react-native-system-settings

This module has been prepared by according to Android Configuration class; https://developer.android.com/reference/android/content/res/Configuration.html

Note:

• Getting the user country: country value of localization object may be tricky in Android systems. To find the certain user country you might check simCountry and networkCountry values of localization object.
• The module doesn't include the all configuration values. However some additional setting values exist like UI Mode Type and is24HourFormat.
• The module doesn't handle the changes of the phone states in real-time (for instance orientation changes)
• Contributions are welcomed. A feature that provides setting the system settings would be great. Another feature that provides getting the system settings from iOS would also be great.

installation

With rnpm using;

1. Run the command of npm i --save react-native-system-settings in the console.
2. Link the native module by using the command below:

$ rnpm link react-native-system-settings

3. And finally run the command of react-native run-android

Manually;

1. Run the command of npm i --save react-native-system-settings in the console.

2. In your settings.gradle add the lines below:

   include ':systemsettings'
   project(':systemsettings').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-system-settings/android')

3. In your android/app/build.gradle add the following line:

   dependencies {
       compile fileTree(dir: "libs", include: ["*.jar"])
       compile "com.android.support:appcompat-v7:23.0.1"
       compile "com.facebook.react:react-native:+"
   		compile project(':systemsettings')  // <-- Add this line
   }

4. The package needs to be provided in the getPackages method of the MainActivity.java file. This file exists under the android folder in your react-native application directory. The path to this file is: android/app/src/main/java/com/your-app-name/MainActivity.java.

   import com.systemsettings.SystemSettingsPackage;  // <-- Add this line
   
   protected List<ReactPackage> getPackages() {
       return Arrays.<ReactPackage>asList(
               new MainReactPackage(),
               new SystemSettingsPackage()  // <-- Also add this line
   		);
   }

5. And finally run the command of react-native run-android

usage

Define a new module variable by using ES6 syntax; import SystemSettings from 'react-native-system-settings'; or by using require method; var SystemSettings = require('react-native-system-settings'); then system settings can gotten in somewhere in code:

SystemSettings.get(
	settings => console.log('settings: ', settings)
)

Also promise-then can be used:

SystemSettings.get().then(settings => console.log('settings: ', settings)).done()

Also ES7 async-await method can be used!

class App extends React.Component {
	componentWillMount() {
		this._loadInitialState()
	}
	
	_loadInitialState = async () => {
		try {
			let settings = await SystemSettings.get()
			// Now settings variable would be filled and can be used!
		} catch (error) {}
	};
}
