Debugging test case in Android Studio

How do you debug JUnit test case in Android studio? I placed a breakpoint and used "Debug Test case" but it just runs the code and the breakpoint is ignored.
Update:
This is content of my build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.****.mancala"
minSdkVersion 18
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
debuggable true
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
}

Depending on the Run/Debug Configuration used, the same code with the same breakpoint will stop or not.
For a configuration with Test kind: All in package, the execution
will not stop at breakpoint
For a configuration with Test kind: Class or Test kind: Method, the execution will stop at breakpoint
For a configuration with Test kind: All in directory with Directory: [myProjectPath]/app/src/test, the execution will stop at breakpoint

Make sure that in your build.gradle file (one with all your dependencies) that you have debuggable true within the debug build type.
Also just for good measure make sure its a valid breakpoint (not an empty line etc.)

how to generate app-debug

when I pressed run button I checked apk floder where app-debug-unaligned.apk generated but app-debug.apk not refreshed. I don't know what I did that this happened. check the date in picture
EDIT: maybe people think I am lying but it's not true. maybe problem is in build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.0"
defaultConfig {
applicationId "ir.parsdroid.instagrameducation"
minSdkVersion 8
targetSdkVersion 23
versionCode 11
versionName "1.5.3"
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
debug {
minifyEnabled true
proguardFile 'proguard-android-optimize.txt'
zipAlignEnabled false
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.android.support:support-v4:23.0.0'
compile files('src/main/libs/adad-2.9.jar')
}

In android studio, APK gets generated when we rebuild an application or run an application.
To get debug apk :
Rebuild your project or run your project
check your_app_location\app\build\outputs\apk
Edited :
Here in your gradle file you have used 'zipAlignEnabled' :
debug {
minifyEnabled true
proguardFile 'proguard-android-optimize.txt'
zipAlignEnabled false
}
Problem is because of it. So please check how to use 'zipAlignEnabled' and try again.!!
Hope it will help.

Agree with Mamata Gelanee. You can simply remove app-debug.apk file from folder and clean the project and release new build again then check.

UNEXPECTED TOP-LEVEL EXCEPTION : DexIndexOverflowException while running the app on Android studio

I am using google play services version 7.5.0 and getting below mentioned error while running a project.
My project contains 2 modules.
Here are the build.gradle file of each modules.
Module 1:
apply plugin: 'com.android.library'
android {
compileSdkVersion 22
buildToolsVersion "23.0.0 rc3"
defaultConfig {
minSdkVersion 9
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:support-v4:22.2.0'
compile 'com.google.android.gms:play-services:7.5.0'
}
Module 2:
apply plugin: 'com.android.library'
android {
compileSdkVersion 22
buildToolsVersion "23.0.0 rc3"
defaultConfig {
minSdkVersion 9
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile project(':module1')
}
And here is build.gradle file of app
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "23.0.0 rc3"
defaultConfig {
applicationId "com.vserv.offerwall"
minSdkVersion 9

}
dexOptions {
jumboMode true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile project(':module2')
}
repositories {
flatDir {
dirs 'libs'
}
}
When I am building the app, it get build successfully. But when I am trying to run the app, I am getting below mentioned error.
UNEXPECTED TOP-LEVEL EXCEPTION:

I have done some Google and found below mentioned link.
Unable to execute dex: method ID not in [0, 0xffff]: 65536
I have tried this and edited the app gradle file by adding multiDexEnabled true into defaultConfig and compile 'com.android.support:multidex:1.0.0' in dependencies.
After that the above mentioned error is resolved and then I got another error while running the app.
:app:shrinkDebugMultiDexComponents FAILED
Error:Execution failed for task ':app:shrinkDebugMultiDexComponents'.
java.io.IOException: Can't read [D:\StudioWorkspace\SampleSDKDemoProject\app\build\intermediates\multi-dex\debug\allclasses.jar] (Can't process class [org/fmod/FMODAudioDevice.class] (256))
Kindly help me to solve this.
Thanks in advance.

Instead of importing ALL modules from google services
compile 'com.google.android.gms:play-services:7.5.0'
Import only the modules you need. Check this page.
Note: If the number of method references in your app exceeds the 65K
limit, your app may fail to compile. You may be able to mitigate this
problem when compiling your app by specifying only the specific Google
Play services APIs your app uses, instead of all of them.

Multiple dependencies are trying to import “UNEXPECTED TOP-LEVEL EXCEPTION:”

I have two libraries on my proyect.

https://github.com/navasmdc/MaterialDesignLibrary
It compiles, but when I run the program it reports an error.

I KNOW THE PROBLEM, BUT I CAN'T SOLVE
Problem
Multiple dependencies are trying to import nineoldandroids exactly "nineoldandroids"
app build.gradle
apply plugin: 'com.android.application'
android {

buildToolsVersion "21.1.2"
defaultConfig {

compile 'com.android.support:appcompat-v7:21.0.3'
//seconds library
compile project(':materialDesign')
//first library
compile project(':EditText')
}
first library build.gradle

}
}
}
dependencies {
compile 'com.android.support:support-annotations:21.0.3'
compile 'com.nineoldandroids:library:2.4.0'
compile 'com.android.support:appcompat-v7:21.0.3'
}
seconds library build.gradle
apply plugin: 'com.android.library'
android {
compileSdkVersion 8
buildToolsVersion "19.1.0"
defaultConfig {
minSdkVersion 8
targetSdkVersion 8
}
buildTypes {
release {

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:support-v4:18.+'
compile files('libs/nineoldandroids-2.4.0.jar')
}
I have tried:
1. Put on "app" build.gradle:
compile project(':EditText') {
exclude group: 'com.nineoldandroids', module: 'library:2.4.0'
}
NOT WORKS, IT'S REPORTS AN ERROR
Error:(31, 0) Gradle DSL method not found: 'exclude()'
Possible causes:<ul><li>The project 'Proyecto' may be using a version of Gradle that does not contain the method.
Gradle settings</li><li>The build file may be missing a Gradle plugin.
Apply Gradle plugin</li>
2. Remove "nineoldandroids" from seconds library, NOT WORKS
Any suggestions?

I don't know how to import using their respective artifacts
It is in the documentation for each library.
The MaterialEditText "Download" section cites:
compile 'com.rengwuxian.materialedittext:library:1.8.2'
The "How to Use" section of MaterialDesignLibrary cites:
repositories {
jcenter()
}
dependencies {
compile 'com.github.navasmdc:MaterialDesign:1.+#aar'
}
Then, Gradle will (hopefully) be able to detect that both of these dependencies themselves depend upon nineoldandroids and resolve the conflict. I say "hopefully" because whichever library the "seconds library build.gradle" comes from uses a local copy of nineoldandroids, which is not a good idea. Neither GitHub repo seems to have that particular build.gradle file, though, so you may be OK.

useOldManifestMerger causes build error

I'm trying to use this new feature available in the version 0.10.0 of the Gradle Plugin for Android. But I keep getting this error message:
FAILURE: Build failed with an exception.
What went wrong: Execution failed for task ':xxxxxx:processDebugManifest'.
Manifest merger failed : uses-sdk:minSdkVersion 1 cannot be smaller than version 7 declared in library
com.android.support:appcompat-v7:19.1.0
Here's my build.gradle
apply plugin: 'android'
android {
compileSdkVersion 19
buildToolsVersion '19.0.3'
useOldManifestMerger false
defaultConfig {
minSdkVersion 9
targetSdkVersion 19
}
buildTypes {
release {
runProguard true
proguardFile 'proguard-zap.cfg'
signingConfig signingConfigs.release
debuggable false
zipAlign true
}
debug {
packageNameSuffix ".debug"
debuggable true
runProguard false
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
dependencies {
compile fileTree(dir: 'libs')
compile 'com.android.support:appcompat-v7:+'
compile 'com.google.android.gms:play-services:+'
compile 'com.google.code.gson:gson:+'
androidTestCompile files('libs/espresso-1.1-bundled.jar')
}
How do I solve this?

I had the same error.
As a temporary fix, you can add this in your manifest file:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19"
tools:replace="minSdkVersion, targetSdkVersion"/>
The tools namespace is declared as follow: xmlns:tools="http://schemas.android.com/tools". The downside of this fix is that you have to keep build.gradle and the manifest in sync with the value in minSdkVersion and targetSdkVersion. Hopefully it will be fixed in 0.10.1.

Looks like it was fixed in 0.10.4
