android - Paho MQTT AlarmPingSender wakelock stucked -

-

i using paho android service project (app name sealer). (link)

i've tested 22 hours , result has brought me strange result.

it seems app keeps awake cpu long time (~10,5 h).

i've searched in source code wakelock tag , found wakelock tag belongs alarmpingsender class. has met problem ever ?

i didn't modify android service source code, it's original.

i've attached screenshots (hangouts , viber comparison).

edit 1.

there code snippet source code:

    mqttoptions = new mqttconnectoptions();     mqttoptions.setcleansession(false);     // defaultkeepalive 240     mqttoptions.setkeepaliveinterval(constants.defaultkeepalive);

edit 2

i think relevant code android service source code:

/*  * class sends pingreq packet mqtt broker  */ class alarmreceiver extends broadcastreceiver {     private wakelock wakelock;     private string wakelocktag = mqttserviceconstants.ping_wakelock             + that.comms.getclient().getclientid();      @override     public void onreceive(context context, intent intent) {         // according docs, "alarm manager holds cpu wake lock         // long alarm receiver's onreceive() method executing.         // guarantees phone not sleep until have         // finished handling broadcast.", class still         // wake lock wait ping finished.         int count = intent.getintextra(intent.extra_alarm_count, -1);         log.d(tag, "ping " + count + " times.");          log.d(tag, "check time :" + system.currenttimemillis());         imqtttoken token = comms.checkforactivity();          // no ping has been sent.         if (token == null) {             return;         }          // assign new callback token execute code after pingresq         // arrives. wakelock receiver has one,         // release until ping response returns.         if (wakelock == null) {             powermanager pm = (powermanager) service                     .getsystemservice(service.power_service);             wakelock = pm.newwakelock(powermanager.partial_wake_lock,                     wakelocktag);         }         wakelock.acquire();         token.setactioncallback(new imqttactionlistener() {              @override             public void onsuccess(imqtttoken asyncactiontoken) {                 log.d(tag, "success. release lock(" + wakelocktag + "):"                         + system.currenttimemillis());                 //release wakelock when done.                 if(wakelock != null && wakelock.isheld()){                     wakelock.release();                 }             }              @override             public void onfailure(imqtttoken asyncactiontoken,                     throwable exception) {                 log.d(tag, "failure. release lock(" + wakelocktag + "):"                         + system.currenttimemillis());                 //release wakelock when done.                 if(wakelock != null && wakelock.isheld()){                     wakelock.release();                 }             }         });     } }

it seems (at least according screenshots) wakelock somehow 'stucked', doesn't released.

i have same problem , created bug report. please have further help: https://bugs.eclipse.org/bugs/show_bug.cgi?id=480134

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
