运行Android 4.2的三星设备上的Android appcompat v7库存在问题.在我的开发者控制台中,我不断遇到以下堆栈跟踪崩溃:

java.lang.NoClassDefFoundError: android.support.v7.internal.view.menu.MenuBuilder
    at android.support.v7.widget.PopupMenu.<init>(PopupMenu.java:66)
    at com.[my-package-name].CustomActivity$5.onClick(CustomActivity.java:215)
    at android.view.View.performClick(View.java:4222)
    at android.view.View$PerformClick.run(View.java:17620)
    at android.os.Handler.handleCallback(Handler.java:800)
    at android.os.Handler.dispatchMessage(Handler.java:100)
    at android.os.Looper.loop(Looper.java:194)
    at android.app.ActivityThread.main(ActivityThread.java:5391)
    at java.lang.reflect.Method.invokeNative(Native Method)
    at java.lang.reflect.Method.invoke(Method.java:525)
    at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:833)
    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:600)
    at dalvik.system.NativeStart.main(Native Method)

这是CustomActivity.java的第215行:

PopupMenu popup = new PopupMenu(CustomActivity.this, mImageViewMenu);

崩溃来自一系列设备,但总是三星,而且始终是Android 4.2.

快速的网络搜索让我相信很多人都有同样的问题,我试图解决这个问题的一些步骤是:

• 检查Android项目属性,确保正确添加appcompat库.
• 检查Java Build Path Order和Export项目属性,确保选中Android Dependencies和Android Private Libraries.
• 确认该类包含在库中(android.support.v7.internal.view.menu.MenuBuilder).
• 确认R.java位于android.support.v7.appcompat的gen目录中.
• 确认AppCompat主题包含在Manifest.xml活动中.
• 清理并重建项目.

尽管有这些步骤,尽管它在所有其他设备和Android版本上工作,但崩溃报告仍然存在.

我刚从日食迁移到工作室.我跟着一个博客将项目从eclipse导出到了工作室.该应用程序在棒棒糖中运行良好,并在棒棒糖前设备中抛出以下错误.

仅在工作室中获取此错误.不是在日蚀.
