javascript - 活动类 {rcm.samapp/com.comp.android.ui....} 不存在

Question

我正在尝试集成反应本机和本机 android 应用程序。

应用程序 build.gradle 中的 applicationId 是rcm.samapp

清单标签中的包是com.comp.android.

SplashActivity.kt 中的第 1 行是package com.comp.android.ui

活动是清单看起来像：

 <activity
      android:name=".ui.SplashActivity"
      android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
 </activity>

遵循官方 RN 文档后，当我尝试通过react-native run-android --appId rcm.samapp --main-activity ui.SplashActivity命令运行它时，它会抛出此错误：

Starting: Intent { cmp=rcm.samapp/com.comp.android.ui.SplashActivity }
Error type 3
Error: Activity class {rcm.samapp/com.comp.android.ui.SplashActivity} does not exist.

可能是什么原因和解决方法？

您有一些自定义构建变体applicationIdSuffix正在更改包名称。您也应该在run-android命令中设置它们。

据我了解，您需要运行development变体。所以设置--variant development。applicationIdSuffix在development变体中是.debug. 将其指定为--appIdSuffix debug。

变体的完整命令development是：react-native run-android --appId rcm.samapp --main-activity ui.SplashActivity --variant development --appIdSuffix debug
