Appending to file internal storage android -

-

if have existing file in internal storage in android app, how append string file? have tried using fileoutputstream.write() seems overwrite whole file , causes previous data lost.

as suggested squonk, can manually create fileoutputstream in append mode with:

fileoutputstream(file file, boolean append) fileoutputstream(string path, boolean append)

or alternatively , arguably preferably, using native android method:

openfileoutput(filename, context.mode_append);

which opens file named 'filename' located in default storage location app. best let os decide store files. details on storage options here. describes how access each of standard storage locations , methods. 1 choose depends on trying store.
