Android Hello World应用程序崩溃:来自Surface.lockCanvasNative的Illegal

Question

我正在尝试运行最简单的Hello World示例应用程序，看起来我可以崩溃它，即使它只显示TextView。

复制步骤：在模拟器中启动它（1.5）。打开应用程序-它显示文本视图，然后按"结束通话"按钮锁定手机。按"menu"（菜单）解锁，然后按"back"（返回）。应用程序崩溃，显示"进程android.prrocess.acore已意外停止…"one_answers"强制关闭"按钮。它并不是一直都会发生，但至少在擦除用户数据后，我每次都能复制它。

我想知道默认的Hello World是否缺少一个被认为对于Hello World来说太高级的细节。。。以一个基本的例子来说，这样的问题看起来不太令人鼓舞=）

你知道缺少什么细节以及如何避免这次撞车事故吗？

Answer 1

在我看来更像是模拟器出了问题。为什么不删除你的模拟器，创建一个新的，然后用一个新项目再试一次呢。

希望这对你有帮助。顺便问一下，你为什么在1.5上使用模拟器？？开始构建最低2.1版的应用程序。

祝你好运。
