location sendExtraCommands - Methode funktioniert nicht und schaltet die App herunter

Question

Ich versuche den gps-Chip meines Smartphones programmtechnisch mit der sendExtraCommand() - Methode zu löschen. In meinem Manifest-Datei habe ich die Erlaubnis zusätzliche Befehle wie folgt an:

<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"/>

Die Methode selbst nenne ich wie folgt aus:

locationManager.sendExtraCommand(LocationManager.GPS_PROVIDER, "delete_aiding_data", null)

Wenn ich es auf dem Emulator versuchen oder auf Mein Smartphone stürzt ab. Ich weiß nicht, was ich falsch mache, also würde ich es sehr schätzen, wenn sich jemand mein Problem ansehen könnte.

Meine einzige Aktivität, die MainActivity:

public class MainActivity extends AppCompatActivity { 

     private TextView textView; 
     private Button button; 
     private LocationManager locationManager; 

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

      textView = (TextView) findViewById(R.id.txtView1); 
      textView.setText("Gps Reset: "); 

      button = (Button) findViewById(R.id.button); 

      locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); 

      boolean enabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER); 
    System.out.println(enabled); 

      button.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View view) { 
        sendXtraCommand(); 
       } 
      }); 

     } 

     private void sendXtraCommand(){ 
      boolean reset = locationManager.sendExtraCommand(LocationManager.GPS_PROVIDER, "delete_aiding_data", null); 
      if(reset){ 
       textView.append("true"); 
      }else{ 
       textView.append("false"); 
      } 
     } 
    } 

Und hier meine Manifest-Datei:

<?xml version="1.0" encoding="utf-8"?> 
    <manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.example.felix.resetgps"> 

     <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 
     <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
     <uses-feature android:name="android.hardware.location.gps" /> 
     <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"/> 
     <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> 
     <uses-permission android:name="android.permission.INTERNET"/> 

     <application 
      android:allowBackup="true" 
      android:icon="@mipmap/ic_launcher" 
      android:label="@string/app_name" 
      android:supportsRtl="true" 
      android:theme="@style/AppTheme"> 
      <activity android:name=".MainActivity"> 
       <intent-filter> 
        <action android:name="android.intent.action.MAIN" /> 

        <category android:name="android.intent.category.LAUNCHER" /> 
       </intent-filter> 
      </activity> 
     </application> 

    </manifest> 

Dies ist die Botschaft, die ich auf der Konsole:

Answer 1

Wenn Sie schauen die Log-Katze sorgfältig Sie können das

finden

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> 

fehlt.

Für Android Unter Android 6.0 (API 23) und höher müssen wir eine Laufzeitberechtigung hinzufügen.

Siehe diese Antwort zu ihrer Umsetzung:

ACCESS_FINE_LOCATION permissions
