I am able to run my app when i change to debug mode but it fails when i switch to release mode.

Error:

Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'. java.io.IOException: Please correct the above warnings first.

-

build.gradle

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
useLibrary 'org.apache.http.legacy'

defaultConfig {
    applicationId "com.application.app"
    minSdkVersion 14
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"

    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
    }
}

dexOptions {
    incremental true

}
}

}

EDIT: As you can see the multidex is enabled in my build.gradle file.

EDIT 2:

App.java

public class App extends MultiDexApplication {

public static GoogleAnalytics analytics;
public static Tracker tracker;

@Override
public void onCreate() {
    super.onCreate();
    MultiDex.install(this);

    analytics = GoogleAnalytics.getInstance(this);
    analytics.setLocalDispatchPeriod(1800);
    tracker = analytics.newTracker("myAnalyticsId");
    tracker.enableExceptionReporting(true);
    tracker.enableAdvertisingIdCollection(true);
}

}

Manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.application.app" android:installLocation="preferExternal">

@DevrimTuncer As you can see the multidex is enabled in my build.gradle file. — John Edward, Jun 17 '16 at 10:40
What about your manifest and application class? Please check the answer at the link I've shared. — Devrim, Jun 17 '16 at 10:42
remove this line, it is already included in play-services.-> compile 'com.google.android.gms:play-services-analytics:9.0.2' — Vivek Sinha, Jun 17 '16 at 10:54
If it is saying **Please correct the above warnings first.** What are that warnings ?? — Janki Gadhiya, Jun 17 '16 at 11:24
Since, you have set minifyEnabled to true for release build, you need to configure Proguard for the project. Please see the Proguard related documentation for various libraries you have used. — Chebyr, Jun 17 '16 at 11:31

the problem is in using com.google.android.gms:play-services:9.0.2 instead of using all google play services try to to use just what you need

and yes you are using

compile 'com.google.android.gms:play-services-analytics:9.0.2'

and then

compile 'com.google.android.gms:play-services:9.0.2'

the play-services-analytics:9.0.2 is included in play-services:9.0.2

just remove

com.google.android.gms:play-services:9.0.2
