我知道这个问题是重复的，已经被问了很多遍，我阅读了所有问题的所有答案，但没有一个起作用。我正在尝试构建React本机应用进行发布，但出现此错误
➜ android git:(master) ✗ ./gradlew assembleRelease
> Task :preBuild UP-TO-DATE
> Task :preReleaseBuild UP-TO-DATE
> Task :compileReleaseAidl NO-SOURCE
> Task :compileReleaseRenderscript NO-SOURCE

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':generateReleaseBuildConfig'.
> Cannot read packageName from /run/media/christopher/warzone/projects/mobile/in_development/fundiapp/mobileapp/android/src/main/AndroidManifest.xml

我从提出的问题中尝试了所有解决方案，但都无济于事。这些是我的文件

答案 0 :(得分：0)
您在build.gradle中缺少applicationId字段，请在defaultConfig（“ com.mobileapp”）中添加applicationId-您的包名称-或您想要的任何包名称：
defaultConfig {
applicationId "com.mobileapp"
minSdkVersion rootProject.ext.minSdkVersion
targetSdkVersion rootProject.ext.targetSdkVersion
versionCode 1
versionName "1.0"
}
