I have a crash in com.google.android.gms.vision.text.TextRecognizer.detect which I am trying to get some progress on. The crash is non repro; reported from field; by a very small percentage. Our code analysis and testing has not revealed anything. To make progress I was hoping to look at the library 'code'. Given that Android is open source, where can I possibly start looking for code that comprises the classes/libs given in the source code below?
The line 28328 pipeline.cc:208] Check failed: ValidateInputPreviewFrame is giving me some hope; that we can backtrace the source of our error.
