-<p>The LoWPAN APIs provide a means by which applications can communicate

-  <li>TBD</li>

-
-<p class="note"><strong>Note:</strong> Not all Android-powered devices provide LoWPAN functionality.
-If your application uses these APIs, declare so with a <a

-# LoWPAN Unit Tests
-This package contains unit tests for the android LoWPAN framework System APIs based on the
-[Android Testing Support Library](http://developer.android.com/tools/testing-support-library/index.html).
-The test cases are built using the [JUnit](http://junit.org/) and [Mockito](http://mockito.org/)
-libraries.
-
-## Running Tests
-The easiest way to run tests is simply run
-
-```
-frameworks/base/lowpan/tests/runtests.sh
-```
-
-`runtests.sh` will build the test project and all of its dependencies and push the APK to the
-connected device. It will then run the tests on the device.
-
-To pick up changes in framework/base, you will need to:
-1. rebuild the framework library 'make -j32'
-2. sync over the updated library to the device 'adb sync'
-3. restart framework on the device 'adb shell stop' then 'adb shell start'
-
-To enable syncing data to the device for first time after clean reflash:
-1. adb disable-verity
-2. adb reboot
-3. adb remount
-
-See below for a few example of options to limit which tests are run.
-See the
-[AndroidJUnitRunner Documentation](https://developer.android.com/reference/android/support/test/runner/AndroidJUnitRunner.html)
-for more details on the supported options.
-
-```
-runtests.sh -e package android.net.lowpan
-runtests.sh -e class android.net.lowpan.LowpanManagerTest
-```
-
-If you manually build and push the test APK to the device you can run tests using
-
-```
-adb shell am instrument -w 'android.net.wifi.test/androidx.test.runner.AndroidJUnitRunner'
-```
-
-## Adding Tests
-Tests can be added by adding classes to the src directory. JUnit4 style test cases can
-be written by simply annotating test methods with `org.junit.Test`.
-
-## Debugging Tests
-If you are trying to debug why tests are not doing what you expected, you can add android log
-statements and use logcat to view them. The beginning and end of every tests is automatically logged
-with the tag `TestRunner`.
