How to open Android Settings programmatically with Java

In case your app needs that your user make some changes in the Settings menu i.e to set a default app to open a specific type of files etc, you may like to make this task easier for your user by starting the Settings menu of Android dinamically from your app.

Show system settings

To display the Settings page programmatically, you can use the startActivityForResult method with an Intent object and a constant of the Settings, the following example should open the general settings menu of Android:

startActivityForResult(new Intent(android.provider.Settings.ACTION_SETTINGS), 0);

The usage of the ACTION_SETTINGS constant with startActivityForResult will show system settings. The Settings provider contains global system-level device preferences.

Access specific settings areas

The following list contains all the constants that provide access to different areas of the settings menu:

Note: not all the constants are available on every Android version. In case you need more information visit the official documentation here.

startActivityForResult(new Intent(android.provider.Settings.ACTION_LOCALE_SETTINGS), 0);

With the introduction of new Android APIs, there will be more settings available areas with different constants, read the official documentation of android provider settings here.

Add the permissions if required

For some special areas of the Android Settings, you will need permissions. For example, to open the bluetooth settings you’ll need to add the following bluetooth permissions in your app manifest:

And then you’ll be able to open the bluetooth settings:

startActivityForResult(new Intent(android.provider.Settings.ACTION_BLUETOOTH_SETTINGS), 0);

Otherwise you’ll get the following exception:

java.lang.SecurityException: Permission Denial: starting Intent <> requires android.permission.BLUETOOTH_ADMIN

Android open Settings Panel programmatically

In this article, we will learn to open the settings panel programmatically in Android. The Settings.Panel is introduced in Android Q (API 29).

2. Open Settings panel programmatically in Android

Consider we have an app that won’t work without Internet connectivity. So whenever the user opens the application without an internet connection, we will redirect them to the device settings app to turn ON Mobile Data or WiFi. However, the user has to leave our app to navigate to the settings app.

To address the above problem of users needing to leave the current app and open settings application, therefore Android introduces the Settings panel, a floating UI with a fixed subset of settings.

Right now, the Settings panel supports the following settings options:

Let’s learn to show each of these options from your app.

2.1. Internet connectivity Settings panel

You can use the action ACTION_INTERNET_CONNECTIVITY to show the internet connectivity settings panel for users.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q)

2.2. Android NFC Settings panel

To launch the NFC settings panel, use the action ACTION_NFC:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q)

2.3. Android WiFi settings panel

You can use the WiFi settings panel to change the Wifi or toggle. To show the dialog, invoke intent with the action ACTION_WIFI.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q)

2.4. Android Volume Settings panel

To show the Volume settings panel to adjust the volume, use the action ACTION_VOLUME.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q)

2.5. Receive callback using ActivityResultLauncher

Since startActivityForResult is deprecated, we are using the ActivityResultLauncher.launch to launch the intent. The registerForActivityResult reduces complexity such as managing request codes with the startActivityForResult .

First, we had to invoke the new method registerForActivityResult to create the ActivityResultLauncher . Once the instance ActivityResultLauncher is ready, we can then use it to launch the Intents.

For example, the following registerForActivityResult method handles callback from the Settings panel.

var resultLauncher = registerForActivityResult( ActivityResultContracts.StartActivityForResult()) < result ->if (result.resultCode == Activity.RESULT_OK) < >>

If the user presses the “DONE” button in the settings panel dialog or device back button, then the RESULT_CANCELLED result code is returned back to the Activity or Fragment’s ActivityResultLauncher callback method. Inside your callback method, you can write code to check the Wi-Fi \ NFC \ internet connectivity.

3. Conclusion

To sum up, the Settings panel ease things for users and enhance user experience. To learn more about Android, refer to our articles.
