java - android sqlite delete database in package -

i used following code

string destdir = "/data/data/" + getpackagename() +             "/databases/";     string destpath = destdir + "jobs";     file f = new file(destpath);     if (!f.exists()) {         //---make sure directory exists---         file directory = new file(destdir);         directory.mkdirs();         //---copy db assets folder          // databases folder---         try {             copydb(getbasecontext().getassets().open("jobs"),                     new fileoutputstream(destpath));         } catch (filenotfoundexception e) {                  e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         }     } public void copydb(inputstream inputstream, outputstream outputstream)  throws ioexception {     //---copy 1k bytes @ time---     byte[] buffer = new byte[1024];     int length;     while ((length = inputstream.read(buffer)) > 0) {         outputstream.write(buffer, 0, length);     }     inputstream.close();     outputstream.close(); } 

this copies database assets folder data/data database folder , can use if not there.

i need able delete file in package , copy file assets every time app runs.

i update data in database copying new database assets folder each time , unless un-install app , re install new data not added.

i want load database folder on device user has update replace file , app reads new file that's later.

so... remove line:

 if (!f.exists()) { 

and corresponding closing bracket (})

this copy db always, when run app.
(it implicitly deletes file you, if found)
