Android OS Version Compatibility

Android 13 and Above Compatibility Adaptation Guide​

Google released Android 13 and API Level 33 framework in Q3 2022.

RC's IMLib/IMKit SDK has been adapted for Android 13 in development version 5.3.0 and stable version 5.1.9.5, but some features may require modifications to your app. Below are the affected items:

  1. To ensure proper push notification functionality, use manufacturer push SDKs that have been adapted for Android 13 with the following minimum versions:

    • Xiaomi Push SDK: v5.1.0+
    • Huawei Push SDK: v6.7.0.300+
    • OPPO Push SDK: v3.1.0+
    • vivo Push SDK (official Android 13 adaptation not yet available): v3.0.0.4+

  2. Android 13 introduces new push notification permissions. The RC SDK does not request these permissions internally - your app must request them explicitly.

  3. For users integrating IMKit via source code, modify compileSdkVersion to 33; otherwise compilation will fail.
