adb update a non-market apk?

问题:

Is there a way we can update (not reinstall) a non-market apk on an Android device? I could only find an adb install (nothing like adb update)

回答1:

adb install -r is the closest you get, that is actually an update as it keeps the database and stored preferences. If you uninstall/re-install both the app database and preferences is deleted. What exactly are you trying to update about the app that -r option does not help you with ?

adb install -r didn't work for me. So, I did a little workaround.

1. Uninstall app but keep the data by using adb uninstall -k com.packagename. This will uninstall the app but keeps the data. See this

2. Install the app again using adb install package.here.

Note: You must have root access to execute this commands.

The easiest way to do it exactly like market apk, is to download the APK to your phone (i.e. download from Google Drive or from email) and then click on the APK in the Downloads library
