I downloaded the opencv Android SDK for both 3.0.0 and 2.4.11. In the sdk samples, I put the prebuilt app example-camera-calibrate.apk onto my Moto Doird Turbo. It (v 2.4.11) runs (OBTW the one in 3.0.0 crashes on choosing calibrate) and appears to succeed in calibrating.

Where does it write the results file? What is the file name?

The source files suggest the file will be named out_camera_data.??? but the extension varies from .xml to .yml to .yaml.

I looked around in the usual places like /data, /app/data, ... and searched the entire sdcard.

My phone is now Android 5.1. Is there a new permissions thing with a missing "android.permission.WRITE_EXTERNAL_STORAGE" ?

Any help will be much appreciated.
