当我尝试运行下面给出的RoboSpice-Retrofit示例时
https://github.com/octo-online/RoboSpice-samples/tree/release/robospice-sample-retrofit
我收到错误retrofit.RetrofitError请求网络执行期间发生异常:null
我经历了这个问题
Uploading an image to Google appengine using Robospice with Retrofit
但这并不能解决我的问题。
这是我的RetrofitActivity.java
package com.example.dinesh.basicfragments;
import android.os.Bundle;
import android.view.Window;
import android.widget.TextView;
import android.widget.Toast;
import com.octo.android.robospice.persistence.DurationInMillis;

public class RetrofitActivity extends BaseSampleSpiceActivity{
private TextView mTextView;
private SampleRetrofitSpiceRequest githubRequest;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.spice_activity);
mTextView = (TextView) findViewById(R.id.spice_tv);
githubRequest = new SampleRetrofitSpiceRequest("octo-online","robospice");
}
@Override
protected void onStart() {
super.onStart();
getSpiceManager().execute(githubRequest,"github", DurationInMillis.ONE_MINUTE,new ListContributorRequestListener());
}
private class ListContributorRequestListener implements com.octo.android.robospice.request.listener.RequestListener<Contributor.List> {
@Override
public void onRequestFailure(SpiceException e) {
e.printStackTrace();
Toast.makeText(RetrofitActivity.this,"Failure Buddy",Toast.LENGTH_LONG).show();
}
@Override
public void onRequestSuccess(Contributor.List contributors) {
Toast.makeText(RetrofitActivity.this,"Success Buddy",Toast.LENGTH_LONG).show();
updateContributors(contributors);
}
}
private void updateContributors(Contributor.List contributors) {
String originalText = "RoboSpice Contributors : ";
StringBuilder builder = new StringBuilder();
builder.append(originalText);
builder.append('\n');
builder.append('\n');
for (Contributor contributor : contributors) {
builder.append('\t');
builder.append(contributor.login);
builder.append('\t');
builder.append('(');
builder.append(contributor.contributions);
builder.append(')');
builder.append('\n');
}
mTextView.setText(builder.toString());
}
}
SampleRetrofitSpiceRequest.java

this.owner=owner;
this.repo=repo;
}
@Override

Ln.d("Call Web Service");
return getService().contributors(owner,repo);
}
}
BaseSampleSpiceActivity.java
package com.example.dinesh.basicfragments;

spiceManager.start(this);
super.onStart();
}
@Override
protected void onStop() {
spiceManager.shouldStop();
super.onStop();
}
protected SpiceManager getSpiceManager() {
return spiceManager;
}
}
接口GitHub.java
package com.example.dinesh.basicfragments;
import java.net.URLEncoder;
import retrofit.http.EncodedPath;
import retrofit.http.GET;
import retrofit.http.Path;
public interface GitHub {
@GET("/repos/{owner}/{repo}/contributors")
Contributor.List contributors(@Path("owner") String owner, @Path("repo") String repo);
}
SampleRetrofitService.java

@Override

}
@Override

package com.example.dinesh.basicfragments;
import java.util.ArrayList;
public class Contributor {
public String login;
public int contributions;
@SuppressWarnings("serial")

如何解决呢?
最佳答案
实际上,问题在于该名称不存在任何回购。因此,我通过“ stephanenicolas”而不是“ octo-online”作为参数。
