我试图鼓励我从SQLite切换到Realm的工作。最大的反对意见是它的应用程序有多大。在Realm之后，编译发布APK从3.5MB跳到7.5MB（4MB差异）。物理设备上的安装后大小似乎有所不同，但Nexus 6P上的漫游大小约为19MB（与SQLite版本相比差异为6MB），Nexus 5上的漫游大小为16MB。无法缩小大小Realm添加到应用程序
这看起来远远大于Realm文档指示I应该期待，但似乎我能做的不多。我试过APK分裂截至https://realm.io/docs/java/latest/#how-big-is-the-realm-library记录，但是当我运行gradlew installDebug命令，我得到这些错误：
Skipping device 'Nexus 5 - 5.1.1' for 'app:release': Could not find build of variant which supports density 480 and an ABI in armeabi-v7a, armeabi
Skipping device 'Nexus 6P - 6.0.1' for 'app:release': Could not find build of variant which supports density 560 and an ABI in arm64-v8a, armeabi-v7a, armeabi
有没有办法让APK拆分工作，所以只有本地代码为给定设备的处理器是否需要，或者我还能做些什么来缩小APK的尺寸？我认识到这并不是一个巨大的，巨大的影响，但它涉及到我的上级，并且增加50％的应用程序的大小非常可观。
的build.gradle文件，在情况下，它可以帮助：

@Abdellah：那也可能有用，但我的目标是让Realm小到Realm文档所说的我可以 –
