我想通过code对GPS进行切换。以下是code我用。

I am trying to switch on GPS by code. The following is the code I've used.

String provider = Settings.Secure.getString(context.getContentResolver(),Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(provider.contains("gps")){ //if gps is enabled
    final Intent poke = new Intent();
    poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
    poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
    poke.setData(Uri.parse("3")); 
    context.sendBroadcast(poke);

在code执行中的onReceive功能。我究竟做错了什么？

The code executing in OnReceive function. What am I doing wrong?

Android的指导方针在4.0以上版本的改变。您不能以编程方式更改GPS关闭在4.0以上的版本。但是，您可以以编程方式更改WiFi关闭

Android Guidelines have changed above version 4.0. You cannot change GPS off on programmatically for versions above 4.0. However, you can change wifi off on programmatically
