即使在手机上也没有显示 Android 地图，只看到白屏

Question

我的项目有一个地图活动，以及使用意图链接的其他活动。然而，所有其他活动都被看到了；地图仅在手机上显示空白屏幕，并在模拟器上显示错误“更新谷歌播放服务”。请帮忙

Answer 1

您的 api 密钥是使用 SHA1 指纹生成的，该指纹不是从您的计算机生成的，即正在发生指纹不匹配。 或者您提供了错误的 api 密钥。

同时在 sdk 中更新您的 Google Play 服务。

Answer 2

你不能在模拟器上模拟谷歌地图你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，只要确保谷歌服务更新你的 api 密钥没有错并去测试您在真实设备上的应用程序，但是这必须知道我搜索并找到了这个Link 去看看他们描述了您如何在模拟器中运行 Google 地图。

我已经更新了我的答案并显示我的代码与你的有点不同，但它可能对你有帮助

    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 {

你的logcat我明白了

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

实际上，问题与Gingerbread 和older phones 相关，如果他们还没有Play Store installed，则使用the wrong URI。这不是一个安全的假设。大多数开箱即用的 Gingerbread 手机都没有附带它，而且 Google 更新也不一定会安装它。 See the discussion

Answer 4

尝试在您的布局中将 fill_parent 替换为 match_parent，在 android 2.2 之后不推荐使用 fill_parent
另外，请尝试重新生成 api 密钥。
你在什么设备上测试？

Answer 5

认为问题出在 SHA1 Key 上，

1.获取 API 密钥并将其更新为您的 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

>Open Android Studio.
>Open Your Project.
>Click on Gradle (From Right Side Panel, you will see Gradle Bar)
>Click on Refresh (Click on Refresh from Gradle Bar , you will see List
 Gradle scripts of your Project)
>Click on Your Project (Your Project Name form List(root))
>Click on Tasks
>Click on android
>Double Click on signingReport (You will get SHA1 and MD5 in Run Bar)
