Using "adb backup" to back up an application programmatically

I am currently backing up my app with a command adb backup

when my device connects to my computer via a micro usb cable. The command looks like this:

adb backup -f Backups/app.ab -noapk com.me.app

Which outputs and an android (ab) backup file called app.ab in my Backups folder.

I am wondering if it is possible to programmatically back up an application to an SD card? I just need to periodically back up the application and its databases.

Any links / docs on this would be helpful.

Thanks, Matt

You cannot run commands ADB

(for example backup

) from your application, but you can run commands SHELL

(commands LINUX

that run from within SHELL

), for example:

Process process = Runtime.getRuntime().exec("my_command");

If you know the target and target folders, you can use the command cp

to copy files. If you want to read the results of your commands use



BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));

Make sure your app has the appropriate permissions to write to SD

.
