apk安装失败& logcat 显示 NoSuchMethodException

Question

正如标题中提到的，编译时，控制台显示： Failed to install ap.apk

但 logcat 显示：

我注释了所有“retour”方法并删除了所有 android:onClick< /em> 与此方法相关，但它没有帮助...之前一切正常...

有人可以帮忙吗？

先感谢您

Answer 1

IllegalStateException: Could not find a method retour(View)

我认为问题在于您（肯定）在 XML 中的方法 retour 上指定了 onClick 但该方法
Java 代码中不存在。

如果问题仍然存在，请尝试清理项目并关闭您的软件电话。
