Question

我有一个正常运行的应用程序。我按下＆＃34;返回＆＃34;按钮并关闭应用程序，然后我打开应用程序并正常工作我按下＆＃34; home＆＃34;然后转到设备的主屏幕，然后打开应用程序并正常工作

问题如下：

我使用＆＃34; Back＆＃34;或＆＃34; Home＆＃34;如果我使用任务杀手并关闭进程，当我再次打开应用程序时会显示＆＃34;强制关闭＆＃34;

我正在使用一些库。

有一些方法，比如＆＃34;内存不足＆＃34;，＆＃34; OnFinish＆＃34;等，以帮助我处理这个错误？

附带错误

Answer 1

我在这里找到了解决方案https://github.com/maurycyw/StaggeredGridView/issues/12。

只需替换此构造函数即可：

private SavedState(Parcel in) {
    super(in);
    firstId = in.readLong();
    position = in.readInt();
    topOffsets = in.createIntArray();
    mapping = new ArrayList<ColMap>();
    in.readTypedList(mapping, ColMap.CREATOR);
}

private ColMap(Parcel in) {
    tempMap = in.createIntArray();
    values = new ArrayList<Integer>();
    for (int index = 0; index < tempMap.length; index++) {
        values.add(tempMap[index]);
    }
}

tsil的回答是根源，但链接并没有准确解释为什么会发生这种情况。或者如何重现。
