BufferedInputStream is closed when setting postDelayed Runnable

I have my GameActivity that is a simple quiz. I set up two Runnables, mRunnableQuestion and mRunnableQuestionWithPenalty. The logic is: mRunnableQuestion shows new question and waits 30 seconds, when user doesn't answer in this time, the other Runnable is called, which gives user points penalty:
private Runnable mRunnableQuestion = new Runnable() {
#Override
public void run() {
new AsyncAPIGetQuestion().execute(mCategoryId);
mHandler.postDelayed(mRunnableQuestionWithPenalty, 30000);
}
};
Of course, when user answers in time, I give user points and restart the Runnable:
mHandler.removeCallbacksAndMessages(null);
mHandler.post(mRunnableQuestion);
It works very well. However, I wanted to color the Cards based on correct/wrong answer and wait 5 seconds. So i changed code above to:
mHandler.removeCallbacksAndMessages(null);
colorAnswers();
mHandler.postDelayed(mRunnableQuestion, 5000);
This is where the problem begins. When I run my app, after 2, 3 or 4 questions I get a EOF/BufferedInputStream error:

It ONLY happens, when I add the extra postDelayed() there. No problems before.
My doInBackground part of AsyncTask that is executed by Runnable and that returns an error as stated above
#Override
protected JSONArray doInBackground(String... params) {
JSONParser jParser = new JSONParser();
JSONArray json = jParser.getJSONFromUrl(apiURL);
return json;
}
And the JSONParser.getJSONFromURL:
public JSONArray getJSONFromUrl(String urlSource) {
try {
URL url = new URL(urlSource);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setChunkedStreamingMode(0);
inputStream = new BufferedInputStream(urlConnection.getInputStream());
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
if(!reader.ready()) {
break;
}
}
inputStream.close();
json = sb.toString();
} catch (Exception e) {
Log.e(TAG, "Error converting result " + e.toString());
}
try {
jArr = new JSONArray(json);
} catch (JSONException e) {
Log.e(TAG, "Error parsing data " + e.toString());
}
return jArr;
}
I would really appreciate any help. All the best!

It looks like I solved this issue.
The problem was in my jParser.getJSONFromUrl() method, specifically these lines:
URL url = new URL(urlSource);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setDoOutput(true);
It seems that you only set setDoOutput parameter as true, when you are using POST/PUT requests. If you want only perform a GET request, such as in my case, you should set it as false:
urlConnection.setDoOutput(false);
Otherwise, you can end up getting errors as described above.
Best regards to the Community!

How to solve this error/issue? It shows null in website description .

Looks like there is an error in URL connection. Are you not passing valid URL?
Caused by: java.lang.IllegalArgumentException: Must supply a valid URL

Getting a crash on doInBackground() line on client.execute(httpGet). Why?

Crash is: java.lang.RuntimeException: An error occured while executing doInBackground()
Why I am getting a crash on the HttpResponse response = client.execute(httpGet); line here? Does it have something to do with my ThreadPolicy?
From my fragment I call this:
new ReadJSONFeedMainTask().execute(urlString);
....
private class ReadJSONFeedMainTask extends AsyncTask<String, Void, String> {
protected String doInBackground(String... urls) {
return Helper.readJSONFeed(urls[0]);
}
protected void onPostExecute(String result) {
// do stuff
}
}
}
Then it's called here:
public static String readJSONFeed(String URL) {
ThreadPolicy tp = ThreadPolicy.LAX;
StrictMode.setThreadPolicy(tp);
String numberValue = URL.replaceAll(" ", "%20");
StringBuilder stringBuilder = new StringBuilder();
HttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(numberValue);
try {
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(content));
String line;
while ((line = reader.readLine()) != null) {
stringBuilder.append(line);
}
} else {
Log.e("JSON", "Failed to download file");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return stringBuilder.toString();
}

I had the same problem after updating from BugSense to Splunk Mint and there was nothing wrong with my code. After I commented out Splunk.init(...) method invocation everything started to work again. Problem was occuring only on HTC devices and with Splunk Mint enabled - all calls of HttpClient#execute() method were throwing DelegationException. Not sure if this is your case but maybe my answer will help someone with the same problem as mine.

It seems pretty clear, the end of the stack trace indicates Connection timed out. Your server is unreachable.

You should use Asynctask for any work with server, see http://developer.android.com/reference/android/os/AsyncTask.html

Can`t create and copy the file

My program should work as follows:
1.Copy the new database in the program folder
2.Import the records from the old database to the new one.
But I for some reason get an exception. Why?
protected Object doInBackground(Object[] objects) {
String LOCAL_DATABASE_PATH = getApplicationInfo().dataDir + File.separator +
"databases" + File.separator;
File fileDir = new File(LOCAL_DATABASE_PATH);
if (!fileDir.exists())
fileDir.mkdirs();
File tempFile = new File(LOCAL_DATABASE_PATH + DATABASE_NAME);
try {
tempFile.createNewFile(); // here I catch exception
InputStream is = SplashActivity.this.getAssets().open(
DATABASE_NAME);
FileOutputStream os = new FileOutputStream(new File(
LOCAL_DATABASE_PATH, DATABASE_NAME));
int bufferLength = 0;
byte[] buffer = new byte[2048];
while ((bufferLength = is.read(buffer)) > 0) {
os.write(buffer, 0, bufferLength);
}
Preferences.getInstance(SplashActivity.this).
set(Preferences.IS_DATABASE_COPYING_ON_DEVICE, true);
is.close();
os.close();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
I am getting the following error

When creating the tempFile try using the fileDir you already created to get sure it exists.
File tempFile = new File(fileDir, DATABASE_NAME);
Before you create a new file you should check if it already exists by calling its exits() method. And then instead of opening it again you should actually keep on using it. Or at least close it before opening again.
if(!tempFile.exists())
tempFile.createNewFile();
InputStream is = SplashActivity.this.getAssets().open(
DATABASE_NAME);
FileOutputStream os = new FileOutputStream(tempFile);
Create you FileOutPutStream using the tempFile or close tempFile to get sure your file is not locked.

Telegram Java API- socket connection issue [duplicate]

This question already has answers here:
Error message 'java.net.SocketException: socket failed: EACCES (Permission denied)'
(10 answers)
Closed 8 years ago.
I'm trying to use Telegram Java API https://github.com/ardock/telegram-api
and I started with some simple RPC call:
SampleApiState apiState = new SampleApiState(connections);
TLRequestAuthCheckPhone checkRequest = new TLRequestAuthCheckPhone("+1234567890");
TelegramApi api = new TelegramApi(apiState, new ApplicationInfo(),
new ApiCallback() {
#Override
public void onUpdatesInvalidated(TelegramApi api) {
// TODO Auto-generated method stub
Log.i(TAG, "onUpdatesInvalidated");
}
#Override
public void onAuthCancelled(TelegramApi api) {
// TODO Auto-generated method stub
Log.i(TAG, "onAuthCancelled");
}
#Override
public void onUpdate(TLAbsUpdates updates) {
// TODO Auto-generated method stub
Log.i(TAG, "onUpdate");
}
});
TLCheckedPhone checkedPhone = api.doRpcCall(checkRequest);
And here is log:

After connection failure, it tries to connect again and again, but not very successfully. I couldn't find out what's the reason and how to solve this problem. Maybe someone had same problem? Will be very gratefull for some help)

From the exception you posted it seems it is an android app and this is a permission problem.
java.net.SocketException: socket failed: EACCES (Permission denied)
Try to add this to the manifest file:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
