Как загрузить большие файлы на сервер PHP в Android

Я пытаюсь загрузить файлы, такие как изображения и песни, на свой PHP-сервер, но когда я пытаюсь загрузить большой файл (размер файла 5 МБ или более), я сталкиваюсь с некоторыми ошибками. Я могу успешно загрузить файлы размером около 500 КБ. Пожалуйста, помогите мне, дайте мне знать, как я могу загрузить файл большого размера ..

Код для java-файла:

public class UploadAudioDemo extends Activity {

    private static final int SELECT_IMAGE = 1, SELECT_AUDIO = 2;
    String selectedPath = "";
    Button ImageBtn, AudioBtn;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ImageBtn = (Button)findViewById(R.id.image_btn);
        AudioBtn = (Button)findViewById(R.id.audio_btn);
        ImageBtn.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent = new Intent();
                intent.setType("image/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);
                startActivityForResult(Intent.createChooser(intent,"Select Image"), SELECT_IMAGE);
            }
        });
        AudioBtn.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {

Я подождал 25-30 минут, но экран остается прежним, и файл не загружается на сервер...

Пожалуйста помоги..
