Everytime you reinstall or clear data of your application, your token is generated again.
Log your token everytime onTokenRefresh() is called as described here.
So, get your token and use it to send your push notification :D

So I tried adding a user to a firebase group to be able to send data notification to multiple user on a simple app that show the notification when it receives it.
My problem is that following the firebase documentation I tried adding the following line to my mainactivity.java
FirebaseMessaging.getInstance().subscribeToTopic("weather")
But android studio told me that the .getInstance couldn't be called/"Cannot resolve symbol 'getInstance'é it so I don't know what to do to make it work
edit:
The app build.gradle:
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.shayru.myapplication"

The Project build.gradle :
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'

}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
and if needed this is what the mainactivity does :
package com.shayru.myapplication;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.google.firebase.messaging.FirebaseMessaging;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
FirebaseMessaging.getInstance().subscribeToTopic("News");
}
The problem is not with Firebase, rather its with your code. Subscribe to the topic in your onCreate() method, not outside a method.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FirebaseMessaging.getInstance().subscribeToTopic("News");
}
I'm new to android studio and I'm trying to set up firebase messaging but I keep getting the error in the message receiver class:
cannot resolve FirebaseMessagingService

Apparently you have the wrong import, From docs it should be
import com.google.firebase.messaging.FirebaseMessagingService;
instead of
import FirebaseMessagingService;
I am creating an application class to use Firebase in my complete application. However in the import line error occurs highlighting 'firebase' in red.
I have looked everywhere but cannot make out the problem.
Code:
package com.mobility.mobilityindia;
import android.app.Application;
import com.firebase.client.Firebase; <--- firebase is red here
public class MobilityIndia2 extends Application{
#Override

super.onCreate();
Firebase.setAndroidContext(this); <---- Firebase is red here

The code you have is for an old version of the Firebase SDK (1.x or 2.x), while you're importing the latest version.
If you follow the latest documentation or the latest Android codelab, you won't need the Firebase.setAndroidContext() anymore and will get imports that start with com.google.firebase.
I'm a new MPAndroidChart user.
The examples I have found on-line and the Wiki here all give the setDescription() prototype as:
setDescription(String desc)`
However, mChart.setDescription(""); does not compile for me and AndroidStudio->Go To Declaration tells me the declaration for setDescription defined in Chart.java is :
public void setDescription(Description desc) {
this.mDescription = desc;
}
And the Description constructor in Description.java does not take a String.
How do I set the description (or at least turn it off)? Am I pointing to the wrong libraries?
Here is my app's gradle file:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
allprojects {
repositories {
maven { url "https://jitpack.io" }
}
}
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
And, the module gradle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.example.android.nbmc_hbmc"
minSdkVersion 19
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.github.PhilJay:MPAndroidChart:v3.0.1'
compile 'com.google.android.gms:play-services-auth:10.0.1'
compile 'pub.devrel:easypermissions:0.2.1'
testCompile 'junit:junit:4.12'
}
And this is my chart code. It compiles and shows the chart but it has the Description Label "Description Label" that I can't change or turn off.
import com.github.mikephil.charting.charts.LineChart;
import com.github.mikephil.charting.components.Description;
import com.github.mikephil.charting.data.Entry;
import com.github.mikephil.charting.data.LineData;
import com.github.mikephil.charting.data.LineDataSet;
import com.github.mikephil.charting.interfaces.datasets.ILineDataSet;
import java.util.ArrayList;
import java.util.List;
import static com.example.android.nbmc_hbmc.R.id.chart;
public class NbmcEcgGraphActivity extends Activity {
private RelativeLayout mainLayout;
private LineChart mChart;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ecggraph);
mainLayout = (RelativeLayout) findViewById(R.id.activity_ecggraph);
// Create new line chart
LineChart mChart = (LineChart) findViewById(chart);
mChart.setDescription(new Description());
mChart.setNoDataText("No Data Yet");
It looks like the wiki is out of date!
The correct syntax in MPAndroidChart 3.0.1 is
mChart.getDescription().setText("Description of my chart");

I keep getting a "unresolved reference: FacebookCallback" error when I am trying to implement the code attached in the picture.
I am trying to set up facebook login as instructed in this link: https://developers.facebook.com/docs/facebook-login/android#addbutton
I am new to Kotlin but I can't see what I'm doing wrong here.

futhermore, here is the equivalent code I am trying to execute but written in plain Java (which works just fine):
import com.facebook.FacebookCallback;
import com.facebook.FacebookException;
import com.facebook.login.LoginResult;
public class Actv extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_actv);
FacebookCallback<LoginResult> facebookCallback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException error) {
}
};
}
}
A proper way to anonymously implement FacebookCallback in Kotlin is as follows:
val facebookCallback = object : FacebookCallback<LoginResult> {
override fun onSuccess(loginResult: LoginResult) {
}
override fun onCancel() {
}
override fun onError(error: FacebookException) {
}
}
Object Expressions and Declarations documentation provides all necesary details.
