However, if you prefer using MediaPipe without\nAndroid Studio, please run\n[`setup_android_sdk_and_ndk.sh`](https://github.com/google/mediapipe/blob/master/setup_android_sdk_and_ndk.sh)\nto download and setup Android SDK and NDK before building any Android example\napps.\n\nIf Android SDK and NDK are already installed (e.g., by Android Studio), set\n`$ANDROID_HOME` and `$ANDROID_NDK_HOME` to point to the installed SDK and NDK. \n\n export ANDROID_HOME=\u003cpath to the Android SDK\u003e\n export ANDROID_NDK_HOME=\u003cpath to the Android NDK\u003e\n\nand add `android_ndk_repository()`, `android_sdk_repository()` and `bind()`\nrules into the\n[`WORKSPACE`](https://github.com/google/mediapipe/blob/master/WORKSPACE) file as\nthe following: \n\n $ echo \"android_sdk_repository(name = \\\"androidsdk\\\")\" \u003e\u003e WORKSPACE\n $ echo \"android_ndk_repository(name = \\\"androidndk\\\", api_level=26)\" \u003e\u003e WORKSPACE\n $ echo \"bind(name = \\\"android/crosstool\\\", actual = \\\"@androidndk//:toolchain\\\")\" \u003e\u003e WORKSPACE\n\nIn order to use Framework on earlier Android versions, MediaPipe needs to switch\nto a lower Android API level. You can achieve this by specifying `api_level =\n$YOUR_INTENDED_API_LEVEL` in android_ndk_repository() and/or\nandroid_sdk_repository() in the\n[`WORKSPACE`](https://github.com/google/mediapipe/blob/master/WORKSPACE) file.\n| **Tip:** You can run this [script](https://github.com/google/mediapipe/blob/master/build_android_examples.sh) to build (and install) all MediaPipe Android example apps.\n\n1. To build an Android example app, build against the corresponding\n `android_binary` build target. For instance, for MediaPipe Hands the target\n is `handtrackinggpu` in the\n [BUILD](https://github.com/google/mediapipe/tree/master/mediapipe/examples/android/src/java/com/google/mediapipe/apps/handtrackinggpu/BUILD)\n file:\n\n **Note:** To reduce the binary size, consider appending `--linkopt=\"-s\"` to the command below to strip symbols. \n\n bazel build -c opt --config=android_arm64 mediapipe/examples/android/src/java/com/google/mediapipe/apps/handtrackinggpu:handtrackinggpu\n\n2. Install it on a device with:\n\n adb install bazel-bin/mediapipe/examples/android/src/java/com/google/mediapipe/apps/handtrackinggpu/handtrackinggpu.apk"]]
