Android 6.0 (Marshmallow) READ_CONTACTS Erlaubnis erlaubt, Name des Kontakts zu lesen, wenn Erlaubnis verweigert wird

Question

Ich möchte überprüfen, wie neues Erlaubnismodell so in den Einstellungen der Anwendung funktioniert, die ich Contacts abstelle. Dann gehe ich App und versuchen Contacts zu lesen und ... es funktioniert irgendwie:

try { 
    Uri result = data.getData(); 
    int contentIdx; 
    cursor = getContentResolver().query(result, null, null, null, null); 
    contentIdx = cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER); 
    if(cursor.moveToFirst()) { 
     content = cursor.getInt(contentIdx); 
    } 

    if(content > 0) { 
     contentIdx = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME); 
     if(cursor.moveToFirst()) { 
      name = cursor.getString(contentIdx); 
     } 
     contentIdx = cursor.getColumnIndex(BaseColumns._ID); 
     if(cursor.moveToFirst()) { 
      content = cursor.getLong(contentIdx); 
     } 
     cursor = managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, new String[] { Phone.NUMBER }, Data.CONTACT_ID + "=?", new String[] { String.valueOf(content) }, null); 
     if(cursor.moveToFirst()) { 
      number = cursor.getString(cursor.getColumnIndex(Phone.NUMBER)); 
     } 
    } 
} catch (Exception e) { 
    //SecurityException 
} 

• Ich bin in der Lage Kontakt Namen
• zu lesen, wenn ich versuche, Contact Nummer zu lesen SecurityException geworfen wird

java.lang.SecurityException: Permission Denial: Lesen com.android.providers.contacts.HtcContactsProvider2 uri Inhalt: //com.android.contacts/data/phones von pid = 20123, uid = 10593 erfordert android. Genehmigung. READ_CONTACTS oder grantUriPermission()

Warum ist das?

Android Eibisch hat neues Berechtigungssystem. Sie müssen zur Laufzeit Berechtigungen anfordern. http://developer.android.com/training/permissions/requesting.html.

Beispiel:

@Override 
public void onClick(View v) { 
    switch (v.getId()){ 
     case R.id.tv_contact:{ 
      askForContactPermission(); 
      break; 
     } 
    } 
} 

private void getContact(){ 
    Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); 
    startActivityForResult(intent, PICK_CONTACT); 
} 

public void askForContactPermission(){ 
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
     if (ContextCompat.checkSelfPermission(getActivity(),Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) { 

      // Should we show an explanation? 
      if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), 
        Manifest.permission.READ_CONTACTS)) { 
       AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 
       builder.setTitle("Contacts access needed"); 
       builder.setPositiveButton(android.R.string.ok, null); 
       builder.setMessage("please confirm Contacts access");//TODO put real question 
       builder.setOnDismissListener(new DialogInterface.OnDismissListener() { 
        @TargetApi(Build.VERSION_CODES.M) 
        @Override 
        public void onDismiss(DialogInterface dialog) { 
         requestPermissions(
           new String[] 
             {Manifest.permission.READ_CONTACTS} 
           , PERMISSION_REQUEST_CONTACT); 
        } 
       }); 
       builder.show(); 
       // Show an expanation to the user *asynchronously* -- don't block 
       // this thread waiting for the user's response! After the user 
       // sees the explanation, try again to request the permission. 

      } else { 

       // No explanation needed, we can request the permission. 

       ActivityCompat.requestPermissions(getActivity(), 
         new String[]{Manifest.permission.READ_CONTACTS}, 
         PERMISSION_REQUEST_CONTACT); 

       // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an 
       // app-defined int constant. The callback method gets the 
       // result of the request. 
      } 
     }else{ 
      getContact(); 
     } 
    } 
    else{ 
     getContact(); 
    } 
} 

@Override 
public void onRequestPermissionsResult(int requestCode, 
             String permissions[], int[] grantResults) { 
    switch (requestCode) { 
     case PERMISSION_REQUEST_CONTACT: { 
      // If request is cancelled, the result arrays are empty. 
      if (grantResults.length > 0 
        && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
       getContact(); 
       // permission was granted, yay! Do the 
       // contacts-related task you need to do. 

      } else { 
       ToastMaster.showMessage(getActivity(),"No permission for contacts"); 
       // permission denied, boo! Disable the 
       // functionality that depends on this permission. 
      } 
      return; 
     } 

     // other 'case' lines to check for other 
     // permissions this app might request 
    } 
}
