问我没有在日志中打印'Name‘和'Age’吗？(错误在最后提到。)

public class MainActivity extends AppCompatActivity {

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

        try{
            SQLiteDatabase myDatabase=this.openOrCreateDatabase("User",MODE_PRIVATE,null);
            myDatabase.execSQL("CREATE TABLE IF NOT EXISTS user(name VARCHAR,age INTEGER(2),id INTEGER PRIMARY KEY )");
            myDatabase.execSQL("INSERT INTO user(name,age) VALUES('gaurav',20)");
            myDatabase.execSQL("INSERT INTO user(name,age) VALUES('saurav',16)");

            Cursor c=myDatabase.rawQuery("SELECT * FROM user",null);
            int nameIndex=c.getColumnIndex("name");
            int ageIndex=c.getColumnIndex("age");


            c.moveToFirst();
            while(c!=null){
                Log.i("Name",c.getString(nameIndex));
                Log.i("Age", Integer.toString(c.getInt(ageIndex)));  //tring to get this things in logs but instead it shows an error.
                c.moveToNext();
            }
        } catch (Exception e){
            e.printStackTrace();
        }

    }
}
