android - Youtube Watch Me Android 应用程序意外关闭

Question

我从 https://github.com/youtube/yt-watchme 创建安卓应用程序.

当我尝试使用“CREATE LIVE EVENT”按钮创建 Activity 时。它引发了一些以下错误。我认为这是由于相机权限问题导致的。

错误:

09-17 11:43:53.582  32383-32383/com.google.android.apps.watchme E/AndroidRuntime﹕ FATAL EXCEPTION: main

            at dalvik.system.NativeStart.main(Native Method)

任何人请建议。我该如何解决这个问题。

提前致谢

Answer 1

在调用发生的 Activity 代码中，用支票将其包装起来:

int hasCamPermission = checkSelfPermission(cameraPermission);
int hasMicPermission = checkSelfPermission(microphonePermission);

首先在StreamerActivity中添加如下方法:

private boolean shouldCheckForPermission() {
  return Build.VERSION.SDK_INT >= Build.VERSION_CODES.M;
}

将这些行更改为:

int hasCamPermission = shouldCheckForPermission() ? checkSelfPermission(cameraPermission) : PackageManager.PERMISSION_GRANTED;
int hasMicPermission = shouldCheckForPermission() ? checkSelfPermission(microphonePermission) : PackageManager.PERMISSION_GRANTED;

为此，您需要使用 SDK 23 进行编译和定位，如我在上面的回答中所述。
