Simple and easy to use toolkit for dynamic instrumentation of Dalvik code. Instrumentation is based on library injection and hooking method entry points (in-line hooking). The actual instrumentation code is written using the JNI interface.
The DDI further supports loading additional dex classes into a process. This enables instrumentation code to be partially written in Java and thus simplifies interacting with the instrumented process and the Android framework.
Simple custom view of a beating heart using scaling animation. Has option to set the duration of animation based on BPM (beats per minute).
