Gmscore: com.android.vending keeps crashing

[farfromrefug]

I am running:

• LOS 16 without signature spoofing
• Magisk
• Riru to get XPosed
• FakeGApps xposed module to get signature spoofing
• install MicroG, Google play store modified from F-droid (using microg repo and nanodroid)
• use Magisk App Systemizer module to have MicroG and the play store moved to priv-app
• ensure the play store have android.permission.FAKE_PACKAGE_SIGNATURE

Now the Play Store keep on crashing with this error:

I remember having this one once but i dont remember how to fix this :s

As anyone any idea?

Looks like you need to give playstore app some permissions.

[Nanolx]

It's not enough to move priviledged apps (priv-app) into /system. You also need to do priv-app permission whitelisting, see:

https://source.android.com/devices/tech/config/perms-whitelist

tl;dr: use an installer like @ale5000-git unofficial microG installer or my NanoDroid, for the latter be sure to read it's documentation.

@Nanolx Thanks for the explanations! permissions whitelisting cant be done with magisk?

[Nanolx]

If you write the correct XML file on your own and place it into the module, then yes.

The problem is, that all those systemizers don't do priv-app permission whitelisting, so they don't actually work for priv-apps.

[farfromrefug]

@Nanolx actually it seems like they do!

Will check those file on my system. Thanks!
