In the next method, you can use an adb command to get package deal names and their IDs. Operate the command beneath to do so.

$ adb shell pm list deals -f | awk ‘print $NF’ FS=/

You will get some output like this:

SamsungCamera.apk=com.sec.android.application.digital camera

SamsungMagnifier3.apk=com.sec.android.app.magnifier

foundation.apk=org.mozilla.firefox

The still left hand side in every line in the output will give you a trace about the application name, whilst the right hand side (following “=” symbol) will give you package ID. You can also make use of the “grep” command to quickly come across your desired package ID.

$ adb shell pm listing packages -f | awk ‘print $NF’ FS=/ | grep vlc

Run Backup Command

Now that your Android machine is linked to your Linux Personal computer, authenticated to an ADB connection and you have a deal ID, you are ready to consider software backup. To do so, run a command in the following structure:

$ adb backup -apk <package_id>

$ adb backup -f vlc_backup.ab -apk org.videolan.vlc

Caveat

When the method stated higher than should really function with most 3rd celebration Android applications, certain Android apps, specifically pre-set up program apps, do not allow having backups of application knowledge by means of the “adb” command.

$ java -jar abe.jar unpack backup.ab backup.tar <password_you_entered_during_backup>

Exchange the file names as required. In the final aspect of the command, provide the password in simple textual content. Right here is an case in point of the command:

$ java -jar abe.jar unpack vlc_backup.ab backup.tar 1234

You can now freely examine the “.tar” file and extract the info to look through the backup documents.

Summary
