How To Check If Android Phone Is Rooted?

I want to programatically find in my application if the android phone is rooted. I found many links like: Determine if running on a rooted device Effective way to programatically

Solution 1:

I've wrapped this code (working ok without any other external jar/lib) from RootTools

privatestaticbooleanisRooted() {
    returnfindBinary("su");
}



publicstaticbooleanfindBinary(String binaryName) {
    boolean found = false;
    if (!found) {
        String[] places = {"/sbin/", "/system/bin/", "/system/xbin/", "/data/local/xbin/",
                "/data/local/bin/", "/system/sd/xbin/", "/system/bin/failsafe/", "/data/local/"};
        for (String where : places) {
            if ( newFile( where + binaryName ).exists() ) {
                found = true;
                break;
            }
        }
    }
    return found;
}

Solution 2:

You can use the roottools library. They offer a method to check for root access. https://code.google.com/p/roottools/
