My app run perfectly on 32bit android devices when I try to run on 64bit devices
its gives me error on build time.

Please suggest what changes need to be done in above code to make it run.

I already answered a similar question... The problem with the official tutorials from the Gstreamer site is that they are old and made for Eclipse. Maybe your error is because you didn't link your Android Studio project to the C++ files... to do it follow the second step from this answer: Gstreamer examples in Android Studio
Since the linking with C++ files ins't the only error that will occurs I also suggest that you follow all other steps. There's a link for gitlab project with "turorial 5" working in the link above.

Unable to reach a break point in C++ using Android Studio and ndkBuild

I'm trying to reach a break point in a simple C++ code:
Here the .cpp
#include <jni.h>
#include <string>
extern "C"
{
jstring Java_com_comscore_android_app_MainActivity_stringFromJNI(
JNIEnv* env,
jobject /* this */) {
std::string hello = "Hello from C++ lalalaaaaaa";
return env->NewStringUTF(hello.c_str());
}
}
here the gradle file:
android {
compileSdkVersion 23
buildToolsVersion "24.0.1"
defaultConfig {
applicationId "com.comscore"
minSdkVersion 10
targetSdkVersion 23
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
externalNativeBuild {
ndkBuild {
arguments "NDK_APPLICATION_MK:=src/main/jni/Application.mk"
}
}
}
externalNativeBuild{
ndkBuild{
path "src/main/jni/Android.mk"
}
}
...
}
The Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := native-lib.cpp
LOCAL_MODULE := native-lib
LOCAL_LDLIBS := -llog
LOCAL_CPPFLAGS += -fsigned-char -fexceptions -frtti -g -O0 -std=c++0x -std=gnu++0x
LOCAL_CFLAGS += -fsigned-char -fexceptions -frtti -g -O0 -std=c++0x -std=gnu++0x
include $(BUILD_SHARED_LIBRARY)
And the Application.mk
APP_ABI := all
APP_STL := gnustl_static
The application compiles and works but I'm not able to stop in any breakpoint in the C++ code while running the debugger. I can see how it loads the native libraries but it doesn't stop any where and Android studio is telling me that the break point has been attached.
I'm using Android Studio 2.2 Preview 6
Can anybody help me?

In my case I have two modules, one with the C++ code (library) and an other one with the application that consumes the library module.
The problem was that I tried to debug the library module uaing the app module, so I just need to specify the folder where the debug symbols are:
Run->Edit configurations... -> Debuggerand in the symbol directories tab add the right path. For instance:
/path_to_my_project/lib_module/build/intermediates/ndkBuild/flavor/debug/obj/local/x86

app.imp file contains "<"facet type="native_android_gradle">", , option=SELECTED_BUILD_VARIANT..
check if value="debug"

Android ndk ffmpeg : Unknown mnemonic error

I'm building a simple video app and want to embed a watermark on the recorded videos. I am using ffmpeg for this process and have successfully compiled it. The issue is when I try to link it with my project in Android Studio using ndk-build.cmd command, it gives me the following error:

My development environment is

First, I installed Cygwin64bit and added 'make', 'dos2unix', 'c++ gcc' packages. And I decompressed ffmpeg folder in C:/android-ndk-r11c/sources. This is the build script I used.

I ran this .sh in Cygwin(as administrator) but it didn't work. So I typed each of those lines on Cygwin and it compiled successfully. I tried both --target-os=android and --target-os=linux, but both didn't solve the problem above.
Then I followed this tutorial (enoent.fr/blog/2014/06/20/compile-ffmpeg-for-android/). Based on that, I made a native method in my project and built header file and c file.(To do that, I followed this video. youtube.com/watch?v=kFtxo7rr2HQ)
After that, I cloned this repo(github.com/HikoQiu/JNI_INVOKE_FFMPEG) and copied - pasted the jni folder into my project. And after making the Android.mk and Application.mk, I ran the C:/android-ndk-r11c/ndk-build.cmd in the Android Studio terminal and it gave me the error above.
These are the Makefiles I used.

Any ideas?

As the last line of your compilation error report says:
make: *** [obj/local/arm64-v8a/objs/myProject_Videokit/ffmpeg.o] Error 1
It's the key. You're trying to build your application for all available ABI's. As I can see your build.gradle file, there's no abiFilter. I'd do it in a next manner (I'm not sure with syntax, but the):
android {
...
ndk {
moduleName "com_example_myProjet_Videokit"
abiFilters = "x86", "armeabi"
}
...
}
If I were you, I'd use gradle-experimental plugin, prebuild ffmpeg libs for all needed ABI's, and then use this approach to load the libraries.
So the main problem - you have one library for all ABI's. It's incorrect.

Trying to use FFMPEG for android. Compiling but still not working

So to start off... Im trying to use ffmpeg to compile an array of images into a video on Android.
I have followed a variety of tutorials online and have gotten as far as being able to compile the lib for Android and still have to project run.
The repo im now using can be found here: https://github.com/Batterii/android-ffmpeg-x264
I made a couple tweaks to the setttings.sh just to correct ndk location. Besides that, I followed the instructions and it seemed to work flawlessly.
After that, I converted the "Project" project into an Android stdio library module.
I am not getting any compile errors, nor am I getting any runtime errors, or any other errors that I can detect... Nothing on logcat... But I am definitely not getting any video called out.mp4.
In an onCreate of a particular activity, I am running this code:
Videokit vk = new Videokit();
vk.run(new String[]{"ffmpeg", "-r", "1/5", "-i", "%d.jpg", "-c:v", "libx264", "-r", "30", "-pix_fmt", "yuv420p", project.getProjectDirectory() + "/out.mp4"});
This command is taken from the command line example found here:
https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images
Thank you in advance for anyone taking the time to look through this post... I am pretty baffled at this point, as there are no errors I can find and no video...
Thanks

I've been messing around with it for a couple hours now and pretty much every time, i get gradle yelling at me about the fact that it can't find some file. I'm beginning to think that maybe it is because my LOCAL_LDLIBS aren't in the same order as the original...? Im not entirely sure... Does anyone else have any ideas...?
