Save internal file in my own internal folder in Android

Question

I try to save a txt file in my folder  in internal storage  but I face the same problem every time       Source Not Found    I write my code in different ways expressed here as follows but in all ways I have the same problem   It is worth saying that I even add      lt uses-permission   android name  android permission WRITE EXTERNAL STORAGE   gt    in Manifest xml that is not  necessary for internal storage   It is needless to say that I don t have any problem to save files in  data data package files path  but when I add my folder in the files  root for example  data data package files myforlder myfile txt I face the  Source Not Found  problem    Could you point me in right direction to solve this    The second question is that  for saving a file in an external folder in external storage   for example  sdCard or USB storage  is the scenario different or is it same    First Way   OutputStreamWriter out  try       File path new File getFilesDir    myfolder        File mypath new File path  myfile txt        if   mypath exists              out   new OutputStreamWriter openFileOutput  mypath getAbsolutePath     MODE PRIVATE            out write  test            out close                                         Second way   OutputStreamWriter out  try       ContextWrapper cw   new ContextWrapper this       File path   cw getDir  myfolder   Context MODE PRIVATE       if   path exists              path createNewFile            path mkdir              File mypath new File path  myfile txt        if   mypath exists              out   new OutputStreamWriter openFileOutput  mypath getAbsolutePath     MODE PRIVATE            out write  test            out close              Third way   File path getFilesDir    String mypath path toString       myfolder   OutputStreamWriter out  try       File  f   new File mypath     myfile txt       out   new OutputStreamWriter openFileOutput f getPath    MODE PRIVATE         out write  test         out close                                Fourth Way   File path getFilesDir     OutputStreamWriter out      try       File f   new File path getPath       myfolder myfile txt           out   new OutputStreamWriter openFileOutput f getPath    MODE PRIVATE        out write  test        out close                                Fifth way   File path getFilesDir                    OutputStreamWriter out  try       File f   new File path getCanonicalPath       myfile txt        out   new OutputStreamWriter openFileOutput  f getPath    MODE PRIVATE        out write  test        out close

First Way    You didn t create the directory  Also  you are passing an absolute path to openFileOutput    which is wrong      Second way    You created an empty file with the desired name  which then prevented you from creating the directory  Also  you are passing an absolute path to openFileOutput    which is wrong      Third way    You didn t create the directory  Also  you are passing an absolute path to openFileOutput    which is wrong      Fourth Way    You didn t create the directory  Also  you are passing an absolute path to openFileOutput    which is wrong      Fifth way    You didn t create the directory  Also  you are passing an absolute path to openFileOutput    which is wrong   Correct way    Create a File for your desired directory  e g   File path new File getFilesDir    myfolder     Call mkdirs   on that File to create the directory if it does not exist Create a File for the output file  e g   File mypath new File path  myfile txt     Use standard Java I O to write to that File  e g   using new BufferedWriter new FileWriter mypath
