即使打开一个简单的地图应用程序（无论是在AVD虚拟设备上还是在真正的Android手机上），我都遇到了麻烦。使用Eclipse / ADT最新安装。
代码或多或少直接来自GoogleMaps v2的书籍章节（Wei-Meng Lee / Wrox撰写的“Android应用程序开发手册”）。几周前，在SSD发生故障之前，我简要地运行了类似的代码。我把书中的代码保持不变 - 下载/导入等。其他简单的helloworld和其他应用程序在AVD等上运行良好。
我有：
似乎没有任何帮助。经过4周的挫折之后，我现在正在寻求帮助（如果这是一个简单的错误，可能会得到宽恕！）

我真的认为我在这里寻求帮助之前已经尝试了一切。 （我曾经在20世纪80年代早期手工编写Z80汇编代码并将其手工转换为Hex - 与此相比简直就是这样........）
非常感谢你们的帮助！

你错过了
<uses-permission
android:name="android.permission.ACCESS_NETWORK_STATE"/>
你有
android:minSdkVersion="19"
您需要更改此
public class MainActivity extends FragmentActivity {
要 公共类MainActivity扩展了Activity {
您需要使用MapFragment
class="com.google.android.gms.maps.MapFragment"
还需要改变
map = ((MapFragment) getFragmentManager()
.findFragmentById(R.id.map)).getMap();
你也不需要
<permission
android:name="net.learn2develop.googlemaps.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="net.learn2develop.googlemaps.permission.MAPS_RECEIVE" />
