# TF Lite Android App
|
||||
|
||||
## Building from Source with Bazel
|
||||
|
||||
1. Follow the [Bazel steps for the TF Demo App](https://github.com/tensorflow/tensorflow/tree/master/tensorflow/examples/android#bazel):
|
||||
|
||||
1. [Install Bazel and Android Prerequisites](https://github.com/tensorflow/tensorflow/tree/master/tensorflow/examples/android#install-bazel-and-android-prerequisites).
|
||||
It's easiest with Android Studio.
|
||||
|
||||
- You'll need at least SDK version 23.
|
||||
- Bazel requires Android Build Tools `26.0.1` or higher.
|
||||
- You also need to install the Android Support Repository, available
|
||||
through Android Studio under `Android SDK Manager -> SDK Tools ->
|
||||
Android Support Repository`.
|
||||
|
||||
2. [Edit your `WORKSPACE`](https://github.com/tensorflow/tensorflow/tree/master/tensorflow/examples/android#edit-workspace)
|
||||
to add SDK and NDK targets.
|
||||
|
||||
- Make sure the `api_level` in `WORKSPACE` is set to an SDK version that
|
||||
you have installed.
|
||||
- By default, Android Studio will install the SDK to `~/Android/Sdk` and
|
||||
the NDK to `~/Android/Sdk/ndk-bundle`.
|
||||
|
||||
2. Build the app with Bazel. The demo needs C++11:
|
||||
|
||||
```shell
|
||||
bazel build -c opt --cxxopt='--std=c++11' \
|
||||
//tensorflow/contrib/lite/java/demo/app/src/main:TfLiteCameraDemo
|
||||
```
|
||||
|
||||
3. Install the demo on a
|
||||
[debug-enabled device](https://github.com/tensorflow/tensorflow/tree/master/tensorflow/examples/android#install):
|
||||
|
||||
```shell
|
||||
adb install bazel-bin/tensorflow/contrib/lite/java/demo/app/src/main/TfLiteCameraDemo.apk
|
||||
```
