问题
I am making an application where i have to capture video and upload it to server like vine application.
Flow of the work: One button will be used "Upload your own video"
When user clicks on the button it will open camera and will start recording video. when user stops recording the video will save on a folder on sdcard and and automatically upload to server.
I have two test project. One capturing video and saving it. Other uploads video or any file onto server. On upload video project i have pre-assign a particular file.
My question is how to merge these two projects to accomplish my needs.
I am posting source code below:
Source code for file upload:
// 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;
}
else

回答1:
In your code for video capture you have called
startActivityForResult(intent,CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE);
Merging them, add onActivityResult to the same file
@Override
protected void onActivityResult(int requestCode, final int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
dialog =ProgressDialog.show(Activity.this, "", "loading...",false,true);
if (requestCode == CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
new Thread(new Runnable() {
@Override
public void run() {
//call code in upload
runOnUiThread(new Runnable() {
@Override
public void run() {
dialog.dismiss();
}
});
}
}).start();

Just copy the code from 1st project into 2nd project to upload your video or any file on server and pass the uri as of your file to uploading function thats it. Also you can use retrofit 2 or looj to upload your file on server.
