AsyncHttpClient运行出错,求助

AsyncHttpClient client = new AsyncHttpClient();
运行到这一句之后就闪退,有没有大佬知道是怎么回事?
以下是这个片段的代码:

public void sendAsyncHttpClient(String string){
        try{
            String path="http;//192.168.1.1";
            AsyncHttpClient client = new AsyncHttpClient();
            RequestParams params=new RequestParams();
            params.put("data",string);
            client.post(path, params, new AsyncHttpResponseHandler() {
                @Override
                public void onSuccess(int i, Header[] headers, byte[] bytes) {
                    Toast.makeText(NFCmain.this, "Onsuccess", Toast.LENGTH_SHORT).show();
                    log.e("onSuccess",new String(bytes));
                }

                @Override
                public void onFailure(int i, Header[] headers, byte[] bytes, Throwable throwable) {
                    Toast.makeText(NFCmain.this, "OnFailure", Toast.LENGTH_SHORT).show();
                }
            });
        }catch(Exception e){
            e.printStackTrace();
        }

    }

我现在也遇到了这个问题，请问你解决了吗？
