Of course. Sorry for the late reply.
Requirements:
- LDP Android apk (preferably r23.1 but any should work)
- The www.zip file from here
- Android SDK Build Tools (preferably 24.0.3 or newer)
- Java Development Kit 8
- Uber apk signer (highly recommended but optional)
- Apktool (optional)
- ADB (optional)
- And last but not least, a brain
- Unzip the apk and www.zip
- Copy the www folder into ExtractedAPK/assets and ExtractedAPK/res , if you get asked to merge/overwrite something, you did it right
- Change package name and ID (optional):
- Decompile the apk using apktool (how to do it should be in the tool's documentation)(but use a different dir, not the one where you extracted the apk)
- Open the decopiled AndroidManifest.xml with your favourite text editor and change package="indivi.indivigames.lustdollplus" to package="indivi.indivigames.lustdollplus.extras" and android:label="@string/app_name" to android:label="Lust Doll Plus Extras"
- Build the apk with apktool
- Extract AndroidManifest.xml from the built apk (you can find the apk in DecompiledAPK/dist) and move it to ExtractedAPK
- Zip the contents of ExtractedAPK and change the zip's extension from zip to apk
- Sign the new apk (Follow the one that starts with Automated Process)
- Install the apk (preferably using ADB)
If you find instructions like "Decompile the apk using apktool" too vague, just tell me and I'll give you the step-by-step instructions. And don't lose the key you used to sign the apk.
One more thing, I found a way to move saves on Android, but it requires your phone to be rooted.
