Android ndk cannot link function apk#
so files in the apk file again to reconstruct the project or with another project if the java nativeįunction declaration is done appropriately? You can obfuscate the code, but they will see icons, they will find the resource ids, and they will find the onClick() button handlers. Obfuscated code is still readable, provided that they invest some efforts in analysis. One can substitute some function calls by other function calls, and one can add new classes.ĭecompiling to Java is also possible, but the code likely will not compile, so it is rather about analysis than about modification. apk, to fix something in it, and to smali (assemble) it again. It is possible to baksmali (disassemble) an. One can disassemble there are C/C++ decompilers, but for really complex code they are nearly useless.Īnd is it possible from the apk to reconstruct the project and import it to eclipse (or any other IDE)? Is is possible to decode native code compiled and liked to android through ndk ? class files obfuscation of the code can make it harder.Ĭ) Any functionality your app may have, native or not, can quite easily be extracted and exploited by another app the attacker may write.
Android ndk cannot link function how to#
If someone knows how to use your shared library though (easy to figure out, see above), he would be able to use it in whatever app he likes.Ī) The source code cannot be reconstructed from compiled native code.ī) Java source is much easier to reconstruct from compiled. The (source-)code is basically "lost" for good after compilation to native code. The functions and signatures of your native library are probably easy to recover from the corresponding (compiled) Java class in any case. It depends on what you mean with "project". so files in the apk file again to reconstruct the project This is not at all difficult to reverse engineer.
Don't try something like private static String SECRET = "sesame123".
However, constant values and initilizers are very easy to come by from a compiled class. An obfuscation step in your build process will make this a lot more difficult. class files is easy, decompiling mostly too.
