I'm trying to simply install a multi-apk app on my non-rooted Samsung tablet via ADB, I think I'm not doing something right.
I first made sure my device was connected/authorized when using ADB. Then, I successfully pushed the apks to /sdcard/:
adb push E:\PopupFactory2\. /sdcard/
Then, I tried installing using -r and -d switches (to install an older version of an existing app on my tablet without deleting it's respective appdata).. which produces an error:
adb shell pm install-multiple -r -d /sdcard/com.rhyshan.popupfactory2.apk /sdcard/config.en.apk
Unknown command: install-multiple
I know install-multiple is a valid command for my ADB runtime; as its listed in the help text when I just type "ADB". Is my syntax wrong? Everything I read online suggests I'm using the right syntax.
Is there a better way for me to downgrade an existing app (with multiple apk's) to an older version without deleting its respective appdata? I also have a packaged apkx as well.
