ndk-build

I'm getting this warning while running $ANDROID_NDK_ROOT/ndk-build . The Android.mk is below. $ $ANDROID_NDK_ROOT/ndk-build WARNING:/Users/jwalton/Android-CryptoPP/jni/Android.mk:prng: non-system libraries in linker flags: -lcryptopp -lstlport_shared This is likely to result in incorrect builds. Try using LOCAL_STATIC_LIBRARIES or LOCAL_SHARED_LIBRARIES instead to list the library dependencies of the current module ... However, when I follow the instructions and remove -lcryptopp -lstlport_shared from LOCAL_LDLIBS , then I get link errors related to symbols from libstlport_shared.so . A sample

I need to specify the path of library in Application.mk file to link it correctly. How to do this? Is there any GCC command for that? hukka You have to add LOCAL_LDLIBS := -L/path/to/the/library into the file Android.mk . Add -L/path/to/the/library flag to gcc command line parameters. 来源： https://stackoverflow.com/questions/6475944/how-to-specify-path-of-libraries-in-android-mk-file-or-application-mk-file

What is the actual difference between CMake and NDK build in android studio project. I already went through google documentation but the concept is not clear yet. As per google documentation: The Android Native Development Kit (NDK): a toolset that allows you to use C and C++ code with Android, and provides platform libraries that allow you to manage native activities and access the physical device components, such as sensors and touch input. CMake: an external build tool that works alongside Gradle to build your native library. You do not need this component if you only plan to use ndk-build.

I have been trying to get Gstreamer working in Android studio, following their tutorials, see for example here: https://gstreamer.freedesktop.org/documentation/tutorials/android/link-against-gstreamer.html But in the latest Android studio there is no jni/Android.mk. Where do I put the code at the end of that web page? Should it go in the CMakeLists.txt? Or should something different go in there? Or do I just make an Android.mk file, and if so, where (as there is no jni folder, only a cpp folder)? And how do I tell Android studio where to find my Android.mk file? Thanks! I've made all tutorials

I have an Android project with native code. I'm able to build native code from command line by calling ndk-build command with no errors or warnings. But when I open it in ADT it shows the following error. Error message: Method CallStaticIntMethod could not be resolved. There are many files with similar errors in the project. I double checked configuration and here is what I have. Android build, tool chain and includes are properly configured (see pictures below) Required includes are also visible in the Project Explorer and they are valid (not empty and point to correct header files). But when

I use a native library in my application that is only compiled for armeabi, armeabi-v7a and x86. When this library is loaded on a 64-bit device like the Samsung S6, the application crashes with an UnsatisfiedLinkError java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.myapp-2/base.apk"],nativeLibraryDirectories=[/data/app/com.myapp-2/lib/arm64, /vendor/lib64, /system/lib64]]] couldn't find "libfoo.so" at java.lang.Runtime.loadLibrary(Runtime.java:366) at java.lang.System.loadLibrary(System.java:989) The library is closed source unfortunately.
