Settings.Secure WIFI_ON Android Application crash

Question

I'm trying to write a simple app, that will change Android(my ver is 2.3.3) settings, but I have some problems. My API level is 10, so I use System.Secure, because Settings.System are deprecated and Settings.Global are in newer APIs.

When I use this code, app crashes :( :

public class OnOff extends Activity {
TextView msg;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//buttonLED = (ToggleButton) findViewById(R.id.toggleButton);
ToggleButton toggle = (ToggleButton) findViewById(R.id.toggleButton);
toggle.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if (isChecked) {
            // The toggle is enabled
            Settings.Secure.putInt(getContentResolver(), Settings.Secure.WIFI_ON, 1);
        } else {
            // The toggle is disabled
            Settings.Secure.putInt(getContentResolver(), Settings.Secure.WIFI_ON, 0);
        }
    }
});
}
}

Of course I use permissions in manifest

<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />

I also tried this code with android:onClick="toggle" but it doesn't work too :/

public class OnOff extends Activity {
TextView msg;
private ToggleButton buttonLED;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}

public void toggle(View v){
if(buttonLED.isChecked()){
    Toast.makeText(OnOff.this, "Setting ON", Toast.LENGTH_SHORT).show();
    Settings.Secure.putInt(getContentResolver(), Settings.Secure.WIFI_ON, 1);
}
else{
    Toast.makeText(OnOff.this, "Setting OFF", Toast.LENGTH_SHORT).show();
    Settings.Secure.putInt(getContentResolver(), Settings.Secure.WIFI_ON, 0);

}
}
}

Does anyone has an idea how to make it work?

You can not change the values of secure table, unless your app is bundled with the system (RTM):

Secure system settings, containing system preferences that applications can read but are not allowed to write. These are for preferences that the user must explicitly modify through the system UI or specialized APIs for those values, not modified directly by applications.
