Android Studio Gyroscope examples? -


i'm trying build application desired affect when device tilted degree.

i've taken at, , enabled, accelerometer, doesn't give me desired affect. said, wish device want to, when device has achieved degree, 90 degrees.

i've got following code, works when device tilted fast enough:

@override public void onsensorchanged(sensorevent sensorevent) {     sensor mysensor = sensorevent.sensor;     if (mysensor.gettype() == sensor.type_gyroscope) {         float x = sensorevent.values[0];         float y = sensorevent.values[1];         float z = sensorevent.values[2];          long currtime = system.currenttimemillis();          if ((currtime - lastupdate) > 100) {             long difftime = (currtime - lastupdate);             lastupdate = currtime;              float speed = math.abs(x + y + z - last_x - last_y - last_z) / difftime * 10000;              if (speed > shake_threshold && !sound.isplaying()) {                 sound.start();             }              last_x = x;             last_y = y;             last_z = z;         }     } }

this code used accelerometer, changed sensor.type_accelerometer sensor.type_gyroscope, hoping reveal me do.

could possibly somethings this?

if (x > 90 || y > 90 || z > 90 && !sound.isplaying()) {     sound.start(); }

in place of my

if (speed > shake_threshold && !sound.isplaying()) {     sound.start(); }

i've tried looking examples of how this, unable find anything, on android developers...

i want simple allow me tell when device has reached degree or radian, speed not matter.

any wonderful.

thanks!

edit:

i've done this:

 if (z > 5 || z < -5 || x > 5 || x < -5 && !sound.isplaying()) {      sound.start();  } else if ( z == 4 || x == 4) {      sound.stop();      sound = mediaplayer.create(this, r.raw.sound);  }

and works extent. once z , x values have crossed threshold of '5', sound play. but, if leave device in position, then, upon returning device starting position activates sound again, because still within '5' threshold.

this not looking for, figured try little different:

if (z == 5 || z == -5 || x == 5 || x == -5 && !sound.isplaying()) {     sound.start(); } else if ( z == 4 || x == 4) {     sound.stop();     sound = mediaplayer.create(this, r.raw.sound); }

this doesn't work @ all.

i want device able detect when has crossed threshold of '5', not want able start sound again if moved , still inside of threshold.

basically, want device able play sound when line crossed, , not when point after line. figured having when number == 5 it, can't seem that.

the stop function doesn't work @ either. if use == @ all, doesn't work. there way can code java able recognize?

remember, want able know when point crossed, not when area entered.

cheers!

accelerometer: "measures acceleration force in m/s2 applied device on 3 physical axes (x, y, , z), including force of gravity."

orientation: "measures degrees of rotation device makes around 3 physical axes (x, y, z). of api level 3 can obtain inclination matrix , rotation matrix device using gravity sensor , geomagnetic field sensor in conjunction getrotationmatrix() method."

apache - PHP Soap issue while content length is larger -

we have developed soap based webservice post data third party webservice. accepts 4 params. in 1 of parameters accepts xml string no size limit restriction put in place. the webservice works fine in local environment running on php 5.2 , apache2. works content length long 10 mb. in staging server running nginx , php fpm.we have updated max post size , max upload filesize in php.ini , client_max_body param in nginx.conf allow upto 50 mb. but webservice client keeps on loading in staging environment. gives 502 timeout , gives soap error. can me understand issue here?

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
