Just this, the decompilation / recompilation of dex files break the app (not loading the main activity) without any usefull stack trace. When I decompile sources, there is some poorly recompilation that I made? I tried everything, I'm using latest version of apktool (2.9.1) and so on. Then, I'm not able to understand what is happening. NO error messages from Android (crash dialog), NO usefull logs from logcat (I tried also making app debuggable and doing some trials), AFAIK NO signature verification methods or anti-tampering mechanism (I researched and added breakpoint on PackageManager methods, looking at some pattern for those mechanism and so on.). If I decompile also or only the sources (dex files), recompile it then zipalign/sign the app remain stuck on splash screen or sometimes crash going to background. There is a strange thing that happens, probably something new for me, basically if I decompile only the resources (not dex files) and recompile it zipalign/sign, the app installed works fine. I'm trying, for educational purposes, to reverse an apk ( )
