There is no harm in inline java code. In fact many default libraries have some inline java code. There is no speed loss etc.

In the Netherlands we have a proverb that reads: "Where the emperor is not, he loses his rights". The only way to access a specific dialer is using inline Java. In addition, it also dawns on Android designers that all kinds of things such as a dialer can be misused by malicious people.
Finally, in a similar question, Erel wrote this However, if you read the documentation you will see that it will not work on Android 10+ devices
I'm afraid that your and no direct B4A function is to use/misuse underlying dialer hardware and that you run into all kinds of security rules that you might be able to make work for a short time after deep research via some "hacks" or very heavy tweaking. Perhaps it is more convenient to ignore the dialer and look for another solution?

Then give the error log (in text) so that experts can suggest some solution

Based on the EXPERT Erel

However, if you read the documentation you will see that it will not work on Android 10+ devices

Perhaps the Android 10+ devices were the app is stopped and app crashed?
