Start Video Recording using android.provider.MediaStore.ACTION_VIDEO_CAPTURE

In this exercise, when user click on the "Recording Video using Intent" button, it will start activity with android.provider.MediaStore.ACTION_VIDEO_CAPTURE to ask Android system to start a app helping record video.
When user click on the "Playback" button, the video will be played on the VideoView if exist.

Start Video Recording using ACTION_VIDEO_CAPTURE

To ask video recording using android.provider.MediaStore.ACTION_VIDEO_CAPTURE, simple call startActivityForResult() method with Intent of android.provider.MediaStore.ACTION_VIDEO_CAPTURE.

In onActivityResult() call-back function, check resultCode and requestCode. If both valid and match, the uri of the recorded video file can be retrieved using data.getData().

package com.exercise.AndroidIntentVideoRecording;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import android.widget.VideoView;

public class AndroidIntentVideoRecording extends Activity {

final static int REQUEST_VIDEO_CAPTURED = 1;
Uri uriVideo = null;
VideoView videoviewPlay;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonRecording = (Button)findViewById(R.id.recording);
Button buttonPlayback = (Button)findViewById(R.id.playback);
videoviewPlay = (VideoView)findViewById(R.id.videoview);

buttonRecording.setOnClickListener(new Button.OnClickListener(){

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(android.provider.MediaStore.ACTION_VIDEO_CAPTURE);
startActivityForResult(intent, REQUEST_VIDEO_CAPTURED);
}});

buttonPlayback.setOnClickListener(new Button.OnClickListener(){

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if(uriVideo == null){
Toast.makeText(AndroidIntentVideoRecording.this,
"No Video",
Toast.LENGTH_LONG)
.show();
}else{
Toast.makeText(AndroidIntentVideoRecording.this,
"Playback: " + uriVideo.getPath(),
Toast.LENGTH_LONG)
.show();
videoviewPlay.setVideoURI(uriVideo);
videoviewPlay.start();
}
}});
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
if(resultCode == RESULT_OK){
if(requestCode == REQUEST_VIDEO_CAPTURED){
uriVideo = data.getData();
Toast.makeText(AndroidIntentVideoRecording.this,
uriVideo.getPath(),
Toast.LENGTH_LONG)
.show();
}
}else if(resultCode == RESULT_CANCELED){
uriVideo = null;
Toast.makeText(AndroidIntentVideoRecording.this,
"Cancelled!",
Toast.LENGTH_LONG)
.show();
}
}
}

hello ZeRo-cOoL,

I think you can implement your own activity to capture video. Pls refer A simple exercise of Video Capture using MediaRecorder.

Hi, thanks for the reference. But I managed to worked with the built in camera application to take picture and save them in a custom path with a custom file name. I would like to do the same with the built in video recorder application. Is it possible? I found how to get the real path from the URI but haven't been able to change it, or the file name either. thanks for your quick reply
