找不到处理意图{ act=android.settings.NOTIFICATION_POLICY_ACCESS_SETTINGS }的活动

Question

我使用下面的简单代码来获得在免打扰期间更改振铃器的权限。应用程序正在Android 6.0上进行测试。但是它崩溃了，日志如下

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.NOTIFICATION_POLICY_ACCESS_SETTINGS }

下面是我的代码：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    if (!notificationManager.isNotificationPolicyAccessGranted()) {
        startActivity(new Intent(ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS));
    }
}

我在按钮点击时调用它。

Answer 1

if (Build.VERSION.SDK_INT > Build.VERSION_CODES.M) {
    if (!notificationManager.isNotificationPolicyAccessGranted()) {
        startActivity(new Intent(ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS));
    }
}

Answer 2

只需使用try n catch就可以了。对我很管用

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
                    && !notificationManager.isNotificationPolicyAccessGranted()) {
    try {
        Intent intent = new Intent(Settings.ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS);
                            startActivity(intent);
                        }catch (Exception et){
                            //tell user something went wrong
                        }
    }

Answer 3

试试这段代码，它对我很管用

是的，别忘了在清单中添加权限...

<uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY"/>
