android: Bildaufnahme von Kamera ein Null es bekommen

Question

ich die „Photofile“ bin immer null in onActivityResult()

auf Aufnahmetaste klicken ich eine Methode dispatchTakePictureIntent() aufrufen Aber wenn ich es null bekommen wieder zurück .

Dieses Problem ist dann auftreten, wenn die Bildauflösung/Größe wie 4012 * 4012 usw. Sehr groß ist und speziell geschehen auf Android-Version 6.0 +

Hier ist mein Code

private void dispatchTakePictureIntent() { 
    Intent takePictureIntent = new Intent(
      android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    // Ensure that there's a camera activity to handle the intent 
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) { 
     // Create the File where the photo should go 
     File photoFile = null; 
     try { 
      photoFile = Util.createImageFile(); 
      mCurrentPhotoPath = photoFile.getAbsolutePath(); 

      System.out.println("photoFile:" + photoFile.getAbsolutePath()); 
     } catch (IOException ex) { 
      ex.printStackTrace(); 
     } 
     // Continue only if the File was successfully created 
     if (photoFile != null) { 

      System.out.println("@@@@ photoFile: " + photoFile.getAbsolutePath()); 

      /*takePictureIntent.putExtra(MediaStore.EXTRA_SIZE_LIMIT,1024); 
      takePictureIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, 
        mCurrentPhotoPath);*/ 

      takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, 
        Uri.fromFile(photoFile)); 

      startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE); 

     } 
    } 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 

    if (resultCode != RESULT_CANCELED) { 
     if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) { 
      try { 
       //Bundle extras = data.getExtras(); 
       // Log.i(TAG, "extras: " + extras.get("data")); 

       Bitmap mphoto = (Bitmap) data.getExtras().get("data"); 


       System.out.println("***photoFile: " + data.getExtras().get("data")); 

      } catch (Exception e) { 
       // Log.i(TAG, "Exception:" + e.getMessage()); 
      } 

      ShowPopupDialog(mCurrentPhotoPath); 
     } 

    } 
} 

Bitte mir helfen. Danke im Voraus.

Ändern Sie Ihre OnActivityResult Code:

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 

     if (resultCode != RESULT_CANCELED) { 
      if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) { 
       try {  

         File fil = new File(Environment.getExternalStorageDirectory().toString()); 
          for (File temp : fil.listFiles()) { 
           if (temp.getName().equals("temp.jpg")) { 
            fil = temp; 
            break; 
           } 
          } 
          Bitmap bitmap = null; 

          BitmapFactory.Options bitmapOptions = new BitmapFactory.Options(); 
          Bitmap bmp = BitmapFactory.decodeFile(fil.getAbsolutePath(),bitmapOptions); 
    // 
          Log.e("edit", "new image path is " + fil.getAbsolutePath()); 
       } catch (Exception e) { 
        // Log.i(TAG, "Exception:" + e.getMessage()); 
       } 

       ShowPopupDialog(mCurrentPhotoPath); 
      } 

     }
