admob ads are not shown with pro guard

Question

I developed android app and I used admob sdk 6.2.1 for showing ads, and when I tested the app on my real device and on the emulator,ads are shown. but when I apply pro guard to my app and test it on my device(I tested it on another devices also) ads are not shown up, any help please!

Answer 1

Add this to your proguard:

-keep class com.google.ads.** # Don't proguard AdMob classes
-dontwarn com.google.ads.** # Temporary workaround for v6.2.1. It gives a warning that you can ignore

EDIT 2020:

For some time now, the Google Mobile Ads SDK has distributed its own proguard rules that get manifest merged into your app, so you don't need to add anything yourselves. The merged rules also keep around methods from third-party mediation adapters that are needed to make mediation work.

Answer 2

From the docs:

To safely use ProGuard with Google Mobile Ads, add the following to your ProGuard config:

-keep public class com.google.android.gms.ads.** {
    public *;
}

-keep public class com.google.ads.** {
    public *;
}

This will prevent all public methods on public classes from being obfuscated.

If you use AdMob Mediation with other ad networks, you should keep public methods from public classes for each SDK and adapter library as well.
