Question

在我的Codename One应用程序中涉及（Android）Native接口实现，我不时在设备上收到一个ConcurrentModificationException堆栈跟踪读取：

W/System.err: java.util.ConcurrentModificationException
W/System.err:     at java.util.ArrayList$ArrayListIterator.next(ArrayList.java:573)
W/System.err:     at com.codename1.impl.android.AndroidAsyncView.flushGraphics(AndroidAsyncView.java:380)
W/System.err:     at com.codename1.impl.android.AndroidImplementation.flushGraphics(AndroidImplementation.java:1147)
W/System.err:     at com.codename1.impl.CodenameOneImplementation.paintDirty(CodenameOneImplementation.java:580)
W/System.err:     at com.codename1.ui.Display.edtLoopImpl(Display.java:1075)
W/System.err:     at com.codename1.ui.Display.mainEDTLoop(Display.java:997)
W/System.err:     at com.codename1.ui.RunnableWrapper.run(RunnableWrapper.java:120)
W/System.err:     at com.codename1.impl.CodenameOneThread$1.run(CodenameOneThread.java:60)
W/System.err:     at java.lang.Thread.run(Thread.java:841)

我的代码（Codename One部分或本机接口实现）不使用ArrayList，当弹出“内部错误”时，单击“确定”后应用程序可以继续，但我宁愿避免此错误。

我应该在哪里查看以防止发生此错误？

非常感谢任何帮助，

That means code is triggering a native repaint for some reason on a separate thread. Does your native code that interacts with the peer component do so using the Android native UI thread?

If not that might trigger a race condition.
