please help. I am having a really horrible time with setting up my testing for android studio.
I have downloaded the calculator example to practice cumcumber code testing from the cucumber github. https://github.com/cucumber/cucumber-jvm/tree/master/android (some of these brands btw are very strangley named)
I tried to use it with Android studio. The program runs perfect (yay!). The test however does not. I have a really horrible message that just haunts me every time i run it.
*To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environment.html
Error:Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.
Error:1 error; aborting

Its the target compatibility and source compatibility i am having trouble with (have not got to the rest yet)
Here's the gradle build: as you can see i have changed the compatibility to 1.7

Now ive tried this:
Error when using a jar in my project
and this: Is it possible to use Java 8 for Android development?
and this: Gradle sourceCompatibility has no effect to subprojects
in both the project gradle and the app gradle. But i'm am thinking as its only coming with testing...these will not help and its something to do with the dependencies and for that i am pretty stuck. Can anyone help! thanks in advance
