+# 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

 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
