How can i get root permission only for application

Question

Is it possible to get root access for only one application? the idea behind is to i did't want to open permission dialog for accessing some feature of application like storage permission like vise.

is it possible via running command Runtime, but i am not sure this is working or not for android 14 OS device.

Process root = Runtime.getRuntime().exec("su");

Also getting FACTORY_TEST permission from google document but this will not help me.

Answer 1

As You Have Marked Code

Process root = Runtime.getRuntime().exec("su");

This code will also work in android-14 but it is not a good way.

Instead You can use the libsu by topjohnwu (magisk-official)

Here you can find it topjohnwu/libsu

It will work like a charm on every android

Hope it Helps.
