问题 Nova Launcher opens their settings with the cogwheel in the upper right. How is this done? How would I place my app's settings activity there? 回答1: On Android 7.0 and higher, you can use this <intent-filter> on your settings activity: <intent-filter> <action android:name="android.intent.action.APPLICATION_PREFERENCES" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> The Settings app should pick that up and make it available to the user via that gear icon. 来源：

Android: Can I enable the GPS without redirecting the user to the settings screen like in “google maps” app

问题 In GPS based applications, it is important that the user enable his GPS. If not then usually we would show a dialog stating that the user " should enable his GPS from the settings to be able to use this functionality ". When the user press OK he will be redirected to the Settings page, I don't like this solution since it takes the user out of the application context in to the settings. I have noticed that "google maps" application has a better solution, which is to show a neat dialog when a

问题 I want to open the Settings-> Sound & Display-> Phone Ringtones screen from my application. How can I do that? 回答1: Depending on your needs, there are a couple of alternatives to bring up the 'Ringtones' settings screen from your application.

Why i ask this: (also the reason for trying it in an app) It happens when we use Google Maps in Lollipop . Even if the Location is disabled, it is turned on, in high accuracy mode after user's input from the Maps app, without having to visit Settings. A similar functionality can be achieved for enabling Bluetooth, where the action is initiated in my app; user needs to make a choice but user is not redirected to Settings, using: startActivity(new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE)); which could be found on BluetoothAdapter , now we know there is no LocationAdapter, so i looked
