As for the OOM exceptions, using this and this class drastically reduced them for me. For Android Download Image from URL, we need permission to access the internet to download file and read and write internal storage to save image to internal storage. Android allows every app to run in a sandbox. If an app needs to access certain resources or information outside that sandbox, it needs to request permission from user.
From Android 6. For this, we will use the following lines of code to first check if the required permission is already granted by the user, if not then we will request permission for storage read and write permission.
Now that we have requested and been granted the user permission, to start with android download image from url, we will create an AsyncTask, as you are not allowed to run a background process in the main thread.
After downloading the file MediaScannerConnection, is called to read metadata from the file and add the file to the media content provider so the image is available for the user. In the above lines of code, we have also created a method, showToast to show Toast. Read more here.
The OOM exception could be avoided by following the official guide to load large bitmap. Don't run your code on the UI Thread. Use AsyncTask instead and you should be fine.
I'm still learning Android, so I cannot provide a rich context or reason for my suggestion, but this is what I am using to retrive files from both https and local urls. I am using this in my onActivity result for both taking pictures and selecting from gallery , as well in an AsyncTask to retrieve the https urls.
