在TransactionTooLargeException上做什么

我得到了一个TransactionTooLargeException。无法复制的。文件里说

The Binder transaction failed because it was too large. During a remote procedure call, the arguments and the return value of the call are transferred as Parcel objects stored in the Binder transaction buffer. If the arguments or the return value are too large to fit in the transaction buffer, then the call will fail and TransactionTooLargeException will be thrown. ... There are two possible outcomes when a remote procedure call throws TransactionTooLargeException. Either the client was unable to send its request to the service (most likely if the arguments were too large to fit in the transaction buffer), or the service was unable to send its response back to the client (most likely if the return value was too large to fit in the transaction buffer). ...

在某个地方，我传递或接收的参数超出了未知的限制。在哪里?

stacktrace没有显示任何有用的东西:

这似乎和观点有关?这与远程过程调用有什么关系?

可能重要的是:Android版本:4.0.3，设备:HTC One X

如果你使用导航组件的ViewPager2 FragmentStateAdapter:

我在onViewCreated()中创建适配器，但每次导航回来时都会重新创建视图。由于某种原因，旧的适配器没有正确地分离并增加包的大小，直到错误发生。我用TooLargeTool调试它，解决方案是避免在onViewCreated()中重新创建适配器。

在我的片段中，我有适配器变量:

var pagerAdapter:HomePagerAdapter?=null

在onViewCreated方法中，我只创建了一次适配器:

if(pagerAdapter == null){
  pagerAdapter = HomePagerAdapter(childFragmentManager, lifecycle, myContent)
}

为了防止IllegalArgumentException，我手动从onDestroyView中的分页器中分离适配器:

override fun onDestroyView() {
   pager.adapter = null
   super.onDestroyView()
}

如果你将位图转换为Base64项目，并将其保存到可打包对象，你应该调整位图的大小与以下代码，

将PNG替换为jpeg，并将质量100替换为75或60:

bitmap.compress(bitmap.compress格式.JPEG, 75, bytearyoutstream)

这个解决办法对我很管用

我在Android Espresso测试中从Stackoverflow错误中获得了TransactionTooLargeException。当我为我的应用程序删除Logcat过滤器时，我在日志中发现了stackoverflow错误堆栈跟踪。

我猜Espresso在试图处理一个非常大的异常堆栈跟踪时引起了TransactionTooLargeException。

这可能发生，因为活动“A”可能有片段，当你导航到活动“B”时。

则活动“A”的活动生命周期为

OnResume - > OnPause () > OnSavedInsanceState ()

这里的OnSavedInsanceState可能会导致崩溃，因为它不能保存太多数据的状态。因此，尝试通过添加以下代码来清除活动“A”的saveInsatnce。

 @Override
protected void onSaveInstanceState(Bundle oldInstanceState) {
    super.onSaveInstanceState(oldInstanceState);
    if (oldInstanceState != null) {
        oldInstanceState.clear();
    }

}

最近我在使用Android的Contacts Provider时遇到了一个有趣的情况。

我需要从内部联系人数据库中加载联系人的照片，根据系统架构，所有这些数据都通过查询传递给联系人提供者。

由于它作为一个单独的应用程序工作-所有类型的数据传输都是通过使用Binder机制执行的，因此Binder缓冲区在这里发挥作用。

我的主要错误是我没有关闭游标与blob数据从接触提供者，因此分配给提供者的内存增加，这膨胀的Binder缓冲区，直到我得到吨!!绑定器事务失败!!消息在我的LogCat输出。

因此，主要的思想是，当你使用外部内容提供程序并从它们获得游标时，当你完成使用它们时，总是关闭它。

I have also lived TransactionTooLargeException. Firstly I have worked on understand where it occurs. I know the reason why it occurs. Every of us know because of large content. My problem was like that and I solved. Maybe this solution can be useful for anybody. I have an app that get content from api. I am getting result from API in first screen and send it to second screen. I can send this content to second screen in successful. After second screen if I want to go third screen this exception occurs. Each of my screen is created from Fragment. I noticed that when I leave from second screen. It saves its bundle content. if this content is too large this exception happens. My solution is after I got content from bundle I clear it.

class SecondFragment : BaseFragment() {

    lateinit var myContent: MyContent

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        myContent = arguments?.getParcelable("mycontent")
        arguments?.clear()
    }
