I am making a library project for a vendor and it needs Android Volley as a dependency. I have used this Create aar file in Android Studio to create the .aar file and to include this in a test project I am using this Adding local .aar files to Gradle build using "flatDirs" is not working. The library is linked fine and there are no errors in the project compilation. But at runtime the test application crashes saying it cannot find Volley
java.lang.NoClassDefFoundError: Failed resolution of: Lcom/android/volley/toolbox/Volley;
Caused by: java.lang.ClassNotFoundException: Didn't find class "com.android.volley.toolbox.Volley" on path: DexPathList[[zip file "/data/app/in.gridsync.acttest-1/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]
Caused by: java.lang.NoClassDefFoundError: Class not found using the boot class loader; no stack available
My Gradle file for the library project is like this
apply plugin: 'com.android.library'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
minSdkVersion 14
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.mcxiaoke.volley:library:1.0.19'
}
and in the test project the gradle is this
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "in.gridsync.acttest"
minSdkVersion 14
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile project(':openapp-library')
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.0'
}
I assumed, when the .aar package was created, it'd use and include the dependency it has on Volley library. Can someone please throw some light on this?

Far as I know, you must add "@aar" for the .aar libraries. Also the jar file isn't required, it downloads that by itself.
Try this:
compile 'com.mcxiaoke.volley:library:[email protected]'
