+#### Writer :
+The Writer Test Suite validates the writers available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+mmm frameworks/av/media/libstagefright/tests/writer/
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+
+adb push ${OUT}/data/nativetest64/writerTest/writerTest /data/local/tmp/
+
+To test 32-bit binary push binaries from nativetest.
+
+adb push ${OUT}/data/nativetest/writerTest/writerTest /data/local/tmp/
+
+The resource file for the tests is taken from Codec2 VTS resource folder. Push these files into device for testing.
+```
+adb push  $ANDROID_BUILD_TOP/frameworks/av/media/codec2/hidl/1.0/vts/functional/res /sdcard/
+```
+
+usage: writerTest -P \<path_to_res_folder\>
+```
