okhttp cancel() 导致Crash NetworkOnMainThreadExcepti

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);
        }
    }
}
