Permission Denial Error - SpeechRecognizer as a continuous service? (android.permission.INTERACT_ACROSS_USERS_FULL)

Question

EDITED: I have changed my service code to implement as started service instead of IntentService as updated StreamService.java below Now, I am getting error regarding permission denial error as described in logcat messages after StreamService.java

EDITED:

As mentioned in Android Developer site that SpeechRecognizer API can only be used as Application Context. Is there any woraround with which I can get it working

I have implemented MainActivity class that has all the UI Components. Class is as below

CODE - MainActivity.java

package com.example.speechsensorservice;

import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.ImageButton;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {


    private static final String TAG = "SpeechSensor";

    private boolean headsetConnected = false;

    public TextView txtText;

    private BroadcastReceiver mReceiver;
    private ImageButton btnSpeak;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        txtText = (TextView) findViewById(R.id.txtText);
        btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);

        btnSpeak.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getApplicationContext(),StreamService.class);
                startService(intent);
            }
        });
    }

    protected void onResume() {
        super.onResume();

        IntentFilter sIF = new IntentFilter();
        sIF.addAction(Intent.ACTION_HEADSET_PLUG);
        sIF.addAction("com.example.speechsensorservice.TEXT");
        mReceiver = new BroadcastReceiver() {

                @Override
            public void onReceive(Context arg0, Intent arg1) {
                // TODO Auto-generated method stub
                String act = arg1.getAction();
                Log.d(TAG, "Received Action = " + act);
                if ( Intent.ACTION_HEADSET_PLUG.equals(act) ) {
                    if ( arg1.hasExtra("state")) {
                        if ( !headsetConnected && arg1.getIntExtra("state", 0) == 1 ) {
                            headsetConnected = true;
                            txtText.setText("Headset Plugged in");
                            startNoiseProcessService();
                        }
                    }
                }
                else if ( act.equals("com.example.speechsensorservice.TEXT") ){
                    if ( arg1.hasExtra("Identity")) {
                        String s = arg1.getStringExtra("Identity");
                        if ( s.equals("NA") ) {
                            Toast t = Toast.makeText(getApplicationContext(), 
                                    "Your Device doesnot support Speech to Text", 
                                    Toast.LENGTH_SHORT);
                            t.show();
                        }
                        else txtText.setText(s);
                    }
                }
            }

        };  

        this.registerReceiver(mReceiver, sIF);      
    }

    public void onPause() {
        super.onPause();
        this.unregisterReceiver(this.mReceiver);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
       getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    public void startNoiseProcessService() {
        Intent intent = new Intent(this,StreamService.class);
        startService(intent);
    }


}

Another class that I have implemented to start Speech Recognition Service as a background task by inheriting IntentService class. The implementation is as below

Code - StreamService.java

    package com.example.speechsensorservice;

import java.util.ArrayList;

import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

import android.os.IBinder;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.util.Log;

public class StreamService extends Service {
     private static final String TAG = "SpeechSensor";
     private static final String ACTION = "com.example.speechsensorservice.TEXT";
    private SpeechRecognizer sr;

    private BroadcastReceiver sReceiver;

    private boolean headsetConnected = true;

    String text;


    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onCreate() {
        Log.d(TAG, "onCreate() StreamService Method");
        super.onCreate();
        sReceiver = new BroadcastReceiver() {
            public void onReceive(Context arg0, Intent arg1) {
                // TODO Auto-generated method stub
                if ( Intent.ACTION_HEADSET_PLUG.equals(arg1.getAction()) ) {
                    if ( arg1.hasExtra("state")) {
                            if ( headsetConnected && arg1.getIntExtra("state", 0) == 0 ) {
                                headsetConnected = false;
                                stopStreaming(); 
                            } 
                    }
                }
            }

        };  
        this.registerReceiver(sReceiver, new IntentFilter(Intent.ACTION_HEADSET_PLUG)); 
    }

    @Override

        Log.d(TAG,"Inside onStartCommand()");

        return Service.START_STICKY;

    }

    @Override
    public  void onDestroy() {
        Log.d(TAG, "onDestroy() StreamService Method");
        super.onDestroy();

                sr.setRecognitionListener( new mylistener());

        }

}

Here I am getting error java.lang.RuntimeException: SpeechRecognizer should be used only from the application's main thread

Code flow is like this:

ImageButton->onClick()->Fire the service Intent for StreamService.class->onCreate()->onHandleIntent()->calling startStreaming() -> getting error

[IntentService#onHandleIntent()](http://developer.android.com/reference/android/app/IntentService.html#onHandleIntent%28android.content.Intent%29) documentation says "worker thread". Use a regular service and override `onStartCommand` — zapl, Dec 13 '13 at 09:34
Still, not working. Is there is any way by which I can run the speechrecognizer instance with the Main thread Context. i.e. UI thread — Aki008, Dec 13 '13 at 10:00
All methods of a `Service` besides `onHandleIntent` in `IntentService` are executed within the main thread. — zapl, Dec 13 '13 at 10:01

Sorry, but it is still asking for (android.permission.INTERACT_ACROSS_USERS_FULL) — Aki008, Dec 17 '13 at 03:42

There are times when this particular error is actually misleading, and is caused by other runtime problems.

I documented one such example here - a NullPointerException thrown down deep ended up being reported as this same error, even though it had nothing to do with cross-user permissions.

In my particular case, ProGuard was stripping out a method that I needed, which caused a NullPointerException to be thrown. The stack trace looked like this:

Permission Denial: get/set setting for user asks to run as user -2 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL

 at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1003)
 at dalvik.system.NativeStart.main(Native Method)

I haven't a clue in the world why Android turned the NullPointerException into the android.permission.INTERACT_ACROSS_USERS_FULL error, but the obvious solution was to tweak the ProGuard configuration so that the method wasn't being stripped.

The method I was calling that wasn't there was the "valueOf" method on an enum. It turns out that there's some interesting reflection involved under the hood (which I go into at the link above), but the solution for me was to add the following to my ProGuard configuration.

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

Note that [link-only answers](http://meta.stackoverflow.com/tags/link-only-answers/info) are discouraged, SO answers should be the end-point of a search for a solution (vs. yet another stopover of references, which tend to get stale over time). Please consider adding a stand-alone synopsis here, keeping the link as a reference. — kleopatra, Apr 16 '14 at 16:57

well the problem is self solution explaining , the first line in your logCat is giving you the solution that, the current thread does not have the permission for executing user task , so just add the following permission in manifest and see if it works out .

<uses-permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL">

lemme know if I had understood the problem correctly

This permission is a signature level permission and we can only use it when the signature of my app will be same as the system. – Aki008 Dec 13 '13 at 11:51

And as explained here: http://stackoverflow.com/a/19756762/642160 -- that's not something that's feasible for a typical app developer. – benkc Feb 10 '14 at 20:15
