java.lang.SecurityException：權限拒絕：IMAGE_CAPTURE開始意圖

我正在使用Android M 6.0.1在我的Nexus 5上調試我的應用程序，並且出現相機權限問題。在我的應用程序需要打開相機的按鈕被點擊時，卻引發我此異常：java.lang.SecurityException：權限拒絕：IMAGE_CAPTURE開始意圖

我已經添加了讀許可/寫外部文件夾和相機我的清單：

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

這是我嘗試啓動相機的方法：

private void startCameraActivity() 
{ 
    try 
    { 
     Log.d("debug", "sto provando a lanciare la fotocamera"); 
     String IMGS_PATH = Environment.getExternalStorageDirectory().toString() + "/TesseractSample/imgs"; 
     prepareDirectory(IMGS_PATH); 

     String img_path = IMGS_PATH + "/ocr.jpg"; 

     outputFileUri = Uri.fromFile(new File(img_path)); 

     final Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 

     if (takePictureIntent.resolveActivity(getPackageManager()) != null) { 
      startActivityForResult(takePictureIntent, PHOTO_REQUEST_CODE); 
     } 
    } 
    catch (Exception e) 
    { 
     e.printStackTrace(); 
    } 
}

我認爲問題是，要求攝像機的權限從未顯示。當我的活動啓動時，它會要求我讀取/寫入外部存儲器，但絕對不能用於相機。我已經採取了網絡上的權限的代碼。它使用這個類：

public class RequestPermissionsToolToolImpl implements RequestPermissionsTool 
{ 
    private static final String CONFIRMATION_DIALOG = "ConfirmationDialog"; 
    private static final String TAG = RequestPermissionsToolToolImpl.class.getSimpleName(); 
    private Activity activity; 

    @Override 
    public void requestPermissions(Activity activity, String[] permissions) 
    { 
     Log.d("debug", "sto chiedendo i permessi."); 
     int x = 0; 

     Map<Integer, String> permissionsMap = new HashMap<>(); 
     this.activity = activity; 


     for (int i = 0; i < permissions.length; i++) { 
      permissionsMap.put(i, permissions[i]); 
     } 

     for (Map.Entry<Integer, String> permission : permissionsMap.entrySet()) 
     { 
      if (!isPermissionGranted(activity, permission.getValue())) 
      { 
       if (ActivityCompat.shouldShowRequestPermissionRationale(activity, permission.getValue())) 
       { 
        ConfirmationDialog.newInstance(permission.getKey(), permission.getValue()).show(activity.getFragmentManager(), CONFIRMATION_DIALOG); 
       } 
       else { 
        ActivityCompat.requestPermissions(activity, permissions, 
          permission.getKey()); 
        return; 
       } 
      } 
     } 
    } 

    @Override 
    public boolean isPermissionsGranted(Context context, String[] permissions) { 

     for (String permission : permissions) 
     { 
      if (!isPermissionGranted(context, permission)) { 
       return false; 
      } 
     } 
     return true; 
    } 

    @Override 
    public void onPermissionDenied() { 
     ErrorDialog.newInstance("Permission needs"). 
       show(activity.getFragmentManager(), CONFIRMATION_DIALOG); 
    } 

    private boolean isPermissionGranted(Context context, String permission) 
    { 
     return ActivityCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED; 
    } 


    /** 
    * Shows OK/Cancel confirmation dialog about permission. 
    */ 
    public static class ConfirmationDialog extends DialogFragment 
    { 

     private static final String ARG_PERMISSION = "permission"; 
     private static final String ARG_REQUEST_CODE = "request_code"; 

     public static ConfirmationDialog newInstance(int permissionKey, String permissionValue) { 
      ConfirmationDialog dialog = new ConfirmationDialog(); 
      Bundle bundle = new Bundle(); 
      bundle.putString(ARG_PERMISSION, permissionValue); 
      bundle.putInt(ARG_REQUEST_CODE, permissionKey); 
      dialog.setArguments(bundle); 
      return dialog; 
     } 

     @Override 
     public Dialog onCreateDialog(Bundle savedInstanceState) { 

      return new AlertDialog.Builder(getActivity()) 
        .setMessage("Please allow permission") 
        .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() { 
         @Override 
         public void onClick(DialogInterface dialog, int which) { 

          ActivityCompat.requestPermissions(getActivity(), 
            new String[]{getArguments().getString(ARG_PERMISSION)}, 
            getArguments().getInt(ARG_REQUEST_CODE)); 
         } 
        }) 
        .setNegativeButton(android.R.string.cancel, 
          new DialogInterface.OnClickListener() { 
           @Override 
           public void onClick(DialogInterface dialog, int which) { 
            Toast.makeText(getActivity(), "Not available", Toast.LENGTH_SHORT).show(); 
           } 
          }) 
        .create(); 
     } 
    } 

    /** 
    * Shows an error message dialog. 
    */ 
    public static class ErrorDialog extends DialogFragment { 

     private static final String ARG_MESSAGE = "message"; 

     public static ErrorDialog newInstance(String message) { 
      ErrorDialog dialog = new ErrorDialog(); 
      Bundle args = new Bundle(); 
      args.putString(ARG_MESSAGE, message); 
      dialog.setArguments(args); 
      return dialog; 
     } 

     @Override 
     public Dialog onCreateDialog(Bundle savedInstanceState) { 
      final Activity activity = getActivity(); 
      return new AlertDialog.Builder(activity) 
        .setMessage(getArguments().getString(ARG_MESSAGE)) 
        .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() { 
         @Override 
         public void onClick(DialogInterface dialogInterface, int i) { 
//nothing 
         } 
        }) 
        .create(); 
     } 

    } 
}

，這些都是在我的活性的方法，它使用權限：

private void requestPermissions() 
    { 
     String[] permissions = new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}; 
     requestTool = new RequestPermissionsToolToolImpl(); 
     requestTool.requestPermissions(this, permissions); 
    } 

    @Override 
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { 

     boolean grantedAllPermissions = true; 
     for (int grantResult : grantResults) { 
      if (grantResult != PackageManager.PERMISSION_GRANTED) { 
       grantedAllPermissions = false; 
      } 
     } 

     if (grantResults.length != permissions.length || (!grantedAllPermissions)) { 

      requestTool.onPermissionDenied(); 
     } else { 
      super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
     } 
    }

試試這個[輸入鏈接描述]（http://stackoverflow.com/questions/32789027/android-m-camera-intent-permission-bug） –

@Alexander Palshyn非常感謝你，我已經刪除了相機許可的聲明在我的清單，現在它的作品。我完全沒有意識到Google相機沒有聲明相機權限。 – Clyky

使用這種簡單的片碼在Android M or after versions

public static final int REQUEST_CAMERA = 111; 

void checkPermissionToOpenCamera(){ 
if (Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) { 
       if (ActivityCompat.checkSelfPermission(ProfileActivity.this, Manifest.permission.CAMERA) 
         != PackageManager.PERMISSION_GRANTED && 
         ActivityCompat.checkSelfPermission(ProfileActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) 
           != PackageManager.PERMISSION_GRANTED) { 
        if (ActivityCompat.shouldShowRequestPermissionRationale(ProfileActivity.this, 
          Manifest.permission.CAMERA)) { 
         AlertDialog.Builder alertBuilder = new AlertDialog.Builder(ProfileActivity.this); 
         alertBuilder.setCancelable(false); 
         alertBuilder.setTitle("Permission necessary"); 
         alertBuilder.setMessage("Camera and Gallery permissions are necessary"); 
         alertBuilder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() { 
          @TargetApi(Build.VERSION_CODES.JELLY_BEAN) 
          public void onClick(DialogInterface dialog, int which) { 
           ActivityCompat.requestPermissions(ProfileActivity.this, 
             new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, 
             REQUEST_CAMERA); 
          } 
         }); 
         AlertDialog alert = alertBuilder.create(); 
         alert.show(); 
        } else { 
         ActivityCompat.requestPermissions(ProfileActivity.this, 
           new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, 
           REQUEST_CAMERA); 
        } 
       } else { 
        startCameraActivity(); 
       } 
      } else { 
       startCameraActivity(); 
      } 
      }

檢查權限打開相機狀態接受或拒絕通過onRequestPermissionsResult這樣的檢查是這樣的：

@Override 
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
    switch (requestCode) { 
    case REQUEST_CAMERA: 
      if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
       startCameraActivity(); 
      } else { 
      Log.d(TAG,"You will not able to Upload your Profile picture"); 
      } 
      break;

感謝您的回答，但您的解決方案無法正常工作。它仍然給我安全例外。 – Clyky
