Coverage report says zero coverage on android with gradle - java

I've been unable to get code coverage to work on any of my android projects.
To simplify things I created a new project (selected empty activity).
Added a new utility class to the the project in src/main/java.
I then created a unit test for it in src/androidTest/java.
Updated the gradle file to enable coverage.
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.example.michaelkrussel.coverageapp"
minSdkVersion 15
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
jacoco {
version "0.7.1.201405082137"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
testCoverageEnabled true
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
}
I ran the tests then using ./gradlew createDebugCoverageReport. The unit test shows that the test I created passed, but the coverage report reports zero coverage.
I assume I'm either missing something in the gradle file or not running the correct gradle task, but I cannot figure out what.


I'm using this configuration in my project and work fine!
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.1"
defaultConfig {
applicationId "br.com.acs.app"
minSdkVersion 18
targetSdkVersion 21
versionCode 1
versionName "1.0"
testApplicationId "br.com.acs.app.test"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
testCoverageEnabled true
}
}
packagingOptions {
exclude 'LICENSE.txt'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
androidTestCompile 'junit:junit:4.11'
androidTestCompile('com.android.support.test:testing-support-lib:0.1') {
exclude group: 'junit'
}

the app compila when i delete this line:

but the app after moment automatic close

Try
apply plugin: 'com.android.application'

}
}
}

compile 'com.loopj.android:android-async-http:1.4.9'
compile 'com.android.support:multidex:1.0.2'
}
Beside this, please review your dependency versions. They are not the latest versions and you might want to update them. Take care of the buildToolsVersion as well.

Java.exe error while building project in Android Studio

After creating a new project when I try to run the app it shows build failed error.
I searched for it on the internet, they say that it may be due to duplicate libraries of gradle or duplicate dependencies in gradle file, but it wasn't so In my case.
Here is my build.gradle file :
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.example.naveenjain.ayusch"
minSdkVersion 14
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
}

Try to delete this line:
compile fileTree(dir: 'libs', include: ['*.jar'])
Or you could set multiDexEnabled true:
defaultConfig {
// Enabling multidex support.
multiDexEnabled true
}
and try again. Hope it helps.

cannot see Theme.Material or Android L's things

when i create values-v21 for android L' styles but when i cntrl+space for search there isn't any android L library.I checked android sdk manager,everything updated. and i'm using these library in build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "......."
minSdkVersion 13
targetSdkVersion 20

}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

compile 'com.github.mrengineer13:snackbar:0.4.0'
}
android {
packagingOptions {
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}
}

you do not reference android L anywhere
your gradle should have these in it
compileSdkVersion 'android-L'
minSdkVersion 'L'
targetSdkVersion 'L'
