Instrument an Android app to measure the test coverage.

Take method coverage as an example, the steps to measure the method coverage of dyn. analysis are as follows:

1. Analyze the app and get a list of all methods in the app.
2. Instrument the app to print log messages when it reaches a method.
3. Run the app and collect the log messages.
4. Get the list of reached methods.
5. Calculate the coverage (i.e. the percentage of reached methods).
