React Native簽名版本構建，但無法啓動

Question

我試圖在發佈模式下運行我的反應原生應用程序。 APK是按照文檔簽名的，並且第一次運行正常（在模擬器和實際設備中）。

儘管一些更新（添加庫，改變gradle這個配置，開發更多的代碼）釋放安裝不工作後：

• 在調試模式下，所有工程確定（建設，模擬器和真正的手機）
：
• 在釋放模式在啓動（模擬器和真正的手機）

在我看到下面的錯誤日誌中建立正常，但應用程序崩潰

這裏是我的版本文件夾下的AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:tools="http://schemas.android.com/tools" 
     package="com.myfakeappname"> 

     <application 
     android:name=".MainApplication" 
     > 

     </application> 
</manifest> 

編輯：添加proguard-rules.pro

# Add project specific ProGuard rules here.

最有可能你啓用ProGuard，並將一些類被混淆，使他們不在運行時發現。

嘗試在發佈配置中禁用它，然後重試。如果你需要，發佈你的proguard.properties文件。
