Get the Android NDK and unzip. Use objdump
as follows:
android-ndk-r9d\toolchains\arm-linux-androideabi-4.6\prebuilt\windows-x86_64\arm-linux-androideabi\bin\objdump.exe -d libinquestion_jni.so > libinquestion_jni.txt
While trying different disassemblers, I explored that they are not capable to decode every byte sequence, and even worse, they can decode in a wrong way making you wonder how does it ever work. Different ARMs have different instruction sets and use overlapping byte encodings for them. objdump
from the Android NDK is a perfect match for CPUs used in Android products, and it's free.
