我想提出一个应用程序，我要捕捉视频并上传到像葡萄树的应用服务器。
工作流程：一个键将使用“上传自己的视频”
当用户点击该按钮就会打开相机，并开始录制视频。 当用户停止记录视频将一个文件夹保存在SD卡，并自动上传到服务器。
我有两个测试项目。 一个捕获视频并保存它。 其他上传视频或服务器上的任何文件。 在上传视频的项目，我有预分配一个特定的文件。
我的问题是如何合并这两个项目来完成我的需要。
我下面张贴的源代码：
上传文件的源代码：
// 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 :"
