我知道这已被问过几次，但我面临一个问题。 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。 即使我正在生成一个调试apk并运行应用程序，它工作正常。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
然而，在生成签署过的APK的应用程序，我提示以下错误：发布：
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)

我无法揣摩出此异常发生，为什么？
请问谁能帮忙？
我已经通过几个环节去为：
我打电话给我的异步任务为，
new BannerAdAsyncTask().executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
我的异步任务是，
// Checking banner ad and displaying the appropriate banner ad
class BannerAdAsyncTask extends AsyncTask<String, Boolean, Boolean> {
String addUserResponseCode;
String responseForAdduserRequest;
String msg;
/*
* (non-Javadoc)
*
* @see android.os.AsyncTask#onPreExecute()
*/
@Override
protected void onPreExecute() {
super.onPreExecute();
}
/*
* (non-Javadoc)
*
* @see android.os.AsyncTask#doInBackground(Params[])
*/
@Override
protected Boolean doInBackground(String... params) {
try {
String fetchBannerURL = context.getString(R.string.site_url)
+ "fetchbannerad.cfc?method=fetchbannerad";
responseForAdduserRequest = fetchContentFromServer(fetchBannerURL);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
/*
* (non-Javadoc)
*
* @see android.os.AsyncTask#onPostExecute(java.lang.Object)
*/
@Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
try {
if (responseForAdduserRequest != null) {
// Parse JSON
JSONObject pages = new JSONObject(responseForAdduserRequest);
String d = pages.getString("DATA");
JSONArray dd = new JSONArray(d);
int len = dd.length();
for (int i = 0; i < dd.length(); i++) {
String p = dd.getString(i);
JSONArray values = new JSONArray(p);
adFileName = values.getString(6);
adLinkLocation = values.getString(7);
}
adBanner.setVisibility(View.VISIBLE);
adBanner.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// If the link location contains the companyid field,
// fetch the company id and navigate to the app's
// companies page with this id
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) {
isNumber = false;
}
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响应，
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;
}
