Android AppFlood类型中的showFullScreen（Activity）方法不适用于参数（new Handler（）{}}error）

我尝试实现appflood广告并出现错误。我真的不知道为什么会出现此错误：

The method showFullScreen(Activity) in the type AppFlood is not applicable for the arguments (new Handler(){} .

我的主要活动：

protected Handler handler = new Handler() {

        @Override
        public void handleMessage(Message msg) {
            switch (msg.what) {
            case SHOW_ADS: {

                // Display the AppFlood Ad
                AppFlood.showFullScreen(this);
                Gdx.app.log("Show Ads", "");

                break;
            }

            case LOAD_ADS: {

我也会在清单中得到错误。错误是元素类型meta-dataandroid:name后面必须跟属性规范，>或/>。但我有它

这是我的舱单：

<activity
android:name="com.appflood.AFSplashScreenActivity"
android:configChanges="keyboardHidden|orientation"
android:theme="@android:style/Theme.Translucent" >
</activity>
<activity
android:name="com.appflood.mraid.MraidBrowserActivity"
android:configChanges="keyboardHidden"
android:launchMode="singleTask"
android:theme="@android:style/Theme.Translucent" >
</activity>
<activity
android:name="com.appflood.AFFullScreenActivity"
android:configChanges="keyboardHidden|orientation"
android:theme="@android:style/Theme.Translucent"
android:launchMode="singleTask">
</activity>
<receiver
android:name="com.appflood.AFReferralReceiver"
android:exported="true" >
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>
<meta-data
    android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version"

 />

用YourActivit替换此。thisNow应用程序已停止工作。但它解决了错误。
