Firebase数据库遇到OutOfMemoryError

Question

我的应用程序需要100％将数据同步到Firebase数据库，即使它处于脱机状态也必须正常工作，因此我启用了离线功能，如official document所述。

问题是在使用应用程序一段时间后应用程序崩溃了，甚至重新安装了应用程序

我按照堆栈跟踪中的说明浏览了文档，我的应用程序上没有读取只写入Firebase数据库

Fatal Exception: java.lang.RuntimeException: Firebase Database encountered an OutOfMemoryError. You may need to reduce the amount of data you are syncing to the client (e.g. by using queries or syncing a deeper path). See https://firebase.google.com/docs/database/ios/structure-data#best_practices_for_data_structure and https://firebase.google.com/docs/database/android/retrieve-data#filtering_data
