I want design static taint analysis for Android apps . and which can detect potential privacy leaks. it will improve and develop existing features such as lifecycle modelling, context, field, object, and flow sensitivity, in addition to new features. This will improve the time of compilation, response time of the application, and enhance the performance. Also, this plays an important role in reducing resource costs and the amount of memory used. also compared with static analysis previous tools and show the results on Droidbench.
