在我开发的appwidget中，我有一个问题，当我在Android 2.1和1.5中启动地图活动时会导致崩溃。我只在1.5和2.1中记录过这个，它可能发生在1.6但我还没有测试过。如果我让应用程序运行一段时间，比如在触摸它之前30分钟到一小时，问题就会神奇地消失。
我非常确信这不是我的应用中的错误，而是Android错误。有办法解决它吗？

相关代码，从标签活动中启动地图活动：
intent=new Intent().setClass(this, ExampleMaps.class);
intent.putExtra("t1",t1);
intent.putExtra("t2",t2);
intent.putExtra("m1",m1);
intent.putExtra("details",details);
spec=tabHost.newTabSpec("Examples").setIndicator("", res.getDrawable(R.drawable.example_tab_icons_map)).setContent(intent);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
tabHost.addTab(spec);
(..)
tabHost.setCurrentTab(0);
地图活动：
public class ExampleMaps extends MapActivity
{
private MapController mapController;
private MapView mapView;
private LocationManager locationManager;
@Override
protected boolean isRouteDisplayed()
{
return false;
}
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
double t1=0, t2=0;
String alerttext=ExampleWidgetProvider.NODATA, mag, details=ExampleWidgetProvider.NODATA;
int m1=1;
Drawable drawable;
Bundle extras=getIntent().getExtras();
if(extras !=null)
{
(..)
Afetr检查Android java.lang.VerifyError?和其他一些我尚未找到解决方案的地方。
以下内容已正确设置：
project.properties
target=Google Inc.:Google APIs:3
Manifest，在“应用程序”中：
<application
android:label="@string/app_name"
android:icon="@drawable/scaled48">
<uses-library android:name="com.google.android.maps"/>
(...)
</application>
<uses-sdk android:minSdkVersion="3" />
将这些内容包含在地图活动中：
import com.google.android.maps.Overlay;
import com.google.android.maps.OverlayItem;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
