Using apkanalyzer it is possible to find out a multitude of properties from a generated APK / AAB, such as file size, compare with another APK to get the file size delta, etc.

Using this tool I have created several Gradle tasks to:

• get specific dependencies sizes, and sum them to gain insight how big a SDK is;
• get download size of APK, using apkanalyzer;
• get comparative file size of APK, using apkanalyzer, comparatively to an empty app to gain insight of SDK size;

Now, what I really need is to find out is actual install size of an APK. Meaning the storage amount the APK takes once installed on a device. I have found that apkanalyzer does not provide a solution for this, and don't have the knowledge how to approach this. I don't want to do this manually, but rather has to be automated. Preferably via a Gradle task.

So: how to automate calculating the INSTALL size of an APK preferably using Gradle?

I have developed my own answer.

1. Create an AVD using e.g.: echo no | avdmanager create avd -n <name> -k "system-images;android-30;google_apis;x86" -f
2. Run AVD: emulator -avd <name>
3. Be sure to run adbd in root: adb root. This is important to retrieve package information.
4. Install APK on AVD: adb push <absolute_path_to_apk>
5. Get code path of installed APK: echo $(cut -d "=" -f2- <<< $(adb shell dumpsys package $packageName | grep codePath))
6. Use code path value from step 5 to get install size from APK: adb shell du ${codePath} -h | awk 'FNR == 3' | head -n1 | awk '{print $1;}' This returns a string value representing the install size of APK on reference device in Mb.
