我试图在应用程序中显示地图，但我没有这样做。
我的模拟器运行Google API 19，我将google play服务检查为引用库。
在API控制台上，我启用了Google地图API，但它仍无效。任何帮助表示赞赏！
MainActivity.java：
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

答案 0 :(得分：6)
您的元数据清单标记必须如下：
<!-- Google Maps API Key -->
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyCIafD5------------" />
<meta-data
不像名称和值那样是APIKEY值。
答案 1 :(得分：0)
在您的主要活动中尝试在onResume（）
中检查Google Play服务@Override
public void onResume() {
super.onResume();
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
Log.e("playServicesCheck", "status:" + status);
try {
if (status != ConnectionResult.SUCCESS) {
GooglePlayServicesUtil.getErrorDialog(status, this, 1).show();
}
} catch (Exception e) {
Log.e("PLAY SERVE", "error:" + e);
}
}
答案 2 :(得分：0)
看起来您的问题已经解决，但我发现您的清单也遗漏了这个：
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
我遇到了一个类似的问题，通过添加它来修复。
我正在用这个撕掉我的头发，我正在处理一个正好访问地图的应用程序，然后突然停止了。我无法看到任何指向失踪许可的东西;当我将清单与另一个使用map api v2的应用程序进行比较时，我才接受它。
我的日志中有一些红色鲱鱼（指示我在这里），我在下面分享它们以防有同样问题的人偶然发现：
找不到类＆＃39; gpr＆＃39;，从方法gps.a
引用类Lcom / google / android / gms / location / internal / ParcelableGeofence的链接;＆＃39;失败
我仍然感到困惑的是，为什么它之前没有它（谷歌说你需要地图的工作许可）。也许我曾经把它放在那里并且意外地删除了这条线，但无论哪种方式都把它固定下去了。
