Question

RN 0.55.4
Gradle: 2.2.3

Android上有一个问题。我们更新了一些node_modules，并对0.55版做出了本机反应，一切看起来都还不错，但是当我们将此新版本发布到Google Beta中时，然后下载它进行测试，该应用始终在首次运行时崩溃。我们再次运行它，一切正常，应用程序正常运行。而且我们不知道怎么了从fabric.io得到的错误仅在从游戏中下载该应用程序时发生一次。

这也同时发生

我们的ProGuard应用规则

Answer 1

致命异常：java.lang.RuntimeException：无法启动接收器tv.dailyme.android.core.receiver.Autostart：java.lang。 NullPointerException ：

尝试调用虚拟方法'android.database.sqlite.SQLiteDatabase android.content.Context。 openOrCreateDatabase （java.lang.String，int，android.database.sqlite.SQLiteDatabase $ CursorFactory，android .database.DatabaseErrorHandler）'

关于空对象引用

它出现，好像您的ProGuard配置可能不足以不混淆某些内容。

您可以在类!= null中添加一个tv.dailyme.android.core.receiver.Autostart检查，以便至少不产生该NPE的抛出。似乎需要改进ProGuard -keep规则。

从Google Play下载后，应用首次启动时会崩溃（ExceptionInInitializerError）
