Each directory created this way is added to a parent directory that encapsulates all your app's external storage files, which the system deletes when the user uninstalls your app. If none of the pre-defined sub-directory names suit your files, you can instead call getExternalFilesDir and pass null. This returns the root directory for your app's private directory on the external storage.
Remember that getExternalFilesDir creates a directory inside a directory that is deleted when the user uninstalls your app. If the files you're saving should remain available after the user uninstalls your app—such as when your app is a camera and the user will want to keep the photos—you should instead use getExternalStoragePublicDirectory. These directory names ensure that the files are treated properly by the system. If you know ahead of time how much data you're saving, you can find out whether sufficient space is available without causing an IOException by calling getFreeSpace or getTotalSpace.
These methods provide the current available space and the total space in the storage volume, respectively. This information is also useful to avoid filling the storage volume above a certain threshold. However, the system does not guarantee that you can write as many bytes as are indicated by getFreeSpace. Otherwise, you probably shouldn't write to storage. Note: You aren't required to check the amount of available space before you save your file.
You can instead try writing the file right away, then catch an IOException if one occurs. You may need to do this if you don't know exactly how much space you need.
For example, if you change the file's encoding before you save it by converting a PNG image to JPEG, you won't know the file's size beforehand. You should always delete files that you no longer need. The most straightforward way to delete a file is to have the opened file reference call delete on itself. If the file is saved on internal storage, you can also ask the Context to locate and delete a file by calling deleteFile :.
Note: When the user uninstalls your app, the Android system deletes the following:. However, you should manually delete all cached files created with getCacheDir on a regular basis and also regularly delete other files you no longer need. About Android Legal Support.
