我的谷歌地图有问题：没有地图出现，只有这样的白色地图图块：http: //oi47.tinypic.com/2uh0sk0.jpg

我试图生成一个新的 API 密钥，但它仍然不起作用，我不明白为什么......

这里是logcat：

您在 android 清单文件中的包名称有问题：

检查这个：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android"
    android:versionCode="1"
    android:versionName="1.0" >

和

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

将其更正为相同。

您已经添加了不同的权限，MAPS_RECEIVE然后它如何接收地图？将其更改为

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

在 Google API 控制台中，确保您已打开“Google Maps Android API v2”服务，而不仅仅是“Google Maps API v2”服务。

当您生成 API 密钥时，请确保您也在 DEBUG 模式下这样做。
我想，这就是你问题的根本原因。

您将需要两个单独的密钥；一个用于 DEV（在模拟器等中使用的未签名应用程序）
和一个用于 LIVE（在签署您的应用程序时使用）。

  1. :com.kurtis.myapp你在 Manifest 中的包名不应该是com.example.android

  2. 尝试class="com.google.android.gms.maps.MapFragment"在您的布局中使用

  3. 在您的主要活动中使用 Activity 而不是 FragmentActivity 并替换
    mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap(); mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);

    有了这个：

    mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)) .getMap(); mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);

希望这有帮助
