我使用Google Maps API实现了地图方法。昨天，它工作正常。从那以后，我对eclipse完全没有任何改变，任何与地图有关的方法（包括视图和MapActivity类）或者清单中相应条目中的任何东西 - 我改变的唯一办法是添加一个启动画面，从而将启动器活动从MyLITactivity更改为SplashActivity。Android Maps API：解析界面失败
我的API密钥在清单中，并且我在manifest中包含了uses-library条目。
当我运行应用程序时，logcat的表明这一点：

MapActivity：

final int RQS_GooglePlayServices = 1;
private GoogleMap myMap;
Location myLocation;
LocationManager locationManager;
String provider;
OnLocationChangedListener myLocationListener = null;

switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
case R.id.menu_legalnotices:

AlertDialog.Builder LicenseDialog = new AlertDialog.Builder(MapActivity.this);
LicenseDialog.setTitle("Legal Notices");
LicenseDialog.setMessage(LicenseInfo);
LicenseDialog.show();
return true;
case R.id.itemid_1:
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("google.navigation:q=Limerick Institute of Technology, Limerick"));
startActivity(i);
return true;
case R.id.itemid_2:
//TODO change to local map of LIT
}
return super.onOptionsItemSelected(item);
}
@Override
protected void onResume() {

super.onResume();
}
public void onLocationChanged(Location location) {
myLocationListener.onLocationChanged(location);

}
@Override

//myMap.animateCamera(CameraUpdateFactory.newLatLng(point));
}
}
如果我注释掉OnMapClickListener和OnMapLongClickListener器械（和他们相应的方法）错误消失。
就跟你一样。 – 2013-08-02 03:42:35
