    private static String inp;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         browser=(WebView)findViewById(R.id.w1);


         // browser.loadDataWithBaseURL("x-data://base",inp,"text/html", "UTF-8",null);
         browser.loadData(inp, "text/html", "UTF-8"); 



    }
    public void insertUndergraduate(){
        AndroidOpenDbHelper androidOpenDbHelperObj = new AndroidOpenDbHelper(this);
        SQLiteDatabase sqliteDatabase = androidOpenDbHelperObj.getWritableDatabase();
        ContentValues contentValues = new ContentValues();
        inp = "<html>"+"<body><h1>hai mohan</h1></body>"+"</html>";
