Webrtc 支持 Android 5.0

Question

我正在开发一个 webrtc 应用程序。我发现 webrtc 不支持 android 5.0 (api level 21)。这是我从 webrtc 库（libjingle）获得的代码：

  /**
   * Checks if API is supported and all cameras have better than legacy support.
   */
    public static boolean isSupported(Context context) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
            return false;
        }

        CameraManager cameraManager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
        try {
            String[] cameraIds = cameraManager.getCameraIdList();
            for (String id : cameraIds) {
                CameraCharacteristics characteristics = cameraManager.getCameraCharacteristics(id);
                if (characteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL)
        == CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY) {
                    return false;
                }
             }
             // On Android OS pre 4.4.2, a class will not load because of VerifyError     if it contains a
             // catch statement with an Exception from a newer API, even if the code is never executed.
             // https://code.google.com/p/android/issues/detail?id=209129
         } catch (/* CameraAccessException */ AndroidException e) {
             Logging.e(TAG, "Camera access exception: " + e);
             return false;
         }
        return true;
    }

它总是返回 false，因为 Android 5.0 的 INFO_SUPPORTED_HARDWARE_LEVEL 是 INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY。所以我不能使用相机来捕捉本地媒体流。

有人帮我吗？

我已经为 android 实现了 webRTC，它也支持棒棒糖和棉花糖，请查看link
