Android应用程序总是崩溃

Question

我是android编程新手，所以我开始关注互联网上的教程，非常简单的东西，但是当我编译它以便在模拟器上运行时，它总是在我的设备模拟器上说:“不幸的是你的程序已经停止” (nexus 4)所以我认为我的java代码有错误。

所以我创建了一个全新的项目，没有使用通常的“hello world”进行修改，所以它应该可以工作，但是当我要运行它时，它看起来是一样的。 “不幸的是，您的程序已停止”。
这是我的控制台上显示的内容。

也许它与我正在使用的 API 版本有关？

Answer 1

使用 targetSdkVersion 作为 19。

<uses-sdk
    android:minSdkVersion="15"
    android:targetSdkVersion="19" />

There is a problem with API 20
