我不明白这个错误,虽然我在网上搜索了很多次,但无事可做,错误有时出现。 我做了一个使用VOlley库的应用程序,一切运行良好,95%的请求都有效,但有时我有错误;
11-12 12:18:54.991: I/Error(1870): com.android.volley.NoConnectionError: java.io.EOFException 0
我不知道为什么会出现这个错误。在与应用程序连接的示例中,我发送一些信息,如register_id,用于通知GCM,登录,密码和imei,有时我有此错误,显示为0_0
这是我的登录请求(但我的所有请求中都有此错误):

这是因为同时调用多个请求。我已经设置了优先级,它运行正常。
@Override
public Priority getPriority() {
Request.Priority mPriority = Priority.HIGH;
return mPriority;
}
注意:根据需要设置不同的优先级。

在使StringRequest成为凌空之前对您的URL进行编码。或者仅编码您的请求结束参数。
