RejectedExecutionException 128 Active Threads AsyncTaskLoader

由 橙三吉。 提交于 2019-12-10 11:14:17
问题 I've searched around for solutions to RejectedExecutionException using AsyncTaskLoader but none have worked. Most of them are for AsyncTask like https://github.com/commonsguy/cwac-task/blob/master/src/com/commonsware/cwac/task/AsyncTaskEx.java but AsyncTaskLoader is kind of different. The first thing I tried was in onCreateLoader() doing this before returning a CursorLoader. if (loaderCount >= 100) { cursorLoader.setUpdateThrottle(1000000000); } All that really does is stop the loaders after

Confused about CursorLoaders and using them with a custom SQLiteOpenHelper

由 你说的曾经没有我的故事 提交于 2019-12-10 04:29:06
问题 I'm writing an app that allows people to set alarms for various tasks that they need to do. My current plan is to store all the relevant data into an SQLite database. To that end, I have created a class that extends SQLiteOpenHelper and filled it with methods to handle all the CRUD that I'd expect to have to take in. Knowing that it's generally a bad idea to do all the processing on one thread, I looked up ways to separate the work between threads and found CursorLoader and LoaderManager,

What is the advantage of loaders over Asynctask in Android?

由 帅比萌擦擦* 提交于 2019-12-09 15:39:33
问题 Are there any advantages of Loaders over Async task? Also, how to make loaders compatible for phones with Android froyo. Edit: The primary problem here is that I'm not using the native DB(SqlLite). Using the DB on development server. Obviously, I can't use CursorLoader any more. AsyncTaskLoader has no examples at all. If any, please do link. Is it a better idea to load the data required onto the local DB and then query it using CursorLoader ? 回答1: Yes, Loaders are more advantageous than

MediaStore.Images.Thumbnails.getThumbnail returns wrong thumbnail instead of NULL

由 拜拜、爱过 提交于 2019-12-09 14:40:54
问题 Consider the scenario as in this picture: Three photos, one of them is a large GIF file (3MP). I'm querying MediaStore in order to retrieve the correspondent thumbnails. If I initialize the Cursor via CursorLoader with this sortOrder: MediaStore.Images.Media.DATE_ADDED + " DESC"" What happens: MediaStore returns the previous successfully retrieved thumbnail: Expected behaviour: when MediaStore cannot retrieve the thumbnail of a given image for some reason it has to return NULL, as per its

show Progress Dialog within a CursorLoader in a fragment android

由 怎甘沉沦 提交于 2019-12-08 20:51:40
问题 Good day, as the title say, anyone know how to implement a progress dialog while loading data from a CursorLoader within a fragment. can't find any example in this regard. Any link or guide on how to do it will be highly appreciated. Thank you 回答1: I think @Michal's solution would be good for showing an indeterminate ProgressDialog via ProgressDialog#setIndeterminate(true) so I've added a +1. I'm not sure adding a Fragment to a Fragment like this (SomeFragment adding DialogFragment..) is

Custom CursorAdapter and CheckBox states

由 那年仲夏 提交于 2019-12-08 14:37:34
I have a problem with trying to use a suggested CursorAdapter implementation together with a CursorLoader. The CursorAdapter works beatifully when I can provide it with a static set of data through a Cursor, but when I try and combine this with a CursorLoader I get a problem with nullpointers. I have pinned it down to the fact that when I feed the adapter a cursor, it is initially empty (set to null as is frequently suggested when dealing with a CursorLoader implementation). The Adapter, on instantiation, loops through the cursor to figure out what state a checkbox is in and then goes through

CursorLoader in a Non Activity

由 末鹿安然 提交于 2019-12-08 12:38:46
问题 I have small project where I read system metrics like Calls Logs, SMS Logs etc from content providers. I have created (Call/SMS)Logger classes to read from content providers and save info in object of (Call/SMS)Metrics clases. The MainActivity uses the info in the objects of (Call/SMS)Metrics classes and saves the data in my own database using a databaseOpenHelper class. Now I intend to use CursorLoader to load datafrom contentproviders. The examples I have seen suggest that MainActivity
