Tentei atualizar os serviços de reprodução para 8.3. Aqui está o que eu mudei:

No arquivo raiz gradle:

dependencies {
    classpath 'com.android.tools.build:gradle:1.5.0-beta1'
    classpath 'com.google.gms:google-services:1.5.0-beta2'
}

E no arquivo gradle do aplicativo:

compile 'com.google.android.gms:play-services-maps:8.3.0'
compile 'com.google.android.gms:play-services-location:8.3.0'
compile 'com.google.android.gms:play-services-base:8.3.0'
compile 'com.google.android.gms:play-services-gcm:8.3.0'
compile 'com.google.android.gms:play-services-analytics:8.3.0'
compile 'com.google.android.gms:play-services-appinvite:8.3.0'
compile 'com.google.android.gms:play-services-ads:8.3.0'
compile 'com.google.android.gms:play-services-appindexing:8.3.0'

Está funcionando bem, mas falha ao iniciar com o seguinte rastreamento de pilha:

Temos o programa ativado, e geralmente temos métodos de 50 / 55k em nosso apk integrado. Mas com essa configuração, temos 26k.

Nossa configuração original era

classpath 'com.android.tools.build:gradle:1.3.0'
classpath 'com.google.gms:google-services:1.4.0-beta3'

Com todas as dependências do play services com a versão 8.1.0

Alguma idéia do que está acontecendo lá?
