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

有时活动包括一些片段时,活动需要完全重新创建片段内容, 如果sportFragmentManager.fragments没有清晰的历史片段

    val fragments = sportFragmentManager.fragments
    val transaction = sportFragmentManager.beginTransaction()
    for (frag in fragments){
        transaction.remove(frag)
    }
    transaction.commitAllowingStateLoss()

几次重新创建片段活动将发生(调试使用tooLargeTool)

 W/ActivityStopInfo: Bundle stats:
 W/ActivityStopInfo:   android:viewHierarchyState [size=2304]
 W/ActivityStopInfo:     android:views [size=2256]
 W/ActivityStopInfo:   android:support:fragments [size=519072]
 W/ActivityStopInfo: PersistableBundle stats:
 W/ActivityStopInfo:   [null]

其他回答

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

我也在三星S3上得到了这个例外。 我认为有两个根本原因,

如果你有位图,它会占用太多内存,使用缩小 你在drawable-_dpi文件夹中丢失了一些drawables, android在drawable中寻找它们,并调整它们的大小,使你的setContentView突然跳转并使用大量内存。

使用DDMS并在你播放你的应用程序时查看你的堆,这将给你一些关于哪个setcontentview正在创建问题的指示。

我复制了所有文件夹中的所有图纸,以摆脱问题2。

问题解决了。

This was happening in my app because I was passing a list of search results in a fragment's arguments, assigning that list to a property of the fragment - which is actually a reference to the same location in memory pointed to by the fragment's arguments - then adding new items to the list, which also changed the size of the fragment's arguments. When the activity is suspended, the base fragment class tries to save the fragment's arguments in onSaveInstanceState, which crashes if the arguments are larger than 1MB. For example:

private ArrayList<SearchResult> mSearchResults;

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    if (getArguments() != null && getArguments().getSerializable("SearchResults") != null) {
        mSearchResults = (ArrayList) getArguments().getSerializable("SearchResults");
    }
}

private void onSearchResultsObtained(ArrayList<SearchResult> pSearchResults) {

    // Because mSearchResults points to the same location in memory as the fragment's arguments
    // this will also increase the size of the arguments!
    mSearchResults.addAll(pSearchResults);
}

在这种情况下,最简单的解决方案是将列表的副本分配给片段的属性,而不是分配引用:

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    if (getArguments() != null && getArguments().getSerializable("SearchResults") != null) {

        // Copy value of array instead of reference
        mSearchResults = new ArrayList((ArrayList) getArguments().getSerializable("SearchResults"));
    }
}

一个更好的解决方案是不要在参数中传递这么多数据。

如果没有这个答案和TooLargeTool的帮助,我可能永远也不会找到这个。

有这么多地方TransactionTooLargeException可以发生——这里是Android 8的一个新情况——当有人开始输入EditText时,如果内容太大,就会崩溃。

它与AutoFillManager (API 26中新增)和StartSessionLocked()中的以下代码相关:

    mSessionId = mService.startSession(mContext.getActivityToken(),
            mServiceClient.asBinder(), id, bounds, value, mContext.getUserId(),
            mCallback != null, flags, mContext.getOpPackageName());

如果我理解正确的话,这调用了自动填充服务——在绑定器中传递AutofillManagerClient。当EditText有很多内容时,它似乎会引起TTLE。

在EditText的xml布局声明中添加android:importantForAutofill="noExcludeDescendants"。或者在代码中:

EditText et = myView.findViewById(R.id.scriptEditTextView);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    et.setImportantForAutofill(View.IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS);
}

第二种糟糕的解决方法可能是重写performClick()和onWindowFocusChanged()方法来捕获TextEdit子类本身的错误。但我不认为这是明智的……

重要的是要理解,无论设备功能或应用程序,事务缓冲区被限制为1mb。这个缓冲区用于你所做的每个API调用,并在应用程序当前运行的所有事务之间共享。

我相信它还包含一些特定的对象,如包裹和such (package . get()),因此始终将每个get()与recycle()匹配是很重要的。

这个错误很容易发生在返回大量数据的API调用上,即使返回的数据小于1 MB(如果其他事务仍在运行)。

例如,PackageManager.getInstalledApplication()调用返回已安装的所有应用程序的列表。添加特定的标志可以检索大量额外的数据。这样做很可能会失败,所以建议不要检索任何额外的数据,并在每个应用程序的基础上检索这些数据。

然而,调用仍然可能失败,因此重要的是用一个捕获来包围它,并在必要时能够重试。

据我所知,除了重新尝试并确保检索尽可能少的信息之外,没有解决这个问题的方法。
