Android M Kamera Sicherheit Ausnahme

Question

Ich habe eine Option für den Benutzer Selfie in meiner Aktivität zu nehmen. Hier ist mein Code für das gleiche:

int REQUEST_CAMERA = 0, SELECT_FILE = 1; 
private static final int REQUEST_SELFIE = 123; 
private static String[] PERMISSIONS_SELFIE = {Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.CAMERA}; 
LinearLayout selfie = (LinearLayout) findViewById(R.id.selfie); 
     selfie.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       if ((ContextCompat.checkSelfPermission(SelfieActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) 
         != PackageManager.PERMISSION_GRANTED) && 
         (ContextCompat.checkSelfPermission(SelfieActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) 
         && (ContextCompat.checkSelfPermission(SelfieActivity.this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)) { 
        requestCameraAndExternalPermission(); 
       } else { 
        takeSelfie(); 
       } 
      } 
     }); 

private void requestCameraAndExternalPermission() { 
     ActivityCompat.requestPermissions(this, PERMISSIONS_SELFIE, REQUEST_SELFIE); 
    } 

@Override 
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { 
     if (requestCode == REQUEST_SELFIE) { 
      if (grantResults.length == 3 && grantResults[0] == PackageManager.PERMISSION_GRANTED 
        && grantResults[1] == PackageManager.PERMISSION_GRANTED 
        && grantResults[2] == PackageManager.PERMISSION_GRANTED) { 
       Toast.makeText(getApplicationContext(), "Permission Granted", Toast.LENGTH_SHORT).show(); 
       takeSelfie(); 
      } else { 
       Toast.makeText(getApplicationContext(), "Some Permissions Denied", Toast.LENGTH_SHORT).show(); 
      } 
     } else if (requestCode == REQUEST_ALBUM) { 
      if (grantResults.length == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
       Toast.makeText(getApplicationContext(), "Permission Granted", Toast.LENGTH_SHORT).show(); 
       openGallery(); 
      } else { 
       Toast.makeText(getApplicationContext(), "Permission Denied", Toast.LENGTH_SHORT).show(); 
      } 
     } else { 
      super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
     } 
    } 

private void takeSelfie() { 
     Intent intent = new Intent("android.media.action.IMAGE_CAPTURE"); 
     File file = new File(Environment.getExternalStorageDirectory() + File.separator + "image.jpg"); 
     if (file.exists()) { 
      file.delete(); 
      file = new File(Environment.getExternalStorageDirectory() + File.separator + "image.jpg"); 
     } 
     intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file)); 
     startActivityForResult(intent, REQUEST_CAMERA); 
    } 

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     if (resultCode == RESULT_OK) { 
      if (requestCode == REQUEST_CAMERA) { 
       File destination = new File(Environment.getExternalStorageDirectory() + File.separator + "image.jpg"); 
       imagePath = destination.getAbsolutePath(); 
       Intent intent = new Intent(SelfieActivity.this, PhotoAdjustActivity.class); 
       intent.putExtra("path", imagePath); 
       startActivity(intent); 
      } else if (requestCode == SELECT_FILE && data != null) { 
        Uri selectedImageUri = data.getData(); 
        String[] projection = {MediaStore.MediaColumns.DATA}; 
        Cursor cursor = getContentResolver().query(selectedImageUri, projection, null, null, 
          null); 
        assert cursor != null; 
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA); 
        cursor.moveToFirst(); 
        imagePath = cursor.getString(column_index); 
        if (imagePath == null) { 
         imagePath = getActualPathFromUri(selectedImageUri); 
        } 
        Intent intent = new Intent(SelfieActivity.this, PhotoAdjustActivity.class); 
        intent.putExtra("path", imagePath); 
        intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION); 
        startActivity(intent); 
        overridePendingTransition(0, 0); 
        cursor.close(); 
      } 
     } 
    } 

Wenn ich auf meinem Telefon geprüft (Lenovo K3 Hinweis), es funktioniert gut. Aber heute habe ich einen Absturz in Motorola (Android 6). Dies ist der Absturz:

Fatal Exception: java.lang.SecurityException 
Permission Denial: starting Intent { act=android.media.action.IMAGE_CAPTURE flg=0x3 cmp=com.motorola.camera/.Camera clip={text/uri-list U:file:///storage/emulated/0/image.jpg} (has extras) } from ProcessRecord{735d251 15134:com.galleri5.android/u0a149} (pid=15134, uid=10149) with revoked permission android.permission.CAMERA 

Hier ist mein Manifest:

<uses-permission android:name="android.permission.INTERNET" /> 
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> 
    <uses-permission android:name="android.permission.VIBRATE" /> 

    <uses-feature android:name="android.hardware.camera.autofocus" 
     android:required="false"/> 

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

    <uses-feature 
     android:name="android.hardware.camera" 
     android:required="false" /> 

Was ist der Grund dafür sein könnte, und wie soll ich dieses Problem beheben?

Answer 1

Ihr Problem Es ist in onClick Funktion, versuchen Sie mit diesem:

public void onClick(View v) { 
       if ((ContextCompat.checkSelfPermission(SelfieActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) 
         != PackageManager.PERMISSION_GRANTED) && 
         (ContextCompat.checkSelfPermission(SelfieActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) 
         && (ContextCompat.checkSelfPermission(SelfieActivity.this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)) { 
        requestCameraAndExternalPermission(); 
       } else { 
        if (grantResults.length == 3 && grantResults[0] == PackageManager.PERMISSION_GRANTED 
        && grantResults[1] == PackageManager.PERMISSION_GRANTED 
        && grantResults[2] == PackageManager.PERMISSION_GRANTED) { 
       Toast.makeText(getApplicationContext(), "Permission Granted", Toast.LENGTH_SHORT).show(); 
       takeSelfie(); 
        } else { 
         Toast.makeText(getApplicationContext(), "Some Permissions Denied", Toast.LENGTH_SHORT).show(); 
        } 
       } 
      }
