Removable volumes, such as an SD card, appear in the file system as part of external storage. Apps themselves are stored within internal storage by default. If your APK size is very large, however, you can indicate a preference within your app's manifest file to install your app on external storage instead:. More recent versions of Android rely more on a file's purpose than its location for determining an app's ability to access, and write to, a given file.
This purpose-based storage model improves user privacy because apps are given access only to the areas of the device's file system that they actually use. To learn more about this permission, and why most apps don't need to declare it to fulfill their use cases, see the guide on how to manage all files on a storage device.
To give users more control over their files and to limit file clutter, apps that target Android 10 API level 29 and higher are given scoped access into external storage, or scoped storage , by default.
Such apps have access only to the app-specific directory on external storage, as well as specific types of media that the app has created. Use scoped storage unless your app needs access to a file that's stored outside of an app-specific directory and outside of a directory that the MediaStore APIs can access.
If you store app-specific files on external storage, you can make it easier to adopt scoped storage by placing these files in an app-specific directory on external storage.
That way, your app maintains access to these files when scoped storage is enabled. To prepare your app for scoped storage, view the storage use cases and best practices guide. If your app has another use case that isn't covered by scoped storage, file a feature request. You can temporarily opt-out of using scoped storage.

Thankfully, apps often contain their own download options internally, letting you save tons of space by moving big audio, video and picture files over to your SD card. But if you want to dig deeper than that, then it makes a strong case for rooting your device taking into consideration all the risks that entails, of course.

Enjoys Android, Windows, and tinkering with retro console emulation to breaking point. I respectfully request my email address be kept incognito. To the comment by Chris C. I respect your opinions on Android and Google, you have a lot of valid reasons to believe what all you are saying about the corporations and the advertising.
I am happy to finally see others speak up to voice their valid opinions, frustrations, and awareness of the problems that exist with the current directions that mobile networks and their technology supplier corporations have done to the mass population.
People are not as stupid as they have been appearing to be for quite awhile now. Brainwashing would not be an exageration in my opinion. As a Communications Media Major, and longtime student of various public service industries; the most horrifying sight is watching all ages of people walking down 20 ft. I am referring to intelligent people. Not the real world in our lives we live in on a daily basis. If you get more to speak up and do something in ways that make a difference, cool.
I use only open source applications on all my computers and phones now, Windows lifer convert. Never been happier now I study programming and coding. I owned the first Droid that came out, several since. I watched having 3g. Now with 4g LTE, limited data, little music is all. Never two apps at the same time without my battery dead by noon, even not using it once in hours. Google claims Android is not Linux, but that it is open source, as they support that; Nothing can be further from the truth.
