Java 应用程序在eclipse的emulator中不工作

我是新手，我看了一些教程，设置了我的模拟器，但当我运行hello world程序时，模拟器说不幸的是，应用程序已经停止了

这就是我的控制台的样子

在此之后，我得到了很多日志文件错误

似乎其他人也有同样的问题。将android:targetSdkVersion更改为

19

，如图所示参见答案

它说

您不能将刷卡和操作栏结合使用

作为一个sdk问题

答案告诉您将目标sdk版本更改为19

它还指出

不要把API级别和平台搞得一团糟，就像Android虚拟设备一样。 当标高19+和平台4.2.2+设置为ADV时，一切都按其运行 应该

问题是你的模拟器使用的是4.4WAPI，它是android Wear。这意味着您不能在该仿真器上使用ActionBar，因为它使用Wear框架。尝试将emulator API级别更改为19或21。然后它应该可以工作。

尝试将

android:targetSdkVersion=“21”

更改为

android:targetSdkVersion=“19”

问题出在您的代码中的某个地方。您可以在堆栈跟踪的第4行中看到这一点。你能发布你的主要活动代码吗？我也发布了我的主要活动代码，说明它有效…..）如果答案对你有帮助，你能把它标为已被接受吗@萨加尔
