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……

其他回答

这个问题没有一个特定的原因。对我来说,在我的Fragment课上我是这样做的:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    super.onCreateView(inflater, container, savedInstanceState);
    View rootView = inflater.inflate(R.layout.snacks_layout, container); //<-- notice the absence of the false argument
    return rootView;
}

而不是这样:

View rootView = inflater.inflate(R.layout.softs_layout, container, false);

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();

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。)

所以对我们来说,我们试图通过我们的AIDL接口发送一个太大的对象到远程服务。事务大小不能超过1MB。请求被分解为512KB的独立块,并通过接口一次发送一个。我知道这是一个残酷的解决方案,但是,嘿,它是Android:(

我发现了这个问题的根本原因(我们得到了“添加窗口失败”和文件描述符泄漏mvds说)。

Android 4.4的BitmapFactory.decodeFileDescriptor()有一个bug。 只有当BitmapOptions的inPurgeable和inInputShareable设置为true时才会发生。这在与文件交互的许多地方造成了许多问题。

注意,该方法也是从MediaStore.Images.Thumbnails.getThumbnail()调用的。

通用图像加载器受此问题影响。毕加索和格莱德似乎没有受到影响。 https://github.com/nostra13/Android-Universal-Image-Loader/issues/1020
