockImpls[i][0];
String packageName = clockImpls[i][1];
String className = clockImpls[i][2];
try {
ComponentName cn = new ComponentName(packageName, className);
ActivityInfo aInfo = packageManager.getActivityInfo(cn, PackageManager.GET_META_DATA);
alarmClockIntent.setComponent(cn);
foundClockImpl = true;
} catch (NameNotFoundException e) {
Log.d(LOGTAG, "Error," + vendor + " does not exist");
}
}
if (foundClockImpl) {
Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(50);
final RemoteViews views = new RemoteViews(context.getPackageName(), layoutID);
views.setOnClickPendingIntent(R.id.TopRow, PendingIntent.getActivity(context, 0, new Intent(context, DigiClock.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK), PendingIntent.FLAG_UPDATE_CURRENT));
AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);
alarmClockIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(alarmClockIntent);
}
}
}
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
context.startService(new Intent(UpdateService.ACTION_UPDATE));
context.startService(new Intent(context, ScreenUpdateService.class));
final int Top = appWidgetIds.length;
final int Bottom = appWidgetIds.length;
for (int i=0; i<Top; i++)
{
int[] appWidgetId = appWidgetIds;
final RemoteViews top=new RemoteViews(context.getPackageName(), layoutID);
Intent clickintent=new Intent("android.tristan.widget.digiclock.CLICK");
PendingIntent pendingIntentClick=PendingIntent.getBroadcast(context, 0, clickintent, 0);
top.setOnClickPendingIntent(R.id.TopRow, pendingIntentClick);
appWidgetManager.updateAppWidget(appWidgetId, top);
}
for (int i=0; i<Bottom; i++)
{
int[] appWidgetId = appWidgetIds;
RemoteViews bottom=new RemoteViews(context.getPackageName(), layoutID);
Intent clickintent=new Intent("android.tristan.widget.digiclock.CLICK_2");
PendingIntent pendingIntentClick=PendingIntent.getBroadcast(context, 0, clickintent, 0);
bottom.setOnClickPendingIntent(R.id.BottomRow, pendingIntentClick);
appWidgetManager.updateAppWidget(appWidgetId, bottom);
}
}
I have read about putting the intents in a service, but have tried and failed. Any help is appreciated.
As I've written here you should only produce a single instance of the RemoteView.
PendingIntent.getBroadcast
has an argument called requestCode
, it must be a unique code in case of multiple PendingIntent
.
you've set it to 0 for all of your PendingIntents
.
