I need to get root access for rooted devices, and I was wondering how I can request root access. I need the access for the file system. Thanks a lot.
In most versions of Android, that goes like this: Head to Settings, tap Security, scroll down to Unknown Sources and toggle the switch to the on position. Now you can install KingoRoot. Then run the app, tap One Click Root, and cross your fingers. If all goes well, your device should be rooted within about 60 seconds.
Just exec the command su
and within that Process
you have root priviliges:
Process p = Runtime.getRuntime().exec("su");
See this blog post for full example.
Most root devices use Superuser or SuperSU, if you wanna root ability in your app, you should claim superuser permission in your app manifest.
<uses-permission android:name="android.permission.ACCESS_SUPERUSER" />
More detailed information, you should check HOW-To SU by Chainfire (The author of SuperSU) and look into the example source libsuperuser(https://github.com/Chainfire/libsuperuser)
