I have done many reinstalls of my OS on my Android phone in the last few months for various reasons. Every time, the biggest hassle is manually searching, downloading and installing all the apps I had in my previous installation.
I use a degoogled custom rom, downloading apps from F-Droid and Aurora Store, so no Google solutions are acceptable.
What I want, is to have a way to keep on my computer a copy of all the apks of the installed apps of my phone, and have it automatically updated too, so that when the time comes to reformat my phone and install everything all over, I will be able to simply
adb install all of the apks in no time, instead of doing it all manually and waiting for them to also be downloaded. Any suggestions for how I can make that happen with existing programs, preferably open source?
adb backup -f all -all -apk -nosystem. Then unpack using the created backup via Android backup Extractor (abe), get the APK files and delete the other file(s).
