    private Button btnOpen;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_reader);

        btnOpen.setOnClickListener(new OnClickListener() {
            public void onClick(View arg0) {

                String filename = null;
                File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +"/"+ filename);
                Intent target = new Intent(Intent.ACTION_VIEW);
                target.setDataAndType(Uri.fromFile(file),"application/pdf");
                target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

                try {
                    startActivity(intent);

filename is null, so the path you are passing to the third-party app does not point to a PDF file.
