New features

SafetyNet / DroidGuard

The updated SafetyNet implementation runs proprietary DroidGuard code privileged in the com.google.android.gms package name. This is required on at least some devices to pass SafetyNet. However this features is disabled by default. If you don't want to run proprietary code by Google on your device do not enabled SafetyNet.

As of now, microG SafetyNet implementation, once enabled, should work on all devices and ROMs that would pass SafetyNet attestation with original Google Play Services. This means that ROMs that are rooted (= come with a su binary that allow privilege escalation), with unlocked bootloader, or for some other reason do not pass the CTS or trigger the SafetyNet system will fail SafetyNet attestation. Hiding or spoofing such details from DroidGuard/SafetyNet is out of scope for this project, but techniques to allow passing SafetyNet on custom ROMs should equally work with microG.

Device profiles

This features is mostly useful for Huawei devices or other devices that are banned from accessing Google services. Choosing a profile of a non-banned device should allow using the device with Google services.

For now, two device profiles are included with microG (Nexus 5X with Android 8.1.0 and Moto G with LineageOS 14.1).

If you are a developer, you can easily create a device profiles based on data gathered from a device. See this file for a sample device profile. Once created, you can import device profiles in microG settings (under "Device registration") to test the profile.

If you are a custom ROM developer, you can add a custom device profile for your ROM by placing an appropriate device profile in /system/etc/microg_device_profile.xml. This can be useful to spoof the details of the original vendor ROM.

v0.2.22.212658

Maintenance release with a few bug fixes.

See: commits since v0.2.21.212158

v0.2.21.212158

This release fixes two major bugs introduced with v0.2.20.212158.

Notice regarding updates from v0.2.20.212158

If you already updated to v0.2.20.212158 and you can't install the update to v0.2.21.212158 the usual way, you may need to connect your device to a compute with adb installed and invoke the following commands in a shell:

adb push path/to/play-services-core-212158042.apk /data/local/tmp/play-services-core-212158042.apk
adb shell pm install-create -r --staged # This returns a session id in brackets
adb shell pm install-write *session-id* base /data/local/tmp/play-services-core-212158042.apk
adb shell pm install-commit *session-id*
adb shell rm /data/local/tmp/play-services-core-212158042.apk
adb reboot

If this doesn't work, you might need to directly update the .apk on your /system-partition or wait for the ROM developer to update to v0.2.21.212158.
