我遇到了同样的问题并在此处阅读了解决此问题的方法，并且 禁用minifyEnabled ，生成已签名的APK。

buildTypes {
    release {
        minifyEnabled false
        shrinkResources true
        proguardFiles 'proguard-project.txt'
    }

在将buildTool更新为23.0之前，我从未遇到过这个问题。

此外，对于这个较新的版本，您需要将其添加到Progaurd.txt file。

-keep public class com.google.android.gms.* { public *; }
-dontwarn com.google.android.gms.**

希望这也有助于解决您的问题。
