+## Media Testing ##

+#### AMR-NB Decoder :
+The Amr-Nb Decoder Test Suite validates the amrnb decoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m AmrnbDecoderTest
+```
+
+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/AmrnbDecoderTest/AmrnbDecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/AmrnbDecoderTest/AmrnbDecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://drive.google.com/drive/folders/13cM4tAaVFrmr-zGFqaAzFBbKs75pnm9b). Push these files into device for testing.
+Download amr-nb folder and push all the files in this folder to /data/local/tmp/ on the device.
+```
+adb push amr-nb/. /data/local/tmp/
+```
+
+usage: AmrnbDecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/AmrnbDecoderTest -P /data/local/tmp/
+```

+## Media Testing ##

+#### AMR-WB Decoder :
+The Amr-Wb Decoder Test Suite validates the amrwb decoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m AmrwbDecoderTest
+```
+
+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/AmrwbDecoderTest/AmrwbDecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/AmrwbDecoderTest/AmrwbDecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://drive.google.com/drive/folders/13cM4tAaVFrmr-zGFqaAzFBbKs75pnm9b). Push these files into device for testing.
+Download amr-wb folder and push all the files in this folder to /data/local/tmp/ on the device.
+```
+adb push amr-wb/. /data/local/tmp/
+```
+
+usage: AmrwbDecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/AmrwbDecoderTest -P /data/local/tmp/
+```

+#### ID3 Test :
+The ID3 Test Suite validates the ID3 parser available in libstagefright.
+
+Run the following command in the id3 folder to build the test suite:
+```
+m ID3Test
+```
+
+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/ID3Test/ID3Test /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/ID3Test/ID3Test /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://drive.google.com/drive/folders/1pt5HFVSysbqfyqY1sVJ9MTupZKCdqjYZ). Push these files into device for testing.
+Download ID3 folder and push all the files in this folder to /data/local/tmp/ID3 on the device.
+```
+adb push ID3/. /data/local/tmp/ID3
+```
+
+usage: ID3Test -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/ID3Test -P /data/local/tmp/ID3/
