Could not find runtime.aar

[Rudloff]

While doing test for https://github.com/KillerInk/FreeDcam/issues/63, I stumbled on this error:

Could not resolve all files for configuration ':app:debugCompileClasspath'.
> Could not find runtime.aar (android.arch.lifecycle:runtime:1.0.3).
  Searched in the following locations:
      https://jcenter.bintray.com/android/arch/lifecycle/runtime/1.0.3/runtime-1.0.3.aar

If I have runtime-1.0.3.aar from another Android project, it works correctly. But if I clean my Gradle cache, I always get this error when trying to build FreeDcam 4.1final.

For some reason, this seems to fix the issue:

i think it has something todo with latest gradle and the the build tools. with updating to as 3.1.2 and gradle 4.6 i was forced to update build tools to 28.0.2 i cant reproduce the problem, so i think the above is the solution.

my .idea/libraries/Gradle__android_arch_lifecycle_runtime_1_0_3.xml

I tried building 3de686b291c5ede065b1b75581a20fe00ac9143d and I got a similar error:

> Could not resolve all artifacts for configuration ':classpath'.
   > Could not find aapt2-proto.jar (com.android.tools.build:aapt2-proto:0.3.1).

         https://jcenter.bintray.com/com/android/tools/build/aapt2-proto/0.3.1/aapt2-proto-0.3.1.jar

To fix it, I also had to change the order in buildscript:

normaly that stuff get downloaded on first project import. im a windows user, cant say much about osx or linux. you can try to unload the project and reimport it. it fix most time such problems

I don't use Android Studio, I run Gradle manually in a terminal. And that is also what F-Droid (https://github.com/KillerInk/FreeDcam/issues/8) does.

Would you accept a pull request with the small changes I mentionned above? (This solution is also mentioned here and here.)
