LiteRT is the new name for TensorFlow Lite (TFLite). While the name is new, it's still the same trusted, high-performance runtime for on-device AI, now with an expanded vision.

Describe the problem

Describe the problem clearly here. Be sure to convey here why it's a bug in TensorFlow or a feature request.

Source code / logs

Include any logs or source code that would be helpful to diagnose the problem. If including tracebacks, please include the full traceback. Large logs and files should be attached. Try to provide a reproducible test case that is the bare minimum necessary to generate the problem.

Steps to reproduce:

  1. Create a new Android project.
  2. Add TensorFlow Lite dependencies: 
    implementation("org.tensorflow:tensorflow-lite:2.14.0")
implementation("org.tensorflow:tensorflow-lite-support:0.4.3")
  3. Download BlazeFace tflite model and add to src/main/assets folder
  4. Initialise Tensorflow Lite Interpreter in onCreate() of MainActivity: 
        val model = FileUtil.loadMappedFile(this, "blaze_face_short_range.tflite")
    val options = Interpreter.Options()
    options.numThreads = 4
    val interpreter = Interpreter(model, options)
  5. Run the app on any Android Emulator using API Level between 21 and 25 included.
  6. App crashes with the following error: 
    E  FATAL EXCEPTION: main
Process: com.example.myapplication, PID: 8645
java.lang.UnsatisfiedLinkError: Failed to load native TensorFlow Lite methods. Check that the correct native libraries are present, and, if using a custom native library, have been properly loaded via System.loadLibrary():
