FileNotFoundException: /storage/emulated/0/Android

I try this file writer/reader code segment for test:

File file = new File(Environment.getExternalStorageDirectory(), "LM/lm_lisdat_01.txt");
FileOutputStream outputStream = new FileOutputStream(file);
outputStream.write(("test").getBytes());
outputStream.close();

File file = new File(getExternalFilesDir(null), "LM/lm_lisdat_01.txt");
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(new FileInputStream(file)));

In the 4. row i got this error message below but the "lm_lisdat_01.txt" file was created in LM directory:

java.io.FileNotFoundException: /storage/emulated/0/Android/data/hu.abisoft.lm/files/LM/lm_lisdat_01.txt: open failed: ENOENT (No such file or directory)

Can help anyone for answer this (i think simple) question? I'm newby in Android. Thank you!

Solution

  • You are creating the file in one directory and trying to open it for input in another.

    Environment.getExternalStorageDirectory() is /storage/emulated/0

    getExternalFilesDir(null) is /storage/emulated/0/Android/data/hu.abisoft.lm/files

    Use the same directory for file creation and input.
