Exception when starting activity android.os.TransactionTooLargeException: data parcel size

问题

Creating intent with a large amount of data in extras

   public static Intent createIntent(Context context, List<PhotoItem> gallery, int indexOf) {
       Intent intent = new Intent(context, GalleryViewActivity.class);
       intent.putExtra(EXTRA_PHOTO_INDEX, indexOf);
       intent.putExtra(EXTRA_PHOTO_OBJECT, new Gson().toJson(gallery));
       return intent;
   }

Then running the activity: startActivity(createIntent(...

crashes application with error:

Exception when starting activity android.os.TransactionTooLargeException: data parcel size...

How to avoid such errors when data is too large in the list?

回答1:

You are passing whole List<PhotoItem> to your GalleryViewActivity with Intent. So it might possible that your list of List<PhotoItem> can have many data. So sometime system can not handle much data to transfer at a time.

Please avoid to pass large amount of data with Intent.

You can use SharedPreferences to store your array list and retrieve the same on other activity.

Initialize your SharedPreferences using:

SharedPreferences prefrence =  PreferenceManager.getDefaultSharedPreferences(context);
Editor editor = prefrence.edit();

You can use this way to store list in Preference variable

public static Intent createIntent(Context context, List<PhotoItem> gallery, int indexOf) {
    Intent intent = new Intent(context, GalleryViewActivity.class);
    intent.putExtra(EXTRA_PHOTO_INDEX, indexOf);

    editor.putString("GallaryData", new Gson().toJson(gallery));
    editor.commit();

    return intent;
}

Now in your GalleryViewActivity.java file

SharedPreferences prefrence =  PreferenceManager.getDefaultSharedPreferences(context);
Editor editor = prefrence.edit();

String galleryData = prefrence.getString("GallaryData", "");
List<PhotoItem> listGallery = new Gson().fromJson(galleryData, new TypeToken<List<PhotoItem>>() {}.getType());

You will have your list in listGallery variable. You can retrieve your index as the same way you are using right now.
