Solution 1:

Edit:

Please check you having this two libraries common :

compile'com.yalantis:ucrop:2.2.0'compile'com.yalantis:ucrop:2.2.0-native'

remove one of them and check which one is needed for you.

Check this answer for multidex issue.that one helped me to fix that issue.

It seems your logcat clearly shows annotations identifier DexException: Multiple dex files define Lorg/intellij/lang/annotations/Identifier. You should remove this line support -annotations:

 androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

Moreover, If you are using google play services bundle like this : compile 'com.google.android.gms:play-services:8.1.0

change into below gms separately for all libraries

compile 'com.google.android.gms:play-services-location:8.1.0'
 compile 'com.google.android.gms:play-services-base:8.1.0'
 compile 'com.google.android.gms:play-services-analytics:8.1.0'
 compile 'com.google.android.gms:play-services-maps:8.1.0'

 compile "com.google.android.gms:play-services-gcm:8.1.0'    //

for gcm push notification

Solution 2:

Try enabling multidex . inside app level build.gradle write these lines

   android {
...
   defaultConfig {
       ...
       // Enabling multidex support.
       multiDexEnabled true
       ...
   }

...
}
dependencies {
...
   compile 'com.android.support:multidex:1.0.1'
...
}
