Android захватывает видео и загружает его на сервер с помощью одной кнопки ⇐ Android

[Anonymous]

Я создаю приложение, в котором мне нужно захватывать видео и загружать его на сервер, например приложение Vine.

Последовательность работы:
Будет использоваться одна кнопка «Загрузить собственное видео».

Когда пользователь нажимает на кнопку, откроется камера и начнется запись видео. когда пользователь прекращает запись, видео сохраняется в папке на SD-карте и автоматически загружается на сервер.

У меня есть два тестовых проекта. Один захватывает видео и сохраняет его. Другие загружают видео или любой файл на сервер.
При загрузке видеопроекта я предварительно назначаю определенный файл.

Мой вопрос заключается в том, как объединить эти два проекта для удовлетворения моих потребностей.

Я публикую исходный код ниже:

Исходный код для загрузки файла:

// messageText.setText("Uploading file path :- '/mnt/sdcard/"+uploadFileName+"'");

messageText.setText("Uploading file path :- '/storage/emulated/0/"+uploadFileName+"'");

/************* Php script path ****************/
upLoadServerUri = "MY_SERVER_LINK";

uploadButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {

dialog = ProgressDialog.show(MainActivity.this, "", "Uploading file...", true);

new Thread(new Runnable() {
public void run() {
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("uploading started.....");
}
});

uploadFile(uploadFilePath + "" + uploadFileName);

}
}).start();
}
});
}

public int uploadFile(String sourceFileUri) {

String fileName = sourceFileUri;

HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);

if (!sourceFile.isFile()) {

dialog.dismiss();

Log.e("uploadFile", "Source File not exist :"
+uploadFilePath + "" + uploadFileName);

runOnUiThread(new Runnable() {
public void run() {
messageText.setText("Source File not exist :"
+uploadFilePath + "" + uploadFileName);

return 0;
