Question

希望每个人，我是法国人，因为我的英语很糟糕。对于我的作业，我必须制作一个应用程序，在谷歌地图中显示我的智能手机位置，但是当我在我的connect.xml中添加片段时，应用程序崩溃：“不幸[app]已经停止”

我的Google Play服务效果很好！

com.google.android.gms文字：ConfigApi连接成功

我认为我的AndroidManifest也很好

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

        android:value="AIzaSyDQDHg-zejSDW1UHhPef79kOeAlkkXWwyM" />
</application>

</manifest>

现在是我的connect.xml

@Override

            }
            break;

}

@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    //map.removeView(this.mMapView);
    super.onDestroy();
}

}

我有一个Main.java，它重定向到Connect.java

这是我的日志

感谢您的帮助！：）

Answer 1

那个工作!!这是因为我忘了这个

<permission
    android:name="com.supinfo.tesas.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />
<uses-permission android:name="com.supinfo.tesas.permission.MAPS_RECEIVE" />

谢谢大家！

Answer 2

你在connect.xml中给出了错误的android：name：

而不是：

android:name="com.google.android.gms.maps.MapFragment"

使用：

class="com.google.android.gms.maps.SupportMapFragment"

在java文件中：而不是

GoogleMap googleMap;
googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

使用：

SupportMapFragment supportMapFragment =
        (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
googleMap = supportMapFragment.getMap();

Answer 3

使用FragmentActivity扩展您的活动，如下所示：

public class Connect extends FragmentActivity implements OnClickListener {

Answer 4

只需为您的清单添加ACCESS NETWORK STATE权限。

  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
