Does not work in ART, Dalvik only. To change the mode, do the following:
1. Starting from Android 4.2.2 Jelly Bean, Google has hidden the Developer options from the Settings menu. To activate it, head over to Settings -> About Phone and tap on ‘Build number’ seven times.
2. Go back to Settings and open Developer options. Find and tap Select runtime and then select the Use Dalvik option.
