How to update APK files and DM files in the res folder

The source code of the test app is in ../app/SplitApp. After updating the source code, you need to update the APK files and DM files in the res folder.

Updating APK files

1. Build the APK from source.

   m CtsDexMetadataSplitApp
   

2. Copy the APK to the res folder.

   cp \
     $ANDROID_BUILD_TOP/out/host/linux-x86/cts/android-cts/testcases/CtsDexMetadataSplitApp/x86_64/CtsDexMetadataSplitApp.apk \
     res/CtsDexMetadataSplitApp.apk
   

   Note: You may need to replace x86_64 with a different ISA, depending on the product that you lunch-ed.

3. Repeat the steps above for the split APK (CtsDexMetadataSplitAppFeatureA).

Updating DM files

The DM files contain profiles, whose headers have the dex checksums that need to match the dex files in the APKs. Therefore, after updating the APKs, you must update the DM files.

1. Create a binary profile from the text profile.

   profman \
     --create-profile-from=res/CtsDexMetadataSplitApp.prof.txt \
     --apk=res/CtsDexMetadataSplitApp.apk \
     --dex-location=base.apk \
     --reference-profile-file=/tmp/primary.prof \
     --output-profile-type=app
   

   Note: --dex-location must be set to base.apk, regardless of the actual APK name.

   Note: --reference-profile-file is the output. You can specify a different output location, but the filename must be primary.prof.

   Tip: If profman is not found, run m profman.

2. Delete the existing DM file and create the DM file from the binary profile.

   rm res/CtsDexMetadataSplitApp.dm
   zip -j res/CtsDexMetadataSplitApp.dm /tmp/primary.prof
   

3. Repeat the steps above for the split APK (CtsDexMetadataSplitAppFeatureA).
