HMS NoClassDefFoundError Android

I’m using HMS plugin for Android Studio.

I have a class called MyFirebaseMessagingService which receives notifications from Firebase.

it used to be like :

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

public class MyFirebaseMessagingService extends FirebaseMessagingService {
...
}

after conversion:

import org.xms.f.messaging.ExtensionMessagingService;
import org.xms.f.messaging.RemoteMessage;

public class MyFirebaseMessagingService extends ExtensionMessagingService {
...
}

After converting the code, I had the following problem :

 Caused by: java.lang.NoClassDefFoundError: Failed resolution of: Lorg/xms/f/messaging/ExtensionMessagingService


 Caused by: java.lang.ClassNotFoundException: Didn't find class "org.xms.f.messaging.ExtensionMessagingService" on path: DexPathList

I found a suggested solution in Huawei support, but it didn’t work!

(Handle the exception) link : https://developer.huawei.com/consumer/en/doc/development/Tools-Guides/map-conversion-0000001050062227

Suggested solution :

Add the following configuration to app/build.gradle:

android {
    defaultConfig {
        multiDexEnabled false
    }
}

btw I already clean and rebuild the project. Also, I tried to restart and invalidate.

Answer

After trying almost everything I solved the problem. In order to help as many people as possible, I will write the steps you need to follow to get HMS map working :

1. Create Huawei developer account: https://id5.cloud.huawei.com/CAS/portal/userRegister/regbyemail.html

2. Create a project and an app in Huawei Developer console, then get agconnect-service.json (After downloading make sure it is .json) file: https://developer.huawei.com/consumer/cn/service/josp/agc/index.html#/

you can watch this video to help you: https://www.youtube.com/watch?v=BQbFlP4gRN8&t=1s

3. Download and install HMS converter plugin from Android Market place. The plugin will ask you to restart Android Studio.

4. Before converting the project make sure to create a backup locally or on Github.

5. The following video will help you understand how to convert google APIs. Important note: @5:50 in the video the instructor will choose "To HMS API", You need to select "Add HMS API (GMS API First)". Also, @6:53 in the video the instructor will click on automatic convert for all files. From a Personal Experience, it is better to convert files one by one manually. Actually, auto-convert is the cause of the issue I encountered! https://www.youtube.com/watch?v=1b1Ap5xQHm4&t=357s

6. Make sure HMS converter added the following lines to your build:gradle/Project:

    buildscript {
    repositories {
    ...
   
   // added by hms converter
   maven {url 'https://developer.huawei.com/repo/'}
   }
   
   dependencies {
    ...
   
    // added by hms converter
    classpath 'com.huawei.agconnect:agconnect-apms-plugin:1.4.1.305'
    classpath 'com.huawei.agconnect:agcp:1.2.1.301'
     }
   }
   
   allprojects {
    repositories {
    ...
   
    // added by hms converter
    maven {url 'https://developer.huawei.com/repo/'}
     }
    }
   

7. Make sure HMS converter added the following lines to your build:gradle/App:

    android {
    ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
     }
   }
   
   
   
    dependencies {
    // added by hms converter
    implementation project(':xmsadapter')
    implementation project(':xmsadapter:xmsaux')
    compileOnly project(':xmsadapter:xmsaux:xapi')
   
    ...
   
    //added by hms converter
    implementation 'com.huawei.hms:maps:5.3.0.300'
    implementation 'com.huawei.hms:location:6.0.0.302'
   
   
   }
   
   //added by hms converter
   apply plugin: 'com.huawei.agconnect'
   apply from: '../xmsadapter/scripts/productFlavor.gradle'
   

8. Make sure HMS converter added the following lines to your Settings.gradle:

   include ':app'
   ...
   // added by hms converter
   include ':xmsadapter', ':xmsadapter:xmsaux', ':xmsadapter:xmsaux:xg', ':xmsadapter:xmsaux:xh', ':xmsadapter:xmsaux:xapi'
   

9. Add the following rules to proguard-rules.pro in case minifyEnabled is true:

       #<HMS Rules>
       -ignorewarnings
       -keepattributes *Annotation*
       -keepattributes Exceptions
       -keepattributes InnerClasses
       -keepattributes Signature
       -keepattributes SourceFile,LineNumberTable
       -keep class com.hianalytics.android.**{*;}
       -keep class com.huawei.updatesdk.**{*;}
       -keep class com.huawei.hms.**{*;}
       -keep class com.huawei.agconnect.**{*;}
       -keep interface com.huawei.agconnect.**{*;}
       -keep class com.huawei.hmf.**{*;}
   
       -keep class com.google.android.gms.**{*;}
       -keep interface com.google.android.gms.**{*;}
   
       -keep class com.google.firebase.**{*;}
       -keep interface com.google.firebase.**{*;}
   
       -keep class org.xms.**{*;}
       -keep interface org.xms.**{*;}
   
       #for map
       -keep class * extends androidx.fragment.app.Fragment{*;}
       -keep class org.xms.g.maps.ExtensionMapOptions{*;}
       -keep class com.huawei.hms.maps.HuaweiMapOptions{*;}
       -keep class com.google.android.gms.maps.GoogleMapOptions{*;}
       -keep interface org.xms.g.maps.OnMapReadyCallback{*;}
       -keep interface com.huawei.hms.maps.OnMapReadyCallback{*;}
       -keep interface com.google.android.gms.maps.OnMapReadyCallback{*;}
       -keep class org.xms.g.maps.StreetViewPanoramaOptions{*;}
       -keep class com.google.android.gms.maps.OnStreetViewPanoramaReadyCallback{*;}
       -keep class com.huawei.hms.maps.OnStreetViewPanoramaReadyCallback{*;}
       -keep interface org.xms.g.maps.OnStreetViewPanoramaReadyCallback{*;}
       -keep interface com.google.android.gms.maps.OnStreetViewPanoramaReadyCallback{*;}
       -keep interface com.huawei.hms.maps.OnStreetViewPanoramaReadyCallback{*;}
       -keep class com.huawei.hms.dynamicloader.** { *; }
       -keep class com.huawei.hms.feature.dynamic.** {*;}
       -keep class com.huawei.hms.feature.** { *;}
   
   
   
       #</HMS Rules>
   

10. Clean then Rebuild the project, you may need to “restart and invalidate” Android studio.
