我使用eclipse作为IDE来编写一个简单的测试程序，将一些TextView和Button放在屏幕上并且工作正常。
然后，我做......
（1）将编译器合规性级别设置为15
（2）将ANDROID_SDK_PLATFORM设置为C：/ ADT / sdk / platforms / android-15
（3）将这些添加为外部JAR
osmdroid-android-4.2.jar
slf4j-android-1.7.7.jar
的AndroidManifest.xml

编译确定，apk安装确定，但应用程序崩溃... （我使用带有android 4.2.2的真实手机作为调试设备。） 这是日志：

我解决了。添加osmdroid-android-4.2.jar，osmdroid-third-party-4.2.jar，slf4j-android-1.7.7.jar和slf4j-api-1.7.7作为外部JAR。并将所有四个文件放入“test”项目的libs目录中。
