Android MapActivity : Couldn't get connection factory client

Solution 1:

i had exactly the same initial situation as you described.

when you see the map tiles there are obviously some missing to see a position on the map:

1. you need a location. i recognized that setting only a geo position via DDMS view to the emulator is not enough. you have to explicitly press every time the "Send" button in DDMS to trigger a location update on your emulator. (just to mention: on a real the device you have sometimes to walk a bit to make your device get a location update ;), i was so pissed off until i walked around thinking of what to do now ^^)

2. you need a correct implementation of ItemizedOverlay with an correct OverlayItem. i wrote my own overlay which got bit "complicated". if you're not sure if your implementation is correct, use this guide to create an implementation with minimal changes Map view tutorial android developers

or use this:

private class MyItemizedOverlay extends ItemizedOverlay {
    private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();

    public MyItemizedOverlay(Drawable defaultMarker) {
          super(boundCenterBottom(defaultMarker));
    }

    public void addOverlay(OverlayItem overlay) {
        mOverlays.add(overlay);
        populate();
    }

    @Override
    protected OverlayItem createItem(int i) {
      return mOverlays.get(i);
    }

    @Override
    public int size() {
      return mOverlays.size();
    }
}

private void updateLocationOverlay() {
    if (location == null) { return };
    List<Overlay> mapOverlays = mapView.getOverlays();
    Drawable drawable = this.getResources().getDrawable(R.drawable.XXXX);
    MyItemizedOverlay myItemizedOverlay = new MyItemizedOverlay(drawable);
    GeoPoint point = new GeoPoint((int)(location.getLatitude() * 1E6), (int)(location.getLongitude() * 1E6));

    OverlayItem overlayitem = new OverlayItem(point, "Hola, Mundo!", "I'm in Mexico City!");
    myItemizedOverlay.addOverlay(overlayitem);
    mapOverlays.add(myItemizedOverlay);
}

i want specially point out that you must call boundCenter or boundCenterBottom on the drawable. else it will not be drawn. be also careful if you use different markers in the same overlay with overlayItem.setMarker, that u call it there too.

3. you have to move the view on the map to your point. you can achieve this like this:

MapController mapController = mapView.getController();
mapController.setCenter(point)

i recognized that the function mapController.zoomToSpan does not work. (at least for me, i am still developing on this app). maybe its the same with animateTo. i did not try. set center works. (and setZoom level also).

Maybe there is something in the points i mentioned which could lead to, that your map does not work like you want.

Good luck!

edit: i forgot to mention that i am still getting that factory client error even it works to get a valid location, real on device and fake on emulator via ddms send). i just ignore for now.

Solution 2:

Please make sure that you use permissions in your application AndroidManifest.xml.

add these 3 lines in AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>

And also make sure keystore is pointing to the keystore you created.

In eclipse Check Window -> Preferences ->Android ->Build : Default Debug keystore, is pointing to the key you created using keytool, else use Browse button and point to the actual key.

Hello fellow developers,

I too experienced this issue and spent nearly half a day trying to figure out what was going on. Initially the map activity would not display at all and I was receiving an error stating, "Couldn't get connection factory client" which in turn created another error, "java.io.IOException: Server returned 3".

The cause of this is that Google have failed to communicate effectively to their development base that whilst in development, i.e. prior to signing and releasing your application, you must sign your application with a debug key which is used whilst testing. To do so, follow the method below replacing the [password] and [key password] with your own passwords.

From your .android directory, issue the following command:

keytool -list -alias androiddebugkey -keystore debug.keystore storepass [password] -keypass [key password]

Upon doing the above you will be pleased to receive your MD5 Certificate fingerprint which you can use to sign up for your Google maps API key. Replace your Google Maps API key in your project, do a Project Clean and re-run your applicat6ion. You should now be able to view your Google Map and be rid of your annoying errors.

I had the same problem with "MapActivity Couldn't get connection factory client" The way I fixed the problem was very simple! I just uninstalled entire application and reinstalled it. It worked!!!
