如何修改源代码？

Answer 1

当服务和应用程序之间交换大量数据时会发生这种情况（这涉及传输大量缩略图）。实际上，数据大小约为500kb，而IPC事务缓冲区大小设置为1024KB。我不确定为什么它超出了事务缓冲区。

当您通过意图附加传递大量数据时，也会发生这种情况。因此，最终解决此 TransactionTooLarge 异常的方法是，确定具有下级片段，视图等将数据包添加到数据包中的Activity。然后在“活动”中运行此代码：

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    //Clear the Activity's bundle of the subsidiary fragments' bundles.
    outState.clear();
}

这为我解决了。希望这可以帮助某人！
