You don’t need to use -O0 or -g switches. You need to do one of following: put android:debuggable=”true” to the <application> tag in AndroidManifest.xml file use NDK_DEBUG=1 after ndk-build put APP_OPTIM := debug in Application.mk file Doing anyone of these three things will automatically use -O0 and -g switches.

What are “unused DT entry” errors? If you have reached this page, it’s probably because you have compiled or attempted to run some binaries on your ARM based Android system, with the result that your binary/app crashes or generates a lot of warnings in your logcat.

As I understand it, the correct method is to use ndk-build and not invoking the compiler directly. In Android.mk you need to specify a module for each static library you want to compile, and then specify that your shared library should use it.

There are samples in the android-ndk-r5 folder + there is a nice step-by-step tutorial: https://developer.android.com/ndk/samples/index.html No excuses, dude. You just have to read (take a look at the Exploring the hello-jni Sample section).

The ndk files (.so) are … Read more
EDIT: Since I got another crash report yesterday for one of my apps I dug a bit deeper into the matter and found a third very likely explanation for that problem: Google Play Partial APK Update Goes Wrong To be honest, I did not know about that feature.
