I noticed performance issues on the HTC one when going from 4.1 to 4.3 or 4.2. Disabling hardware acceleration actually improved performance on many pages when using the HTC One.

Other devices had great performance for the same pages with hardware acceleration enabled. It's only the HTC one that struggled and needed the below code:

if(!(android.os.Build.MODEL.equalsIgnoreCase("HTC One") && Integer.parseInt(android.os.Build.VERSION.SDK) == 18)) { getWindow().setFlags(WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED, WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED); }

Try to start method profiling (see picture), then launch your activity, then stop method profiling by hitting the same button in the picture again. Eclipse will generate a report where you will see which method takes what time to execute. Thus you can find out which method caused the delay.
