title: Null pointer after capturing image using android camera
body: <p>in my application,i am using android devices camera to capture an image. for some devices it works fine but some are not. I just tested it on LG nexus 4 E960, after i captured the image my application went crash without able to save the result.
  this is my code:</p>
  
  <pre><code>//Using intent to open camera
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent,CAMERA_CAPTURE); 
  </code></pre>
  
  <p>in the activityResult :</p>
  
  <pre><code>protected void onActivityResult(int requestCode, int resultCode, Intent data)
  {
      if(resultCode==RESULT_OK)
      {
          if(requestCode==CAMERA_CAPTURE)
          {   
              Bitmap pictTaken = null ;
              Bundle extras = data.getExtras();
              if(extras.keySet().contains("data"))
              {
                  pictTaken = (Bitmap) extras.get("data");
                  picUri = getIntent().getData();
              }
                      else{
                       picUri = getIntent().getData();
                  try {
                      pictTaken = decodeUri(picUri);
                  } catch (FileNotFoundException e) {
                      // TODO Auto-generated catch block
                      e.printStackTrace();
                  }
                       }
              Intent cropIntent= new Intent (this, Crop.class);
              cropIntent.putExtra("data", picUri.toString());
              cropIntent.putExtra("pict", pictTaken);
              cropIntent.putExtra("code","camera");
              startActivity(cropIntent);
              }
          }
