Embedding Google MapView crashes android app-Collection of common programming errors

model : zt180 firmware : android 2.1-update1-20101030 kernel : 2.6.32.9 usbandroid #1608 build number zt180-eng 2.1-update1 20101030 google maps : 4.5.1

Various crashes occur when embedding the google maps component into an android application. I’m connecting to a router via wi-fi for internet access. The stand-alone google maps app seems to work fine. To re-produce, start the maps app and begin scrolling around.

Will fail within a couple of minutes, occassionally on start-up (in setContentView). Most of the errors are when drawing tiles in google code. Sometimes just an Android SEGV.

NOTE : I’ve tested the same app on the Android developer phone 2 (os 1.6) and it works fine.

My android app is as follows:

import com.google.android.maps.MapActivity;
import android.os.Bundle;

public class Maps extends MapActivity {  
  public void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState);  
    setContentView(R.layout.main);   
  }  
  protected boolean isRouteDisplayed() { return false; }  
 }

Basically, lots of bad things start happening..
