Getting the ROOT permission for Android is as simple as executing the command "su" under Runtime.
// To obtain ROOT permissions
public void get_root(){
if (is_root()){
Toast.makeText(mCtx, " Already have ROOT permissions !", Toast.LENGTH_LONG).show();
}
else{
try{
progress_dialog = ProgressDialog.show(mCtx,
"ROOT", " Is access to ROOT permissions ...", true, false);
Runtime.getRuntime().exec("su");
}
catch (Exception e){
Toast.makeText(mCtx, " To obtain ROOT Error while permissions !", Toast.LENGTH_LONG).show();
}
}
}
Where is_root() determines whether you already have the ROOT permission. As long as one of the files /system/bin/su, /system/xbin/su exists, it indicates that it already has ROOT permissions. If neither exists, it does not have ROOT permissions.
// To determine whether or not ROOT permissions
public static boolean is_root(){
boolean res = false;
try{
if ((!new File("/system/bin/su").exists()) &&
(!new File("/system/xbin/su").exists())){
res = false;
}
else {
res = true;
};
}
catch (Exception e) {
}
return res;
