英文:
React Native App crashing on release mode but working fine debug mode
问题
我的React Native应用几天前在发布和调试模式下都能正常运行，但从昨天开始，在发布模式下启动后就会不断崩溃，但在调试模式下完全正常。
当我运行
adb logcat *:E
它给了我以下日志，但我在互联网上找不到相关的信息

我尝试生成日志并在互联网上搜索日志中出现的错误，但没有找到任何信息。

得分: 0
这个错误是由于在./android/app/src/main/assets目录中缺少index.android.bundle文件导致的。
第一步：
如果android/app/src/main/目录中不存在assets文件夹，请创建它。
第二步：
运行以下命令行：
react-native bundle --platform android --dev false --entry-file index.js --bundle-output ./android/app/src/main/assets/index.android.bundle --assets-dest ./android/app/src/main/res/
第三步：
以发布模式编译应用程序。
英文:
this error is caused by the absence of the index.android.bundle file in the ./android/app/src/main/assets directory
First step:
Create the assets folder if it does not exist in the android/app/src/main/ directory
Second step:
Run the following command line:
react-native bundle --platform android --dev false --entry-file index.js --bundle-output ./android/app/src/main/assets/index.android.bundle --assets-dest ./android/app/src/main/res/
Step three:
Compile the application in release mode
