I am trying to check whether the Native app is installed or not , If it is not I have to prompt the user to download it from the webpage. For chrome I used to achieve by checking the error messages from runtime.LastError. However in case of Firefox it gives error only in console No such native application extension_name and not catching it in the runtime.LastError method.
Is there any way that we can identify whether corresponding Native app is installed or not ? I am facing issue when Native app is not installed and browser.runtime.lastError is not giving any error.
Can you please suggest if there is any way in Firefox Webextension that we can catch such errors and identify it in code whether the corresponding Native app is installed or not on the user machine.
It will really helpful if someone can provide some info on this.
for e.g. :
startNativeApp: function(force){
// note that when the native app is opened and ready, it will call "_ABC_onAgentReady"
ABC.log('Starting native app.');
if (!ABC.appConnected) {
try {
ABC.nativeAppPort = browser.runtime.connectNative(_ABC_native_app_id);
ABC.nativeAppPort.onMessage.addListener(ABC.onNativeMessageReceived);
ABC.nativeAppPort.onDisconnect.addListener(ABC.onNativeAppDisconnected);
ABC.appInstalled = true;
ABC.appConnected = true;
} catch(e) {
ABC.log('Error starting native app: ' + e.message, 'ERR');
}
} else if (force === true) {
ABC.log('Native app is already running; attempting to stop and will restart in 750ms.');
ABC.stopNativeApp();
setTimeout(function() { ABC.startNativeApp(true); }, 750);
}
},
onNativeAppDisconnected: function(message) {
console.log("ABC LastError : "+browser.runtime.lastError);
console.log("ABC LastError : "+ABC.nativeAppPort.error);
console.log("ABC LastError : "+JSON.stringify(message));
ABC.appConnected = false;
ABC.nativeAppPort = null;
ABC.appInstalled = false;
if (browser.runtime.lastError && (browser.runtime.lastError.message.indexOf("No such native application") !== -1 )) {
ABC.appInstalled = false;
}
// cleanup: reset the sig data so that it is re-requested on the next scan
_ABC_sa_data = "";
_ABC_sigs = "";
if (browser.storage && browser.storage.local) {
browser.storage.local.set({ uid: _ABC_be_uid }, null);
}
ABC.log('Send message to page to stop.');
ABC.sendMessageToPage({ onNativeAppDisconnected: '' });
ABC.log('Native app disconnected.');
},
