I am trying to run my Tensorflow model on Android, so I am using the nightly native build in here and following the Android demo, I have been successfully get the Tensorflow Android lib running and loaded up the model with below code.
inferenceInterface = new TensorFlowInferenceInterface(getAssets(), MODEL_FILE);
And the log shows the results are good.
I/TensorFlowInferenceInterface: Successfully loaded TensorFlow native methods (RunStats error may be ignored)
I/TensorFlowInferenceInterface: Model load took 1007ms, TensorFlow version: 1.2.0-rc0
I/TensorFlowInferenceInterface: Successfully loaded model from 'file:///android_asset/model.pb'
However, when I finished feeding all the input nodes
inferenceInterface.feed("input1", new int[]{1, 2, 3}, 1, 3);
inferenceInterface.feed("input2", new int[]{3}, 1);
inferenceInterface.feed("input3", new int[]{4}, 1);
Then call the run method
inferenceInterface.run(new String[]{"output"});
The Tensorflow is broken saying that some kernels are not registered
E/TensorFlowInferenceInterface: Failed to run TensorFlow inference with inputs:[input1, input2, input3], outputs:[output]

I think the "LessEqual" for int32 should be defined in Tensorflow but just not built along with Tensorflow Android Lib.
So my question is how to include more kernels in the Android lib build or any other way to resolve this, any help will be much appreciated.
I recommending reading this free eBook: Building Mobile Applications with TensorFlow
It has a section on What Ops Are Available on Mobile? (page 33), which explains how to Add the implementation to the build for those op kernels which default to being stripped out for mobile builds.
FYI, the eBook is written by Pete Warden (GitHub, blog), who works at Google and is one of the maintainers of TensorFlow.

I need help, cause I'm stucked for 2 days from now and i can't find anything.
I bought device: Kcosit V720 on aliexpress and they send me library with it, but it's so hard to get it work correctly.
While I was trying to load library, i had to download libcamera_client.so, because libbarcodereader.so needed it, so i don't know if it is compatible, but now, I'm receiving another error. Any ideas how to fix it ?:

You are most likely missing another .so file. Ensure that all .so files are in the same directory.
The following may help to identify referenced .so files:

Update:
I'm not aware of any android API for this type of hardware. According to https://kcosit.com/kcosit-v720-p1496437.html your device contains most likely a OEM version of the SE4710 barcode scanner, manufactured by Motorola. It seems that there exists an SDK from Motorola but I could only find the corresponding documenation. It is most likely used as base for SDKs provided by OEM licensors. One of such an SDK is available here: https://developer.zebra.com/community/tools
Maybe you are lucky and you can use this SDK also for your device. If it should
also be compatible with your device you would of course also need to check license of the SDK - I haven't found any info yet. Maybe you are able to find a source for the original SDK from Motorolla or an other SDK from an OEM licensor.
I am trying to integrate Symmetric-Android 3.10.2 in my Android application. It is showing

It sounds like your issue may not be related to SymmetricDS, but instead how your classpath is configured in this Android project. There are several solutions in this thread that might help

i added the libpthread.so.0 file to my jnilibs (all subfolders) but the result is same.
please give me a hint to solve this problem
There is no libpthread.so on Android, all threading functions are handled by libc itself. It seems the RxTx library does not support the Android platform.
You can try porting it yourself or use another solution:
Android Things API
Android USB Host API
RxTx Android port (warning: last update 2011)
android-serialport-api (warning: last update 2011)
usb-serial-for-android (last update 2016)
I am trying to use Chrome Custom Tabs in my Android application. My MainActivity class extends AppCompatActivity. In onCreate, I invoke startCustomTabs. Below is the code for that:
private void startCustomTab(){
CustomTabsIntent intent = new CustomTabsIntent.Builder().setToolbarColor(getResources().getColor(R.color.colorPrimary)).build();
intent.launchUrl(this, Uri.parse("http://github.com/black-dragon/SaavnExtractor"));
}
As soon as the app launches, it crashes with following the error:

Note: If I execute the same code with the same methods in a new app, the Custom Tabs launch fine.
Okay, so here is the resolution. I was using build tools version 25.0.0 but my SDK platform was 24.
Update the build tools, platform tools & SDK to same version and then you won't face this issue.
Along with #Nick's answer, I also had to update the Facebook SDK version and the crash stopped happening.
You need to add Customtabs dependency in your build.gradle file.
implementation 'com.android.support:customtabs:28.0.0'
Suddenly started receiving this error since a support library update, which crashes the application on launch, even if everything builds fine. I tried to use lower version packages, which gave me the same error. I tried complete reinstall of Xamarin and Android SDK and finally creating a new Project which uses AppCompat but no success.
