Android Widget - Permission Denial

Navigation
3

I'm having a permission problem that has slipped a bit from my knowledge. Inside a widget I inserted a button, which when pressing I get the following message:

  

04-13 14: 10: 44.340: E / DatabaseUtils (2362): java.lang.SecurityException: Permission Denial: get / set setting for user asks to run user -2 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL

It works as follows: In the WidgetApp class, in the onUpdate () method I have the following lines ( lines in question ): 

rv = new RemoteViews(context.getPackageName(),R.layout.widget_layout);
Intent intentSync = new Intent(context, Sincroniza.class);
PendingIntent piS = PendingIntent.getActivity(context, 0, intentSync, 0);        
rv.setOnClickPendingIntent(R.id.widget_Btn_Atualiza, piS);

In Activity Sync I have the following lines in the onCreate () method: 

    this.runOnUiThread(new Runnable() {

        @Override
        public void run() {
            Intent intentService = new Intent(getApplicationContext(), AWidget.class);
            startService(intentService);

            Toast.makeText(getApplicationContext(), "Widget Atualizado!", Toast.LENGTH_LONG).show();

        }
    });


    finish();

That is, on the lines above: load Activity, make the service call and close. For those who work with Widget, you know that setOnClickPendingIntent () needs to be called a PendingIntent.

On the INTERACT_ACROSS_USERS_FULL permission, it's no use putting the uses permissions, which does not even stay on the standard sdk list, you have to enter manual. Secondly, that's no use.

In short, my widget (which is based on BroadcastReceiver by default for Android) loads a RemoteViews layout and inserts a desired button event (setOnClickPendingIntent). This event loads an Activity, which executes a Service, and then closes the same Activity.

INTERESTING: All this works normal for a period, after a few minutes to work.

DETAIL: The Service class AWidget.class uses in an AlarmManager and works without problems.

Hello, I've researched a bit and found several people with the same problem as yours asking for clarification in stackoverflow.com , where the best answer can be accessed here . It says the following:

android.permission.INTERACT_ACROSS_USERS_FULL is a signature level permission. Your application will not be able to use it before it has the same signature as the system.

This is not possible unless you are the creator of the system or get a certificate for your application.

In other words, that unfortunately is out of bounds for most developers.

Here are some other useful links:

I hope to have helped, any questions ask in the comments.
