Displaying data in database without using json - mysql

Question

Somehow I got arround with Class.forName("com.mysql.jdbc.Driver");
having class not found exception error but I dont know if it works. I
just added permissions, but now every time i run this app on my
emulator it keeps on catching to SQLException which I set to display
error2.
Why is it not showing my data from my database,,is there something wrong with my code?
public void connDB() {
TextView myTextView = (TextView) findViewById(R.id.text);
try {
StrictMode.ThreadPolicy policy =
new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection(url, user, pass);
String result = "Database connection success";
Statement st = con.createStatement();
ResultSet rs = st.executeQuery("SELECT * FROM Scraped");
ResultSetMetaData rsmd = rs.getMetaData();
while (rs.next()) {
result += rsmd.getColumnName(1) + ":" + rs.getString(1) + "\n";
result += rsmd.getColumnName(2) + ":" + rs.getString(2) + "\n";
result += rsmd.getColumnName(3) + ":" + rs.getString(3) + "\n";
result += rsmd.getColumnName(4) + ":" + rs.getString(4) + "\n";
result += rsmd.getColumnName(5) + ":" + rs.getString(5) + "\n";
}
myTextView.setText(result);
} catch (ClassNotFoundException e) {
myTextView.setText("error1");
} catch (SQLException e) {
myTextView.setText("error2");
}
}
EDIT
This is what i found in logcat,,dang,haha so many i did not include the others but what i can understand is it didnt connect to the server or database.

Answer 1

Never mind,, i solved it my self tuns out i just need to set my host address to 10.0.2.2 so my url look like this.
private static final String url ="jdbc:mysql://10.0.2.2:3306/db";
As described here
