android NotificationManagerCompat.areNotificationsEnabled 不工作 [英] android NotificationManagerCompat.areNotificationsEnabled not working

问题描述

NotificationManagerCompat.areNotificationsEnabled() 如何工作?我尝试执行以下操作 appPushEnabled = String.valueOf(NotificationManagerCompat.areNotificationsEnabled());但是它给了我一个错误?

How does NotificationManagerCompat.areNotificationsEnabled() work? I have tried to do the following appPushEnabled = String.valueOf(NotificationManagerCompat.areNotificationsEnabled()); however it is giving me an error?

还说它只适用于某些设备，我需要尝试一下吗?

Also it says it only works on some devices do I need a try catch on it?

推荐答案

经过几个小时的测试，这是我发现的.

After testing for few hours, here is what I have found.

在 App Gradle 文件中，com.android.support:support 应至少为 24，compileSdkVersion 必须为 24

In App Gradle file, com.android.support:support should be minimum 24 and compileSdkVersion has to be 24

android {    
    compileSdkVersion 24      
}    
dependencies {
     compile 'com.android.support:support-v4:24.0.0'
}

然后@petey 的答案将起作用

And then @petey 's answer will be working

NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(context);
boolean areNotificationsEnabled = notificationManagerCompat.areNotificationsEnabled();
