Launching mobile network settings screen programmatically

I want to launch mobile network settings screen, so that user can enable/disable 3g or data connection. Can anybody tell me which intent I need to use for starting activity. I used

Intent in = new Intent(android.provider.Settings.ACTION_NETWORK_OPERATOR_SETTIN开发者_如何转开发GS ) 

and

Intent in = new Intent(android.provider.Settings.ACTION_DATA_ROAMING_SETTINGS  ). 

but both of these didn't work.

They won't work because there was a bug that was fixed I think in 2.3.

See https://review.source.android.com/#/c/22229/

You can bypass this using (for NETWORK_OPERATOR_SETTINGS)

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.phone", "com.android.phone.NetworkSetting");
startActivity(intent);

Replace NetworkSetting with Settings for DATA_ROAMING_SETTINGS

there's another similar solution described in Error opening mobile network settings menu

UPDATE

I recently tested this and it seems that this workaround is still necessary up to API level 15. Since API level 16 the intents in the question seem to work correctly.

public class SettingsScreen
{

protected static void _showSettingScreen(String intentStr)
{
    try
    {
        Intent intent = new Intent(intentStr);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        Reference.getAppContext().startActivity(intent);
    }
    catch (Exception e) {Reference.showToast(e.toString(), true);}

I'll try to answer, dispite of the fact this question was asked a few years ago. If what you're trying to do is to launch the "Data usage" screen. Try this snippet of code. It worked for me.

Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.setComponent(new ComponentName("com.android.settings",
                "com.android.settings.Settings$DataUsageSummaryActivity"));
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(intent);

There are two possibilities:

It brings up the overall network settings and from there the user can go to mobile networks

startActivity(new Intent(android.provider.Settings.ACTION_WIRELESS_SETTINGS)); 

As Zharf suggested:

It brings up the Mobile network settings and from there the user can enable network

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.phone","com.android.phone.NetworkSetting");
startActivity(intent);

You can use this for Android API 29, which shows a small UI for toggling Wifi/mobile-data :

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
    startActivity(Intent(android.provider.Settings.Panel.ACTION_INTERNET_CONNECTIVITY))
}

https://developer.android.com/reference/android/provider/Settings.Panel#ACTION_INTERNET_CONNECTIVITY

Focusing on Mobile-data settings:

startActivity(Intent(android.provider.Settings.ACTION_DATA_ROAMING_SETTINGS))

Focusing on Wifi settings:

startActivity( Intent(android.provider.Settings.ACTION_WIFI_SETTINGS))

In my case (android 9) this intent lands directly on mobile data settings:

val intent = Intent(Settings.ACTION_DATA_ROAMING_SETTINGS)
context.startActivity(intent)
