How To Use / Implement This Project

Step 1. Add the JitPack repository to your build file

<Option 1> Groovy Gradle

// Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

<Option 2> Kotlin DSL Gradle`

// Add it in your root build.gradle.kts at the end of repositories:

allprojects {
    repositories {
        ...
        maven("https://jitpack.io")
    }
}

Step 2. Add the dependency

<Option 1> Groovy

dependencies {
    // library google admob (Required)
    implementation 'com.google.android.gms:play-services-ads:${admob_version}'

    // library unity ads (Required)
    implementation 'com.unity3d.ads:unity-ads:${unity_ad_version}'

    // library frogo-admob (Required - Recomended)
    implementation 'com.github.amirisback:frogo-admob:5.3.7'

    // -----------------------------------------------------------------------------------------
    // For Single Library Patch 

    // library frogo-admob (Admob Only)
    implementation 'com.github.amirisback.frogo-admob:ad-admob:5.3.7'

    // library frogo-admob (Unity Ads Only)
    implementation 'com.github.amirisback.frogo-admob:ad-unityad:5.3.7'
}

<Option 2> Kotlin DSL

dependencies {
    // library google admob (Required)
    implementation("com.google.android.gms:play-services-ads:${admob_version}")

    // library unity ads (Required)
    implementation("com.unity3d.ads:unity-ads:${unity_ad_version}")

    // library frogo-admob (Required - Recomended)
    implementation("com.github.amirisback:frogo-admob:5.3.7")

    // -----------------------------------------------------------------------------------------
    // For Single Library Patch

    // library frogo-admob (Admob Only)
    implementation("com.github.amirisback.frogo-admob:ad-admob:5.3.7")

    // library frogo-admob (Unity Ads Only)
    implementation("com.github.amirisback.frogo-admob:ad-unityad:5.3.7")

}

Step 3. Adding meta-data on AndroidManifest.xml

<manifest>
    <application>
        <!-- Sample AdMob App ID: ca-app-pub-3940256099942544~3347511713 -->
        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"/>
    </application>
</manifest>

frogo-admob's Issues

ad listeners

Hi, how can I use ad listeners(ad close listener) especially for rewarded ads. If I use After OnUserEarnedReward to intent other activity rewarded ad stays on in the background. It can be a problem for both users and advertising policy.

App Crash

Run this project,but crashed.

Android 12 Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.

java.lang.IllegalArgumentException: com.frogobox.appadmob: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

Rewarded & Rewarded Interstitial ID Same

Does it support native ads ?

Like ads in article and not floating to top or bottom

Hope to increase the failure callback

setupShowAdsRewardedInterstitial(object : IFrogoAdmob.UserEarned { override fun onUserEarnedReward(rewardItem: RewardItem) { // TODO User Get Reward } })

error : No ad config

i do not change anything and i try to use test (demo). but show error.

Error - Run - IFrogoAdRewarded [callback] : onAdFailedToLoad()

saving activity context is bad practice?

Hi there
I see that you save the activity context in the admob class and then use it to show interstitial ads.
isn't it a bad practice to save the activity context as a member variable?
wouldn't it be better practice to pass the activity context only when we want to show an interstitial ad?
