I assume that the pasted code is part of the ImageBrowserActivity ? So which exactly is the line number 177 ?

xifan-xf commented 8 years ago

line number 177: 

 PooledByteBufferInputStream sourceIs = new PooledByteBufferInputStream(pooledByteBuffer);

The subscriber should not be assumed to be running on the UI thread. This error happens when you try to touch UI elements from a non-UI thread.
