"Creating image file to upload" in Android Studio project?

Question

Java

Since Monday I have been trying to implement image loading, which has already petrified the spine (((.

private final static int FILE_CHOOSER_RESULT_CODE = 10000;



private void openImageChooserActivity() {
    Intent i = new Intent(Intent.ACTION_GET_CONTENT);
    i.addCategory(Intent.CATEGORY_OPENABLE);
    i.setType("image/*");
    startActivityForResult(Intent.createChooser(i, "Image Chooser"), FILE_CHOOSER_RESULT_CODE);
  }

  private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(
        Environment.DIRECTORY_PICTURES);
    File imageFile = File.createTempFile(
        imageFileName,  /* prefix */
        ".jpg",         /* suffix */
        storageDir      /* directory */
    );
    return imageFile;
  }

I'm new, I don't know much yet. There is no one to tell ... Maybe someone knows the solution to this problem? Respond!!!
