發佈版本：transformClassesAndResourcesWithProguardForRelease失敗

Question

簽署了產生APK：

Note: there were 8 unresolved dynamic references to classes or interfaces. 
Note: there were 4 accesses to class members by means of introspection. 
Warning: there were 5 unresolved references to classes or interfaces. 
Warning: there were 1 unresolved references to program class members. 

transformClassesAndResourcesWithProguardForRelease FAILED 

Full Gradle log is here。

My app build.gradle is here。

UPD。 Stacktrace is here。

如果我使用-ignorewarnings選項，那麼該應用會在某些版本的Android上崩潰。

大概在進入房間後，我停止生成簽名的APK。 另外，我不得不將com.google.firebase，com.google.android.gms：play-services從11.0.4降級到11.0.2。

兩個簡單的問題（對於那些知道的人）。

日誌說：

Try: Run with --stacktrace option to get the stack trace. 
Run with --info or --debug option to get more log output. 

Q1。在Android Studio中，我可以指定「--stacktrace」，「--info或--debug」選項？第二季度銷售價格下降，第二季度銷售價格下降，第三季度銷售價格下降。如何（我閱讀日誌）我必須找出哪些課程缺失？我應該在哪裏看？要找什麼？

Answer 1

Q1：在從項目的根命令行：./gradlew build --stacktrace

Q2：你應該修改警告：

Warning: android.arch.persistence.room.paging.LimitOffsetDataSource: can't find superclass or interface android.arch.util.paging.CountedDataSource 
Warning: android.arch.persistence.room.paging.LimitOffsetDataSource: can't find referenced class android.arch.util.paging.CountedDataSource 
Warning: android.arch.persistence.room.paging.LimitOffsetDataSource: can't find referenced class android.arch.util.paging.CountedDataSource 
Warning: android.arch.persistence.room.paging.LimitOffsetDataSource: can't find referenced class android.arch.util.paging.CountedDataSource 
Warning: android.arch.persistence.room.paging.LimitOffsetDataSource: can't find referenced class android.arch.util.paging.CountedDataSource 
Warning: android.arch.persistence.room.paging.LimitOffsetDataSource$1: can't find referenced method 'void invalidate()' in program class android.arch.persistence.room.paging.LimitOffsetDataSource 

而且你可以嘗試添加到您的ProGuard文件：

-dontwarn android.arch.util.paging.CountedDataSource 
-dontwarn android.arch.persistence.room.paging.LimitOffsetDataSource 

Answer 2

你可以在這裏看到什麼類缺失

Warning: android.arch.persistence.room.paging.LimitOffsetDataSource: can't find superclass or interface android.arch.util.paging.CountedDataSource 
Warning: android.arch.persistence.room.paging.LimitOffsetDataSource: can't find referenced class android.arch.util.paging.CountedDataSource 
Warning: android.arch.persistence.room.paging.LimitOffsetDataSource: can't find referenced class android.arch.util.paging.CountedDataSource 
Warning: android.arch.persistence.room.paging.LimitOffsetDataSource: can't find referenced class android.arch.util.paging.CountedDataSource 
Warning: android.arch.persistence.room.paging.LimitOffsetDataSource: can't find referenced class android.arch.util.paging.CountedDataSource 
Warning: android.arch.persistence.room.paging.LimitOffsetDataSource$1: can't find referenced method 'void invalidate()' in program class android.arch.persistence.room.paging.LimitOffsetDataSource 

看看如何實現proguard的來處理這個類，你可以嘗試添加到您的proguard-rules.pro文件：

-dontwarn android.arch.** 

，或者您可以從您的構建禁用的ProGuard（ here）
