Save video to Internal Storage

Question

I have a videoView that plays an video from a path that corresponds to a video file within the android gallery

 VideoView videoView1 = (VideoView)promptsView.findViewById(R.id.videoView09);
            String SrcPath = "/storage/emulated/0/DCIM/Camera/20150824_210148.mp4";
            videoView1.setVideoPath(SrcPath);
            videoView1.requestFocus();
            videoView1.start();

Now, i need to somehow store the video from this videoView to the internal storage for my app privately.

I've managed to do this for photos using

public String saveImageToInternalStorage(Bitmap image, String imgRequestedName) {
    ContextWrapper cw = new ContextWrapper(getActivity());
    File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
    File mypath=new File(directory,imgRequestedName+".jpg");
    String loc = mypath.getAbsolutePath();
    FileOutputStream fos = null;
    try {

        fos = new FileOutputStream(mypath);
        image.compress(Bitmap.CompressFormat.JPEG, 70, fos);
        SharedPreferences pref = getActivity().getApplicationContext().getSharedPreferences("MyPref", Context.MODE_PRIVATE);
        final SharedPreferences.Editor editor = pref.edit();
        editor.putInt("totalImageCount",(pref.getInt("totalImageCount",0))+1);
        editor.commit();

        fos.close();
    } catch (Exception e) {
        e.printStackTrace();
    }

    return mypath.getAbsolutePath();
}

How can i do the equivalent for videos?

and how can i read the video from the internal storage?

Answer 1

Here is the codes to save video to internal storage for your app privately. And also code to read the video from the internal storage. Hope this helps.

//For saving Video...

private void saveVideoToInternalStorage (String filePath) {

    File newfile;

    try {

        File currentFile = new File(filePath);
        String fileName = currentFile.getName();

        ContextWrapper cw = new ContextWrapper(getApplicationContext());
        File directory = cw.getDir("videoDir", Context.MODE_PRIVATE);


        newfile = new File(directory, fileName);

        if(currentFile.exists()){

            InputStream in = new FileInputStream(currentFile);
            OutputStream out = new FileOutputStream(newfile);

            // Copy the bits from instream to outstream
            byte[] buf = new byte[1024];
            int len;

            while ((len = in.read(buf)) > 0) {
                out.write(buf, 0, len);
            }

            in.close();
            out.close();

            Log.v("", "Video file saved successfully.");

        }else{
            Log.v("", "Video saving failed. Source file missing.");
        }



    } catch (Exception e) {
        e.printStackTrace();
    }

}

private void loadVideoFromInternalStorage(String filePath){

    Uri uri = Uri.parse(Environment.getExternalStorageDirectory()+filePath);
    myVideoView.setVideoURI(uri);

}

Saving video in internal storage with uuid

private void saveVideoToInternalStorage() {
    UUID uuid = UUID.randomUUID();

    try {

        File currentFile = new File(filePath);
        File loc = Environment.getExternalStorageDirectory();
        File directory = new File(loc.getAbsolutePath()+"/FolderNameWhateverYouWant");
        directory.mkdir();
        String fileName = String.format( uuid+".mp4");
        File newfile = new File(directory, fileName);


        if(currentFile.exists()){

            InputStream inputStream = new FileInputStream(currentFile);
            OutputStream outputStream = new FileOutputStream(newfile);

            byte[] buf = new byte[1024];
            int len;

            while ((len = inputStream.read(buf)) > 0) {
                outputStream.write(buf, 0, len);
            }

            outputStream.flush();
            inputStream.close();
            outputStream.close();

            Toast.makeText(getApplicationContext(),"Video has just saved!!",Toast.LENGTH_LONG).show();

        }else{
            Toast.makeText(getApplicationContext(),"Video has failed for saving!!",Toast.LENGTH_LONG).show();
        }


    } catch (Exception e) {
        e.printStackTrace();
    }

}

Do not forget the request permission

 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Saving a video using it's path to internal storage :

 ContextWrapper cw = new ContextWrapper(getActivity());
 File directory = cw.getDir("vidDir", Context.MODE_PRIVATE);
 File mypath=new File(directory,vidRequestedName+".mp4");

            try {
                FileOutputStream newFile = new FileOutputStream (mypath);
                //path 0 = current path of the video
                FileInputStream oldFile = new FileInputStream (path0);

                // Transfer bytes from in to out
                byte[] buf = new byte[1024];
                int len;
                while ((len = oldFile.read(buf)) > 0) {
                    newFile.write(buf, 0, len);
                }
                newFile.flush();
                newFile.close();
                oldFile.close();

You should use uri. In the example I created a "raw" file in resources but you can modify as you want.

Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.example.mp4);
videoView.setVideoURI(uri);
