android - Accessing app content provider from wearable -


i working on udacity wearable course , unable wearable emulator send dataevents wearable device.

on both handheld , wearable have services extend wearablelistenerservice (wls). handheld version started via startservice call in activity, wearable service started in watchface service startservice, both services can seen started.

the device wls makes call content provider , attempts @ sending data wearable, putdataitem resultcallback never called.

the wearable seems paired phone receive various notifications on phone, setup good. both handheld , wearable modules have service added manifest required intent-filter, , logging can see both starting expected.

i following docs, must missing something.

thanks help.

handheld service

public class weatherdataservice extends wearablelistenerservice implements googleapiclient.connectioncallbacks, googleapiclient.onconnectionfailedlistener {      private static final string tag = "handheldservice";     private googleapiclient mgoogleclientapi;      @override     public void oncreate() {         super.oncreate();          log.d(tag, "initializing");         mgoogleclientapi = new googleapiclient.builder(this)                 .addapi(wearable.api)                 .addconnectioncallbacks(this)                 .addonconnectionfailedlistener(this)                 .build();         mgoogleclientapi.connect();     }      @override     public void onpeerconnected(node peer) {         super.onpeerconnected(peer);         log.d(tag, "onpeerconnected: " + peer.getdisplayname());          string[] temps = getcurrenttemps();          if (temps != null && temps.length == 2) {             log.d(tag, string.format("onpeerconnected: temps %s %s", temps[0], temps[1]));             notifywearables(mgoogleclientapi, temps[0], temps[1]);         }     }      private void notifywearables(googleapiclient client, string low, string high) {         log.d(tag, string.format("notifywearables: %s %s", low, high));         putdatamaprequest map = putdatamaprequest.create("/weather");         map.getdatamap().putstring("templow", low);         map.getdatamap().putstring("temphigh", high);          putdatarequest request = map.asputdatarequest();         wearable.dataapi.putdataitem(client, request).setresultcallback(new resultcallback<dataapi.dataitemresult>() {             @override             public void onresult(dataapi.dataitemresult result) {                 log.d(tag, string.format("onresult, %s", result.getstatus().getstatusmessage()));                 if (!result.getstatus().issuccess()) {                     log.d(tag, "onresult: failed send data");                 }             }         });        ... }

wearable service

public class weatherdataservice extends wearablelistenerservice {      private static final string tag = "wearable:service";      @override     public void oncreate() {         super.oncreate();         // called         log.d(tag, "oncreate");     }      @override     public void ondatachanged(dataeventbuffer dataevents) {         // never makes here         log.d(tag, "ondatachanged: ");         (dataevent dataevent : dataevents) {             log.d(tag, "ondatachanged: " + dataevent.getdataitem().geturi().getpath());             if (dataevent.gettype() == dataevent.type_changed) {                 log.d(tag, "ondatachanged: type_changed");                 datamap datamap = datamapitem.fromdataitem(dataevent.getdataitem()).getdatamap();                 string path = dataevent.getdataitem().geturi().getpath();                 if (path.equals("/weather")) {                     log.d(tag, "ondatachanged: /weather");                     string templow = datamap.getstring("templow");                     string temphigh = datamap.getstring("temphigh");                      log.d(tag, "ondatachanged: " + templow + " " + temphigh);                 }             }         }     } }

update

i missing mgoogleapiclient.connect() method call. putdataitem resultcallback being called, unforunately wearable device's ondatachanged event not being called.

ondatachanged

doesn't call because doesn't change data sent wear every time(it's call when data did change), try send different data , work, , make sure connect mgoogleclientapi in onstrart();

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). ...
