I had something very similar thing happening with cursor adapters in fragments on orientation change.

Android loader orientation change. Step 1 Create a new project in Android Studio go to File New Project and fill all required details to create a new project. Supports all orientations which on Android 23 Gingerbread and above includes reverse upside-down and sensor-based orientations. Step 2 Add the following code to reslayoutactivity_mainxml.

During orientation change your Activity is destroyed and recreated but the loaders are not. Log the orientation of the device is now event. Or use the onorientationchange event handler property.

Log the orientation of the device is now event. AsyncTask is a great thing to run complex tasks in another thread. Layout Resources Specifying which layout files are inflated for each orientation.

My Activity implements the loader callbacks. Keep in mind that Android deals with configuration changes for you thus a simple change in orientation is enough to trigger a new call to initLoader. Onorientationchange function event console.

As a means of troubleshooting in the Manifest if I set androidconfigChangesorientation onLoadFinished gets called as expected. In the above code we have taken text view to show orientation changes. And as the instance of AsyncTask is connected to that activity it fails and causes a force close message window.

So you can remove your loading condition and call initLoader in every onCreate callback. This includes support for. A simple orientationchange event on the window.

During these changes the windoworientation property may change. Highlighting both icons will allow that particular app to auto-rotate. In this case the method returns the existing instance and your query is not executed again.

While you can force any application into any orientation not all applications will work correctly in all orientations. There are a different options to handle the orientation changes. Override fun onConfigurationChangednewConfig.

Declare a static boolean at. WindowaddEventListenerorientationchange function alert screen. Set Orientation allows you to force your device into a particular screen orientation.

In the source for LoaderManagerinitLoader I see that if the loader already exists the new callback is set to the LoaderInfo inner object class but I dont see where LoaderregisterListener is called again. On the main screen of Rotation Manager select an orientation by tapping on either the vertical or horizontal icons next to a specific app to lock it into either landscape or portrait mode. Drawable Resources Specifying which drawables are loaded for each orientation.

This method is what you would expect from a mobile API. Configuration superonConfigurationChangednewConfig Checks the orientation of the screen if newConfigorientation ConfigurationORIENTATION_LANDSCAPE ToastmakeTextthis landscape ToastLENGTH_SHORTshow else if newConfigorientation ConfigurationORIENTATION_PORTRAIT ToastmakeTextthis portrait ToastLENGTH_SHORTshow. So I am looking for some kind of best-practice to.

It is worth noting that a call to initLoader does not necessarily starts another loader. Step 3 Add the following code to srcMainActivityjava. By including files in folders that follow naming conventions Android automatically loads the appropriate files when the orientation changes.

Initloader was called in onCreateView also tried onStart and onResume but onCreatLoader as well as the other loader callback methods never were called. OnCreate gets called during screen orientation change since the activity gets destroyed and recreated. The initLoader method creates a new Loader only if for this ID none has been created previously.

But when there is an orientation change or another configuration change while the AsyncTask is still running the current Activity is destroyed and restarted. A value of 0 means portrait view -90 means a the device is landscape rotated to.

Unless youre loading a lot of data then it doesnt hurt to do but you can try the following if you want I havent tested it but in theory I think it would work. If the loader adressed by the specific ID exists it is reused by LoaderManager and your callbacks are reattached to it. Prevent Activity to recreated.

You need to define it in the AndroidManifestxml file.
