Define this in your class

private static final int CAMERA_REQUEST = 1888;
private static final int MY_CAMERA_PERMISSION_CODE = 100;
Uri picUri;
File imagefile;

Use the below code for capturing picture. The picture is saved in DCIM folder

takePicture.setOnClickListener(new View.OnClickListener() {
            @TargetApi(Build.VERSION_CODES.M)
            @Override
            public void onClick(View v) {

                if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
                    requestPermissions(new String[]{Manifest.permission.CAMERA}, MY_CAMERA_PERMISSION_CODE);
                } else {
                    File pictureDirectory = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
                    String pictureName = getPictureName();
                    imagefile = new File(pictureDirectory, pictureName);
                    picUri = Uri.fromFile(imagefile);
                    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, picUri);
                    startActivityForResult(cameraIntent, CAMERA_REQUEST);
                }

            }
        });


protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {

        imageView.setImageURI(picUri);
    }
}
private String getPictureName() {
    SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss");
    String timestamp = sdf.format(new Date());
    nameOfFile=timestamp + ".jpg";
    return timestamp + ".jpg";

}

NOTE: This code is working and has no errors as i have used this code in one of my projects. It has been extracted from code of mine.

nameOfFile is string variable? – Shayma Jun 20 '18 at 07:39 — Shayma, Jun 20 '18 at 07:39
