Android xUtils3.0 数据库操作出错

我在demo中能操作成功成功，但是放到项目中就出错，权限已加，so包也加了。

public class MyApplication extends Application {

    @Override

    public void onCreate() {

        super.onCreate();

        x.Ext.init(this);

        x.Ext.setDebug(BuildConfig.DEBUG); 

        DbManager.DaoConfig daoConfig = new DbManager.DaoConfig()

            .setDbName("logininfo.db")

            .setDbDir(new File("/sdcard")) 

            .setDbVersion(2)

            .setDbOpenListener(new DbManager.DbOpenListener() {

                @Override

                public void onDbOpened(DbManager db) {

                    db.getDatabase().enableWriteAheadLogging();

                }

            })

            .setDbUpgradeListener(new DbManager.DbUpgradeListener() {

                @Override

                public void onUpgrade(DbManager db, int oldVersion, int newVersion) {

                    // TODO: ...

                    // db.addColumn(...);

                    // db.dropTable(...);

                    // ...

                    // or

                    // db.dropDb();

                }

            });

DbManager db = x.getDb(daoConfig);

Member member =new Member();

member.setUsername("名字");

member.setMobile("136");

member.setUserCategory("1");

db = x.getDb(daoConfig);

try {

db.saveBindingId(member);

} catch (DbException e) {

e.printStackTrace();

}

try {

member = db.findFirst(Member.class);

System.out.println("name:" + member.getMobile());

} catch (DbException e) {

e.printStackTrace();

}

    }

}

放在Application中，项目中要存储用户登录信息，就用框架里的，没想到出问题了，两天了都没解决。请大神们帮帮忙。
