Unable to run Drools Android serialized-kbase example in Android N devices

I have been able to run the drools serialized-kbase example (https://github.com/kiegroup/droolsjbpm-integration/tree/6.5.0.Final/drools-examples-android/serialized-kbase) in devices with API level 21. But for all newer devices I am getting the error
dalvik.system.DexPathList is not accessible from MultiDexClassLoader
What is the solution for running drools on new phones?
I am using Android Studio Canary 9 to build the application for java 1.8 support.
My gradle depenedencies are as follows:
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:appcompat-v7:25.0.0'
compile (group: 'org.drools', name: 'drools-android', version: '6.5.0.Final') {
exclude group: 'org.slf4j' , module: 'slf4j-api'
}
compile 'org.slf4j:slf4j-api:1.7.2'
compile 'com.github.tony19:logback-android-core:1.1.1-3'
compile('com.github.tony19:logback-android-classic:1.1.1-3') {
exclude group: 'com.google.android', module: 'android'
}

Android libraries: versions conflict issue

I've the below dependence in my Android app build.gradle
compileSdkVersion 25
buildToolsVersion "25.0.2"
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:design:25.0.0'
compile 'com.android.support:appcompat-v7:25.0.0'
compile 'com.google.android.gms:play-services:10.0.1'
compile 'com.google.firebase:firebase-core:10.0.1'
compile 'com.google.firebase:firebase-messaging:10.0.1'
compile 'com.firebase:firebase-jobdispatcher-with-gcm-dep:0.6.0'
compile 'com.google.firebase:firebase-appindexing:10.0.1'
compile 'com.google.firebase:firebase-ads:10.0.1'
testCompile 'junit:junit:4.12'
compile 'com.android.support:multidex:1.0.1'
}
but getting an error about versions compatibility, as shown below, what is the one to be changed here, i could not figure it out :(

I had same problem what i did was compile the higher version of libraries ,which were creating this error,in app:gradle only.
for example in your case
compile 'com.android.support:mediarouter-v7:25.0.0'
Add this in app:gradle.
There may be more like this mediarouter libraries if it still give error add them jst like this(making them higher version).

First you need to find out where's what consists of a conflicting version of the library. The easiest way to do so is to:
Open Terminal pane in your Android Studio.
Type in: ./gradlew androidDependencies
Find the row that represents the ENCLOSING library consisting of a conflict.
Then just use exclude statement for the conflicting library, like so:
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
(the example assuming com.android.support.test.espresso:espresso-core:2.2.2 was the ENCLOSING library, and com.android.support:support-annotations being the conflict)

Authorizing google API error

I'm trying to Authorizing and using googel API for android but when I try to configure build dependencies and sync the project it give me an error like
Error:Execution failed for task ':app:prepareDebugAndroidTestDependencies'.> Dependency Error.
See console for details.
build gradle (app):
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:24.2.1'
testCompile 'junit:junit:4.12'
compile 'com.google.android.gms:play-services-auth:10.2.0'
compile 'com.google.api-client:google-api-client:1.22.0'
compile 'com.google.api-client:google-api-client-android:1.22.0'
compile 'com.google.apis:google-api-services-people:v1-rev4-1.22.0'
how can I solve this?

Not sure, but I think your google apis are conflicting
compile 'com.google.android.gms:play-services-auth:10.2.0'
and
compile 'com.google.api-client:google-api-client:1.22.0'
Might internally be using other dependencies, with different versions.
Try running: /gradlew app:dependencies to see all your dependencies

Vitamio crash on LibChecker. Added Vitamio using gradle

I add viatmio library using gradle in android studio V2.2 .
It crash at
if (!LibsChecker.checkVitamioLibs(this))
with exception like
couldn't find "libvinit.so"
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'me.neavo:vitamio:4.2.2'
testCompile 'junit:junit:4.12'
}
Need any suggestions or correction.
Thanks

Download latest version of Vitamio from Official Web site and Add this line to initiate
Vitamio.isInitialized(this);

Why does Android Studio delete dependencies listed in build.gradle?

Earlier this week Android Studio started randomly deleting dependencies from my build.gradle file whenever I create a new file.
Is there a particular order that's expected?
My dependencies section looks like this:
dependencies {
compile project(':ParallaxScroll')
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.gms:play-services:4.+'
compile 'com.android.support:support-v4:19.+'
compile 'com.android.support:support-v13:19.+'
compile 'com.android.support:appcompat-v7:19.+'
compile group: 'com.squareup.picasso', name: 'picasso', version: '2.2.0'
compile group: 'com.squareup.retrofit', name: 'retrofit', version: '1.4.1'
compile 'com.github.gabrielemariotti.cards:library:1.5.0'
compile 'com.viewpagerindicator:library:2.4.1#aar'
compile 'com.readystatesoftware.systembartint:systembartint:1.0.3'
compile 'com.crashlytics.android:crashlytics:1.+'
}
When I create a new activity in the project it ends up looking like this (this happens every time):
dependencies {
compile project(':ParallaxScroll')
compile fileTree(dir: 'libs', include: ['*.jar'])
compile group: 'com.squareup.picasso', name: 'picasso', version: '2.2.0'
compile group: 'com.squareup.retrofit', name: 'retrofit', version: '1.4.1'
compile 'com.google.android.gms:play-services:4.+'
compile 'com.android.support:support-v4:19.+'
compile 'com.android.support:support-v13:19.+'
compile 'com.android.support:appcompat-v7:19.+'
}
It took a little while to figure out what was happening.
Which of the two compile formats I'm using is correct? Is this potentially causing issues? It wasn't an issue until this week.
I can of course restore my dependencies but this doesn't explain why AS is deleting things all the time.
I'm also concerned about both support libraries being included. As far as I know I'm using only v4 stuff. Is using both bad practice?

This is a bug that will be fixed in 0.5.9. You can track it here:
https://code.google.com/p/android/issues/detail?id=60749
In the meantime, as a workaround, just create new activities by hand, or save off the contents of the build file before creating them through the wizard.
