java.lang.RuntimeException: Fehler beim Liefern des Ergebnisses ResultInfo erfordert android.permission.READ_EXTERNAL_STORAGE oder grantUriPermissio

Question

Ich folge einem Tutorial Video von Android auf Server auf diesem link hochladen. Aber wenn ich diese Aktivität ausführe, gab es mir eine Laufzeit-Ausnahme. Laut der Ausnahme habe ich Berechtigungen in der manifest Datei hinzugefügt. Aber immer noch den Fehler zu bekommen. Hier ist meine Aktivitätsdatei

public class UploadActivity extends AppCompatActivity implements View.OnClickListener { 
    private Button buttonChoose; 
    private Button buttonUpload; 
    private TextView textView; 
    private TextView textViewResponse; 
    private static final int SELECT_VIDEO = 3; 
    private String selectedPath; 
    public void onCreate(Bundle savedInstanceState){ 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_upload); 
     report = getIntent().getStringExtra("report"); 
     buttonChoose = (Button) findViewById(R.id.buttonChoose); 
     buttonUpload = (Button) findViewById(R.id.buttonUpload); 
     textView = (TextView) findViewById(R.id.textView); 
     textViewResponse = (TextView) findViewById(R.id.textViewResponse); 
     buttonChoose.setOnClickListener(this); 
     buttonUpload.setOnClickListener(this); 
    } 
    private void chooseVideo() { 
     Intent intent = new Intent(); 
     intent.setType("video/*"); 
     intent.setAction(Intent.ACTION_GET_CONTENT); 
     startActivityForResult(Intent.createChooser(intent, "Select a Video "), SELECT_VIDEO); 
    } 
    @Override 
    public void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (resultCode == RESULT_OK) { 
      if (requestCode == SELECT_VIDEO) { 
       System.out.println("SELECT_VIDEO"); 
       Uri selectedImageUri = data.getData(); 
       selectedPath = getPath(selectedImageUri); 
       textView.setText(selectedPath); 
      } 
     } 
    } 
    public String getPath(Uri uri) { 
     Cursor cursor = getContentResolver().query(uri, null, null, null, null); 
     cursor.moveToFirst(); 
     String document_id = cursor.getString(0); 
     document_id = document_id.substring(document_id.lastIndexOf(":") + 1); 
     cursor.close(); 
     cursor = getContentResolver().query(
       android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI, 
       null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null); 
     cursor.moveToFirst(); 
     String path = cursor.getString(cursor.getColumnIndex(MediaStore.Video.Media.DATA)); 
     cursor.close(); 
     return path; 
    } 

    private void uploadVideo() { 
     class UploadVideo extends AsyncTask<Void, Void, String> { 
      ProgressDialog uploading; 
      @Override 
      protected void onPreExecute() { 
       super.onPreExecute(); 
       uploading = ProgressDialog.show(UploadActivity.this, "Uploading File", "Please wait...", false, false); 
      } 
      @Override 
      protected void onPostExecute(String s) { 
       super.onPostExecute(s); 
       uploading.dismiss(); 
       textViewResponse.setText(Html.fromHtml("<b>Uploaded at <a href='" + s + "'>" + s + "</a></b>")); 
       textViewResponse.setMovementMethod(LinkMovementMethod.getInstance()); 
      } 

      @Override 
      protected String doInBackground(Void... params) { 
       UploadFile u = new UploadFile(); 
       String msg = u.uploadVideo(selectedPath); 
       return msg; 
      } 
     } 
     UploadVideo uv = new UploadVideo(); 
     uv.execute(); 
    } 

    @Override 
    public void onClick(View v) { 
     if (v == buttonChoose) { 
      chooseVideo(); 
     } 
     if (v == buttonUpload) { 
      uploadVideo(); 
     } 
    } 
} 

Hier ist die logcat

private static final int REQUEST_STORAGE = 112; 

    @Override 
     public void onClick(View v) { 
     if (v == buttonChoose) { 
      if (Build.VERSION.SDK_INT >= 23) { 
       String[] PERMISSIONS = {android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.READ_EXTERNAL_STORAGE}; 
       if (!hasPermissions(mContext, PERMISSIONS)) { 
        ActivityCompat.requestPermissions((Activity) mContext, PERMISSIONS, REQUEST_STORAGE); 
       } else { 
         chooseVideo(); 
       } 
      } else { 
       chooseVideo(); 
      } 
     } 
     if (v == buttonUpload) { 
      uploadVideo(); 
     } 
    } 

get Berechtigungen Ergebnis

@Override 
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { 
     super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
     switch (requestCode) { 
      case REQUEST_STORAGE: { 
       if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

        chooseVideo(); 
       } else { 
        Toast.makeText(mContext, "The app was not allowed to write to your storage.", Toast.LENGTH_LONG).show(); 
       } 
      } 
     } 
    } 

Kontrollberechtigungen für Eibisch

private static boolean hasPermissions(Context context, String... permissions) { 
     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) { 
      for (String permission : permissions) { 
       if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) { 
        return false; 
       } 
      } 
     } 
     return true; 
    } 

Manifest

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