Android picasso，报错原因

Question

如何在 picasso 中获取错误描述:

    Picasso.with(context)
        .load(getUrl())
        .placeholder(R.drawable.user_thumbnail_big)
        .error(android.R.drawable.ic_dialog_alert)
        .into(viewModel.userImg);

Callback onError( https://square.github.io/picasso/javadoc/index.html ) 方法也没有提供任何参数，我得到了错误图像，但无法弄清楚为什么，logcat 也是沉默的。添加了互联网权限。

感谢您的帮助。

我遇到了同样的问题，我通过以下方式解决了它:

The global instance listener receives HTTP exceptions for reporting upstream to a crash reporting service or analytics service.

问候:https://github.com/square/picasso/issues/379

public class MyClass implements Picasso.Listener {
    @Override
    public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
    // Display the exception
    }
}
