Questions tagged [asynctaskloader]

AsyncTaskLoader is an Android Loader that uses an AsyncTask to do the loading of data in a background thread.

The AsyncTaskLoader, like other types of Android Loaders, is a class that can be used to avoid having to load data on the main UI thread(loading which may block the UI thread and the app itself). The AsyncTaskLoader was introduced in the Android SDK starting with API level 11(Honeycomb) but is available in older versions through the Android compatibility package. More information about the AsyncTaskLoader along with examples of using one can be found in the documentation for the class.
