问题
I'm just trying to write a message in database, then I have this error when I run the app
As I know I already added necesary dependencies in my gradle
gradle at module level, I already added Firebase Core, Firebase database and so on:
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:28.0.0-rc02'
implementation 'com.android.support:design:28.0.0-rc02'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:support-vector-drawable:28.0.0-rc02'
implementation 'com.android.support:support-v4:28.0.0-rc02'
implementation 'com.firebaseui:firebase-ui-auth:5.0.0'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-auth:16.2.1'
implementation 'com.google.android.gms:play-services-maps:16.1.0'
implementation 'com.google.firebase:firebase-core:16.0.8'
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 'com.squareup.picasso:picasso:2.71828'
implementation 'de.hdodenhof:circleimageview:3.0.0'
implementation 'com.github.bumptech.glide:glide:4.9.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
implementation 'com.facebook.android:facebook-android-sdk:[4,5)'
implementation 'com.facebook.android:facebook-android-sdk:4.42.0'
implementation 'com.android.support:multidex:1.0.3'
}
apply plugin: 'com.google.gms.google-services'
gradle at project level
buildscript {
repositories {
google()
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.3.0'
classpath 'com.google.gms:google-services:4.2.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
And finally code when I have the issue:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
/*In this line i got the error in Logcat -> */FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference myReference = database.getReference("message");
myReference.setValue("Hello, world!");
}
This is the error that I got when i run the app

回答1:

implementation 'com.google.firebase:firebase-database:17.0.0'
Hope it will help to someone.
