Geocoder works in 1.6 but not in 2.2 emulator

问题

getFromLocationName() alsways throws a NullPointerException in the Android 2.2 emulator but it's working fine in the Android 1.6 emulator.

This is my code snippet:

Geocoder geo = new Geocoder(GeocoderAppActivity.this, Locale.getDefault());     

try {       
    List<Address> add = geo.getFromLocationName("Tagore Road,Rajkot", 1);
    while (add.size() == 0) {
        Log.e("Girish", "in while");
        add = geo.getFromLocationName("Tagore Road,Rajkot", 1);
    }
}

What is wrong?

回答1:

In the emulator, are you using the regular Android 2.2, or the Google Apis [Android 2.2] version?

If you use the regular Android 2.2 one, it won't work. As far as I know it does not have the functionality to fulfill your actions. Open your SDK manager and download the Google Apis [Android 2.2] and create an AVD with that. Then try again, it should work.

It's a known bug which they never fixed see service not available I think you will find that it works in the the API level 7 emulator.

Yes this is a Bug but I think it shall run on device.
