Hello, i connected my application with my ecu on the car, i can record the log on the radio, but i cant find the file, is there anyway i can go into android files to find it?
"my application"?
which application is that? Be clear in what you ask.
And whatever application it is, it is most probably saving its data either in its own /data/data/<packagename>/data folder or in its own sqlite database inside /data/data/<packagename>/. You will not be able to "touch" that as it is against security. Either "your application" has an export option, or you need to root your unit to get to the data.
