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

此异常通常在应用程序被发送到后台时抛出。

因此,我决定使用数据片段模式来完全绕过onSavedInstanceState生命周期。我的解决方案还处理复杂的实例状态并尽快释放内存。

首先,我创建了一个简单的片段来存储数据:

package info.peakapps.peaksdk.logic;
import android.app.Fragment;
import android.app.FragmentManager;
import android.os.Bundle;

/**
 * A neat trick to avoid TransactionTooLargeException while saving our instance state
 */

public class SavedInstanceFragment extends Fragment {

    private static final String TAG = "SavedInstanceFragment";
    private Bundle mInstanceBundle = null;

    public SavedInstanceFragment() { // This will only be called once be cause of setRetainInstance()
        super();
        setRetainInstance( true );
    }

    public SavedInstanceFragment pushData( Bundle instanceState )
    {
        if ( this.mInstanceBundle == null ) {
            this.mInstanceBundle = instanceState;
        }
        else
        {
            this.mInstanceBundle.putAll( instanceState );
        }
        return this;
    }

    public Bundle popData()
    {
        Bundle out = this.mInstanceBundle;
        this.mInstanceBundle = null;
        return out;
    }

    public static final SavedInstanceFragment getInstance(FragmentManager fragmentManager )
    {
        SavedInstanceFragment out = (SavedInstanceFragment) fragmentManager.findFragmentByTag( TAG );

        if ( out == null )
        {
            out = new SavedInstanceFragment();
            fragmentManager.beginTransaction().add( out, TAG ).commit();
        }
        return out;
    }
}

然后在我的主活动上,我完全绕过了保存的实例周期,并将责任推迟到我的数据片段。不需要对片段本身使用这个,因为它们的状态会自动添加到Activity的状态中):

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);

    SavedInstanceFragment.getInstance( getFragmentManager() ).pushData( (Bundle) outState.clone() );
    outState.clear(); // We don't want a TransactionTooLargeException, so we handle things via the SavedInstanceFragment
}

剩下的就是弹出保存的实例:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(SavedInstanceFragment.getInstance(getFragmentManager()).popData());
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState( SavedInstanceFragment.getInstance( getFragmentManager() ).popData() );
}

其他回答

我也面临着这个问题的位图数据从一个活动传递到另一个,但我通过使我的数据作为静态数据的解决方案,这对我来说是完美的工作

在活动中首先:

public static Bitmap bitmap_image;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_first);
   bitmap_image=mybitmap;
}

在第二个活动中:

 @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);
   Bitmap mybitmap=first.bitmap_image;
}

对我来说,这个错误是在演示程序中出现的。我对onResume做了评论,并在onStart中写了相同的代码,它对我有用。

 @Override
    public void onStart() {
        super.onStart();
        Goal goal = Session.getInstance(getContext()).getGoalForType(mMeasureType);
        if (goal != null && goal.getValue() > 0) {
            mCurrentValue = (int) goal.getValue();
            notifyPropertyChanged(BR.currentValue);
            mIsButtonEnabled.set(true);
        }
    }
   /* @Override
    public void onResume() {
        super.onResume();
        Goal goal = Session.getInstance(getContext()).getGoalForType(mMeasureType);
        if (goal != null && goal.getValue() > 0) {
            mCurrentValue = (int) goal.getValue();
            notifyPropertyChanged(BR.currentValue);
            mIsButtonEnabled.set(true);
        }
    }*/

一个解决方案是应用程序将数组列表(或任何导致问题的对象)写入文件系统,然后通过Intent将该文件的引用(例如,文件名/路径)传递给IntentService,然后让IntentService检索文件内容并将其转换回数组列表。

当IntentService处理完文件后,它应该要么删除它,要么通过Local Broadcast将指令传递回应用程序以删除它创建的文件(传递回提供给它的相同文件引用)。

要了解更多信息,请参阅我对这个相关问题的回答。

对我来说,它也是FragmentStatePagerAdapter,然而覆盖saveState()不起作用。以下是我的解决方法:

当调用FragmentStatePagerAdapter构造函数时,在类中保持一个单独的片段列表,并添加一个方法来删除这些片段:

class PagerAdapter extends FragmentStatePagerAdapter {
    ArrayList<Fragment> items;

    PagerAdapter(ArrayList<Fragment> frags) {
        super(getFragmentManager()); //or getChildFragmentManager() or getSupportFragmentManager()
        this.items = new ArrayList<>();
        this.items.addAll(frags);
    }

    public void removeFragments() {
        Iterator<Fragment> iter = items.iterator();

        while (iter.hasNext()) {
            Fragment item = iter.next();
                getFragmentManager().beginTransaction().remove(item).commit();
                iter.remove();
            }
            notifyDataSetChanged();
        }
    }
    //...getItem() and etc methods...
}

然后在Activity中,保存ViewPager的位置,并在重写的onSaveInstanceState()方法中调用adapter.removeFragments():

private int pagerPosition;

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    //save other view state here
    pagerPosition = mViewPager.getCurrentItem();
    adapter.removeFragments();
}

最后,在重写的onResume()方法中,如果适配器不为空,则重新实例化它。(如果它是空的,那么Activity是第一次被打开或应用程序被Android杀死后,onCreate将做适配器创建。)

@Override
public void onResume() {
    super.onResume();
    if (adapter != null) {
        adapter = new PagerAdapter(frags);
        mViewPager.setAdapter(adapter);
        mViewPager.setCurrentItem(currentTabPosition);
    }
}

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。
