During the development of my Android application using Cordova and Ionic framework, I encountered an issue with the network plugin from this source (https://github.com/apache/cordova-plugin-network-information). After the device ready alert triggers, I received the following error message:
"TypeError: Cannot read property 'type' of undefined
Below is the navigator object that caused the error:
navigator.connection.type
The error was pinpointed to the specific line mentioned above.
utilize mine
document.addEventListener("deviceready", onDeviceReady, false);
// Cordova is prepared
function onDeviceReady() {
checkNetwork()
}
function checkNetwork() {
networkStatus = navigator.connection.type;
var options = {};
options[Connection.UNKNOWN] = 'Unknown connection';
options[Connection.ETHERNET] = 'Ethernet connection';
options[Connection.WIFI] = 'WiFi connection';
options[Connection.CELL_2G] = 'Cell 2G connection';
options[Connection.CELL_3G] = 'Cell 3G connection';
options[Connection.CELL_4G] = 'Cell 4G connection';
options[Connection.CELL] = 'Cell generic connection';
options[Connection.NONE] = 'No network connection';
alert('Connection type: ' + options[networkStatus]);
}
It appears that the navigator.connection object is not initialized simultaneously with cordova.
To work around this issue, you can implement a timeout function specifically tailored for Angular/Ionic like the one below:
setTimeout(function(){
var connection = connectionService.getConnection();
console.log("connection : "+connection);
$scope.connection = connection;
$scope.$apply()
}, 5000)
