python kivy.app uses import yfinance convert to apk successfully, but apk is not opening in mobile.

[管志宏]

Dear Sir:

    I am new to both python and kivy. The attached code is work ok in Ubuntu VM. I created the apk file using buildozer and successfully. Then I installed my apk file in mobile and tried to open. I got the loading text with kivy logo but the app is closed immediately. Originally, the apk. Works ok without adding “ import yfinance as yf “, As there is no error, I pretty sure that import the yfinance module cause the apk failure.  Could you please help me how to edit the buildozer.spec to fix the problem. Thanks!

There are three attachments: 1. output from buildozer 2. main.py 3. buildozer.spec

Please use adb to catch the app log,  it is very useful.

Dear sir:

    Thank you very much for your help about telling me to use adb to catch apk executing log. I installed adb and run apk thru USB. I got error message from log file. I edit the buildozer.spec and add all the missing requirements from the log report. The problem was solved and the main page can be opened. I use the function of the ping IP that works OK. But I use the function of downloading data with yfinance module. The apk is down for all and even I can’t use the quit button to quit the apk. Enclosed here with  the log file and .py file. I can see the log file showing something related to “hostname=query2.finance.yahoo.com”(at time 10:20) and I am not quite understand the log file what is the reason to cause the apk failure. Please help me how to fix the problem. Thanks!

I don't know much

1) There is this 12-16 10:19:22.205 26041 26062 W linker : dlopen failed: "/data/data/org.test.takeinpdy/files/app/_python_bundle/site-packages/charset_normalizer/md.so" has unexpected e_machine: 62, retry

So try using chardet instead of charset-normalizer

2) Then search the log for     Traceback

There is some yfinace/pands issue - but I don't know anything about that.
