        @Override
        public void onClick(View view) {

            takePicture();
        }
    });

 

    private void takePicture() {

    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    try {
        Uri mImageCaptureUri = null;
        String state = Environment.getExternalStorageState();
        if (Environment.MEDIA_MOUNTED.equals(state)) {
            mImageCaptureUri = Uri.fromFile(mFileTemp);
        }
        else {
            /*

            mImageCaptureUri = InternalStorageContentProvider.CONTENT_URI;
        }   
        intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
        intent.putExtra("return-data", true);
        startActivityForResult(intent, REQUEST_CODE_TAKE_PICTURE);
    } catch (ActivityNotFoundException e) {

        Log.d(TAG, "cannot take picture", e);
    }
}
