I hava setted up a App project with retrolambda for JAVA 8 compatibility and a module dependency to a own android library, because I used this part in a second App too. The problem is that every time I build my Project with gradle there is no error and the build success, but when I want to install the App on my Device, gradle fails in
:app:compileDebugJavaWithJavac with package R does not exist
Here is my gradle setup:
build.gradle (Project: "Projectname")
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.2'
classpath 'me.tatarka:gradle-retrolambda:3.2.5'
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
build.gradle (Module: app)
apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'
android {

}
}
}

testCompile 'junit:junit:4.12'
compile 'com.android.support:design:24.0.0'
compile 'org.florescu.android.rangeseekbar:rangeseekbar-library:0.3.0'
compile project(path: ':myownmodule')
}
build.gradle (Module: myownmodule)
apply plugin: 'com.android.library'

android {

}

}
buildTypes {

This is the output from gradle console:

I'm wondering about this, because my second app with the same setup can be installed without any problem. Why gradle crashs in this app? In my java classes there is while programming no problem and the import to the android R class exists, but while build for installing gradle removed this import and all R's will be red till a few seconds. Android Studio auto import the right R
import my.package.app.R;
and after the import the R's are not red anymore.
I have tested a gradle clean and rebuild several times (as suggested in other questions) without fixing the problem...
Thanks for helping :D
