android apk is crashing after displaying splash screen on phone #2030

Can you post your code as well? That will make it easier to figure out what exactly is going wrong. Also if you call log cat with grep you can get more concise logs: |
Thanks for the command for fine grained logs view of logcat. But this doesn't include complete log lines as many logs are not tagged with python which are of the app. As requested following is the python code file with name main.py: |

that's already the case, it just wasn't rendering properly, i edited their post to fix it. interesting part of the log seems to be crash in sdl initialisation? would be nice to know which function was called at this point, building p4a in debug mode could help to get the symbols. |
|
Anyway, my guess is that one of the libraries was incorrectly built because not all dependencies were present, and cleaning up ( |
I did not actually understand your point. I have already used if name == 'main': in the code of app. I have gone through the link but found no clue of what you are referencing. |
HI, I am unable to figure out the edited patr in the post which you have mentioned in the comment to fix the issue. Kindly highlight the edited part. |
Hi, I have removed .buildozer dir and then try re-building the apk but no it is still crashing after displaying the default splash screen of the app. Kindly help me out. |
This is the crash, it's not in python, it's in C, and it doesn't give a lot of information, it would require investigation with a debugger with a debug build to understand, which is not really to step you through. So i'm curious about your list of requirements
Did you add all that because of specific problems? Did you have the same or different issues before that? because a much shorter list should be enough.
I don't know if you think it's polite to say that, but that's not how i read it, we are already kindly helping you out, no need to insist on that. |
Yes! I understand that crash logs are of C not python might be because of the cythonizing while building. There is nothing special for using huge requirements. I was just trying with different options. I also build with requirements = python3, kivy but the issue is same with that too. I am stuck at this since a month almost and trying and trying to build successful apk |
I identified that I have used double quotes ("") and you have mentioned single quote to enclose main. I tried with this too but the problem remain. Guide further to resolve. |
|
I think he was mentioning the underscore |
|
A pygame user has the exact same problem, with the pygame fork of p4a, but it happens only on a mac, and can't be reproduced on Linux. |
Yes! I am still trying with double quotes itself and more than 100 times with different versions as per follows: I am able to build app successfully and installed on Samsung Galaxy A5 (2016). It is crashing on run. Building environment: buildozer.spec: requirements python3,kivy libs in APK: crash logcat error: |

same problem, but after many taps on screen while app is loading, application starts successfully. |

What I noticed was that kivy projects were building well, but kivymd projects were crashing after the splashscreen. This worked for me

Closing as a support issue that's got out of control. |

Description
I am building basic python android app using buildozer and p4a and able to successfully build the apk. The build apk has been installed successfully over the usb connected MI Redmi phone and it runs. After splash screen the app crashes and found no clu of cause of crash in logcat logs.
