Question

            if (!mFolder.exists()) {
                mFolder.mkdir();
            }
             FileOutputStream fos = null;
             try {
                 fos = new FileOutputStream(mFolder);
                 bitmap.compress(Bitmap.CompressFormat.PNG,70, fos);

                 fos.flush();
                 fos.close();
              //   MediaStore.Images.Media.insertImage(getContentResolver(), b, "Screen", "screen");
             }catch (FileNotFoundException e) {

                 e.printStackTrace();
             } catch (Exception e) {

                 e.printStackTrace();
             }

you have to create file, before writing into stream.

File mFolder = new File(getFilesDir() + "/sample");
File imgFile = new File(mFolder.getAbsolutePath() + "/someimage.png");
if (!mFolder.exists()) {
    mFolder.mkdir();
}
if (!imgFile.exists()) {
    imgFile.createNewFile();
}
FileOutputStream fos = null;
try {
    fos = new FileOutputStream(imgFile);
    bitmap.compress(Bitmap.CompressFormat.PNG,70, fos);
    fos.flush();
    fos.close();
} catch (IOException e) {
     e.printStackTrace();
}

Use file.createNewFile() if you want to make a file and not a directory. You may also need to use mkDirs() if the path doesn't exist either.

You are opening the directory itself for writing. This does not work. You need to specify a file within the directory, e.g.:

fos = new FileOutputStream(new File(mFolder, "myfile"));

i added code. it showing NullPointerException this line::bitmap.compress(Bitmap.CompressFormat.PNG,70, fos); – srinu_stack Jul 10 '14 at 12:34
That's an unrelated problem. Maybe `bitmap` is `null`? – Henry Jul 10 '14 at 12:36

File sdcard = Environment.getExternalStorageDirectory();
File dir = new File(sdcard.getAbsolutePath() + "/text/");
dir.mkdir();
File file = new File(dir, "sample.txt");
FileOutputStream os = null;
try {
    os = new FileOutputStream(file);
    os.write(enterText.getText().toString().getBytes());
    os.close();
}
catch (IOException e) {
    e.printStackTrace();
}
