why new FileWriter(...) return /data/data/com.myapp.client/files/myfile.json (No such file or directory)

Why when I do :

FileWriter fw = new FileWriter("/data/data/com.myapp.client/files/myfile.json", true/*append*/);

on some very few device (one most of them it's work well) I receive : /data/data/com.myapp.client/files/myfile.json (No such file or directory). How can I avoid this error ?

Solution

  • Don't hardcode the path, use Context.getFilesDir instead

    File file = new File(context.getFilesDir(), "file.json")

    See this for reference.
