RA app for cultural heritage: problem with android

Hello.
I am developing a "openspace app" on android for a museum located in Italy (Legnago, VR).
I have a couple of questions:
1) I have exported my "app" to android and tried on two devices: a) my samsung galaxy 4 tab (tablet, with lollipop 5.0) b) my smartphone, Huawei p9 lite, with marshmallow 6.0
On my tablet the app install, but do not, apparently, seems capable to activate the camera: the screen, after the title "openspace loading" remain black.
On my smartphone all functions in the right manner, but, after ten or so minutes, with the app open (anche the camera active), the app crash (the screen locks itslef). I need to reboot the system to restart correctly the app.
What could be the problem?

I have another set of question (in reality, a whole bunch of them!), but I will leave them for later...

Regards, Damiano

Re: RA app for cultural heritage: problem with android

Hello,

it's hard to support all the devices, a lot of constructor do not manage correctly the camera drivers hmm
I have a shield tablet and a galaxy S7 for my tests.

can you test with a dev version of the android pack : https://svn.scolring.org/trunk/setups/a … ndroid.exe

and tell me if the problems remains or not.

Try to debug phone with Debug Monitor Server includes in Android Studio or instal loging app on phone. It can be memory leak

Re: RA app for cultural heritage: problem with android

Hello.
I have downloaded and installed your dev version.
But it send me the follow errors (see in image):
screen

I have send you a invitation to my dropox folder, because the app is bulky. In here you can find also the marker I have build for the app.

Re: RA app for cultural heritage: problem with android

ok so in order download and install :
- scolvoyager update : https://svn.scolring.org/trunk/setups/i … plugin.exe
- openspace3D update (unchek android so it will not replace the current one with the older : https://svn.scolring.org/trunk/setups/i … _setup.exe
- android pack update (if not already done) : https://svn.scolring.org/trunk/setups/a … ndroid.exe

So this beta / dev version add several new features :
- loading screen on android start a lot sooner
- on android export you can choose the app orientation (landscape / portait), this also manage
- the "application is not responding" should not show any more on android when you touch the screen on loading
- the ar capture plugit have a new parameter to set the device index (0 for default, 1 for face camera, also check mirror for this one on android)

Re: RA app for cultural heritage: problem with android

Hi!
I have installed everything and re-exported my project (with "architecture" default).
Unfortunately the problems have not been resolved :-(

1) on smartphone: after 20 minutes of smootly run the camera freeze and you have to restart the device.
OS    Android OS, v6.0 (Marshmallow)
Chipset    HiSilicon Kirin 650
CPU    Octa-core (4x2.0 GHz Cortex-A53 & 4x1.7 GHz Cortex-A53)
GPU    Mali-T830MP2

2) on my tablet it continues to not initialize the camera.
Do you think is a problem of the android version?
On the smartphone is the 6.0, on the tablet is 5.0.
Tecnical specification of my tablet (is a very standard table):
CPU / Processore    Qualcomm Snapdragon 400 APQ8026 / ARM Cortex-A7
Clock Processore / Core    1200Mhz 32bits Quad-Core
Memoria RAM    1,5GB
GPU Scheda Grafica    Qualcomm Adreno 305
Memoria Interna    16GB
Android Lollipop 5.02

Re: RA app for cultural heritage: problem with android

no idea hmm I think a coworker have a galaxy tab 4, I'll ask him if I could test on it.
I don't think this is relative to the android version I build binaries for 4.0.

try again on the tablet but remove the app on the tablet first to be sure it's updated, just in case ^^

Re: RA app for cultural heritage: problem with android

I am very sorry to trouble you, but perhaps I need to specify the idea (and the operational contest) behind this app.

We have a archeological museum, in Legnago (here the website), wich we want to "augment".

The RA spot, for now, are 9 in total. We programmed two visit: one very short, 30 minutes, and one long, 1 our and 15 minutes.

For the short visit we thinked to leave the app always running, to reduce the reboot time of the app; but now I am thinking:

1) if the app, for several reasons, do not remain active for more than 20 minutes...
2)... and the sperimentation with RA and educational purposes shows that it is more profitable and engaging, rather than one single application always active, to runs, on each spot, the right (how I can name it, "module"?) module...
3)... perhaps is more profitable to subdivide the project in nine "app"...

But:

1) there's the possibility to build an app that pulls togheter the nine apps?
2) or perhaps is better to build nine scenes in the same project (regard this matter, is even possible? I don't see, in the openspace software, the possibility to make several scenes in addition to the first) and runs them one after the other?

Sorry for the very annoyng and "talkative" post (and excuse me for my poor english)...

Regards, Damiano

Re: RA app for cultural heritage: problem with android

well from my point of view one app per spot is better for users. and yes it should be able to run continuously on tablets that charge faster than the battery draw.

but yes you can load / unload sub scenes in OS3D using the instantiate plugIT
check the demos and samples there is several use of instantiate plugit

Re: RA app for cultural heritage: problem with android

for the tab4 could you try to force the camera index to -1

plugit onInit.init -> capture.set active device : -1 in parameter

It remind me something ...

Re: RA app for cultural heritage: problem with android

Hello! Sorry for not responding to your kind suggestion, I have been away from internet for a while!

I will test right away; in the meanwhile I have new questions: but I think is best to open a new topic for them!

Thanks, Damiano

Re: RA app for cultural heritage: problem with android

Hello there!
I have tried with you suggestion, but with no luck :-(
The funny thing is that I have inserted a "screenshot button" and that button is displayed and working! In fact I can make a screen shot... but totaly black, beacause the camera is obsinated to remain closed (or whatever is the problem...).

I think is a problem on my device, at this point...
