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

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。

其他回答

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]

对我来说，TransactionTooLargeException发生时，我试图发送大位图图像从一个活动到另一个通过意图。我通过使用应用程序的全局变量解决了这个问题。

例如，如果你想从活动A发送一个大的位图图像到活动B，那么将这个位图图像存储在全局变量中

((Global) this.getApplication()).setBitmap(bitmap);

然后启动活动B并从全局变量中读取

Bitmap bitmap = ((Global) this.getApplication()).getBitmap();

当我试图bulkInsert一个大ContentValues[]时，我在我的syncadapter中得到了这个。我决定修改如下:

try {
    count = provider.bulkInsert(uri, contentValueses);
} catch (TransactionTooLarge e) {
    int half = contentValueses.length/2;
    count += provider.bulkInsert(uri, Arrays.copyOfRange(contentValueses, 0, half));
    count += provider.bulkInsert(uri, Arrays.copyOfRange(contentValueses, half, contentValueses.length));
}

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()
    }

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。
