How to define common android properties for all modules using gradle

Question

I create a simple project in AndroidStudio with a few modules. Each module\'s gradle script contains the following code:

android {
    compileSdkVersion 18
          


        

Answer 1

Hmm interesting that I did not find solution that works as I expet it should in Android Studio. But only this solution I present here works so there is no warning in Android Studio editor and works.

define in root build.gradle as everybody do:

buildscript {
    ext {
        projectAppCompatVersion = 'com.android.support:appcompat-v7:23.3.0'
        projectSupportVersion = 'com.android.support:support-v4:23.3.0'
        projectCompileSdkVersion = 23
        projectMinSdkVersion = 22      // 15 android 4.0.3 for release
        projectTargetSdkVersion = 23   //23 requires permission requests , 22 for release
        projectBuildToolsVersion = "24.0.0rc2"
    }
 }

and to access without warnings:

compileSdkVersion project.properties.projectCompileSdkVersion
buildToolsVersion project.properties.projectBuildToolsVersion

but code completion and variables resolution is not working as I would expect for android studio.
