This motivates developers find ways extend liveness time their apps, hence name diehard in this paper. Although there blogs and articles illustrating achieve purpose, is no systematic research about them. What's more important, little known prevalence wild.

Second, prevalent wild? particular, conduct semi -automated analysis illustrate insights existing app could be evaded, then present 12 methods. After that, develop system named DiehardDetector detect large scale. The experimental result applying than 80k downloaded from Google Play showed that around 21 % adopt various Moreover, our high precision recall.
