FATAL EXCEPTION: AsyncTask #1 SkImageDecoder::Factory returned null
<p>When i run this code i get errors sometimes but not allways.
I cant see my error.</p>

<p>Calling Code:</p>

<pre><code>private void processPhotoUpdate(File tempFile)
        {
            Log.i(TAG, "Made it into Process Photo Update" );
            ProcessProfilePhotoTask task = new ProcessProfilePhotoTask()
                {
                    @Override
                    protected void onPostExecute(Bitmap result)
                        {
                            Log.i(TAG, "Not Null");
                            if (result != null){                    
                            Log.i(TAG, "on Post Execute");
                            android.widget.LinearLayout.LayoutParams params = new android.widget.LinearLayout.LayoutParams(result.getWidth(), result.getHeight());
                            params.gravity = Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL;
                            photo.setLayoutParams(params);
                            photo.setImageBitmap(result);
                            }
                        }
                };                  
                    task.execute(tempFile);
        }
</code></pre>

<p>The class i call is:</p>

<pre><code>public class ProcessProfilePhotoTask extends AsyncTask&lt;File, ProcessProfilePhotoTask.ProcessingState, Bitmap&gt; {


public enum ProcessingState {
    STARTING,
    PROCESSING_LARGE,
    FINISHED
}


public static final String TAG = "ProcessProfilePhotoTask";

public ProcessProfilePhotoTask() {
    super();
}

@Override
protected Bitmap doInBackground(File... files) {
    ProcessingState[] s = new ProcessingState[1];
    //BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    if (files.length != 1) {
        throw new IllegalArgumentException("We expect to process only one file");
    }
    try {
        s[0] = ProcessingState.PROCESSING_LARGE;
        publishProgress(s);

        Bitmap largePhoto = BitmapFactory.decodeStream(new FileInputStream(files[0]));
        int height = largePhoto.getHeight();
        int width = largePhoto.getWidth();
        int density = largePhoto.getDensity();
        Log.d(TAG,"large image processing "+ height+"x"+width+"den="+density+"type=");

        return largePhoto;
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        return null;
    }
}
}
