How to delete internal storage file in android?

Question

I have used the Android internal storage to save a file for my application (using openFileOutput) but I would like to delete that file, is it possible and how?<

Answer 1

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.

myFile.delete();

If the file is saved on internal storage, you can also ask the Context to locate and delete a file by calling deleteFile():

myContext.deleteFile(fileName);

Note: When the user uninstalls your app, the Android system deletes the following: All files you saved on internal storage All files you saved on external storage using getExternalFilesDir(). 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.

Answer 2

 void clearMyFiles() {
    File[] files = context.getFilesDir().listFiles();
    if(files != null)
        for(File file : files) {
           file.delete();
        }
 }
