HostConnection :: get（）新しいホスト接続が確立されました0xafecbf90

Question

このメッセージが表示されたら、New Host Connection establishedは接続OKですか、そうではありませんか？

私はAndroidの

私のアプリケーション上のローカルデータベースに接続しようとしています

try { 
    Class.forName("com.mysql.jdbc.Driver"); 
    Connection con = DriverManager.getConnection(url, user, pass); 
    /* System.out.println("Databaseection success"); */ 

    Log.i("MYLOG", "Message was not handled.1"); 
    String result = "Database connection success\n"; 
    Statement st = con.createStatement(); 
    ResultSet rs = st.executeQuery("select * from depo"); 
    ResultSetMetaData rsmd = rs.getMetaData(); 
    Log.i("MYLOG", "Message was not handled.2"); 
    while (rs.next()) { 
     result += rsmd.getColumnName(1) + ": " + rs.getInt(1) + "\n"; 
     result += rsmd.getColumnName(2) + ": " + rs.getString(2) + "\n"; 
     result += rsmd.getColumnName(3) + ": " + rs.getString(3) + "\n"; 
     Log.i("MYLOG", "Message was not handled.3"); 
    } 

    tv.setText(result); 
} catch (Exception e) { 
    e.printStackTrace(); 
    tv.setText(e.toString()); 
}

私は16の代わりに、15にminSdkVersionを変更し、それが動作します。
