我对此做了很多研究，但我没有得到任何解决方案。任何帮助都将得到赞赏

我实施的代码是：

private RewardedVideoAd mRewardedVideoAd;

MobileAds.initialize(activity, getString(R.string.admob_app_id));

            mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(activity);
            mRewardedVideoAd.setRewardedVideoAdListener(this);
            loadRewardedVideoAd();


private void loadRewardedVideoAd() {
        synchronized (mLock) {
            if (!mIsRewardedVideoLoading && !mRewardedVideoAd.isLoaded()) {
                mIsRewardedVideoLoading = true;
                Bundle extras = new Bundle();
                extras.putBoolean("_noRefresh", true);
                AdRequest adRequest = new AdRequest.Builder()
                        .addNetworkExtrasBundle(AdMobAdapter.class, extras)
                        .build();
                mRewardedVideoAd.loadAd(getString(R.string.random_video), adRequest);
            }
        }
    }

    private void showRewardedVideo() {
        if (mRewardedVideoAd.isLoaded()) {
            randomClicked = -1;
            mRewardedVideoAd.show();
        }
    }

@Override
    public void onRewardedVideoAdLoaded() {
        mIsRewardedVideoLoading = false;
    }

    @Override
    public void onRewardedVideoAdOpened() {

    }

    @Override
    public void onRewardedVideoStarted() {

    }

    @Override
    public void onRewardedVideoAdClosed() {
        loadRewardedVideoAd();
    }

    @Override
    public void onRewarded(RewardItem rewardItem) {

    }

    @Override
    public void onRewardedVideoAdLeftApplication() {

    }

    @Override
    public void onRewardedVideoAdFailedToLoad(int i) {
        mIsRewardedVideoLoading = false;
        Log.i("rewarded_video", "Failed to Load Rewarded Video " + i);
        loadRewardedVideoAd();
    }

Answer 1

首先，将其添加到清单文件

 <activity android:name="com.chartboost.sdk.CBImpressionActivity"
        android:excludeFromRecents="true"
        android:hardwareAccelerated="true"
        android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen"
        android:configChanges="keyboardHidden|orientation|screenSize" />

另外，不要忘记向Manifest文件添加必要的权限。

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

最后，如果您刚刚创建了帐户，或者刚刚对其进行了一些更改，则可能需要等待一段时间才能使更改生效，然后才能看到广告。
