android take multiple image with camera

I've already made a code for capturing an image using device built-in camera and archiving it in the database server. For each time I captures an image and views it, it will make another ImageView layout dynamically (ex: the image is ic_launcher).

Whenever the ic_launcher image is clicked, it will go to the MainActivity.java page, with the use of intent, to take another image.

My question is, how can I view all of the captured images / archived images in the uploadActivity.java?

Note: the image is viewed in the uploadactivity.java

mainactivity.java

 private void captureImage() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);

    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);

    // start the image capture Intent
    startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
 @Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);

    // save file url in bundle as it will be null on screen orientation
    // changes
    outState.putParcelable("file_uri", fileUri);
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);

    // get the file url
    fileUri = savedInstanceState.getParcelable("file_uri");
}



/**
 * Receiving activity result method will be called after closing the camera
 * */
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // if the result is capturing Image
    if (requestCode == CAMERA_CAPTURE_IMAGE_REQUEST_CODE) {
        if (resultCode == RESULT_OK) {

            launchUploadActivity(true);


        } else if (resultCode == RESULT_CANCELED) {

            // user cancelled Image capture
            Toast.makeText(getApplicationContext(),
                    "User cancelled image capture", Toast.LENGTH_SHORT)
                    .show();

        } else {
            // failed to capture image
            Toast.makeText(getApplicationContext(),
                    "Sorry! Failed to capture image", Toast.LENGTH_SHORT)
                    .show();
        }

    }
}

private void launchUploadActivity(boolean isImage){
    Intent i = new Intent(MainActivity.this, UploadActivity.class);
    i.putExtra("filePath", fileUri.getPath());
    i.putExtra("isImage", isImage);
    startActivity(i);
}
