Question

我的项目有一个地图活动，其中包含使用意图链接的其他活动。然而，所有其他活动都已被看到;地图只显示手机上的空白屏幕，并在模拟器上显示错误“更新Google Play服务”。请帮忙

Answer 1

您无法在模拟器上模拟谷歌地图，您只需要一个真正的设备来处理地图，因为adt模拟器没有安装谷歌播放服务，只需确保谷歌服务更新您的API密钥没有错误并进行测试你的应用程序在真实设备上，但必须知道我搜索并发现这个Link去看看它们描述了你如何在模拟器中运行谷歌地图。

我已经更新了我的答案并显示了我的代码与您的代码略有不同但可能对您有所帮助

enter image description here

public class MainActivity extends FragmentActivity {

private static final int GPS_ERRORDIALOG_REQUEST = 9001;
GoogleMap mMap;
MapView mMapView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (servicesOK()) {
        Toast.makeText(this, "Ready to map!", Toast.LENGTH_SHORT).show();
        setContentView(R.layout.activity_mapview);

        // 1- get reference to MapView
        mMapView = (MapView)findViewById(R.id.map);
        // 2- MapView has the same life cycles as the Activity 
        mMapView.onCreate(savedInstanceState);


    }else {
        setContentView(R.layout.activity_main);
    }

}

@Override
protected void onDestroy() {
    super.onDestroy();
    mMapView.onDestroy();
}

@Override

    super.onPause();
    mMapView.onPause();
}

@Override

    super.onResume();
    mMapView.onResume();
}

@Override

    mMapView.onSaveInstanceState(outState);
}

@Override

    super.onStart();
}

@Override
protected void onStop() {
    super.onStop();
}

@Override
public void onLowMemory() {
    super.onLowMemory();
    mMapView.onLowMemory();
}

@Override

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);

}

Answer 2

您的api密钥是使用SHA1指纹生成的，该指纹尚未从您的计算机生成，即发生指纹不匹配。或者你提供了错误的api密钥。

同时在sdk中更新您的Google Play服务。

Answer 3

来自你的logcat我看到了

02-20 07：35：30.271：E / AndroidRuntime（1811）： android.content.ActivityNotFoundException：找不到要处理的Activity Intent {act = android.intent.action.VIEW dat = market：// details？

实际上，问题与Gingerbread和older phones使用the wrong URI有关，如果他们还没有Play Store installed。这不是一个安全的假设。大多数开箱即用的姜饼手机都没有配备它，谷歌更新不一定安装它。 See the discussion

Answer 4

尝试在布局中用match_parent替换fill_parent，在android 2.2之后不推荐使用fill_parent。另外，尝试重新生成api密钥。
你正在测试什么设备？

Answer 5

认为问题是SHA1密钥，

1.获取API密钥并将其更新为google_maps_api.xml文件。 https://developers.google.com/maps/documentation/android-api/start#step_4_get_a_google_maps_api_key

2.生成Sha1

after 0 {
    chan configure stdin -blocking 0 -buffering none
    fileevent stdin readable {
        exit
    }
    after 20000 exit
    while true {
        puts -nonewline .
        update
    }
}
vwait forever
