我遇到了相同的问题与ViewPager2和FragmentStateAdapter这里的问题是FragmentStateAdapter标记'saveState()'作为最终和ViewPager2类也是最终的，所以我们不能覆盖的方法，建议在其他答案使现有的答案不适用。

在我的情况下，我能够摆脱事务太大的问题，不保存分页器的状态添加\android:saveEnabled="false" '在XML条目的视图分页器

<androidx.viewpager2.widget.ViewPager2
    android:saveEnabled="false"
    android:id="@+id/viewPager"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

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()
    }

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));
}

问题通过以下方式解决:

 Bundle bundle = new Bundle();
  bundle.putSerializable("data", bigdata);
...
  CacheHelper.saveState(bundle,"DATA");
  Intent intent = new Intent(mActivity, AActivity.class);
  startActivity(intent, bb);// do not put data to intent.

In Activity:
   @Override
   protected void onCreate(Bundle savedInstanceState) {
        Bundle bundle = CacheHelper.getInstance().loadState(Constants.DATA);
        if (bundle != null){
            Intent intent = getIntent();
            intent.putExtras(bundle);
        }
        getIntent().getExtra(..);
        ....
   }
   @Override
    protected void onDestroy() {
        super.onDestroy();
        CacheHelper.clearState("DATA");
    }

public class CacheHelper {

    public static void saveState(Bundle savedInstanceState, String name) {
        Bundle saved = (Bundle) savedInstanceState.clone();
        save(name, saved);
    }
    public Bundle loadState(String name) {

        Object object = load(name);
        if (object != null) {
            Bundle bundle = (Bundle) object;
            return bundle;
        }
        return null;
    }
    private static void save(String fileName, Bundle object) {
        try {
            String path = StorageUtils.getFullPath(fileName);
            File file = new File(path);
            if (file.exists()) {
                file.delete();
            }
            FileOutputStream fos = new FileOutputStream(path, false);

            Parcel p = Parcel.obtain(); //creating empty parcel object
            object.writeToParcel(p, 0); //saving bundle as parcel
            //parcel.writeBundle(bundle);
            fos.write(p.marshall()); //writing parcel to file

            fos.flush();
            fos.close();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    private static Bundle load(String fileName) {
        try {
            String path = StorageUtils.getFullPath(fileName);
            FileInputStream fis = new FileInputStream(path);

            byte[] array = new byte[(int) fis.getChannel().size()];
            fis.read(array, 0, array.length);

            Parcel parcel = Parcel.obtain(); //creating empty parcel object
            parcel.unmarshall(array, 0, array.length);
            parcel.setDataPosition(0);
            Bundle out = parcel.readBundle();
            out.putAll(out);

            fis.close();
            parcel.recycle();
            return out;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
public static void clearState(Activity ac) {
    String name = ac.getClass().getName();
    String path = StorageUtils.getFullPath(name);
    File file = new File(path);
    if (file.exists()) {
        file.delete();
    }
}
}

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……

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);
