TensorFlow-Android-Inference

This directory contains CMake support for building the Android Java Inference interface to the TensorFlow native APIs.

See tensorflow/contrib/android for more details about the library, and instructions for building with Bazel.

Usage

Add TensorFlow-Android-Inference as a dependency of your Android application

• settings.gradle

include ':TensorFlow-Android-Inference'
findProject(":TensorFlow-Android-Inference").projectDir =
            new File("${/path/to/tensorflow_repo}/contrib/android/cmake")

• application's build.gradle (adding dependency):

debugCompile project(path: ':tensorflow_inference', configuration: 'debug')
releaseCompile project(path: ':tensorflow_inference', configuration: 'release')

Note: this makes native code in the lib traceable from your app.

Dependencies

TensorFlow-Android-Inference depends on the TensorFlow static libs already built in your local TensorFlow repo directory. For Linux/Mac OS, build_all_android.sh is used in build.gradle to build it. It DOES take time to build the core libs; so, by default, it is commented out to avoid confusion (otherwise Android Studio would appear to hang during opening the project). To enable it, refer to the comment in

• build.gradle

Output

• TensorFlow-Inference-debug.aar
• TensorFlow-Inference-release.aar

File libtensorflow_inference.so should be packed under jni/${ANDROID_ABI}/ in the above aar, and it is transparent to the app as it will access them via equivalent java APIs.
