Bug? What is "_vvvvvvvvvvvvvvvvvvvvvvvvvvv2" event?

I am using Firebase Analytics. For my app, it has logged a crash as shown below.

But I can't figure out what the event/log line with the "_vvvvvvvvvvvvvvvvvvvvvvvvvvv2" means. Does anyone have an idea?

B4a Obfuscation

You should post questions in the questions forum.

The answer is straight-up in your question:

com.omnisoft.voiceit.main._vvvvvvvvvvvvvvvvvvvvvvvvvvv2 (main.java:1509)

On your project folder, open "Objects/src/com/omnisoft/voiceit/main.java" with Notepad++.
Scroll down to line 1509. In the comment above, check which B4A line is causing trouble.

Moreover, here's some stack overflow, given by googling "setDataSourceFD failed".

Good luck!

A file named ObfuscatorMap.txt will be created under the Objects folder. This file maps the original identifiers names to the obfuscated names. This mapping can be helpful to analyze crash reports.
