You can also use  file getCanonicalFile   delete

String dir   getFilesDir   getAbsolutePath    File f0   new File dir   myFile    boolean d0   f0 delete     Log w  Delete Check    File deleted      dir     myFile     d0     The code File dir   getFilesDir    doesn t work because this is a request for a File object  You re trying to retrieve the String that declares the path to your directory  so you need to declare  dir  as a String  and then request that the directory s absolute path in String form be returned by the constructor that has access to that information

Have you tried Context deleteFile

User · Answer

The getFilesDir   somehow didn t work  Using a method  which returns the entire path and filename gave the desired result  Here is the code   File file   new File inputHandle getImgPath id    boolean deleted   file delete

Have you tried getFilesDir   getAbsolutePath       Seems you fixed your problem by initializing the File object with a full path   I believe this would also do the trick

File file   new File getFilePath imageUri getValue       boolean b   file delete      is not working in my case   boolean b   file delete                       returns false boolean b   file getAbsolutePath delete       returns false    always returns false   The issue has been resolved by using the code below   ContentResolver contentResolver   getContentResolver    contentResolver delete uriDelete  null  null
