我試圖鼓勵我從SQLite切換到Realm的工作。最大的反對意見是它的應用程序有多大。在Realm之後，編譯發佈APK從3.5MB跳到7.5MB（4MB差異）。物理設備上的安裝後大小似乎有所不同，但Nexus 6P上的漫遊大小約爲19MB（與SQLite版本相比差異爲6MB），Nexus 5上的漫遊大小爲16MB。無法縮小大小Realm添加到應用程序
這看起來遠遠大於Realm文檔指示I應該期待，但似乎我能做的不多。我試過APK分裂截至https://realm.io/docs/java/latest/#how-big-is-the-realm-library記錄，但是當我運行gradlew installDebug命令，我得到這些錯誤：
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
有沒有辦法讓APK拆分工作，所以只有本地代碼爲給定設備的處理器是否需要，或者我還能做些什麼來縮小APK的尺寸？我認識到這並不是一個巨大的，巨大的影響，但它涉及到我的上級，並且增加50％的應用程序的大小非常可觀。
的build.gradle文件，在情況下，它可以幫助：

@Abdellah：那也可能有用，但我的目標是讓Realm小到Realm文檔所說的我可以 –
