TF Mobile in Android apps

The TensorFlow ecosystem enables it to be used in Android apps through the interface class  TensorFlowInferenceInterface, and the TensorFlow Java API in the jar file libandroid_tensorflow_inference_java.jar. You can either use the jar file from the JCenter, download a precompiled jar from ci.tensorflow.org, or build it yourself.

The inference interface has been made available as a JCenter package and can be included in the Android project by adding the following code to the build.gradle file:

allprojects {
   repositories {
      jcenter()
   }
}
dependencies {
   compile 'org.tensorflow:tensorflow-android:+'
}

Note

Instead of using the pre-built binaries from the JCenter, you can also build them yourself using Bazel or Cmake by following the instructions at this link: https://github.com/tensorflow/tensorflow/blob/r1.4/tensorflow/contrib/android/README.md.

Once the TF library is configured in your Android project, you can call the TF model with the following four steps...
