Getting MultiDex error while adding dependency for gcm and onesignal push notification

Problem: When I add the below dependencies in build.gradle, I am getting a multiDex error. I know this happens if I have unnecessary dependency but I am not able to sort it out. I am doing this for one single push notification in my app.
I added following dependencies to my build.gradle file:
compile 'com.google.android.gms:play-services:8.1.0'
compile 'com.google.android.gms:play-services-ads:8.1.0'
compile 'com.google.android.gms:play-services-identity:8.1.0'
compile 'com.google.android.gms:play-services-gcm:8.1.0'
compile 'com.onesignal:OneSignal:2.+#aar'
compile 'com.google.android.gms:play-services-analytics:8.1.0'
compile 'com.google.android.gms:play-services-location:8.1.0'
Before this my app was working fine. All of tthe dependecies in my gradle file are listed below (including the above dependencies)
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile files('libs/android-support-v4.jar')
compile files('libs/Parse-1.3.0.jar')
compile files('libs/signpost-commonshttp4-1.2.1.2.jar')
compile files('libs/signpost-core-1.2.1.2.jar')
compile files('libs/signpost-jetty6-1.2.1.2.jar')
testCompile 'junit:junit:4.12'
compile files('libs/volley.jar')
compile 'com.google.android.gms:play-services:8.1.0'
compile 'com.google.android.gms:play-services-ads:8.1.0'
compile 'com.google.android.gms:play-services-identity:8.1.0'
compile 'com.google.android.gms:play-services-gcm:8.1.0'
compile 'com.onesignal:OneSignal:2.+#aar'
compile 'com.google.android.gms:play-services-analytics:8.1.0'
compile 'com.google.android.gms:play-services-location:8.1.0'
}
Any help on how to fix this?

If your intention is just to add Gcm. you dont need those many dependencies. Especially google play services full version.
compile 'com.google.android.gms:play-services:8.1.0'
Its always good to add smaller dependencies which fits your usecase such as
compile 'com.google.android.gms:play-services-gcm:8.1.0'
If you still are still exceeding 65k limit and need multidex, you must enable in your module gradle file.
multiDexEnabled true
in your module grandle file in defaultConfig.
Along with this, its better enable proguard to keep following attributes as well to make sure you dont bloat up the apk size
minifyEnabled true
shrinkResources true
Note that enabling proguard has its own problems which you will have deal with by carefully reviewing proguard-rules.pro

if you can't solve your application's dependencies.
multi dex application supporting can be solution for that.

More than 8 hours and Android Studio is still not finished building my app (w/ Proguard-minify on)

I expected the build to take a significant amount of time but not as long as it is now. It's already past 8 hrs (9PM - 6AM) after I began but it's still not finished.
Details:
My PC is relatively powerful (built for gaming)
I extensively use external libraries, here they are:
Code:
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'org.adw.library:discrete-seekbar:1.0.0'
compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.android.support:design:23.2.0'
compile 'com.android.support:cardview-v7:23.2.0'
compile 'com.android.support:recyclerview-v7:23.2.0'
compile 'com.android.support:support-v13:23.2.0'
compile 'com.android.support:gridlayout-v7:23.2.0'
compile 'com.android.support:support-v4:23.2.0'
compile 'com.google.android.gms:play-services-ads:8.4.0'
compile 'com.flipboard:bottomsheet-core:1.5.0'
compile 'com.flipboard:bottomsheet-commons:1.5.0'
compile 'com.guerwan:transitionbackport:1.1'
compile 'com.nhaarman.listviewanimations:lib-manipulation:3.1.0#aar'
compile 'com.nineoldandroids:library:2.4.0'
compile 'com.ogaclejapan.smarttablayout:library:1.6.0#aar'
compile 'com.github.traex.rippleeffect:library:1.3'
compile 'asia.ivity.android:drag-sort-listview:1.0'
compile 'org.adw.library:discrete-seekbar:1.0.0'
compile 'com.liulishuo.filedownloader:library:0.1.9'
compile 'org.apache.commons:commons-lang3:3.4'
compile 'com.github.castorflex.smoothprogressbar:library:1.0.1-SNAPSHOT#aar'
compile 'org.jetbrains:annotations-java5:15.0'
QUESTION:
Why is that the case? Is there anyway to minimize it? Or is it even normal not a bug? Thanks.

I've had this happen a few times in the past, especially when on a flaky internet connection. Here's what I would try:
Force close Android Studio and re-launch.
Enabled Gradle Offline Work (assuming you have cached versions of your dependencies) by going to File->Settings->Build,Execution,Deployment->Build Tools->Gradle and then check "Offline Work"
Generate your .apk
If you still are having problems building after that, I would try File->Invalidate Caches and Restart. Do you also have this issue when generating .apks with with ProGuard disabled?

Android Studio Google endpoints causing UNEXPECTED_TOP_LEVEL_EXCEPTION

I searched for ages to determine why my google endpoints module was causing a UNEXPECTED_.._EXCEPTION when I tried to run the App on a emulator.
Research indicated that a library is being called more than once. But I could find no clear error with regard to this:
My app build.gradle:
compile project(path: ':kk_endpoint', configuration: 'android-endpoints')
compile'com.android.support:appcompat-v7:22.2.0'
compile 'com.google.android.gms:play-services:7.5.0'
compile 'com.android.support:design:22.2.0'
compile 'com.android.support:recyclerview-v7:22.2.0'
compile 'com.android.support:cardview-v7:22.2.0'
compile 'de.hdodenhof:circleimageview:1.3.0'
compile 'com.squareup.picasso:picasso:2.3.2'
And my Google endpoint module build.gradle:
appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.19'
compile 'com.google.appengine:appengine-endpoints:1.9.19'
compile 'com.google.appengine:appengine-endpoints-deps:1.9.19'
compile 'javax.servlet:servlet-api:2.5'
compile 'com.googlecode.objectify:objectify:5.1.1'
compile 'com.ganyo:gcm-server:1.0.2'
Clearly nothing is being called twice on face level. What could be the cause of this problem?

After hours of research I found that the problem was coming from the guava lib, and all I needed to do was exclude that lib:
compile (project(path: ':kk_endpoint', configuration: 'android-endpoints')) {
exclude(module: 'guava-jdk5')
}
Please note brackets need to be exactly as above or won't work.
compile project(path: ':kk_endpoint', configuration: 'android-endpoints'){
exclude(module: 'guava-jdk5')}
Doesn't work.
I hope this helps someone save hours

Braintree Excluding Library from Gradle

I have used following dependency in my Android Studio gradle.
dependencies {
compile project(':facebookSDK')
compile project(':wheel')
compile project(':viewPagerLibrary')
compile 'com.google.code.gson:gson:2.1'
compile 'com.google.android.gms:play-services:+'
compile 'com.android.support:appcompat-v7:20.0.0'
compile 'io.card:android-sdk:5.0.0'
compile files('libs/acra-4.5.0.jar')
compile files('libs/analytics-3.4.0.jar')
compile files('libs/androidasync-1.3.8.jar')
compile files('libs/crashlytics.jar')
compile files('libs/CWAC-Adapter.jar')
compile files('libs/eventbus-2.2.0.jar')
compile files('libs/fastjson-1.1.6.jar')
compile files('libs/gradle-wrapper.jar')
compile files('libs/ion-1.3.8.jar')
compile files('libs/localytics.jar')
compile files('libs/nineoldandroids.jar')
compile files('libs/parse-1.3.0.jar')
compile files('libs/socialauth-4.4.jar')
compile files('libs/universal-image-loader-1.9.0.jar')
}
Now I need to implement Braintree Gradle dependency
compile 'com.braintreepayments.api:braintree:1.+'
But sometimes it show me some other error sometime its shows me java.exe finished with non-zero exit value 3.
I want to use this braintree dependency for payment options please help me out how can i use it without error with the current dependency.
Thanks a lot for solving my problem in advance.

The Braintree Android library depends on GSON version 2.2.4 or higher.. It looks like you're currently depending on version 2.1.0. Upgrading your dependency to 2.2.+ should satisfy Braintree's and allow installation.
If you do run into further problems, Braintree's support can help, via email at support#braintreepayments.com or phone at 877.434.2894.

Facebook SDK v4.0.1 Failing to compile with gradle

I am having trouble using Gradle to build Facebook SDK 4.0.1 in Android Studio 1.2 beta. There is no compile error, but the compiled library is not in my External Libraries. Previously, I successfully had:
compile 'com.facebook.android:facebook-android-sdk:3.22.0'
However,
compile 'com.facebook.android:facebook-android-sdk:4.0.1'
doesn't appear to do anything. From searching, it looks like this version is available on maven. Here is my complete dependency list:
dependencies {
compile 'com.google.code.gson:gson:2.3.1'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.crashlytics.android:crashlytics:1.+'
compile 'com.parse.bolts:bolts-android:1.2.0'
compile 'com.mixpanel.android:mixpanel-android:4.5.3#aar'
compile 'net.hockeyapp.android:HockeySDK:3.5.0'
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.gms:play-services:6.5.87'
//compile 'com.google.android.gms:play-services:7.0.0'
compile 'com.android.support:appcompat-v7:22.0.0'
compile project(':libraries:downloader_library')
compile project(':libraries:zip_file')
compile 'com.facebook.android:facebook-android-sdk:4.0.1'
testCompile 'junit:junit:4.12'
}
I also have had some difficulties with Google Play Services 7.0.0, hence the comment.
Is there something I am doing wrong, such as a missing dependency or an incorrect assumption?

Solved
It turns out you can't have comments in your dependencies, so removing
//compile 'com.google.android.gms:play-services:7.0.0'
Fixed the issue.
