React-native setup of Moengage errors when running android: package MoEngage does not exist

Question

I'm installing MoEngage sdk and react-native-moengage packages on my react native app, but I have been unable so far to run the app even after following the guide in the official site

Removing everything related to moengage makes the app run again, so I don't believe it's a different package or bad config

I tried cleaning gradle, running from CLI, running from android studio, running in a physical device, changing the versions of appcompat (breaking other things, so I'd rather not do that again)... Up to no avail.

Currently running:

• Windows 10 64bits

• React native 0.59.8. It's not a new app, it started in 0.55.4 and migrated to 0.59.8 over time.

• Gradle build tools 3.3.0 and gradle version 4.10.1-all

// app/build.gradle

android {
    compileSdkVersion 28
    buildToolsVersion '28.0.3'
    ...
}
...
dependencies {
    implementation project(':react-native-moengage')
    implementation 'com.moengage:moe-android-sdk:+'
    implementation fileTree(dir: "libs", include: ["*.jar"])    
    implementation "com.android.support:appcompat-v7:28.0.0"
    implementation "com.facebook.react:react-native:+"  // From node_modules
    ...
}

// settings.gradle

include ':react-native-moengage'
project(':react-native-moengage').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-moengage/android')

//MainApplication.java

...
import com.moengage.react.MoEReactPackage;
...


public class MainApplication extends Application implements ReactApplication {
...

  @Override
  public boolean getUseDeveloperSupport() {
    return BuildConfig.DEBUG;
  }

  @Override
  protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
            new MoEReactPackage(),
    );
  }
  };

  @Override
  public void onCreate() {
    super.onCreate();
    MoEngage moEngage =
        new MoEngage.Builder(this, "XXX")
            .build();
    MoEngage.initialise(moEngage);
  }

So far I've only gotten the following message

...project\android\app\src\main\java\io\lifevision\MainApplication.java:95: error: cannot find symbol
    MoEngage moEngage =
    ^
  symbol:   class MoEngage

Answer 1

Import statement for MoEngage.java is missing. Below is the required import statement

import com.moengage.core.MoEngage;

I would recommend you to enable auto-import in your IDE(Android Studio) it will help you manage the imports.

Let me if this does not solve your issue. Alternatively you can write to us at [email protected]
