How to Record Android Screen Video programmaticall

I know this question has been asked so many times and there are so many question's, answer's and discussions available. But i don't know what to do and what not to do.

I already referred this below all link to get solution with no luck.

Android KitKat start screenrecord from App
screen recorder with kitkat
Screen Recording kitkat with button

With lot's of search i didn't get any simple example to achieve this task. Since 2 day's i am trying to achieve this but with no success.

So the simple question is whether it is possible to record video of our own screen in android. I just heard that it is possible from android 4.4 Kitkat and i also check some app from market.

I know to do this our device should be rooted and other things which required to do this.

But i am not getting how to develop this programmatically. If any one have any idea then please guide me how to do this. or any example or code will be great help.

I appreciate your any kind of help.

I try to develop with this simple piece of code but not getting anything

public void startRecording(View v) {
        File recordfolder = Environment.getExternalStorageDirectory();
        String record = "su      — bit rate 8000000 --time-limit 30 "
                + recordfolder + "Record.mp4";
        recordfolder.mkdir();
        try {
            Process screenrecording = Runtime.getRuntime().exec(record);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

so basically i don't know what i have to do with this Process screenrecording, i mean how can i start progress.

Good Question But the answer depends on what type of platform you want to use to record the screen in android.

Here are some tricks.....

1) Using this class you can record the screen fort that you required rooted device you can test this in genymotion 4.4 also.

public static class MainFragment extends Fragment {
    private Context mContext;

    private EditText mWidthEditText;
    private EditText mHeightEditText;
    private EditText mBitrateEditText;
    private EditText mTimeEditText;
    private Button mRecordButton;

    public MainFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_main, container,
                false);

        mContext = getActivity();

        mRecordButton = (Button) rootView.findViewById(R.id.btn_record);
        mRecordButton.setOnClickListener(RecordOnClickListener);

        mWidthEditText = (EditText) rootView.findViewById(R.id.et_width);
        mHeightEditText = (EditText) rootView.findViewById(R.id.et_height);
        mBitrateEditText = (EditText) rootView
                .findViewById(R.id.et_bitrate);
        mBitrateEditText.addTextChangedListener(BitrateTextWatcher);
        mTimeEditText = (EditText) rootView.findViewById(R.id.et_time);
        mTimeEditText.addTextChangedListener(TimeTextWatcher);

        return rootView;
    }

    private TextWatcher BitrateTextWatcher = new TextWatcher() {
        @Override

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i2,
                int i3) {
            if (TextUtils.isEmpty(charSequence)) {
                return;
            }

            int value = Integer.valueOf(charSequence.toString());
            if (value > 50 || value == 0) {

2) You can capture the screen shots and make the video from it and it will work for the 3.0+ devices And for converting the images to video you can use FFMPEG or JavaCV.

-For Rooted devices(in that you can capture the keyboard screen also)

if (Environment.MEDIA_MOUNTED.equals(Environment
            .getExternalStorageState())) {

        // we check if external storage is\ available, otherwise
        // display an error message to the user using Toast Message
        File sdCard = Environment.getExternalStorageDirectory();
        File directory = new File(sdCard.getAbsolutePath() + "/ScreenShots");
        directory.mkdirs();

        String filename = "screenshot_jpeg_" + i + ".png";
        File yourFile = new File(directory, filename);



        try {
            Process sh = Runtime.getRuntime().exec("su", null, null);
            OutputStream os = sh.getOutputStream();
            os.write(("/system/bin/screencap -p " + "/sdcard/ScreenShots/" + filename).getBytes("ASCII"));


            os.flush();
            os.close();
            sh.waitFor();
            i++;
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

-For without Rooted devices(in that you can not capture the keyboard screen)

if (Environment.MEDIA_MOUNTED.equals(Environment
            .getExternalStorageState())) {

        // we check if external storage is\ available, otherwise
        // display an error message to the user using Toast Message
        File sdCard = Environment.getExternalStorageDirectory();
        File directory = new File(sdCard.getAbsolutePath() + "/ScreenShots");
        directory.mkdirs();

        String filename = "screenshot_jpeg_" + i + ".png";
        File yourFile = new File(directory, filename);



        try {
            Process sh = Runtime.getRuntime().exec("su", null, null);
            OutputStream os = sh.getOutputStream();
            os.write(("/system/bin/screencap -p " + "/sdcard/ScreenShots/" + filename).getBytes("ASCII"));


            os.flush();
            os.close();
            sh.waitFor();
            i++;
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
