Token authentication Android Studio

If I want to store the token retrieved from the server in a place where i can access to it from wherever in my code to keep sending it as a json header to my server, where i should store it? is there any other recommendation you can give me to use with token auth?

It seems safe to store it in the app's private SharedPreferences and make a static helper to get it. Only your app will have access to this.

from Android API documentation

File creation mode: the default mode, where the created file can only be accessed by the calling application (or all applications sharing the same user ID).

package net.rouk1.helper;

import android.content.Context;
import android.content.SharedPreferences;

public class TokenSaver {
    private final static String SHARED_PREF_NAME = "net.rouk1.SHARED_PREF_NAME";
    private final static String TOKEN_KEY = "net.rouk1.TOKEN_KEY";

    public static String getToken(Context c) {
        SharedPreferences prefs = c.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
        return prefs.getString(TOKEN_KEY, "");
    }

    public static void setToken(Context c, String token) {
        SharedPreferences prefs = c.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = prefs.edit();
        editor.putString(TOKEN_KEY, token);
        editor.apply();
    }

}
