Android device compatibility with OS and Other
- 1.
- 2. Why is Androidversion compatibility essential for your device? To receive the latest Android device updates, it must meet the specified requirements of the corresponding Android OS framework versions. Interoperability: It ensures that different components within the Android ecosystem, such as hardware, software, and apps, can work seamlessly together. The Vendor Interface (VINTF) Object in the Android Open Source Project is a key component that helps keep the Android OS and the device-specific changes together so they can work properly.
- 3. How to alignAndroid OS framework with device-specific implementation? Match device and framework manifests and matrices for compatible updates. Manifests describe what's provided; matrices detail requirements.
- 4. Device HAL versionand Framework manifest The framework manifest describes high-level services the framework can provide to the device. Vendor has to implement HAL compatible to Android OS framework version. Example : To elevate your device to FCM level 4, vendors are required to seamlessly integrate the upgraded thermal HAL, transitioning from version 1.x to the all-new 2.0, as introduced in AOSP version 10/Q.
- 5. How to updatedevice manifest ? Specify the desired FCM version by declaring it as the 'target-level' attribute in the top-level <manifest> element in the device manifest. Path of device manifest device/VENDOR/DEVICE/manifest.
- 6. To create aperfect match between a device manifest and a framework compatibility matrix, ensure that manifest.target-level matches compatibility-matrix.level precisely, or else, no match occurs. The list of released FCM versions can be found under hardware/interfaces/compatibility_matrices
