Ben @ bishop87 en geçici çözüm from issue on github project basitleştirilmiş sürümünü kullanın. Ayrıca, daha fazla OOM güvenli hale getiren küme bitmapleri için önbelleğe alma ekledi.
bunu kullanabilir veya kendi için bu kodu taşımak daha Küme oluşturucusunu yoksa:

PS Ayrıca, istediğiniz pin rengiyle R.color.simple_green'u değiştirmeniz gerekir.
P.P.S. Unutmayın ki, bu yaklaşımın ihmal edilebilir bir performans etkisi vardır. Dolayısıyla, Google Play'in bu sorunu bir sonraki Play Hizmetleri uygulama sürümünde çözmesi halinde, bu çözümü Play Hizmetleri 9.0.83 ve diğerlerine yönelik farklı yaklaşımlarla güncellemek daha iyi olacaktır.
