bundletool build-apks `--connected-device` or `--device-spec` flag/parameter are not working

Describe the bug I’ve referred Google IO’18 official session youtube video: https://youtu.be/bViNOUeFuiQ?t=1324 and it says that you can generate the apk set archive for the connected device from the app bundle during testing phase.

I’m trying to run the following command which should generate the apk set for connected device or as per the device-specs. These both commands are not working and giving me the following error.

bundletool build-apks --bundle=app/build/outputs/bundle/debug/bundle.aab --output=my_app.apks --connected-device bundletool build-apks --bundle=app/build/outputs/bundle/debug/bundle.aab --output=my_app.apks --device-spec=pixel2.json

Bundletool version(s) affected Version: [e.g. 0.3.3]

To Reproduce Steps to reproduce the behavior.

• Use the above-mentioned command to install the application to the connected device.

bundletool build-apks --bundle=app/build/outputs/bundle/debug/bundle.aab --output=my_app.apks --connected-device

Expected behavior It should generate the apk archive set for the connected device or as per the device spec json file.

Known workaround Don’t know

Environment: OS: MAC, High Sierra 10.13.4 Device : Pixel2 XL

@rksinghj4 For the first error, did you set the ADB path? If not then set it or use the full absolute path of adb. for the second error, I think there is a problem with --, make sure you’ve written the correct command. copy-paste sometimes creates the problem.

after merging those 4.

As I explained, there is no merging involved. The 4 APKs are served and installed on the device as is.

Those 4 APKs should be installed together (using “adb install-multiple”) for the app to work. The command “install-apks” from bundletool will do that automatically.

For your investigation purposes, I would suggest to seek help on a different forum, such as stackoverflow with the tag #androidappbundle

@plecesne https://github.com/plecesne thanks. That’s it? Is it final to consider the total size of the 4 apks as a benchmark? I thought there must be different size after merging of those 4.

Is it possible to install one by one those 4 apks?
