我在很多地方看到将SharedPreferences文件复制到SD卡是一个问题,因为每个制造商都将它放在其他地方.

无论文件位于何处,我都想在SD卡上备份.有没有办法做到这一点？

我在下一行使用了毕加索:

    ImageView im = (ImageView)findViewById(R.id.picassotest);
    Picasso.with(this).setLoggingEnabled(true);
    Picasso.with(this).load("http://lacuadramagazine.com/wp-content/uploads/sangeh-monkey-forest-101.jpg").into(im);

但是当我运行应用程序时没有任何显示.我已经添加了INTERNET许可,但仍然没有任何反应.我从中获得的唯一日志记录是:

我究竟做错了什么？
