uni-app Activity class {com.android.UniPlugin/io.dcloud.PandoraEntry} does not exist

The error message you’re encountering, uni-app Activity class {com.android.UniPlugin/io.dcloud.PandoraEntry} does not exist, typically indicates that the specified activity class cannot be found in your Android project. This issue often arises when there is a mismatch or misconfiguration in the Android manifest file or when the required dependencies are not properly included in your project.

Here are some steps to troubleshoot and resolve this issue:

1. Check the AndroidManifest.xml File

• Ensure that the AndroidManifest.xml file in your project correctly declares the PandoraEntry activity.
• The entry should look something like this:

  <activity
      android:name="io.dcloud.PandoraEntry"
      android:launchMode="singleTask"
      android:configChanges="orientation|keyboardHidden|screenSize"
      android:theme="@style/TranslucentTheme">
      <intent-filter>
          <action android:name="android.intent.action.MAIN" />
          <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
  </activity>
  

• If the PandoraEntry activity is missing or incorrectly configured, add or correct it.

2. Verify Dependencies

• Ensure that the uni-app SDK and related dependencies are properly included in your project.
• If you’re using Gradle, check your build.gradle file for the required dependencies. For example:

  dependencies {
      implementation 'io.dcloud:uniplugin:latest-version'
      // Add other dependencies as needed
  }
  

• If the dependencies are missing, add them and sync your project.

3. Rebuild the Project

• Clean and rebuild your project to ensure that all resources and configurations are correctly applied.
  • In Android Studio, go to Build > Clean Project and then Build > Rebuild Project.

4. Check for ProGuard/R8 Issues

• If you’re using ProGuard or R8 for code shrinking and obfuscation, ensure that the PandoraEntry class is not being removed.
• Add a rule to your proguard-rules.pro file to keep the class:

  -keep class io.dcloud.PandoraEntry { *; }
  

5. Update uni-app SDK

• If you’re using an older version of the uni-app SDK, there might be compatibility issues. Update to the latest version of the SDK.

6. Check for Custom Configurations

• If you’ve made custom configurations to your project, ensure they don’t interfere with the PandoraEntry activity.
• For example, if you’re using custom build flavors or product flavors, ensure they are correctly configured.

7. Reinstall the Project

• If the issue persists, try deleting the build folder and reinstalling the project:

  rm -rf build
  ./gradlew clean
  ./gradlew build
