Which apk should I use on Bundle tool

Question

I use bundle tool version 1.7.0 to extract apks from bundle file (.aab) after that it gave me a toc.pb and splits folder. On splits folder there are apks base.af,base.en, base-master.apk, base-master2.apk etc. but when i try to install it on my device it says app not installed but on bluestach version 5 it work. What do you guys think I should do?

Answer 1

You shouldn't extract the APKs manually. You should use bundletool to select the APKs that are appropriate for the device.

First, you create a JSON file with the device specifications, then you pass it to the extract-apks command of bundletool.

From https://developer.android.com/studio/command-line/bundletool:

Generate and use device specification JSON files

bundletool is capable of generating an APK set that targets a device configuration specified by a JSON file. To first generate a JSON file for a connected device, run the following command:

bundletool get-device-spec --output=/tmp/device-spec.json bundletool

creates a JSON file for your device in the directory the tool is located.

[...]

You can then pass this JSON to the bundle extract-apks command, as described in the previous section.

Extract device-specific APKs from an existing APK set

If you have an existing APK set and you want to extract from it a subset of APKs that target a specific device configuration, you can use the extract-apks command and specify a device specification JSON, as follows:

bundletool extract-apks
--apks=/MyApp/my_existing_APK_set.apks
--output-dir=/MyApp/my_pixel2_APK_set.apks
--device-spec=/MyApp/bundletool/pixel2.json

Another shorter way would be to call the install-apks directly if you don't need to see the APKs before installing them.

See the Deploy to a connected device section of the documentation.
