I want to exit the app when the device have no internet connection, but I use exitApp it nothing happened, here is my code:
constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen, private alertCtrl: AlertController, private network: Network, public deeplinks: Deeplinks, public events: Events) {
platform.ready().then(() => {
let disconnectSub = this.network.onDisconnect().subscribe(() => {
console.log('you are offline');
});
let connectSub = this.network.onConnect().subscribe(()=> {
console.log('you are online');
});
if(this.network.type === 'none' || this.network.type === 'unknown') {
let alert = this.alertCtrl.create({
title: "Internet Connection Problem",
subTitle:"Please Check Your Network connection",
buttons: [{
text: 'Ok',
handler: () => {
platform.exitApp();
}
}]
});
alert.present();
}
});
}
Anyone have experience before? Thanks.

I'm having trouble selecting the index of Tabs when on Button click. I'm calling the index like so, in android-tutorial.ts but it isn't working.
I am calling the function in android-tutorial.ts, with the function startApp();
Is there any other way to do this? What am I doing wrong?
Hope you can help me!

Ok I find a way to do it.
Here's how i solved it. I needed to be able to pass an Index to the tabs-page.ts from android-tutorial.ts
Here's the only thing I added:
constructor(public navCtrl: NavController, public events: Events, public alertCtrl: AlertController, public storageProvider: StorageProvider, public pushProvider: PushProvider, public aboutProvider: AboutProvider, private appVersion: AppVersion, public platform: Platform, public deviceProvider: DeviceProvider, public alertProvider: AlertProvider, public params: NavParams) {
this.mySelectedIndex = this.params.get('mySelectedIndex'); <---- THIS IS THE LINE I ADDED
this.platform.ready().then(() => {
this.getVersion();
//Navigate to Login Page on Startup
this.storageProvider.getUser().then((user: User) => {
if (user && user.token) {
let token = user.token;
this.events.publish("user:login", token);
this.pushProvider.start();
}
});
});
this.platform.resume.subscribe(() => {
this.getVersion();
});
this.events.subscribe("user:login", () => {
this.tabs[2].page = "AccountPage";
});
this.events.subscribe("user:logout", () => {
this.tabs[2].page = "LoginPage";
});
this.events.subscribe("user:notification", (data: any) => {
switch (data.additionalData.type) {
case "novelty":
this.events.publish("novelty:new");
this.navCtrl.push("NoveltyPage", {
id: data.additionalData.id
});
break;
// case "message":
// this.events.publish('message:new');
// this.navCtrl.push('MessagePage', {
// id: data.additionalData.id,
// });
// break;
default:
this.events.publish("card:update");
this.alertProvider.show(data.title, data.message);
break;
}
});
}
I am trying to overwrite the navigation back button to my needs in android using ionic 3 but whenever i run my app it shows an error when i press back navigation button saying "nav.getActive is not a function" due to this back button doesn't work.
Updated Code is as followed
export class MyApp {
rootPage:any = LoginPage;
public counter=0;
#ViewChild(Nav) nav: Nav;
constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen,public globalProvider: GlobalProvider,
public googlePlus: GooglePlus, public zone: NgZone, private readonly firebase: Firebase, private alertCtrl: AlertController,
public toastCtrl: ToastController, public app: App) {
platform.ready().then(() => {
// Okay, so the platform is ready and our plugins are available.
// Here you can do any higher level native things you might need.
statusBar.styleDefault();
splashScreen.hide();
platform.registerBackButtonAction(() => {
const activeView = this.nav.getActive().name // This will give you the activeview name
if(activeView === 'HomePage') {
if (this.nav.canGoBack()){ //Can we go back?
this.nav.pop();
} else {
const alert = this.alertCtrl.create({
title: 'App termination',
message: 'Do you want to close the app?',
buttons: [{
text: 'Cancel',
role: 'cancel',
handler: () => {
console.log('Application exit prevented!');
}
},{
text: 'Close App',
handler: () => {
platform.exitApp(); // Close this application
}
}]
});
alert.present();
}
}
this.nav.push(TabsPage);
}, 1);
this.firebase.onNotificationOpen().subscribe(notification => {
console.log('notification info: ', notification);
/*!notification.tap
? console.log('The user was using the app when the notification arrived...')
: console.log('The app was closed when the notification arrived...');
let notificationAlert = this.alertCtrl.create({
title: notification.title,
message: notification.body,
buttons: ['Ok']
});
notificationAlert.present();*/
},
error => {
console.error('Error getting the notification', error);
});
});
/*platform.registerBackButtonAction(() => {
if (this.counter == 0) {
this.counter++;
this.presentToast();
setTimeout(() => { this.counter = 0 }, 3000)
} else {
// console.log("exitapp");
platform.exitApp();
}
}, 0) });*/
}
Try like this.
#ViewChild(Nav) nav: Nav;
constructor(platform: Platform,
statusBar: StatusBar,

public globalProvider: GlobalProvider,
public toastCtrl: ToastController,
public googlePlus: GooglePlus,

platform.ready().then(() => {
// Okay, so the platform is ready and our plugins are available.
// Here you can do any higher level native things you might need.
statusBar.styleDefault();
splashScreen.hide();
platform.registerBackButtonAction(() => {
**const activeView = this.nav.getActive().name** // This will give you the activeview name
if(active.instance instanceof HomePage) {
if (nav.canGoBack()){ //Can we go back?
nav.pop();
} else {
const alert = this.alertCtrl.create({
title: 'App termination',
message: 'Do you want to close the app?',
buttons: [{
text: 'Cancel',
role: 'cancel',
handler: () => {
console.log('Application exit prevented!');
}
},{
text: 'Close App',
handler: () => {
platform.exitApp(); // Close this application
}
}]
});
alert.present();
}
}
nav.push(HomePage);
}, 100);
});
}
I am new to ionic development and I am facing some issue
We are consuming an API in the ionic3 app.

your

Try to put your try block in the call back of the present() function:
try {
etc...}
please Try with this
this.userService.loginUser(formData)
.then((res:any)=>{
//Success Code here
//Stop Loader
}).catch((err:any)=>{
//Error handling and Stop loader
})
Im using navigation control in ionic provider whenever i triggered the provider it shows the runtime error Cannot read property 'pop' of null
my code is
#Injectable()
export class ServerResponseProvider {
#ViewChild('myContent') navCtrl: NavController;
constructor(public http: Http, public alertCtrl: AlertController,
protected injector: Injector, private app:App) {
console.log('Hello ServerResponseProvider Provider');

.map(res => res.json())
.subscribe(data => {
console.log("response:", data);
observer.next(data);
}, (err) => {
console.log("Your error : ", err);
observer.error(err);
if (err.status == 400) {
this.alertC('Validation Error');
} else if (err.status == 403) {

How to go to a specific page when clicking on a notification?
I use Firebase console to push the notification
I used like this. but it didn't work
fcm.onNotification().subscribe(data=>{
if(data.wasTapped){
this.navcntrl.push(MessagePage);
};
})
How i can do it correctly?
My full code: app.component.ts
export class MyApp {
#ViewChild(Nav) nav: Nav;
rootPage: any = HomePage;
pages: Array<{title: string, component: any}>;
constructor(public platform: Platform,private fcm: FCM, public statusBar: StatusBar, public splashScreen: SplashScreen) {
fcm.onNotification().subscribe(data=>{
this.nav.push(ListPage)
})
this.initializeApp();
this.pages = [
{ title: 'Home', component: HomePage },
{ title: 'List', component: ListPage }
];
}
initializeApp() {
this.platform.ready().then(() => {
this.statusBar.styleDefault();
this.splashScreen.hide();
});
}
openPage(page) {
this.nav.setRoot(page.component);
}
}
Thanks in advance
I solve this issue.
You have to add the property “click_ action”: “FCM_PLUGIN_ACTIVITY” to the “notification” object in order to properly use the background method.
Example:
{
"to" : "tokenHere",
"notification" : {
"title": "title",
"body" : "message",
"sound": "default",
"click_action":"FCM_PLUGIN_ACTIVITY"
},
"data": {
"content": "whatever",
},
"priority":"high"
}
and use FCM API. Don’t use firebase console.
