XSharedPreferences issue with Target API 28

[BytesReverser]

Hi guys i know the issue is Xsharedpreferences even if you set permissions to 777 the xposed cant read the file when the app is compiled with api 28 maybe due to recent selinux changes but if you use target api 27 or below ,the xposed can hook and read preferences properly maybe backward compatibility.

Any guys get to work around this in their xposed modules?

I possible fix i know is that moving the preferences to /data/folder/prefs.xml then it can read

no, api 28 introduced a new SELinux permission
makeworldreadable or 777 is useless

one sulotion is use api 27 or lower

or set SELinux to Permissive(not recommended)

Maybe you can use other methods such as ContentProvider, or put it to sdcard?

use this code on initzygote

      final File a = new File("/data/user_de/0/packagename/shared_prefs/prefs.xml");
        final File b = new File("/data/user/0/packagename/shared_prefs/prefs.xml");
        final File c = new File("/data/data/packagename/shared_prefs/prefs");
        File file;
        int sdk = Build.VERSION.SDK_INT;
        if (sdk == 23) {
            file = a;
        } else if (sdk < 23) {
            file = b;
        } else {
            file = c;
        }
        myPref = new XSharedPreferences(file);
        myPref.makeWorldReadable();
        myPref.reload();
        if (myPref == null) {
            myPref = new XSharedPreferences(BuildConfig.APPLICATION_ID, xmlPrefs);
            myPref = new XSharedPreferences(file);
        }
        myPref.makeWorldReadable();
        myPref.reload();
