How to create folder in internal memory

Question

This is my application memory path /data/data/com.myexample.folder/files and it works fine but when I create a new directory like this /data/data/com.myexample.folder/files/photos, it is not created and I wonder what's wrong? How do I create a new folder inside application.

public void loadFeed();
String file paths="data/data/com.myapplication.myfolder/files";
File outputFiles= new file(filePaths);
File files1=outputFile1.listFiles();

For your own directory in file storage:

FileOutputStream outStream = null;
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File(sdCard.getAbsolutePath() + "/camtest");
dir.mkdirs();
String fileName = String.format("%d.jpg", System.currentTimeMillis());
File outFile = new File(dir, fileName);
outStream = new FileOutputStream(outFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
outStream.flush();
outStream.close();
Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
intent.setData(Uri.fromFile(file));
sendBroadcast(intent);

For saving in sub directory inandroid public folders say DCIM:

use File file = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);

Mainly, make sure that your app has the storage permission enabled:

Go to Device Settings>Device>Applications>Application Manager>"your app">Permissions>Enable Storage permission!

Call openFileOutput() with the name of the file and the operating mode.

    String FILENAME = "hello_file";
    String string = "hello world!";

    FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
    fos.write(string.getBytes());
    fos.close();

just use this way:

public void createFile(Context c) throws IOException{
     String FILENAME = timeStamp();
     String string = "hello world!";

     FileOutputStream fos = c.openFileOutput(FILENAME, Context.MODE_PRIVATE);
    fos.write(string.getBytes());
    fos.close();


}
