+1. Build nplb library
+
+    ```sh
+    ninja -C out/evergreen-arm-softfp_devel nplb_install
+    ```
+
+1. Generate apk output folder

+
+### Build and run nplb test apk
+
+1. Build nplb apk
+
+    ```sh
+    ninja -C out/android-arm_devel nplb_evergreen_loader_install
+    ```
+
+1. Check the output apk file. The output file is available at
+
+    ```sh
+    out/android-arm_devel/nplb_evergreen_loader.apk
+    ```
+
+1. To run the nplb test, execute following command
+
+    ```sh
+    # install the apk
+    adb install out/android-arm_devel/nplb_evergreen_loader.apk
+
+    # launch the apk
+    adb shell "am start --esa args '--evergreen_library=app/cobalt/lib/libnplb.so,--evergreen_content=app/cobalt/content' dev.cobalt.coat"
+    ```
+
+1. Generate test result with XML format
+
+    Due to access permission constrains on AOSP, the xml file should be created
+    by `adb shell` first, before nplb apk writing test result in it.
+
+    ```sh
+    # create a file in a folder with read/write permission
+    adb shell "mkdir -p /data/local/tmp/"
+    adb shell "touch /data/local/tmp/nplb_testResult.xml"
+
+    # Make the file writable
+    adb shell "chmod a+w /data/local/tmp/nplb_testResult.xml"
+
+    # test and output to xml file
+    adb shell "am start --esa args '--evergreen_library=app/cobalt/lib/libnplb.so,--evergreen_content=app/cobalt/content,--gtest_output=xml:/data/local/tmp/nplb_testResult.xml' dev.cobalt.coat"
+    ```
+
+### Build and run nplb evergreen compat test apk
+
+1. Build nplb_evergreen_compat_tests apk
+
+    **NOTE:** Please finish nplb build in previous step before building nplb compat test
+
+    ```sh
+    ninja -C out/android-arm_devel nplb_evergreen_compat_tests_install
+    ```
+
+1. Check the output apk file. The output file is available at
+
+    ```sh
+    out/android-arm_devel/nplb_evergreen_compat_tests.apk
+    ```
+
+1. To run the nplb compat test, execute following command
+
+    ```sh
+    # install the apk
+    adb install out/android-arm_devel/nplb_evergreen_compat_tests.apk
+
+    # launch the apk
+    adb shell am start dev.cobalt.coat
