Warum wird die Berechtigung verweigert, nachdem der Benutzer gefragt wurde?

Question

Ich habe die Berechtigungen in meinem manisfest für api 22-:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 
<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission 
    android:name="android.permission.ACCESS_FINE_LOCATION" 
    android:maxSdkVersion="22" /> 
<uses-permission 
    android:name="android.permission.ACCESS_COARSE_LOCATION" 
    android:maxSdkVersion="22" /> 
<uses-permission 
    android:name="android.permission.READ_CONTACTS" 
    android:maxSdkVersion="22" /> 
<uses-permission 
    android:name="android.permission.WRITE_CONTACTS" 
    android:maxSdkVersion="22" /> 
<uses-permission 
    android:name="android.permission.READ_EXTERNAL_STORAGE" 
    android:maxSdkVersion="22" /> 

und die Laufzeitprüfung für Berechtigungen als auch für api 23+:

private void requestGpsPermission() { 
    if (ContextCompat.checkSelfPermission(this, 
      Manifest.permission.READ_CONTACTS) 
      != PackageManager.PERMISSION_GRANTED || 
      ContextCompat.checkSelfPermission(this, 
      Manifest.permission.WRITE_CONTACTS) 
      != PackageManager.PERMISSION_GRANTED) 
     ActivityCompat.requestPermissions(this, new String[]{ 
       Manifest.permission.READ_CONTACTS, 
       Manifest.permission.WRITE_CONTACTS}, 1); 

    if (ContextCompat.checkSelfPermission(this, 
      Manifest.permission.ACCESS_FINE_LOCATION) 
      != PackageManager.PERMISSION_GRANTED || 
      ContextCompat.checkSelfPermission(this, 
        Manifest.permission.ACCESS_COARSE_LOCATION) 
        != PackageManager.PERMISSION_GRANTED) 
     ActivityCompat.requestPermissions(this, new String[]{ 
       Manifest.permission.ACCESS_FINE_LOCATION, 
       Manifest.permission.ACCESS_COARSE_LOCATION}, 2); 

    if (ContextCompat.checkSelfPermission(this, 
      Manifest.permission.READ_EXTERNAL_STORAGE) 
      != PackageManager.PERMISSION_GRANTED) 
     ActivityCompat.requestPermissions(this, new String[]{ 
       Manifest.permission.READ_EXTERNAL_STORAGE}, 3); 
} 

Und ich habe immer noch die Fehler:

Ich versuche, die App in einem Android 6.0-Gerät auszuführen. Irgendeine Idee, wie man es löst?

Answer 1

Nachdem ich für 2 Tage gekämpft habe, habe ich es endlich geschafft. Mir fehlte die folgende Methode:

1 @Override 
2 public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { 
3  // If request is cancelled, the result arrays are empty. 
4  if (grantResults.length > 0 
5    && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
6   // permission granteed 
7  P.toast(this, "permission granteed :-)"); 
8   getHeaders(); 
9  } else { 
10  // permission denied 
11  P.toast(this, "permission denied :-("); 
12 } 
13 return; 
14} 

I als auch die Prüfungsmethode zu ändern hatte, so falls ich bereits über die Berechtigungen Es getHeaders() aufrufen, von dort:

1 private void requestGpsPermission() { 
2  if (
3    ContextCompat.checkSelfPermission(this, 
4      Manifest.permission.READ_CONTACTS) 
5      != PackageManager.PERMISSION_GRANTED || 
6      ContextCompat.checkSelfPermission(this, 
7        Manifest.permission.ACCESS_FINE_LOCATION) 
8        != PackageManager.PERMISSION_GRANTED || 
9      ContextCompat.checkSelfPermission(this, 
10       Manifest.permission.READ_EXTERNAL_STORAGE) 
11       != PackageManager.PERMISSION_GRANTED 
12   ) { 
13  ActivityCompat.requestPermissions(this, new String[]{ 
14    Manifest.permission.READ_CONTACTS, 
15    Manifest.permission.ACCESS_FINE_LOCATION, 
16    Manifest.permission.READ_EXTERNAL_STORAGE 
17  }, 1); 
18 } else { 
19  getHeaders(); 
20 } 
21} 

Beachten Sie, dass ich Rufen Sie die gleiche Methode in Zeile 8 des ersten mehotd und Zeile 19 des zweiten.
