I'm launching a game on Android device and getting this error. I`m using up to date Android version, also libgdx.
The library 'jinput-platform-2.0.5-natives-linux.jar' contains native libraries that will not run on the device.
The following libraries were found:
libjinput-linux.so
libjinput-linux64.so
Please help me understand what may cause the problem.
*.so files are native assemblies that are built for a particular architecture. If those *.so files were not built for android (and it seems as if they are not given the error) they will not work.
If there isn't a version for android already built, you can try to write an android version. This other SO question may be of assistance.

There are some .so libraries and java code uses them for android.
I compile this java code within android studio to get an .aar file. I need to make binding for c# code fo Xamarin.Android using Visual Studio. So, while binding with java is working good, the java code throws exception:
java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader
Through the seeing of full exception message I got that java code can't find .so files. In the Android Studio project .so libs are settled at ./lib/armeabi-v7a/, and the java code works well.
So, the question is: where should I put .so libs in C# binding library? Some inner scent tips me I should put it somewhere -- that's the way libraries work.
I've tried to put .so libraries in directory with my .dll, also deeper in ./lib/armeabi-v7a/, but it actually didn't help -- the exception was the same. I've tried to put them in the directory with my .aar file and also in the deeper directory in ./lib/armeabi-v7a/ but this is kinda of shamanism. it's also didn't help.
the problem was in the way I tried to check the work of program. My Android emulator didn't have the armeabi-v7a support. After I tried to change my emulator settings. it became laggy and very slow. The issue was to test an application on real device.
I am struggling to put my model in the Android studio.
In order to use my model in the Android studio, I also know that I need to put the libandroid_tensorflow_inference_java.jar and libtensorflow_inference.so files into the assets folder in Android Studio.
So I used git to download the tensorflow library and use it to build .so and .jar files.
During the creation of the .so file I faced a problem that I could not solve.
I installed the SDK in the Android studio according to the procedure, and since I currently only support NDK version 17 in the studio, I installed version 12 externally and unzipped it.
~/tensorflow/WORKSPACE
In order to build a bazel, I modified the content of WORKSPACE in the root folder of tensorflow as shown above. this
But I had to face these terrible errors.
this this
To solve this problem, I changed the NDK location and installed another version of NDK. I tried to take other actions but the error did not go away. I have been working from yesterday to solve this problem. I need your help.
It looks like you're missing the -std=c++11 flag.
Try passing this additional Bazel flag: --cxxopt=-std=c++11.
This question might seem too basic but I'm struggling a lot about this stuff, please help me or guide me.
I downloaded opencv (open source computer vision) libraries and I want Android Studio to be able to use those libraries.
I checked this answer also-How to use opencv in android studio using gradle build tool?
but this answer talks about having opencv-android-sdk and nowadays I think opencv has not anything like opencv-android-sdk , so I couldn't follow that answer.
Now the main point is, what I downloaded and extracted has a folder named java , there is a opencv-320.jar file and two folder x86 and x64, x64 folder contains opencv_java320.dll file. I believe these two files are only files needed to get opencv libraries in Android Studio. But I don't know how it can be done. Please help me.
You should not be using any dll or jar file that is not specifically for Android.
OpenCV has an Android version: http://opencv.org/platforms/android/
Follow the instructions and example there in order to use it.
Two years ago I developed a Qt4 Android app using Ministro and it worked perfectly in that time. Right now I am porting the same code into Qt5. After updating several files I could compile and create the APK file in a pretty clean way.
Nevertheless, when I try to deploy the app into my tablet, it crashes showing these two error messages:
No implementation found for int[] org.qtproject.qt5.android.ExtractStyle.extractNativeChunkInfo()
And:
E/libEGL (11187): cache file failed CRC check
These are my settings:
QtCreator with Qt 5.5.1
Android Studio (Android 5.0.1 - API Level 21)
Android NDK (r10e)
Ant (1.9.6)
JDK (1.8.0_73)
Note: I tried to deploy my app from a virtual android device (using API 23) and I got the same result.
Finally I could solve the problem in a very strange way: I removed all the Android references in my code, including the android manifest.
In other words, I transformed my app into a "desktop" solution. Then, from QtCreator I made the deployment pointing to android and everything worked in a pretty clean way. I wonder how Qt solutions have evolved as an actual resource for mobile development in just few years.
I'm currently working with Aldebaran-Robotics' NAO (v3.3) and I was wondering if I can use the jNAOqi-SDK within Android to control the robot from a phone or tablet.
Using the SDK with basic java in Eclipse was pretty simple as described in this tutorial, so I tried to do this in ADT Eclipse. I imported the *.jar-file and placed the precompiled libjnaoqi.so from the package in libs/armeabi and libs/armeabi-v7a, but calling System.loadLibrary("jnaoqi") or System.loadLibrary("<jnaoqi>") resulted in the following error at runtime:
I/dalvikvm(2019): Unable to dlopen(/data/data/com.example.hellonao/lib/libjnaoqi.so): Cannot load library: link_image[1995]: failed to link libjnaoqi.so
I checked the filesystem, but the file was in the lib folder as expected, so I guess it has to be a problem with the library itself.
It's just a shot in the dark but do I have to recompile the library using ndk and naoqi?
I quickly abandoned my project but Aldebaran was busy in the meantime. I recently found a thread about it in the Aldebaran community (login required), where two employees (Nicolas Rigaud and Erwan Pinault) mention upcoming Android support.
nrigaud:
there will be a better Java SDK on our next software version. Meanwhile, it's true that it's not that easy to do Java on the robot
epinault:
In the next SDK you will have library (jar/so) for android
