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

我在卸载另一个应用程序正在进行IPC调用的应用程序时得到了这个错误。

一个假设是;由于“服务”应用程序因为卸载而消失,一些传输缓冲区可能已经被填满,导致这个错误,因为没有东西不再从缓冲区中“弹出东西”。

如果这是你的情况,这个问题可能没什么好担心的。

其他回答

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。

如果您需要调查哪个包裹导致了崩溃,您应该考虑尝试TooLargeTool。

(我发现这是@Max Spencer在接受答案下的评论,这对我的情况很有帮助。)

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

确保你没有在Intent对象中放入大容量的数据。在我的情况下,我添加字符串500k大小,然后开始另一个活动。除了这个例外,它总是失败。我通过使用活动的静态变量避免了在活动之间共享数据——你不需要将它们发送到Intent,然后从Intent中提取。

我有的:

String html = new String();//some string of 500K data.
Intent intent = new Intent(MainActivity.this, PageWebView.class);
//this is workaround - I just set static variable and then access it from another    activity.
MainActivity.htmlBody = timelineDb.getHTMLBodyForTweet(tweet);
//This line was present and it actually failed with the same exception you had.
//intent.putExtra("com.gladimdim.offtie.webview", html);

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:-)
