version 2.0.1 don't work

I installed and tested version 2.0.1. It don't work correctly.
I think about the cause of the problem(and workaround) as follows.

The callback function called by xposed is inaccessible because of insufficient permissions on "Modsettings.xml".
The difference from the previous version is: /data/data/tw.fatminmin.xposed.minminguard/shared_prefs/ModSettings.xml

  • Version2.0b5: 664
  • Version2.0.1: 660

Therefore, version 2.0.1 can also be used to function by manually changing the "Modsettings.xml" permissions.

I paid attention to the following changes.
But I didn't know how to solve the problem.

  • Version2.0b5: SharedPreferences("ModSettings", MODE_WORLD_READABLE)
  • Version2.0.1: SharedPreferences("ModSettings", MODE_PRIVATE)

relevant information:

  • OS: Oreo 8.1.0 [Lineage OS 15.1(RR-OS6.0.0)]
  • Xposed: Framework: (SDK_27)-90.2-beta3_(Systemless)
  • Magisk: 16.4(1642)
  • SELinux: Permissive

You are correct. Because I was testing in the VirtualXposed which hooked apps are running in the same permission context with MinMinGuard, I did not encounter this issue.

The reason I changed MODE_WORLD_READABLE to MODE_PRIVATE is the new sdk requires it.

I thought XSharedPreferences.makeWorldReadable should solve this issue but it didn't.

I will try to find another solution or do you have any suggestion?

Thank you for your reply. 😄
I have two ideas.
a. Granting permissions from the MinminGuard process
b. Use ContentProvider

a. Granting permissions from the MinminGuard process

This is the same way as XSharedPreferences.makeWorldReadable().

for example

modPref.edit()
    .putBoolean(info.packageName, false)
    .putBoolean(Common.getWhiteListKey(info.packageName), true)
    .apply();
File modPrefFile = new File(Environment.getDataDirectory(), "data/" + getPackageName() + "/shared_prefs/" + Common.MOD_PREFS + ".xml");
modPrefFile.setReadable(true, false);

b. Use ContentProvider

There is a library created for use in xposed.
