XMLHttpRequest not firing/calling any [on] callback in react-native Android

react-native v0.63.4 android XMLHttpRequest not calling any [on] callback after sending the request but if I check after in the request data, I find that ready state is DONE and the response status is 200 OK and the data is there but none of the callbacks gets fired.
Here is the code I'm testing with.
var request = new XMLHttpRequest();
request.onabort = () => {
console.warn("ABORTED");
};
request.onerror = () => {
console.warn("ERROR");
};
request.onloadstart = () => {
console.warn("LOAD START");
};
request.onloadend = () => {
console.warn("LOAD END");
};
request.ontimeout = () => {
console.warn("TIMEOUT");
};
request.onload = () => {
console.warn("LOAD");
};
request.onreadystatechange = (e) => {
console.warn("STATE CHANGE", request.status);
if (request.readyState !== 4) {
return;
}
if (request.status === 200) {
console.warn("success", request.responseText);
} else {
console.warn("error");
}
};
request.open("GET", "https://api.github.com/", true);
request.send();
setTimeout(() => {
console.warn(JSON.stringify(request, null, 2)); // this successfully log all the response data.
}, 1000);

What I'm doing wrong?

Can't send notifications from Parse Server

I am trying to send push notifications from Bitnami Parse Server (3.1.2) hosted on AWS.
I have the server key and the sender ID from firebase in server.js.
Notifications work from the firebase console but not from parse server (neither from the dashbord nor from REST API). It says it's saved but Pushes Sent appear 0 even though I have two installations.
Any ideas?
Puhes Sent 0

Solution is to revert to previous FB SDK in build.gradle:
dependencies {
// ...
compile 'com.facebook.android:facebook-android-sdk:4.15.0'
}

delete this line: android:theme="#android:style/Theme.Translucent.NoTitleBar"
AndroidManifest.xml
<meta-data android:name="com.facebook.sdk.ApplicationId"
android:value="#string/facebook_app_id"/>
<activity android:name="com.facebook.FacebookActivity"

android:label="#string/app_name" />
<activity
<!-- If you want the custom tabs when the facebook website is oppened -->
android:name="com.facebook.CustomTabActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="#string/fb_login_protocol_scheme" />
</intent-filter>
</activity>
You'll see that with custom tabs enabled the facebook website will open with a tab in the top and it will occupy the whole screen. Without this the website will open like a pop up and you can still see the app in the background if you look at the corners.
Or if you want to keep this line you need to add tools:replace="android:theme" in your manifest. But I see no reason to keep this line (correct me if I am wrong).
<activity android:name="com.facebook.FacebookActivity"
android:configChanges=
"keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="#string/app_name"
android:theme="#android:style/Theme.Translucent.NoTitleBar"
tools:replace="android:theme"/>
For facebook login guide.
ADITIONAL
An additional tip while working with facebook login, you will notice that when you added the facebook dependecie, com.android.support:appcompat-v7:... gives a warning saying that you have dependecies with different versions. You need to override this dependencie in order to get rid of this error
implementation 'com.android.support:customtabs:27.1.1'

WiFi broadcast receiver not delivering in Android 7.1.1

Using Android-7.1.1, SDK-25.3.0
I am having problems with the WiFi-broadcast-receiver. Until Android-7.0.x everything worked well. But now, having updated to Android-7.1.1. with its newest SDK, my WiFi-broadcast-receiver does not return any values anymore.
The List<ScanResult> resultList = wifi.getScanResults(); returns 0 (instead of like before some valuable values). Why is this ??? What could the Android-update have caused or is there any mistake in my code ?? Any help appreciated!
Below is my code:
Setting up the WiFi-broadcast-receiver inside the Fragment (not full fragment but excerts...):
public class ScanTeachingFragment extends Fragment implements MyWifiReceiver.OnWiFiResultListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// set up WiFi Manager
this.wifiManager = (WifiManager) getActivity().getSystemService(Context.WIFI_SERVICE);
if (wifiManager.isWifiEnabled()) {
// register Broadcast-Receiver for WiFi
receiverWifi = new MyWifiReceiver(this.context);
IntentFilter filterWiFi = new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
getActivity().registerReceiver(receiverWifi, filterWiFi);
}
// setListener necessary otherwise null-pointer occurs in WiFiReceiver
receiverWifi.setListener(this);
}
private void ScanWifi() {
if (!IndoorNavHelpers.inEmulator()) {
wifiManager.setWifiEnabled(true);
wifiManager.startScan();
}
}
}
Here is the WiFi-broadcast-receiver implementation:
package com.xxxx.yyyy.broadcast_receiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.wifi.ScanResult;
import android.net.wifi.WifiManager;
import java.util.List;
public class MyWifiReceiver extends BroadcastReceiver {
private Context context;
OnWiFiResultListener resultListener;
// ScanFragment must implement this interface
public interface OnWiFiResultListener {
void scanWiFireceived(List<ScanResult> resultList);
}
// create setListener class (otherwise null-pointer occurs)
public void setListener(OnWiFiResultListener listener) {
this.resultListener = listener;
}
public MyWifiReceiver(Context context)
{
this.context = context;
}
// This method call when number of wifi connections changed
public void onReceive(final Context context, Intent intent) {
WifiManager wifi = (WifiManager)this.context.getSystemService(Context.WIFI_SERVICE);
List<ScanResult> resultList = wifi.getScanResults();
// ???????????????????????????????????????????????????????????
// Here resultList returns 0, WHY ????????????????????????????
// ???????????????????????????????????????????????????????????
// append newly found WiFi-scanResults to WiFiSniffing_File by calling callback-method in MainActivity
if(resultListener != null) {
resultListener.scanWiFireceived(resultList);
}
}
}

I finally found a solution: If I factory-reset my Nexus 5X and re-install Android Nougat 7.1.1, then my code works again ! No idea what corrupted the mobile install in the meantime ??? The above code therefore works now !

Turn on your GPS..
For Android 7 the permissions ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION are neccessary to get the Wi-Fi scan results. You also have to turn on location at device.

FirebaseInstanceIdService getToken returning null

Im trying to add FCM notifications to my app, but for some reason
FirebaseInstanceId.getInstance().getToken();
is returning null.
Since im not getting any stacktrace my best guess is that FirebaseInstanceIdService is not working
Google Play Services version: 9.6.1
Firebase-messaging version : 9.6.1
added json config file from FirebaseConsole (Tried single file with 2 clients inside it, one for debug and one for release build) and 2 files each for respective build
Iw applied google services plugin at the bottom of my modules gradle script
Included google services in projects root gradle script
Created 2 services from the officail docs:
public class MyFirebaseInsanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
#Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
PreferencesHelper.putSharedPreferencesString(Constants.User.PUSH_NOTIFICATIONS, refreshedToken);
Log.e("TOKEN", "Token: " + FirebaseInstanceId.getInstance().getToken());
}
}

Note that im using tools:node="replace" in my root application tag.
Is it possible that FirebaseInstanceIdService is not added to the manifest since it has the same intent filter as mine FirebaseInstanceService and thus not being called?
So my question here would be is there something wrong it the official docs or in my implementation that should cause the Instance token to be null?

After digging up thru old implementations of FCM and generated manifests, I can now say that manifest merger is the problem.
Solution for this problem is adding these classes to the apps manifest manualy
<activity
android:name="com.google.android.gms.common.api.GoogleApiActivity"
android:exported="false"
android:theme="#android:style/Theme.Translucent.NoTitleBar" />
<meta-data

android:value="#integer/google_play_services_version" />
<service

While I was doing the migration I had a problem, it was that I didn't receive any Notification. To solve this and If you have your GCM working, don't forget to include your sender ID when you get the Firebase Token. To consult this ID you have to navigate to your Firebase project and click Project Name. Click the Setting icon and select "Project Setting" menu Select "Could Messaging" tab and use sender ID on the page.
And when says to code this:
token = FirebaseInstanceId.getInstance().getToken();
You have to use this:
token = FirebaseInstanceId.getInstance().getToken("YOUR_SENDER_ID", "FCM");
It works for me, I hope this helps you ;)

This worked for me:
String token = FirebaseInstanceId.getInstance().getInstanceId().getResult().getToken();

First genarate "google-services.json" and Add this file in your android studio Like this projectFolder/APP/google-services.json
Add classpath to top level build.gradle
dependencies {
classpath 'com.android.tools.build:gradle:2.1.2'
classpath 'com.google.gms:google-services:3.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
Add following plugin and dependencies in app’s build.gradle
apply plugin: 'com.google.gms.google-services'
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.0.0'
compile 'com.google.firebase:firebase-core:9.4.0'
compile 'com.google.firebase:firebase-messaging:9.4.0'
}
Add following Firebase services in your java files
FirebaseIDService.java
package com.galleonsoft.firebase.push;
import android.util.Log;
import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;
public class FirebaseIDService extends FirebaseInstanceIdService {
private static final String TAG = "FirebaseIDService";
#Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
// TODO: Implement this method to send any registration to your app's servers.
sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String token) {
// Add custom implementation, as needed.
}
}
MyFirebaseMessagingService.java
package com.galleonsoft.firebase.push;
import android.util.Log;
import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
public class MyFirebaseMEssagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO: Handle FCM messages here.
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated.
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
}
}
Add service in your AndroidMainifest.xml file
<service android:name=".MyFirebaseMEssagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<service android:name=".FirebaseIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
