java - An error occurred while connecting to camera: 0 --- Fail to connect to camera service -


i have phone specific problem when open camera on 1 particular nexus 5. an error occurred while connecting camera: 0 --- fail connect camera service error. on @ least dozen other phones works fine. other apps use camera on nexus 5 not crashing (indicating not apps can't access camera, mine).

there number of other questions on , have tried of them. talk missing permissions, , making sure camera destroyed after use.

to clear manifest requests , uses camera properly:

<uses-permission android:name="android.permission.camera" /> <uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera2" />

and releasing camera when destroying:

public void releasecamera() {     if (_camera != null)     {         _camera.stoppreview();         _camera.setpreviewcallback(null);         _camera.release();         _camera = null;     }      _surfaceholder.removecallback(this); }

can think of reason what-so-ever getting this. have suspicion theres sort of bug because using camera , not camera2 wild guess. reading updates api 6.0 there section on camera says:

in release, model accessing shared resources in camera service has been changed previous “first come, first serve” access model access model high-priority processes favored.

again without re-writing entire app use camera2 (not option) can't what's going on.

here code open camera (and works on every other phone except nexus 5)

private void setinitialcamera() {     try     {         if (_isbackfacing == true)         {             _camera = camera.open(0);         } else         {             _camera = camera.open(1);         }     } catch (runtimeexception e)     {         log.d("runtime exception","error " + e);         e.printstacktrace();     } catch (exception e)     {         log.d("camera error: ", " android unable tell error was");         e.printstacktrace();     } }

so looks culprit has something 6.0.1 update phone went through.

while didn't happen on other phones, did on failing nexus 5.

what happened 6.0.1 update allows users set individual permissions app. somehow persmission camera toggled off. turning on fixed issue.

to there go settings -> apps -> [app name] -> permissions

java - pagination of xlsx file to XSSFworkbook using apache POI -

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
