I am using following code in android to create a file :

File path = new File(this.context.getFilesDir() + File.separator + "A");
        File file = null;

        if (!path.exists()){
            //print log 1
            if (! path.mkdirs()){
                //print log 2
            } else {
                //print log 3
                file = new File(path.getAbsolutePath(),"A.json");
            }
        } else {
            //print log 4
            file = new File(path.getAbsolutePath(),"A.json");
            if (file.exists())
            {
                //print log 5
            } else {
                //print log 6
            }
        }
InputStream is = new FileInputStream(file);

Problem:- When i install the APK , first time the above code works . I get the logs : //print log 1, print log 3 . Then i am able to get the input stream.

But next time when this code executes , it goes to print log 4 , print log 5. But when i try to get the input stream it gives me error : java.io.FileNotFoundException: /data/data/com.abc.android.abc/files/A/A.json: open failed: ENOENT (No such file or directory)

Then i am able to get the input stream.. Impossible. You just created directory 'A' and then there would already be a file 'A.json' in it? Impossible. – greenapps
Your code is terrible in many ways. For instance if mkdirs() fails you even try to open the input stream. You should return then. No further execution. – greenapps
I am using following code in android to create a file :. There is nothing in your code that creates a file. – greenapps
@greenapps thanks for comments. I am aware about how to handle if mkdirs fails . But thats not the point i am asking . – Pardeep Kr

whereever you are defining f. You are defining File path and file and try to get an inputstream from f
