Pylogix/Kivy/Buildozer APK issue #137

Closed pmpn8ez closed 4 years ago

pmpn8ez commented 4 years ago

Type of issue

Description of issue

Trying to get PyLogix working in an android app using Kivy / Buildozer Seems to crash the second i try to read. Works FANTASTIC (great job dude!!) in windows/ as a compiled exe and as python, also in the android app Pydroid 3 as a python file. The second i compile it into an APK it seems to break it.

Expected behavior

Should read the PLC as it does in windows

Actual behavior

Crashes app on first read

Code

Just simply trying: from pylogix import PLC

clx = PLC('192.168.2.190',2) read = clx.Read('tag')

works in every way until i pack it into an APK using buildozer

buildozer spec has pylogix as a requirments Any suggestion on what it needs to be happy?

Versions

Include versions to

Hey there, might wanna check out the crash logs for your android app or setup a debug session to live monitor it.

If I was to guess, apk packaging is not importing pylogix properly. Or if is packaging properly, is crashing due to unable to connect to the PLC, could be permissions on the manifest too.

Best thing to do here, is to make sure this code has a try/catch and that you log everything so that you can read the logs. Or just hook up phone to laptop and setup an adb debug session that way.

try:
    from pylogix import PLC
except Exception as e:
    # log here, exit program if pylogix module not found

try:
    clx = PLC('192.168.2.190',2)
    read = clx.Read('tag')
except Exception as e:
    # log here

With all that being said, this is not a pylogix issue.

Pretty sure the import works as the app doesn't crash right away, Happens on the read. I tried looking at the logs through buildozer/adb and they were so huge i couldn't spot were the app crashed, have to try again. In the 'build' folder for the app I do see the packager is downloading pylogix anyway.

For permissions, is there a wifi access permission to send/recieve data? that cold be a cause...

I'll try the try/catch and see what i can come up with.

I am very aware its not a pylogix thing, just wondering if anyone has any ideas or have tried making an APK with it. Like I said, i am a PLC guy and love tinkering with things like this. The simplest way I have ever seen to get info from a plc to a PC. I have made pretty extensive things in VB with OPC and DCOM, excel with DDE and with AdvancedHMI and that took a lot more work.

Not judging your knowledge or experience, I just made that note, because you might get better answers with kivy/bulldozer community. Most people here are plc guys including myself with a little bit of android experience.

Nice, so import is good. Then crash is most likely a permission assuming both phone and plc are on the same subnet.

Have a look here https://developer.android.com/training/basics/network-ops/connecting I don't know if there is a special permission for wifi, but with the try/catch hopefully it logs it. Written a few apps with Java/Kotlin you could use the logging library to see issues like this, you would see permission issues easy. I don't know if you can do it with kivy/buildozer though.

Regarding the logs you should be able to filter them.

kodaman2! You are a Lifesaver!!! That was it. just had to add INTERNET to the buildozer.spec file to add the access to the network. Now it works in linux/windows/python and android. Tried with my small project then was able to get a much larger program functioning with the same change.
