Ionic Codepush Cordova not available after sync

i'm trying to implement Code-Push from AppCenter into my Ionic v4 App. (ref)
I'm stuck on the following Problem: I can update the App, but when i close the App after that and open again it is the old Version again and it says:
Updade ignored, because it was rollbacked
So somehow the update is rolled back after i close the App. After searching for this problem i found that i have to run
this.codePush.notifyApplicationReady()
on application start. I added this to my code, but it doesn't work either. If i run the Application on a Android Emulator and open the Logs, AFTER the Update it says:
cordova_not_available
So it makes sense that the notifyApplicationReady doesn't work, but why is cordova unavailable?
initializeApp() {
this.platform.ready().then(() => {
this.statusBar.styleDefault();
this.codePush.notifyApplicationReady().then(value => {
console.log(value);
});
this.codePush.sync({
deploymentKey: 'MY_KEY',
installMode: InstallMode.IMMEDIATE
}).subscribe(status => {
console.log(status);
});
this.splashScreen.hide();
});
}

Do u use command ionic build --prod ? this conmand will not include cordova.js,so if app installed this package the cordova will not available, in ionic4 i use ionic cordova build android --prod to include the cordova.js and then release the www file to code push serve.it wokrs!

Ionic3-Cordova-UWP : Ionic Storage doesn’t work when app is running

I have a problem with Ionic storage in my Ionic App for Windows (UWP app). I already tested and deployed my app for Android without any trouble.
Now I would like to generate an UWP app.
The app I’m developing is a workshop’s dashboard. The indicators change every day and I need to save them from one day to another. To do this I usethe storage module of Ionic.
When launching the command
$ionic serve
the app responds exactly as it should in the web browser (Firefox). From one launch to another my data are still there.
When I use
$ionic cordova run windows
the installation and launch steps of my app work fine. Every function of my app runs fine, but the call to storage (get and set) doesn’t work : when I close, and then reopen it as an autonomous application, I loose all data every time. It is the same when I run the app from Visual Studio.
Moreover, I write some console.log in the result of the promise and none of them is written in the Javascript console. It is like Windows does not recognize the command.
I tried with Visual Studio 2015 Update 3 and Visual Studio 2017, the result is identical. I followed the recommendation of Ionic Doc and add the target platform windows10 in the config.xml.
Does anyone have an idea of what I’m doing wrong ? Is there an incompatibility between Windows and Ionic ?
Thanks for any help.
Config :
Windows 10 64-bits
Ionic CLI: 3.19.1
Cordova CLI : 8.0.0
Node : v6.11.2
Visual Studio Community 2017 (15.5.27130.2036)
Extract of my code maPage.ts :
import { Storage } from '#ionic/storage';
export class maPage {
constructor(public storage: Storage) {
this.downloadData();
}
ionViewWillLeave()
{
this.saveData();
}
TabData = {
id: 0,
label: '',
Tab1: [],
Tab2: [],
attri1 : 0,
attri2: false
}
Param = {
Objet1: {NbObj1: 7},
Objet2: {NbObj2: 5}
}
saveData()
{
var Data: object;
Data =
{
TData: this.TabData,
TParam: this.Param
}
this.storage.set('Data', Data).then(_=> {
console.log('Backup done!');
}, error => {
console.log('erreur : ', JSON.stringify(error))
});
}
downloadData()
{
this.storage.ready().then(()=>{
console.log('storage ready');
this.storage.get('Data').then((val) => {
this.TabData = val.TData;
this.Param = val.TParam;
console.log('Récupération terminée !');
}).catch(erreur => {
console.log('La variable Data est vide ou n\'existe pas!');
console.log('erreur : ', JSON.stringify(erreur));
}).catch(err => {
console.log('storage not ready');
console.log('err : ', JSON.stringify(err));
});
}
}

On Windows platform, console.log is not supported. To do that, you should install cordova-plugin-console, or need to use alert function.
Regarding storage, I am suggesting you could use localstorage or cordova-sqlite-storage.

How to debug native cordova plugins on ionic app?

I created a simple app with possibility to select photo from mobile phone using #ionic-native/photo-library. Now I want to debug it, print some console logs and check if photo is loaded properly:
private selectPhoto() {
this.photoLibrary.requestAuthorization().then(() => {
this.photoLibrary.getLibrary().subscribe({
next: library => {
library.forEach((libraryItem) => {
console.log(libraryItem) // i want to print it
})
},
error: err => {},
complete: () => { console.log('could not get photos'); }
})
})
.catch(err => console.log(err));
}
Unfortunatelly, I receive an error:
Native: tried calling PhotoLibrary.requestAuthorization, but Cordova is not available. Make sure to include cordova.js or run in a device/simulator
I read that native plugins must be tested on device but how to get output from code in my console? When I install apk I do not have any debug information.
Regards

The error means that the plugin won't properly work unless cordova.js is already loaded. This happens because cordova.js is the one responsible for loading your plugins, so if you are calling any of it before cordova is ready it just won't work.
You should use either:
document.addEventListener('deviceready', DeviceReady, false);
function DeviceReady() {
//your plugin code here...
}
or
$ionicPlatform.ready(function() {
//your plugin code here...
});
To properly debug an Android/iOS build with the help of a browser console (chrome/safari) make sure that you're building a debug apk/ipa with the option --debug at the CLI:
$ionic build android/ios --debug
I hope this may help you out =)

cordova.plugins.locationManager.enableBluetooth() Not working in android

I am trying to enable my phone bluetooth via ionic app. I am calling something like this:
cordova.plugins.locationManager.enableBluetooth()
But not enabling and making any error also. Following is my app.js code. Please help out.
import {App, Platform} from 'ionic-framework/ionic';
import {TabsPage} from './pages/tabs/tabs';
#App({
template: '<ion-nav [root]="rootPage"></ion-nav>',
config: {} // http://ionicframework.com/docs/v2/api/config/Config/
})
export class MyApp {
static get parameters() {
return [[Platform]];
}
constructor(platform) {
this.rootPage = TabsPage;
platform.ready().then(() => {
StatusBar.backgroundColorByName('red');
console.log("App starting.");
cordova.plugins.locationManager.enableBluetooth();
});
}
}
Is there anything I am missing. My phone is One Plus One.
UPDATE:
Is there any particular configuration I have to in device to achieve
this in develop mode
App technical info
Ionic 2 & Angular 2
Plugin : com.unarin.cordova.beacon (Link)

I resolved this myself. Seems to be issue was with petermetz/cordova-plugin-ibeacon, I was using 25days older plugin.
First removed the existing plugin by running by going into project root folder:
sudo cordova plugin rm com.unarin.cordova.beacon
Then again added the plugin (basically I updated my plugin):
sudo cordova plugin add https://github.com/petermetz/cordova-plugin-ibeacon.git
After that everything started working fine.
Thanks.

Phonegap build - Facebook connect plugin - Invalid android_key parameter error

I'm running example code (found below) through phonegap build to produce an android apk.
https://github.com/phonegap-build/FacebookConnect/blob/master/example/Simple/index.html
When I try to log into facebook through the app on an android device (with the facebook app installed), I get this error:
Invalid android_key parameter J4INwYsuTyQ_LJc1d3WZ2HReg7M does not match any allowed android key. Configure your app key hashes at http://developers.facebook.com/apps/'app id'
I have copy-pasted this key into the key hashes section of my app's android settings but it still throws the same error when I try to log in using the app.
How can I get this app to log into facebook successfully?
OR: What is another way to enable an android app to log into facebook using phonegap?
Here are some things I have done:
In my facebook app's settings:
Set 'Package name' to the 'widget id' found in my phonegap config.xml.
Set 'Class name' to the Package name with '.ProjectActivity' appended to it.
Enabled 'Single Sign on' and disabled 'Deep linking'.
Made the app open to the public (through the 'Status & Review' section.
In my phonegap config.xml (found in the /www directory in phonegap project):
Entered APP_ID as the ID found in my facebook app dashboard
Entered APP_NAME as the 'Namespace' found in my facebook app settings
In my phonegap build app settings:
Made a keystore (using this answer: https://stackoverflow.com/a/19315975/1696114) and used it to generate a release apk.

I think you should use facebook phonegap plugin as your authentication.
Download and install into your cordova project.
https://github.com/phonegap/phonegap-facebook-plugin
Use this command to install it.
cordova plugin add https://github.com/phonegap/phonegap-facebook-plugin.git --variable APP_ID="xxxxxxxxxxxxx" --variable APP_NAME=“xxxxxxxx”
Then setup your facebook app here:
http://developers.facebook.com/apps/
Then make sure you have this script in your project.
cdv-plugin-fb-connect.js
facebook-js-sdk.js
After that, paste this code into your main script
if ((typeof cordova == 'undefined') && (typeof Cordova == 'undefined')) alert('Cordova variable does not exist. Check that you have included cordova.js correctly');
if (typeof CDV == 'undefined') alert('CDV variable does not exist. Check that you have included cdv-plugin-fb-connect.js correctly');
if (typeof FB == 'undefined') alert('FB variable does not exist. Check that you have included the Facebook JS SDK file.');
FB.Event.subscribe('auth.login', function(response) {
//alert('auth.login event');
});
FB.Event.subscribe('auth.logout', function(response) {
//alert('auth.logout event');
});
FB.Event.subscribe('auth.sessionChange', function(response) {
//alert('auth.sessionChange event');
});
FB.Event.subscribe('auth.statusChange', function(response) {
//alert('auth.statusChange event');
});
function getSession() {
alert("session: " + JSON.stringify(FB.getSession()));
}
function getLoginStatus() {
FB.getLoginStatus(function(response) {
if (response.status == 'connected') {
alert('logged in');
} else {
alert('not logged in');
}
});
}
var friendIDs = [];
var fdata;
function logout() {
FB.logout(function(response) {
alert('logged out');
window.location.replace("#login");
});
}
function login() {
FB.login(
function(response) {
if (response.authResponse) {
alert('logged in');
FB.api('/me', function(me) {
if (me.id) {
localStorage.id = me.id;
localStorage.email = me.email;
localStorage.name = me.name;
window.location.replace("#home");
}
else {
alert('No Internet Connection. Click OK to exit app');
navigator.app.exitApp();
}
});
} else {
alert('not logged in');
}
}, {
scope: "email"
});
}
document.addEventListener('deviceready', function() {
try {
//alert('Device is ready! Make sure you set your app_id below this alert.');
FB.init({
appId: "appid",
nativeInterface: CDV.FB,
useCachedDialogs: false
});
document.getElementById('data').innerHTML = "";
} catch (e) {
alert(e);
}
}, false);
use login() to login . Enjoy!!

I successfully made an app which can log into facebook by using the phonegap-facebook-plugin and by building my cordova/phonegap project locally.
I made a new cordova project and added the android platform for this project, following the instructions here: http://docs.phonegap.com/en/3.4.0/guide_overview_index.md.html#Overview
In doing this I discovered I had made my previous project using an older cordova version (3.1) un-intentionally and that I hadn't installed the cordova command line interface. There may have been other issues with the way I made my first project.
I then added the phonegap-facebook-plugin found here: https://github.com/phonegap/phonegap-facebook-plugin using this command (from my project location):
cordova plugin add https://github.com/phonegap/phonegap-facebook-plugin.git --variable APP_ID="xxxxxxxxxxxxx" --variable APP_NAME=“xxxxxxxx”
(replacing APP_ID value with my facebook app id and APP_NAME value with my app's namespace).
I then replaced my index.html with the example index file found at the phonegap-facebook-plugin github page + /blob/master/example/Simple/index.html (replacing the app_id value with my app id).
I then ran the app straight to my android device using:
cordova run android
In this app, I'm able to use the interface provided by the example to login, post to my own or friends' walls etc. Using this new project (with updated cordova version) I may be able to use phonegap build but I haven't tried yet.
Thanks to Dato' Mohammad Nurdin for the suggestion to use this plugin.
