Does anybody know how can I recognize when is the app first launched? I need to show message dialog only at the first start after install. Thanks...
You can use IsolatedStorageSettings and check for a flag.
var settings = IsolatedStorageSettings.ApplicationSettings;
if (!settings.Contains("WasLaunched")) {
MessageBox.Show("First time to launch");
settings.Add("WasLaunched", true);
}
Note that re-deploying your app will reset the flag since its just a file saved in Isolated Storage but this should work if you launch your app from within emulator/actual device.

I am implementing an appium test on remote android driver, with chrome browser for loading urls.
Some of the Urls are pdfs, and chrome asks to store those files. and appears that chrome doesnt have access to filesystem to store those files, which results in a dialog like below.
Please help me pass that dialog without any manual inputs.
Upon clicking continue, it will load actual permissions dialog from Android.
Here is my code initialize appium capabilities
DesiredCapabilities caps = DesiredCapabilities.android();
caps.setCapability("appiumVersion", "1.9.1");
caps.setCapability("deviceName","Samsung Galaxy S9 Plus HD GoogleAPI Emulator");
caps.setCapability("deviceOrientation", "portrait");
caps.setCapability("browserName", "Chrome");
caps.setCapability("platformVersion", "8.1");
caps.setCapability("platformName","Android");
caps.setCapability("autoAcceptAlerts", true);
caps.setCapability("autoGrantPermissions", true);
caps.setCapability("chromedriverArgs", "--allow-file-access-from-files");
caps.setCapability("maxDuration", 10000);
and this is the snippet I use to load a Url
driver.navigate().to("http://kmmc.in/wp-content/uploads/2014/01/lesson2.pdf");
autoGrantPermission also doesnt work in this case because chrome is already installed. Appium team has already rejected this issue -

Please help!
Indeed I had very hard time finding out the solution, but eventually I found a workaround.
The best workaround would have been reinstalling the chrome package. I tried that, but I could not start chrome after reinstalling it, as I had no access to shell, and chromedriver complained. So I left that track.
I tried getting hold of adb command or mobile:changePermissions but for that you need to use server flag --relaxed-security while starting the server, and saucelabs doesnt provide any handy interface to start the server with this flag.
The last resort, I found a solution here - https://stackoverflow.com/a/51241899/4675277 . But just that was not sufficient, because it helped me fix chrome alert, but later on it popped up with another alert with allow and deny, for which another solution in the same question helped me. So this is the code I eventually used -
driver.navigate().to("http://kmmc.in/wp-content/uploads/2014/01/lesson2.pdf");
String webContext = ((AndroidDriver)driver).getContext();
Set<String> contexts = ((AndroidDriver)driver).getContextHandles();
for (String context: contexts){
if (context.contains("NATIVE_APP")){
((AndroidDriver)driver).context(context);
break;
}
}
driver.findElement(By.id("android:id/button1")).click();
contexts = ((AndroidDriver)driver).getContextHandles();
for (String context: contexts){
if (context.contains("NATIVE_APP")){
((AndroidDriver)driver).context(context);
break;
}
}
driver.findElement(By.id("com.android.packageinstaller:id/permission_allow_button")).click();
((AndroidDriver)driver).context(webContext);
This helps allow all permissions required.
I am new to chrome extensions.I used chrome.runtime.onInstalled to load a html page whenever the extension is installed or updated.But when i am testing it in chrome, whenever i check/uncheck Allow in incognito the same html page loads each time.How to avoid this behaviour? I used "incognito":"split" in manifest.
I wish you'd posted the code so I could try to replicate the problem and give a specific solution but the easy solution is to use chrome storage API to save the extension's version when welcome.html is opened and compare it to the current version next time onInstalled is fired.
If the stored version is the same don't open it. If it's undefined or older, open it.
Get your extension's version by extracting it from chrome.extension.getURL("manifest.json")
Edit:
After a bit of googling it seems you can access the manifest more directly. Get the version number using the code below.
var version = chrome.runtime.getManifest().version;
Edit:
It seems the previous version is supplied in the callback when you update so you don't need to store anything. The object provided can be compared to the current version using chrome.runtime.getManifest().version
Something like this:
chrome.runtime.onInstalled.addListener(function (details) {
if(details.reason === "install"){
chrome.tabs.create({url: "welcome.html"});
}
else if(details.reason === "update"){
var currentVersion = chrome.runtime.getManifest().version;
var previousVersion = details.previousVersion;
if(previousVersion !== currentVersion){
chrome.tabs.create({url: "welcome.html"});
}
}
});
I don't think you can. I assume that when you uncheck "Allow in incognito", Chrome nukes the local state of the (split) incognito instance.
in my windows phone 8 application i am using custom uri association to launch another application through my phone.
i.e
await Windows.System.Launcher.LaunchUriAsync(new Uri("sixtag:"));
but my app is not able to get certified for store because of this. the testing team tells that you app terminates unexpectedly while executing this.
now, i don't know how to deal with this.
is there any way to throw exception if the app which i am launching is not installed on phone ?
or i should try something else so my task gets accomplished and app gets certified for store as well.
You do not need to wrap your launch in try/catch or check for success as described in the other answers. As soon as you call LaunchUriAsync, the platform takes over and will automatically handle the possibility of no app being installed by asking the user if she wishes to search in the store.
A couple of things to double-check:
1) Ensure that you can successfully back into your app following the navigation to sixtag.
2) Ensure that your call to LaunchUriAsync is the direct result of a user action (eg. tapping a button)
try
{
await Windows.System.Launcher.LaunchUriAsync(new Uri("sixtag:"));
}
catch
{
MessageBox.Show("please install Sixtag from the app store","AppMissing", MessageBoxButton.OK);
}
you can perhaps display another button and on clicking directly navigate to the app store. See if this solves your problem. Do vote it up if it does :)
You are needed to handle that as shown here . Also Read out Remarks given there.
I am trying to write a chrome.app that is able to open and close chrome.app windows on both displays of a system that is configured with two monitors. When launched, the chrome application establishes a socket connection with a native application running on the same computer, I also open a hidden window via chrome.app.window.create to keep the chrome application up and running. The native application then reads a configuration file and then sends a series of ‘openBrowser’ commands to the chrome application via the socket.
When the chrome application receives an ‘openBrowser’ command, the chrome application makes a call to the chrome API method chrome.app.window.create, passing the create parameters AND a callback function. A code snippet is below:
NPMBrowserManager.prototype.openBrowser = function (browserId,htmlFile,browserBounds,hidden,grabFocus)
{
var browserManager = this;
var createParameters = {};
createParameters.bounds = browserBounds;
createParameters.hidden = hidden;
chrome.app.window.create(htmlFile,createParameters,function(appWindow)
{
// Check to see if I got a non-undefined appWindow.
if(appWindow !== null)
{
browserManager.browsers.push({"browserId":browserId,"window":appWindow});
console.info("NPMBrowserManager.openBrowser: Added browser, id =" + browserId + ", count =" + browserManager.browsers.length);
}
});
}
Unfortunately, the ‘appWindow’, parameter passed in the create callback is always undefined. I suspect it has something to do with the fact that the method openBrowser is itself being called by another method that processes commands received from the native application. However, the window opens exactly here and when I want to to, I just can’t seem to cache away any information about the new window that can be used later to close or move the window.
I want to be able to cache away the appWindow so that I can close or modify the created window later on in the workflow.
As a side note, I’ve noticed that appWindow is NOT undefined if I call the openBrowser method from within the callback that is associated with the chrome.app.runtime.onLaunched event. I suspect it has something to do with the current script context. I was not able to find any chrome.app documentation that goes into any detail about the chrome app architecture.
I would GREATLY appreciate it if anyone out there can explain to me how I can get the appWindow of the window that is created in the chrome.app.window.create method. By the way, I have also tried calling chrome.app.window.current to no avail… Very frustrating!!!
I’d also be interested in any documentation that might exist. I am aware of developer.chrome.com, but could not find much documentation other than reference documentation.
Thanks for the help!

Is there a Chrome extension post install hook/API function that will let me perform an action after the plugin is installed or updated?
I would like to perform an action after my extension is installed, and only right after it is installed. This action should only be performed once (post-install or post-update) of the extension.
Update
Some people have proposed setting the version of the extension in localStorage, the problem that I have is that the content script that has access to localStorage is not loaded into the page when the plugin is first installed.
AFAIK after a plugin is installed, and it makes use of a content script injected into the tab/page, the page has to be reloaded.
I don't know how to access localStorage from the background page; localStorage can only be accessed from a content script.
To get the version number from the background page to the content script requires the use of chrome API function to execute scripts:
chrome.tabs.executeScript(null, {code:function_to_execute}, function() { // callback });
However, when you install a plugin, and the page that this plugin needs to inject a content script into is already loaded, it does not inject the content script, you have to reload the page.
update 2
Looking at some of the tips provided in more detail, for the purpose of saving the version number, it is possible to access the localStorage of the background page. However, for what I need to do, which is reload a specific tab at a specific URL (in order to make sure the content script is the newest version) after installing or updating a plugin, it ended up being unnecessary to bother with localStorage.
For the sake of staying on topic, the advice given about writing the version number to localStorage (in the background page) and then checking against the version number in the manifest file is good enough to allow someone to run a script the first time it is installed/or updated.
HowTo
Make manifest file available to the background page (note: this is taken from somewhere else, I don't take credit for it, but I can't remember the source, if you know, let me know and I will add it).
// MAKE MANIFEST FILE AVAILABLE
chrome.manifest = (function() {
var manifestObject = false;
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
if (xhr.readyState == 4) {
manifestObject = JSON.parse(xhr.responseText);
}
};
xhr.open("GET", chrome.extension.getURL('/manifest.json'), false);
try {
xhr.send();
} catch(e) {
console.log('Couldn\'t load manifest.json');
}
return manifestObject;
})();
Now you can access your version number like this: chrome.manifest.version
To write to localStorage just pass it in like so: localStorage['my_plugin_version'] = chrome.manifest.version
You can do this using a background page. When the extension is installed, the background page is opened in the background, and thus executed. To make sure it's not executed every time, simply store a value in localStorage.
