Question

我是Android应用程序的初学者刚刚开始建立第一个＆＃34; HelloWorld＆＃34;应用程序。我按照官方教程和设计模拟器。但是，当我运行它时，模拟器说＆＃34;不幸的是，AndroidFirst已停止＆＃34;。我环顾四周，但不同的解决方案并没有帮助。我是Android的初学者，因此无法找到错误或错误的错误。

以下是logCat：

Answer 1

需要Android支持库

看到这张图片：

enter image description here

然后只需将v7紧凑库项目导入您的工作区并将其作为库添加到您的项目中

您可以在目录中存在SDK的sdk\extras\android\support\v7\appcompat中找到它。

导入后，选择项目右键单击 - ＆gt; 属性 - ＆gt; Android - ＆gt; 添加 - ＆gt; 选择 app compact

点击确定。

Answer 2

我下载API-19＆amp;重新创建了AVD。在第一次尝试时，AVD将“Hello World”显示为模拟器上的默认文本。

不幸的是，AndroidFirst已经停止了
