我的代码是:

public class EventDataSQLHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "my.db";
}

public class Test extends Activity {
    EventDataSQLHelper eventsData;

    @Override
    protected void onDestroy() {
        System.out.println("onDestroy");

        close();
        if (db!=null){

        db.close();

    }
    super.onDestroy();
}




public void close() {
    eventsData.close();
}

我在这里关闭了数据库..在我的所有活动中除了它的工作(没有显示异常)..这里当我按下此测试活动的后退按钮时,抛出以下异常

02-14 15:59:34.642: ERROR/Database(535): close() was never explicitly called on database '/data/data/com.tesy.connect/databases/test.db'

我们如何在Android中实施密码强度检查器？

如何以Microsoft Office 365 on Android编程方式连接.请提供一些样品展示how to integrate Office 365 in android.

我需要获取设备当前的地理位置.

场景:如果我在US...:

my device location should be US

与案件相同,当我在 UK:

my device location should be UK

我需要示例代码来查找此地理位置.(location determined by Network Location Provider)
