The application may be doing too much work on its main thread.

I used SimpleDraweeView in adapter, but my app runs slowly, and I saw the log below:

I/Choreographer(1378): Skipped 55 frames! The application may be doing too much work on its main thread.

so I comment the code mSimpleDraw.setImageUri, the app runs fluently. I think the SimpleDraw blocks the main thread when fetching image from network.

Replacing

view.setImageURI(Uri.parse("content://...");

with

ImageRequest imageRequest =
        ImageRequestBuilder.newBuilderWithSource(Uri.parse("content://...")
                .setResizeOptions(
                        new ResizeOptions(150, 150))
                .build();
DraweeController draweeController = Fresco.newDraweeControllerBuilder()
        .setImageRequest(imageRequest)
        .setOldController(view.getController())
        .setAutoPlayAnimations(true)
        .build();
view.setController(draweeController);

in my code above fixes the performance problem. If I comment out the setResizeOptions line the performance problem comes back. Perhaps something to do with rescaling on the main thread?
