In this paper, we investigate using obfuscation as a security-through-obscurity approach to hide app code vulnerabilities in Android apps. Obfuscation refers to a set of techniques that change the syntax of the code but preserve its semantics. This way, the app maintains the same runtime ...
We propose a code recognition technique that is resilient against common code transformations and that excels in identifying code fragments and libraries in Android applications. Our method relies on obfuscation-resilient features from the Abstract Syntax Tree of methods and uses them in combination with...

When using in development/debug testing, you may wish to turn on a few settings that may add to compile time as well as make it harder to troubleshoot. For instance, to ensure that no code optimizations or obfuscation is done, the following options should be declared in your ProGuard confi...

This enables numerous security analyses, including code inspection and predicting libraries APK Patch Size Estimator - Estimates the size of Google Play patches and the new gzipped APK Battery Historian -...
Assets can be encrypted, while combining other techniques, such as class encryption (seen in several high-profile apps), and bytecode obfuscation (control-flow obfuscation, string encryption, reflected API access). With most bytecode obfuscation being automatically cleaned up, Assets are being accesse...
