我是Android编程的新手，我遇到了问题。当我的代码运行时，我的设备屏幕上显示错误“不幸[app]已停止”。
这是我的活动
package com.android.markermap;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;
public class MainActivity extends Activity {
static final LatLng BANDUNG = new LatLng(-6.904955,107.61034);
static final LatLng BOGOR = new LatLng(-6.589581,106.799755);
private GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
.getMap();
Marker bandung = map.addMarker(new MarkerOptions().position(BANDUNG).title("Berat"));
Marker bogor = map.addMarker(new MarkerOptions().position(BOGOR).title("Ringan").snippet("Kiel is cool"));
// Move the camera instantly to hamburg with a zoom of 15.
map.moveCamera(CameraUpdateFactory.newLatLngZoom(BANDUNG, 12));
// Zoom in, animating the camera.
map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
这是我的布局代码
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"

任何人都有这个问题的想法吗？ 我非常困惑，我希望你能解决这个问题。
答案 0 :(得分：0)
实际上阅读错误有助于你知道很多
The meta-data tag in your app's AndroidManifest.xml does not have the right value. Expected 4030500 but found 0. You must have the following declaration within the <application> element: <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
答案 1 :(得分：0)
您的代码很好但是对于Google Play服务修订版13，您应该在manifest.xml中添加一个元标记。将其插入应用程序标记内。因此，您的应用程序标记中将有两个元标记。如果您仍然需要任何帮助。只需按照link
<meta-data android:name="com.google.android.gms.version" android:value="4030500" />
