如何在 android 活动中获取 Firebase 令牌？

德鲁桑

我正在使用setToken(FirebaseInstanceId.getInstance().getToken())代码来获取令牌，但出现以下错误

java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/android/gms/common/util/zzv;

构建.gradle

dependencies {
    implementation 'de.hdodenhof:circleimageview:2.2.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.squareup.retrofit2:retrofit:2.4.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
    implementation 'com.squareup.okhttp3:okhttp:3.10.0'

    implementation 'com.google.firebase:firebase-auth:16.0.5'

    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    annotationProcessor "android.arch.lifecycle:compiler:1.1.0"

    implementation 'com.google.firebase:firebase-messaging:11.8.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'net.bohush.geometricprogressview:geometricprogressview:1.1.1'
    implementation project(path: ':andoird-sdk')
    implementation project(path: ':opentok-android-sdk-2.16.3')

    implementation 'com.android.support:multidex:1.0.3'
}

apply plugin: 'com.google.gms.google-services'

上面的代码是我的build.gradle。帮我解决问题。

您需要使用 FirebaseMessagingService 来获取令牌 .. 您将获得令牌到它自己的方法中

public class MyFirebaseMessagingService extends FirebaseMessagingService {

@Override
    public void onNewToken(final String token) {

/// you will get token here you 
    enter code here

}

}
