onGetViewFactory not called after onUpdate

I'm having trouble setting up a widget to my app, whenever I try to add a widget to my home screen onReceive is being called and right after that onUpdate is being called - but after onUpdate finishes - my custom RemoteViewsService is not called at all...
NotesWidgetProvider.class
public class NotesWidgetProvider extends AppWidgetProvider {
#Override

for (int appWidgetId : appWidgetIds) {

views.setRemoteAdapter(R.id.widget_notes, intent);
Intent clickIntent = new Intent(context, NoteActivity.class);
PendingIntent clickPendingIntentTemplate = TaskStackBuilder.create(context)
.addNextIntentWithParentStack(clickIntent)
.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.widget_notes, clickPendingIntentTemplate);
appWidgetManager.notifyAppWidgetViewDataChanged(appWidgetId, R.id.widget_notes);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
#Override

What am I missing? Can someone help figure it out?
UPDATE
I figured out that the problem was that I used AppCompat.ImageButton instead of ImageButton, now onGetViewFactory is called - but when reaching onGetViewFactory the widget changes to "Problem loading widget".

It might be too late to answer, but I think your issue come from your notes_widget_info.xml, change it to the following:
<?xml version="1.0" encoding="utf-8"?>

Android - Appwidget with Remoteviews not updating after reboot

I saw similar questions here on SO, but nothing seems to work in my case...
I created an appwidget with an AdapterViewFlipper (Simple ViewAnimator that will animate between two or more views that have been added to it). The appwidget has a Next button that enables the user to navigate to the next view on the widget.
It all works fine when I first add the appwidget. But if the smartphone reboots, the Next button of the widget no longer works on my Samsung S4 (the method onReceive is called, but nothings happens, it doesn't navigate to the next view and is stuck at the first view). I have to delete the widget and add it again in order for it to work...
I suspect that it is a problem of Touchwiz since I tested it on another phone (Moto G) and it worked fine.
Here are some portions of my code :
AppWidgetProvider
public class AppWidgetProvider extends AppWidgetProvider {
public static final String NEXT_ACTION = VersionUtil.getPackageName() + ".action.NEXT";
private static final String TAG = DailyAppWidget.class.getSimpleName();

Any help would be appreciated !

Depends on the launcher, there is no guarantee that your AppWidget will be updated immediately after the device started. It may be refreshed immeidately, or wait till the updatePeriodMillis passed after system started.
To solve your problem, define a BroadcastReceiver that will trigger the update of AppWidget after the reboot.
In AndroidManifest.xml, define the BootReceiver to get the boot_complete message.
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver android:name=".BootReceiver" android:enabled="true" android:exported="false" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
And define the BootReceiver.java to start your AppWidgetUpdateService
public class BootReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent){
//start appwidget update service
}
}

My android widget service stops after some time

I have an issue with my clock widget. I run a Service to refresh it when needed (on USER_PRESENT event and each minute while screen on), but this Service seems to be killed after some time, randomly, and is not restarted.
I have set notifications in my Service's onDestroy() and onLowMemory() methods but they are never called.
I never call the stopSelf() method.
The widget is no longer visible in launched application list into the system.
When the WidgetProvider naturally updates (every 6 hours), the service is restarted and all works perfectly for a moment.
Here is my code :
(note that the Application in the manifest is not named nor created in the code. Only the provider and service. don't know if it's correct)
Widget Provider :
public class WidgetProvider extends AppWidgetProvider {
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] ids) {
super.onUpdate(context, appWidgetManager, ids);
Intent serviceIntent = new Intent(context.getApplicationContext(), WidgetService.class);
context.startService(serviceIntent);
}
#Override
public void onDeleted(Context context, int[] appWidgetIds) {
super.onDeleted(context, appWidgetIds);
}
#Override
public void onDisabled(Context context) {
Intent serviceIntent = new Intent(context.getApplicationContext(), WidgetService.class);
context.stopService(serviceIntent);
super.onDisabled(context);
}
}
The Service :
public class WidgetService extends Service {
private static String LOG = WidgetService.class.getSimpleName();
public Hashtable<Integer, ClockView> views = new Hashtable<Integer, ClockView>();
AppWidgetManager man;
private static WidgetService self;
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
Toast.makeText(this, LOG+" configuration change", Toast.LENGTH_LONG).show();
}
#Override
public void onCreate() {
super.onCreate();
man = AppWidgetManager.getInstance(this);
self = this;
// Registering Intent for screen state
...
registerReceiver(screenoffReceiver, filter);
// Registering Intent for click event
...
UpdateAllWidgets();
}

Widget onclick not working with configuraion activity

When I click a button in a widget, a Toast appears. But when I use a configuration activit to set the button's caption and then I click the button, the Toast doesn't appear. Why?
public class MyWidget extends AppWidgetProvider {
public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget";
public static String ACTION_WIDGET_RECEIVER = "ActionReceiverWidget";
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
Intent intent = new Intent(context, MyWidget.class);
intent.setAction(ACTION_WIDGET_RECEIVER);
PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
remoteViews.setOnClickPendingIntent(R.id.btn_widget, actionPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews); //update our widget
}
#Override
public void onDeleted(Context context, int[] appWidgetIds) {
super.onDeleted(context, appWidgetIds);
}
#Override
public void onDisabled(Context context) {
super.onDisabled(context);
}
#Override
public void onEnabled(Context context) {
super.onEnabled(context);
}
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_WIDGET_RECEIVER))
{
Toast.makeText(context, "You have just clicked the button!", Toast.LENGTH_LONG).show();
}
super.onReceive(context, intent);
}
Appwidget-provider xml:
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider

Configuration Activity:
public class ConfigActivity extends Activity {
Button btn;
EditText et;
Context c;
AppWidgetManager awm;
int awID;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.config);
btn = (Button)findViewById(R.id.btn);
et = (EditText)findViewById(R.id.et);
c = ConfigActivity.this;
//Getting info about the widget that launched this Activity
Intent i = getIntent();
Bundle extras = i.getExtras();
if (extras != null)
{
awID = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
}
else
{
finish();
}
awm = AppWidgetManager.getInstance(c);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String newcaption = et.getText().toString();
RemoteViews views = new RemoteViews(c.getPackageName(), R.layout.widget_layout);
views.setTextViewText(R.id.btn_widget, newcaption);
views.setTextColor(R.id.btn_widget, Color.RED);
awm.updateAppWidget(awID, views);
Intent result = new Intent();
result.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, awID);
setResult(RESULT_OK, result);
finish();
}
});
}
}
If I remove the line android:configure="com.bfarago.tutorials.widget.ConfigActivity" from the appwidgetprovider xml, I see the Toast.

Your configure Activity's onClick calls updateAppWidget without having called setOnClickPendingIntent on the RemoteViews it passes in, so once it has run, there will be no click event from your widget. Fix it to be the same as your onUpdate method, or better yet, refactor the code so there's only one function that creates the RemoteViews and calls updateAppWidget.
