 # Repo allowing -in a KISS way- to create a containered way to build an Android App APK
 
+## brach `no-res.xml`
+
+this branch features the exmaple.app to not require the compoletely bogus unneeded requirement
+to setup a `./apk/res/layouts/res.xml` file to setup the layout to be used. 
+Instead a layout is created inline
+
+
 ## tl;dr
 
-to build an application
+to `make` minimal exmaple.app via the docker-compose:
+```
+# clone repo
+git clone https://git.alexmahr.de/lion/android-app-docker
+# enter local copy
+cd android-app-docker
+# checkout the branch for minmal-example-app
+git checkout minimal-example-app
+# set env variable
+export YESACCEPT=y #to acceccpt the license agreement terms (it is your responsibility to read it)
+# build app (this involves first building the docker compose setup and container used to build the apk)
+make build
+```
+
+This will generate the APK file `./apk/example.app.apk`
+
+this can be installed via `adb`
+```
+adb install -r ./apk/example.app.apk 
+# or alternative type
+make install
+```
+which of course would require your mobile device to be connected and setup for USB-debugging.
