implementing Google Admob SDK severely impacts app startup time

[Rik Van velzen]

Does anyone have any idea why the implementation of the admob sdk severly impacts my app startup time.

Anyone had any troubles with this as well?

Whether I use the stand alone or the firebase related sdk my app startup time now changes from a normal and good start up time to an average of 10 or more seconds.

I would like to implement it, but it just seems unworkable for now.

Any hints/tips greatly appreciated.

btw. I have implemented version 18.2.0

It's a known issue. There are some workarounds:

• https://groups.google.com/d/topic/google-admob-ads-sdk/NBpj7fy7wYc/discussion  -- "MobileAds.initialize(context, id); takes too long"
• https://groups.google.com/d/topic/google-admob-ads-sdk/QFEoEJUbXjk/discussion -- "MobileAds.initialize causes much more ANRs."
• https://groups.google.com/d/topic/google-admob-ads-sdk/W-NWXxc1m4o/discussion  -- "Admob SDK is extremely slow and blocking the UI thread"
• https://groups.google.com/d/topic/google-admob-ads-sdk/rpyMso65TCs/discussion  -- "AdWorker thread monopolises CPU on some devices"
• https://groups.google.com/d/topic/google-admob-ads-sdk/Hi6AQVhwfE8/discussion  -- "AdMob initialize delay and error."

Also consider trying an older version of the AdMob SDK, which may perform slightly quicker. You can find older version numbers here: https://maven.google.com --> search for "play-services-ads" or "firebase-ads" and click to expand the sub-lists.

Hi there,

Thank you for reaching out to us. 

With regard to your concern, this is a normal behavior of the SDK as it utilize the WebView which, impacts startup time of some devices. 

One of the solutions provided by our Engineering team is to include this code into your app (also provided by inibehe@ on this same thread), and to call it on app startup before invoking the SDK. Could you compare how long the SDK takes to init?

private void initWebView() {
    long beforeWebViewInit = System.currentTimeMillis();
    WebView webView = new WebView(this);
    webView.loadUrl("https://www.google.com");
    long afterWebViewInit = System.currentTimeMillis();
    Log.d("MyApp", "WebView init diff: " + (afterWebViewInit - beforeWebViewInit));
  }
