java.lang.RuntimeException: Unable to create application com.ads.app.MyApplication: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.ads.app. Make sure to call FirebaseApp.initializeApp(Context) first.
Caused by: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.ads.app. Make sure to call FirebaseApp.initializeApp(Context) first.
1、检查项目\build.gradle
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'com.google.gms:google-services:4.2.0'
}
2、检查google-services.json是否放在app\目录下,必须保证google-services.json里面有当前包的包名
3、检查app\build.gradle
dependencies {
implementation 'com.google.android.gms:play-services-auth:15.0.1'
implementation 'com.google.firebase:firebase-core:17.2.0'
implementation 'com.google.firebase:firebase-iid:20.0.0'
implementation 'com.google.firebase:firebase-messaging:20.0.0'
implementation 'com.android.installreferrer:installreferrer:1.0'
}
apply plugin: 'com.google.gms.google-services'是否放在app\build.gradle底部
4、检查Application
@Override
public void onCreate() {
super.onCreate();
FirebaseApp.initializeApp(this);
initFirebase();
}
private void initFirebase(){
FirebaseInstanceId.getInstance().getInstanceId()
.addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
@Override
public void onComplete(@NonNull Task<InstanceIdResult> task) {
if (!task.isSuccessful()) {
MLog.e( "getInstanceId failed"+task.getException());
return;
}
String token = task.getResult().getToken();
}
});
}
