Crashlytics在一些崩溃上缺少符号

Question

在我的Android应用中，有时候，一些崩溃会丢失符号。大多数崩溃都显示出完整的符号化的callstack。

示例：

# Platform: android
# Application: World Soccer Challenge


#0. Crashed: Thread

13 (Missing)                      0xde1282be (Missing)
14 (Missing)                      0xde08ef21 (Missing)

我该怎么办？ 我正在使用com.crashlytics.sdk.android:crashlytics:2.9.2
