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

作为意图,内容提供者,信使,所有系统服务,如电话,振动器等都使用Binder提供的IPC基础设施。此外,活动生命周期回调也使用这个基础结构。

1MB是系统在特定时刻执行的所有绑定器事务的总限制。

如果在发送意图时有很多事务发生,即使额外的数据并不大,它也可能会失败。http://codetheory.in/an-overview-of-android-binder-framework/

其他回答

这可能发生,因为活动“A”可能有片段,当你导航到活动“B”时。

则活动“A”的活动生命周期为

OnResume - > OnPause () > OnSavedInsanceState ()

这里的OnSavedInsanceState可能会导致崩溃,因为它不能保存太多数据的状态。因此,尝试通过添加以下代码来清除活动“A”的saveInsatnce。

 @Override
protected void onSaveInstanceState(Bundle oldInstanceState) {
    super.onSaveInstanceState(oldInstanceState);
    if (oldInstanceState != null) {
        oldInstanceState.clear();
    }

}

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();
    }
}
}

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;
}

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
