AppLovinSDKを android java(ネイティブ)で導入する方法

Unityやcocos2dxとは違い、androidのライフサイクルが絡んでくるので、
個人的にはネイティブで導入する方が難しかった。
複数の動画SDKを入れる場合は、メディエーションで入れるととコールバックがまとめられ楽できるかもw。汗

getActivityやgetApplicationContext等をシングルトンとして引き回したい場合の参考にも。ｗ汗

インスタースティシャル版の導入

Android Studio等でツール・アプリを作る際は、、
初期化後、getApplicationContext()や、getAcitivy()の情報を引き回す必要があり、
それらに注意する。

WeakReferenceというものをキャッシュされたののを引き回す事ができるので、
予め、getApplicationContext()とgetActivity()をできるようにしておくと便利

例：

// MainActivityでセットした参照をキャッシュを使って、applovin再生
final WeakReference<MainActivity> weakRef = new WeakReference<MainActivity>(MainActivity.getInstance());

getApplicationContext()を引きまわす準備

シングルトンの準備

MyApplication.java

public class MyApplication extends Application {

    //シングルトンの代わりとして利用（アプリが終了するまで存在する
    private static MyApplication sInstance; 

    // 取得用
    public static MyApplication getInstance() {
        return sInstance;
    }

    @Override
    public void onCreate() {
        super.onCreate();


        sInstance = this;

呼び出し側

MyApplication.getInstance();

これで、AppCompatAcitivy等、Acitivyも持っている場合はこれだけでOK。

getAcitivy()を引き回す

Fragment等で、Acitivyが呼び出したい画面でActivityが取得できない場合は、
FragmentAcitivyを継承しているところで、Singleton化してあげる必要があります。

MainAcitivy.java

public class MainActivity extends FragmentActivity {

    private static MainActivity mainActivityInstance; //シングルトンの代わりとして利用（アプリが終了するまで存在する

    // 取得用
    public static MainActivity getInstance() {
        return mainActivityInstance;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mainActivityInstance = this;

呼び出し側

MainActivity.getInstance()

AppLovin動画再生

HogeFrament.java

    private AppLovinIncentivizedInterstitial incentivizedInterstitial;


 //〜〜省略〜〜


    final WeakReference<MainActivity> weakRef = new WeakReference<MainActivity>(MainActivity.getInstance()); // ★先程のMainActivityで用意したインスタンスを使用




 //〜〜省略〜〜


    // Applovin リワード型の読み込み準備
    incentivizedInterstitial = AppLovinIncentivizedInterstitial.create(MyApplication.getInstance()); //先程用意した、MyApplicationのインスタンスを使って、applovinを初期化
    incentivizedInterstitial.preload(new AppLovinAdLoadListener() {
        @Override
        public void adReceived(AppLovinAd appLovinAd) {
            // showButton.setEnabled(true); //動画視聴ボタンを有効化等
        }


        @Override
        public void failedToReceiveAd(int errorCode) {
            log("Rewarded video failed to load with error code " + errorCode);
        }
    });

//〜〜省略〜〜

    // Applivn リワード型再生可能かチェック
    if (incentivizedInterstitial.isAdReadyToDisplay()) {

        // Applovin コールバック
        // Reward Listener
        AppLovinAdRewardListener adRewardListener = new AppLovinAdRewardListener() {
            @Override
            public void userRewardVerified(AppLovinAd appLovinAd, Map map) {
                // AppLovin servers validated the reward. Refresh user balance from your server.  We will also pass the number of coins
                // awarded and the name of the currency.  However, ideally, you should verify this with your server before granting it.

                // i.e. - "Coins", "Gold", whatever you set in the dashboard.
                String currencyName = (String) map.get("currency");

初期化は起動時にやっておくと、バッファリング時間の省略になると思うので、起動時にやっておいた方がいいと思います。
