okhttp的2.6.0版本

使用https 链接接口时  执行 cancel()  会引发应用crash

暂时解决办法 是  把cancel() 放在background线程执行

okHttpClient.getDispatcher().getExecutorService().execute(new CancelRunnable        (requestTag, okHttpClient));

public class CancelRunnable implements Runnable {    Object requestTag;    OkHttpClient okHttpClient;    public CancelRunnable(Object requestTag, OkHttpClient okHttpClient) {        this.requestTag = requestTag;        this.okHttpClient = okHttpClient;    }    @Override    public void run() {        if (okHttpClient != null && requestTag != null) {            okHttpClient.cancel(requestTag);        }    }}
