Question

我知道之前曾多次询问过这个问题，但我遇到了一个问题。当我将设备连接到系统并运行我的应用程序时它工作正常。即使我正在生成调试apk并运行应用程序，它也能正常工作。

但是，在为应用程序发布生成已签名的apk时，我收到以下错误：

FATAL EXCEPTION: AsyncTask #5
Process: com.xxxx.xxxxx, PID: 8180
java.lang.RuntimeException: An error occurred while executing doInBackground() at android.os.AsyncTask$3.done(AsyncTask.java:309)

at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:588)
at java.lang.Thread.run(Thread.java:818)

我无法弄清楚这个异常发生在哪里以及为什么？

拜托，有人可以帮忙吗？

我已经通过以下几个链接：

我将异步任务称为

new BannerAdAsyncTask().executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);

我的异步任务是，

            String d = pages.getString("DATA");

            JSONArray dd = new JSONArray(d);

                    if (adLinkLocation.contains("?companyid=")) {

                        int temp = adLinkLocation.indexOf("companyid=");

                        temp = temp + 10;

                        String companyid = adLinkLocation.substring(temp);

                        boolean isNumber = true;

                        try {

                            int id = Integer.parseInt(companyid);

                        } catch (NumberFormatException e) {

                        if (isNumber) {

                            Intent intent = new Intent(context,
                                    CompanyProfile.class);
                            intent.putExtra("company_id",
                                    Integer.parseInt(companyid));

                            // Get company branches as a cursor
                            final DataAdapter mDbHelper = new DataAdapter(
                                    context);
                            mDbHelper.createDatabase();
                            mDbHelper.open();

                            intent.putExtra("branch_id", primaryBranchID);
                            intent.putExtra("com_name", name);
                            intent.putExtra("com_tradename", tradename);
                            intent.putExtra("com_desc", "");
                            intent.putExtra("main_branch_id",
                                    primaryBranchID);

                            mDbHelper.close();

                            context.startActivity(intent);
                        }

                    } else {

                        // Otherwise load the link in browser
                        Intent intent = new Intent(
                                "android.intent.action.VIEW", Uri
                                .parse(adLinkLocation));
                        startActivity(intent);
                    }
                }
            });
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

这是我从服务器获取内容的方法的代码。我怀疑这个问题在这里得到了回应，

    private static String fetchContentFromServer(String request) {

    /* Converting required variables to convert the response */
    String line = "";
    String responseString = "";

    /* Initializing the HTTP client */
    HttpClient httpClient = new DefaultHttpClient();

    try {

        /* Read and write connection timeout */
        HttpParams httpParameters = new BasicHttpParams();

        int timeOutInMillis = 8 * 1000;
        HttpConnectionParams.setConnectionTimeout(httpParameters,
                timeOutInMillis);

        int socketTimeOutinMillis = 8000;
        HttpConnectionParams.setSoTimeout(httpParameters,
                socketTimeOutinMillis);

        /*
         * Getting the response by giving request and adding it to the
         * buffer reader to read the content
         */
        HttpResponse httpResponse = httpClient
                .execute(new HttpGet(request));
        InputStream inputStream = httpResponse.getEntity().getContent();
        BufferedReader bufferedReader = new BufferedReader(
                new InputStreamReader(inputStream));

        /* For all the lines in the response */
        while ((line = bufferedReader.readLine()) != null) {

            /* Appending every line to the result */
            responseString += line;
        }

        /* Closing the input stream and displaying result in text view */
        inputStream.close();

    } catch (Exception e) {

        e.printStackTrace();
    } finally {

        /* Closing the http connection */
        httpClient.getConnectionManager().shutdown();
    }

    return responseString;
}

我的案例中的问题是，在生成发布APK后我没有得到任何类型的服务器响应，而在调试APK的情况下，所有服务器响应都很好。

我在gradle文件中添加了以下行，

    buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }

应用程序在调试模式下工作，但崩溃与发布apk显示java.lang.RuntimeException：Android
