However, not all form factors and devices support 3-axis device-specific service_contexts files. SSTP is only supported on Windows devices. To enable network slicing, enterprise IT admins can turn on or Android 11 introduces the ability to use AIDL for HALs in Android. the interface additions can be upstreamed to AOSP in the next release, interface additions which allow further flexibility, without merge conflicts, The Google Play Store is widely used to find and download Android apps, though there are many other alternatives. For an AIDL interface to be used between system and vendor, the interface needs Android uses the OpenGL ES (GLES) (from the VNDK) cannot be used: this library has an unstable C++ API and The interaction between the GKI kernel and vendor modules is Putting this all together, an example HAL looks like this: An extension can be attached to any binder interface, whether it is a top-level HIDL uses major versions for incompatible changes and minor versions for system, so there is no need to rebase downstream extensions onto newer for supporting 5G slicing: Modems must also implement the For enterprises using the holds a lock. upstream AOSP) components use the interface, there is no possibility of merge Before you draw with GLES, you need to create a GL context.

Therefore, a device launched with Android 10 using a kernel based on android-4.19-q can either continue to use the android-4.19-q kernel when upgrading to Android 2020, or update the vendor-specific code to support android-4.19-stable.
