Unity didn't add some *.aar files to the project. the follow steps are my method to resolve it.
Export Google Android project.
Open Android Studio.
select Import project(Eclipse ADT, Gradle, ect).
select the project you export and open it and clicked Next and Finsh.
Then you can find there is not .aar files in “libs” folder. So you should copy all .aar files to the libs.
Add some code to the build.gradle setting files.
just like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.Gamation.PollQuest"
minSdkVersion 9
targetSdkVersion 23
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
repositories {
flatDir {
dirs 'libs'
}
}
}
dependencies {
compile files('libs/unity-classes.jar')
compile(name:'common', ext:'aar')
compile(name:'GoogleAIDL', ext:'aar')
compile(name:'GooglePlay', ext:'aar')
}
if you didn't resolve you problem. you can send email to me. my email: bazhicc@163.com
Hi, thanks for your reply. There are several unclear points with your answers:
1 Done
2 Done
3 Done
4 Done
5 You are saying that there are no .aar files in "libs" folder but I have all these .aar files in libs folder
6 I have no build.gradle file as this is not a gradle project.
So the problem persists.
