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

当前回答

另一个可能的原因是:

我有一个活动，开始自己在onResume()!这会导致大量的事务，导致手机(Galaxy S2)完全冻结(没有ANR或任何东西)，然后硬重置，这本身就是一个巨大的错误。

看看在其他手机上用这个代码会发生什么会很有趣:

class MyActivity extends Activity
{
  // ...
  @Override
  void onResume()
  {
     super.onResume()
     startActivity(new Intent(this, MyActivity.class));
  }
}

我不是说你应该使用那个代码。

其他回答

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()
    }

TransactionTooLargeException已经困扰我们大约4个月了，我们终于解决了这个问题!

发生的是我们在ViewPager中使用FragmentStatePagerAdapter。用户将翻页并创建100多个片段(这是一个阅读应用程序)。

虽然我们在destroyItem()中正确地管理片段，但在android中 FragmentStatePagerAdapter的实现有一个bug，它保持了对以下列表的引用:

private ArrayList<Fragment.SavedState> mSavedState = new ArrayList<Fragment.SavedState>();

当Android的FragmentStatePagerAdapter尝试保存状态时，它将调用该函数

@Override
public Parcelable saveState() {
    Bundle state = null;
    if (mSavedState.size() > 0) {
        state = new Bundle();
        Fragment.SavedState[] fss = new Fragment.SavedState[mSavedState.size()];
        mSavedState.toArray(fss);
        state.putParcelableArray("states", fss);
    }
    for (int i=0; i<mFragments.size(); i++) {
        Fragment f = mFragments.get(i);
        if (f != null && f.isAdded()) {
            if (state == null) {
                state = new Bundle();
            }
            String key = "f" + i;
            mFragmentManager.putFragment(state, key, f);
        }
    }
    return state;
}

正如您所看到的，即使您正确地管理FragmentStatePagerAdapter子类中的片段，基类仍然会存储一个片段。SavedState用于创建的每个片段。TransactionTooLargeException会在数组被转储到parcelableArray时发生，而操作系统不希望它有100+项。

因此，我们的解决方案是重写saveState()方法，不为“状态”存储任何东西。

@Override
public Parcelable saveState() {
    Bundle bundle = (Bundle) super.saveState();
    bundle.putParcelableArray("states", null); // Never maintain any states from the base class, just null it out
    return bundle;
}

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。

我遇到过这个问题，我发现当服务和应用程序之间交换大量数据时(这涉及传输大量的缩略图)。实际上数据大小在500kb左右，IPC事务缓冲区大小设置为1024KB。我不确定为什么它超过了事务缓冲区。

当您通过intent extras传递大量数据时，也会发生这种情况

当您在应用程序中遇到此异常时，请分析您的代码。

您是否在服务和应用程序之间交换了大量数据? 使用intent共享海量数据，(例如用户从gallery共享中选择大量文件按share，所选文件的uri将使用intent传输) 从服务接收位图文件 等待android返回大量数据(例如，当用户安装了大量应用程序时，getInstalledApplications()) 使用applyBatch()处理大量未决操作

当你得到这个异常时如何处理

如果可能的话，将大操作拆分为小块，例如，调用applyBatch()时不要使用1000个操作，而是每个操作使用100个。

服务和应用之间不交换大数据(>1MB)

我不知道怎么做，但是，不要查询android，它可以返回巨大的数据:-)

这一行代码在writeToParcel(包裹dest, int标志)方法帮助我摆脱TransactionTooLargeException。

dest=Parcel.obtain();

在这段代码之后，我只写所有的数据到包裹对象，即dest.writeInt()等。
