No signature of method: .android() is applicable for argument types. Exception in build.gradle (app)

by

Best way to deal with this is going in the android { … } block and start commenting out different methods/blocks until the configuration moves past the .android() error and you’ll know which block is causing it. In my case it was a deprecated method in the buildTypes { … } block.

Increase heap memory for ‘gradle test’

The accepted answer above works but the Gradle documentation here suggests you use maxParallelForks = Runtime.runtime.availableProcessors().intdiv(2) ?: 1 I tried both and after testing both on a 2.3 GHz Intel Core i7 Mac Book Pro with 16GB RAM (4 cores with hyperthreading) test { maxParallelForks = Runtime.runtime.availableProcessors() } and test { maxParallelForks = Runtime.runtime.availableProcessors().intdiv(2) ?: … Read more

Failure on build with Gradle on command line with an android studio project : Xlint error

by

It’s a nice warning, not an error. To see the complete lint report you can add these lines to build.gradle: allprojects { tasks.withType(JavaCompile) { options.compilerArgs << “-Xlint:deprecation” } } If you really want to get rid of those warnings: Don’t use deprecated API Use @SuppressWarnings(“deprecation”)

However you are going to need to add evaluationDependsOn(‘:project1’) evaluationDependsOn(‘:project2’) so that gradle will evaluate project1 and project2 before module. In all the projects that contain code you will need to have an empty build.gradle file. This will also allow you to customize a project … Read more
