我刚开始android编程
当我运行项目时,地图没有出现,甚至 logcat 也没有发出任何错误信号我使用谷歌 API(谷歌公司)模拟器级别 17 这里是主要活动
public class MainActivity extends MapActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
protected boolean isRouteDisplayed() {
return false;
}
}
