the GPS can be toggled by
exploiting a bug in the power manager widget. see this
xda thread for discussion.
here's some example code i use
private void turnGPSOn(){
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(!provider.contains("gps")){ //if gps is disabled
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"));
sendBroadcast(poke);
}
}
private void turnGPSOff(){
String provider = Settings.Secure.getString(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"));
sendBroadcast(poke);
}
}
use the following to test if the existing version of the power control widget is one which will allow you to toggle the gps.
private boolean canToggleGPS() {
PackageManager pacman = getPackageManager();
PackageInfo pacInfo = null;
try {
pacInfo = pacman.getPackageInfo("com.android.settings", PackageManager.GET_RECEIVERS);
} catch (NameNotFoundException e) {
return false; //package not found
}
if(pacInfo != null){
for(ActivityInfo actInfo : pacInfo.receivers){
//test if recevier is exported. if so, we can toggle GPS.
if(actInfo.name.equals("com.android.settings.widget.SettingsAppWidgetProvider") && actInfo.exported){
return true;
}
}
}
return false; //default
}
