我正在尝试使用Picasso加载一些我从客户端后端获得的图像但是在android 4.4上它不起作用。来自互联网的所有其他网址我尝试工作正常，除了我从后端获得的那些。
private ImageView imageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView = (ImageView) findViewById(R.id.image);
Picasso.with(this)
.load("https://sdo.gsfc.nasa.gov/assets/img/latest/latest_2048_HMIIC.jpg")
.into(imageView);
}
如果我用网上的任何其他网址替换https://sdo.gsfc.nasa.gov/assets/img/latest/latest_2048_HMIIC.jpg，它将正常工作。
我得到的日志：

我认为后端图像尺寸太大，所以毕加索需要花时间加载到imageview上。所以使用毕加索的占位符和错误方法并等待20秒我认为它会加载。
Picasso.get()
.load(url)
.placeholder(R.drawable.user_placeholder)
.error(R.drawable.user_placeholder_error)
.into(imageView);
