-# Ideas and todos
-
-## 1. EMULATOR: enable a way to have the "sdk emulator" running 
-
-this is attempted in the `emulator` branch. Challenges comprise:
-
-* Xorg server must be forwarded (and other stuff like sound etc)
-* the emulator itself might need to have `docker .... --device` setup for `/dev/kvm` probably (and at that point it might be
-  better to have it all run natively inside a VM anyways... (alternative would be nested virutalization) 
-
-
-## 2. BUILD and PACKAGENAME improvements
-
-### status quo: 2 Makefiles (gnu make) are involved, 
-* a) one being the outer one that uses Makefile.apps as an include and then
-* b) an inner one located at `./apps/<app-name>/Makefile`
-
-the inner-one is not "parametrized" and at present has explicit nameing of the android app/ package (i.e. `example.app`), 
-which comes with the additional negative that one has several files that need to be adjusted, this also being true 
-because of the "fun that JAVA" naming conventions which basically means that the very least those files all have to
-be kept in sync
-
-* `./apps/<app-name>/AndroidManifest.xml` 
-* `./apps/<app-name>/Makefile` 
-* `./apps/<app-name>/src/<package-name>/<activity-name>.java`
-
-### goal: attempt to have the `<app-name>`, `<package-name>` and `<package-name>` be abstracted
-
-Ideally make the inner Makefile superfluous
-
-
-## 3. ALLOW KOTLIN
-
-Since Java was apparently not "good/fancy" enough of maybe "bloated" the hippster did do what they like best
-re-invent to garnish personal "pride/achievement" and thus make a unhelpful thing (java) into now 2 unhelpful
-things (i.e. Kotlin and Java) super! 
-However oftentimes now the undesired-yet-existing-kotlin is there and a goal could be to enable it being used.
-After all it appears to be a tiny bit less of a boilerplate annoyance...
-
-## 4. ALLOW GRADLEBUILDS
-
-GRADLE is often used as a building system for apps, it would be beneficial to have those build run also 
-in this `android-docker-app` thing
