Firebase SDK在接收广播意图时崩溃

Question

在最近的更新中,我们开始看到来自Firebase的2次崩溃.这些崩溃都不是可重现的,并且它们很少发生,但经常足以引起我们的关注.第一个出现在Android 7上的99%(Android 5上为1%):

Fatal Exception: java.lang.RuntimeException: Error receiving broadcast Intent { act=android.net.conn.CONNECTIVITY_CHANGE flg=0x4000010 (has extras) } in com.google.firebase.iid.f@96947cd

而这一款完全来自Android 8:

Fatal Exception: java.lang.RuntimeException: Error receiving broadcast Intent { act=android.net.conn.CONNECTIVITY_CHANGE flg=0x4000010 (has extras) } in com.google.firebase.iid.f@8746d6a

不幸的是,Firebase SDK被混淆了,所以我看不到崩溃的完整上下文,但抛出的异常是试图执行该isConnected方法的NetworkInfo对象上的NPE .

这些是我们在此构建中使用的firebase库:

api "com.google.firebase:firebase-config:11.6.2"
api "com.firebase:firebase-jobdispatcher:0.8.4"

我们将firebase-configlib从11.2.0 升级到11.6.2并jobdispatcher在之前的版本和新版本之间添加了lib,我们开始看到崩溃.我已经四处寻找,但没有看到任何关于这个问题的现有对话,如果有人有洞察力,我们真的很感激.谢谢!

Answer 1

我从firebase团队得到了我发送的有关此问题的错误报告的正式答复:

是的,你是对的.这是Firebase SDK 11.6.0以后的问题.
我们的工程师目前正在针对此问题进行修复,但目前我无法分享任何细节或时间表.

在此期间,我建议您使用较旧版本的Firebase SDK.

您可以查看我们的发行说明以获取进一步的更新.
