android - Android 6.0如何获取runtimepermission

Question

我正在使用方法 YouTubeIntents.createUploadIntent 并得到下面的异常，

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.google.android.youtube/com.google.android.apps.youtube.app.honeycomb.Shell$UploadActivity}: java.lang.SecurityException: Uid 10075 does not have permission to uri 0 @ content://media/external/video/media/7757

此异常表示 youtube 应用程序没有权限 READ_EXTERNAL_STORAGE。

如何处理这个异常？

Answer 1

这就是你应该做的。

 if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
        != PackageManager.READ_EXTERNAL_STORAGE) {

    // Should we show an explanation?
    if (shouldShowRequestPermissionRationale(
            Manifest.permission.READ_EXTERNAL_STORAGE)) {
        // Explain to the user why we need to read the contacts
    }

    requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
            MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);

    // MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
    // app-defined int constant

    return;
}
