java.lang.SecurityException：权限拒绝：启动 Intent {act=android.settings.USAGE_ACCESS_SETTINGS}

Question

当尝试以 final Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS); 意图 startActivityForResult(intent, requestCode); 时，我得到 java.lang.SecurityException。有趣的是，此崩溃仅发生在 Android 5.1 - 5.1.1 的华为上我没有华为设备。你能给我建议一下吗？

Answer 1

出于某种原因，华为为此 activity 保留了 <intent-filter>，但他们将其标记为未导出。您无法启动 activity。您所能做的就是捕获异常并向用户解释您无法导航到那里。

Answer 2

根据 android 开发者文档。

In some cases, a matching Activity may not exist, so ensure you safeguard against this.
