问题
I am using javascript to check if app is installed or not, if my app installed i want to open my app or else it will redirect to play store account. the issue is that it is redirecting to play store even i already have app installed
This is my .html file where i am checking for app
<!DOCTYPE html>
<html>
<body>
<script type="text/javascript">
window.onload = function() {
// Deep link to your app goes here
document.getElementById("l").src = "intent://sdf/SplashScreen#Intent;scheme=vsd;package=com.sdf.android.ff;end";
setTimeout(function() {
// Link to the App Store should go here -- only fires if deep link fails
window.location = "https://play.google.com/store/apps/details?id=com.sdf.android.dffd";
}, 500);
};
</script>
<iframe id="l" width="1" height="1" style="visibility:hidden"></iframe>
</body>
</html>

It solved by this way
<html>
<head>
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script>
var fallbackToStore = function() {
window.location.replace('https://play.google.com/store/apps/details?id=packgename');
};
var openApp = function() {
window.location.replace('intent://app/SplashScreen#Intent;scheme=app_;package=com.sdf.android.dsds;end');
};
var triggerAppOpen = function() {
openApp();
setTimeout(fallbackToStore, 700);
};
triggerAppOpen();
</script>
