Cordova pickcontact doesn't work

I try to pick a contact with cordova plugin contacts, but I still have a bug. My button #pickContact opens correctly the activity where I can tap on a contact. But when I tap on one, nothing happens. When I go back to my page, I have the error message OPERATION_CANCELLED_ERROR (code 6).
I really don't understand where is the problem. I run my app on Android Marshmallow. I thought about a permission problem, but my app can find correctly contacts with navigator.contacts.find, but not with navigator.contacts.pickContact
Here is my code :
function pickContact() {
navigator.contacts.pickContact(function(contact){
alert('ok !');
},function(err){
alert('bug !' + err);
console.log('Error: ' + err);
});
}
var app = {
// Application Constructor
initialize: function() {
this.onDeviceReady();
if (navigator.userAgent.match(/(iPhone|iPod|iPad|Android|BlackBerry)/)) {
document.addEventListener("deviceready", this.onDeviceReady, false);
} else {
this.onDeviceReady();
}
},
onDeviceReady: function() {
$("#pickContact").click(pickContact);
},
// Update DOM on a Received Event
receivedEvent: function(id) {
}
};
app.initialize();
Thanks for your help !

As per the reference doc of contacts plugin your selected contact will set into JSON.stringify(contact) you can alert it to see which contacts are selected (I have used this plugin but I don't need this function to pick any single contact so not sure if there is any done button or not) then press done or ok button, which will redirect you to your another function where you can get that contacts or fulfill your next requirements.
function pickContact() {
navigator.contacts.pickContact(function(contact){
alert(JSON.stringify(contact));
//This is added by me, on done button click or single selection
setContacts(contact);
},function(err){
alert('bug !' + err);
console.log('Error: ' + err);
});
}
//This is added by me
function setContacts(ct)
{
alert(JSON.stringify(ct));
$("#contactlist").append(ct);
//or
var getData = JSON.parse(ct);
if(getData.length > 1)
{
for(i=0;i<getData.length;i++)
{
$("#contactlist").append(getData[i]);
}
}
}
Let me know if I am wrong or right.

Thanks a lot for your answer. Unfortunately , your code doesn't works for me, but I found what to do :
When pickcontact opens your native app "contacts", your cordova app is removed on background. On android, that means that you loose the state of your app, and so you have a bug. To solve the problem, you need to add onresume event on your js file, like this :
var app = {
// Application Constructor
initialize: function() {
this.onDeviceReady();
if (navigator.userAgent.match(/(iPhone|iPod|iPad|Android|BlackBerry)/)) {
document.addEventListener("deviceready", this.onDeviceReady, false);
} else {
this.onDeviceReady();
}
},
onDeviceReady: function() {
$("#pickContact").click(pickContact);
},
onResume: function(resumeEvent) {
//alert('onResume');
},
// Update DOM on a Received Event
receivedEvent: function(id) {
}
};
app.initialize();
After that, you can retrieve your picked contact with a function like this :
function pickContact() {
navigator.contacts.pickContact(function(contact){
$("#divTest").append('<p>The following contact has been selected:' + JSON.stringify(contact));
},function(err){
alert('bug !' + err);
console.log('Error: ' + err);
});
}
So, like everytime in programming, when you know the answer, that's easy. But when you don't know, you loose hours and hours...
I hope that will help someone.

On Back button event Show confirm Yes,No option before closing app for window.open using Cordova InAppBrowser

Well i'm newbie & stuck at a point. And that might have simple solution as well..
I load a page using window.open using InAppBrowser, While user press hardware backbutton I want to show confirm message before app gets close. I tried some code...
Here is Code
index.html
$(document).ready(function() {
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
var ref = window.open('http://stackoverflow.com/', '_blank', 'location=no,hardwareback=yes');
ref.addEventListener('loadstart', function(event) { SpinnerPlugin.activityStart("Initializing..."); });
ref.addEventListener('loadstop', function(event) { SpinnerPlugin.activityStop(); });
ref.addEventListener('loaderror', function(event) { alert('error: ' + event.message); SpinnerPlugin.activityStop();});
ref.addEventListener('exit', function(event) {
alert('Exit')
});
ref.addEventListener("backbutton", function () { //But This is not triggering...Don't know why..
onConfirm();
})
function onConfirm(button) {
if (button == 1){ //Yes button pressed...
navigator.app.exitApp();
} else{
return false;
}
}
}
});
Even I tried backbutton event of Cordova..
document.addEventListener("backbutton", onBackKeyDown, false); //Listen to the User clicking on the back button
function onBackKeyDown(e) {
navigator.notification.confirm("Are you sure you want to exit ?", onConfirm, "Confirmation", "Yes,No");
}
It gets triggered properly but after closing inner window..
So again in brief, I want to show same confirm box before closing inner window.
Note: I'm using Cordova 6.1.0
Thanks a-ton in-Advance

I tried this , it ll work,
document.addEventListener("backbutton", function(e){
navigator.notification.confirm("Are you sure you want to exit the application?",fnLogout,"Warning","Ok,Cancel");
}, false);
function fnLogout(button) {
if(button == 1) {
navigator.app.exitApp();
} else {
return;
}
}
EDIT:
it’s highly possible that overriding the back-button for the InAppBrowser in PhoneGap is not possible.
Try to get brief details in below link:

Thanks.

ionic + cordova plugin and background mode

I'm making an app with ionic for car drivers. The app takes coordinates every one minute and write them on remote server, this helps me to tracking route and show cars on Google map.
I use Cordova plugin and it works fine except when screen turns off or the app goes into the background. I installed katzer cordova-plugin-background-mode, when the app go into background I see the message : app is now in background, the plugin informs me but nothing else, the app stopped! .
No data sent to remote server, when I resume the app all is back to normal, I use Android platform. How can i solve?
app.js code
angular.module('starter', ['ionic', 'ngCordova','LocalStorageModule', 'starter.controllers', 'starter.services'])
.run(function ($ionicPlatform) {
$ionicPlatform.ready(function () {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if (window.cordova && window.cordova.plugins && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if (window.StatusBar) {
// org.apache.cordova.statusbar required
StatusBar.styleLightContent();
}
cordova.plugins.backgroundMode.enable();
});
})
.....
controllers.js
angular.module('starter.controllers', [])
.controller('GeoCtrl', function($scope, $cordovaGeolocation, $cordovaNetwork, $http, $interval) {
var reloadCoordinates = function() {
var watchOptions = {
timeout : 10000,
enableHighAccuracy: false // may cause errors if true
};
var watch = $cordovaGeolocation.watchPosition(watchOptions);
watch.then(
null,
function(err) {
// error
},
function(position) {
//Latitudine e Longitudine
var lat = position.coords.latitude
var lon = position.coords.longitude
$scope.latitude = lat
$scope.longitude = lon
$http.post('http://192.168.1.2/get-data.php', { "lat": lat, "lon" : lon }).then(function(resp) {
console.log('Success Lat:'+resp.data.lat+' Lon:'+resp.data.lon);
watch.clearWatch();
}, function(err) {
console.error('ERR', err);
// err.status will contain the status code
})
});
};//end reloadCoordinates
$interval(reloadCoordinates, 60000);
reloadCoordinates();
})

I know this is an old thread, but I did manage to get this working, with:
cordova.plugins.backgroundMode.on('enable', function(){
//your code here, will execute when background tasks is enabled
loop();
});
function loop(){
console.log("loop");
$timeout(loop, 1000);
}
cordova.plugins.backgroundMode.enable();

#Cristian,
after enabling plugin, you should call your function or write your logic in this function.
cordova.plugins.backgroundMode.onactivate = function() {
// your logic here
// or call any other service, factory function
};

Are you trying to make an app that does something every x minutes, even when the app is in the background and/or the screen is turned off.... tried backgound-mode plugin but it only works reliably when the phone is plugged in... did you ever found a solution to this?
Install the plugin using the cordova command line utility:
$ cordova plugin add https://github.com/boltex/cordova-plugin-powermanagement.git
here's how i use it along with the background mode plugin so the app is never in background and always running as a service...:
if( ionic.Platform.isAndroid() ){
cordova.plugins.backgroundMode.enable();
window.powerManagement.dim(function() {
console.log('Wakelock acquired');
}, function() {
console.log('Failed to acquire wakelock');
});
window.powerManagement.setReleaseOnPause(false, function() {
console.log('setReleaseOnPause successfully');
}, function() {
console.log('Failed to set');
});
}
Final Step Deactivate your plugin when you finished your service as
cordova.plugins.backgroundMode.disable()

Ads not displaying with Admob PhoneGap Plugin

I have an Android application build with PhoneGap 3.4.
The plugin I am running is: https://github.com/floatinghotpot/cordova-plugin-admob.git
The installation instructions are:
A simplified method (tested on Cordova 3.4.0)
1. Install the Google Play Services plugin:
```cordova plugin add https://github.com/MobileChromeApps/google-play-services.git```
2. Install _this_ plugin:
```cordova plugin add https://github.com/floatinghotpot/cordova-plugin-admob.git```
The directions for displaying the Ads are:
##Using the Plugin:
There are 3 calls needed to get AdMob Ads:
1. `createBannerView`
Takes in a object containing a publisherId and adSize, as well as success
and failure callbacks. An example call is provided below:
window.plugins.AdMob.createBannerView(
{
'publisherId': 'INSERT_YOUR_PUBLISHER_ID_HERE',
'adSize': window.plugins.AdMob.AD_SIZE.BANNER
},
successCallback,
failureCallback
);
2. `requestAd`
Takes in an object containing an optional testing flag, and an optional
list of extras. This method should only be invoked once createBannerView
has invoked successCallback. An example call is provided below:
window.plugins.AdMob.requestAd(
{
'isTesting': false,
'extras': {
'color_bg': 'AAAAFF',
'color_bg_top': 'FFFFFF',
'color_border': 'FFFFFF',
'color_link': '000080',
'color_text': '808080',
'color_url': '008000'
},
},
successCallback,
failureCallback
);
3. `showAd`
Show or hide the Ad.
This method should only be invoked once createBannerView has invoked successCallback.
An example call is provided below:
window.plugins.AdMob.showAd(
true,
successCallback,
failureCallback
);
And here is my attempt:
function onLoad(){
document.addEventListener("deviceready", onDeviceReady, false);
}
function onDeviceReady() {
if(window.plugins && window.plugins.AdMob) {
var admob_android_key = 'ca-app-pub-xxxxxxxxxxxxxxxxxxxxxxx';
var adId = (navigator.userAgent.indexOf('Android') >=0) ? admob_android_key : admob_ios_key;
var am = window.plugins.Admob;
am.createBannerView(
{
'publisherId': adId,
'adSize': am.AD_SIZE.BANNER,
'bannerAtTop': false
},
function() {
am.requestAd(
{ 'isTesting':false },
function(){
am.showAd( true );
},
function(){ alert('failed to request ad'); }
);
},
function(){ alert('failed to create banner view'); }
);
} else {
alert('AdMob plugin not available/ready.');
}
}
Any idea where I am going wrong with this? Thank you in advance.

what you pasted is too complex
there are several to show ad right.
1.install ,just add this in your phonegap build config
<gap:plugin name="com.admob.plugin" version="1.0.0" source="plugins.cordova.io"/>
2.config admob
admob.showBannerAbsolute(admob.BannerSize.BANNER,0,70);
3.show admob ad when you want.
admob.showBanner(admob.BannerSize.BANNER,admob.Position.TOP_APP);
that is all.

Check if Cordova/Phonegap is correct

A simple question, how i can check if cordova is properly accessible and working in my html index file in android.
I tried searching for some syntax or code that can confirm but alas...
There are some functions that I am not able to access. Like navigator.connection.type gives me that type not defined of null..
So I am wondering if there is any way to check.
Thanks..
EDIT 1
$(document).one('pageinit', function(event) {
registerElementEvents();
validateFields();
// Check Internet Connection
checkConnection();
});
function checkConnection() {
//alert(window.top.navigator);
var objects = window.top.navigator;
for(var key in objects) {
var value = objects[key];
//alert(value);
}
if( !navigator.network )
{
// set the parent windows navigator network object to the child window
navigator.network = window.top.navigator.network;
}
// return the type of connection found
return ( (navigator.network.connection.type === "none" || navigator.network.connection.type === null ||
navigator.network.connection.type === "unknown" ) ? false : true );
}

There are lots of way to check
you can use the alert("your message"); so that you get a popup window in the function that
you want to work
Another way is using console.log("TESTING"); which will generate a log file. you can trace the log file too
for your nxt question regarding the connection type you can see and use this https://github.com/apache/cordova-plugin-network-information/blob/dev/doc/index.md

So reviewing the code it looks like the issue is that there is no check for the deviceready event.
Try something like this:
HTML:
<body onload="onLoad">
JS:
function onLoad() {
document.addEventListener('deviceready', deviceReady, false);
}
function deviceReady() {
registerElementEvents();
validateFields();
// Check Internet Connection
checkConnection();
}

I make use of a boolean value. When it is true, PhoneGap is propperly loaded.
// device ready
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
window.deviceReady = true;
}
