I needed  to get an intro to Android Malware Analysis and some of the tools you can use for Analysis. This books is very easy to read and provides a good foundation to start doing Android Malware Analysis. It covers current malware landscape until 2014 an existing techniques and tools in static and dynamic analysis. I highly recommend this book and the tools in it if you are planning to start doing Android Malware Analysis.
