KIVY - Java 上的 Admob 奖励视频广告。安卓

Question

我正在尝试在我的第一个游戏中显示 google admob 奖励视频，但我似乎无法让它发挥作用。这是我到目前为止所拥有的，我不了解 Java，所以这对我来说非常困难。任何帮助将不胜感激，我愿意学习。

RewardedVideoAd = autoclass('com.google.android.gms.ads.reward.RewardedVideoAd')
RewardedAds = autoclass('com.google.android.gms.ads.MobileAds')  

class AdmobAndroid(EventDispatcher):
    mRewardedVideoAd = ObjectProperty(None)
    mRewardedAds = ObjectProperty(None)

    def __init__(self,**kwargs):
        super(AdmobAndroid,self).__init__(**kwargs)

        self.mRewardedVideoAd = RewardedVideoAd(mactivity)
        self.mRewardedAds = RewardedAds(mactivity)
        self.mRewardedVideoAd = self.mRewardedAds.getRewardedVideoAdInstance()
        self.mRewardedVideoAd.setRewardedVideoAdListener()
        self.mRewardedVideoAd.setAdUnitId(settings.REWARDED_UNIT_ID)


    @run_on_ui_thread
    def request_Rewarded(self):
        if not self.mRewardedVideoAd.isLoaded():
            log('REQUESTING rewarded AD')
            adRequestBuilder = AdRequestBuilder()
            adRequest = adRequestBuilder.build()
            self.mRewardedVideoAd.loadAd(adRequest)
        else:
            log('NO NEED TO REQUEST rewarded AD,already loaded...')

    @run_on_ui_thread
    def show_Rewarded(self):
        if self.mRewardedVideoAd.isLoaded():
            self.mRewardedVideoAd.show()
            return True
        return False

这里以this 为指导。

编辑**：横幅测试有效，但我需要的是仍然无效的奖励广告。我的 main.py 中的第 59 行也是：ad_inst = Admob()

您的想法是正确的，但要使其发挥作用，您需要 RewardedVideoAdListener。您可以使用 PyJnius 中的 PythonJavaClass 和 java methods 来创建它：

from jnius import PythonJavaClass, java_method

from kivy.logger import Logger

from functools import partial

class RewardedVideoAdListener(PythonJavaClass):

    __javacontext__ = 'app'
    __javainterfaces__ = ["com.google.android.gms.ads.reward.RewardedVideoAdListener"]

    __INFO = True

    @java_method('()V')
    def onRewardedVideoAdLeftApplication(self):
        if self.__INFO:
            Logger.info("AdMob: onRewardedVideoAdLeftApplication")

    @java_method('()V')
    def onRewardedVideoAdClosed(self):
        if self.__INFO:
            Logger.info("AdMob: onRewardedVideoAdClosed")

    @java_method('(I)V')
    def onRewardedVideoAdFailedToLoad(self, errorCode):
        if self.__INFO:
            Logger.info("AdMob: onRewardedVideoAdFailedToLoad, errorCode is "+str(errorCode))

    @java_method('()V')
    def onRewardedVideoAdLoaded(self):
        if self.__INFO:
            Logger.info("AdMob: onRewardedVideoAdLoaded")

    @java_method('()V')
    def onRewardedVideoAdOpened(self):
        if self.__INFO:
            Logger.info("AdMob: onRewardedVideoAdOpened")

    @java_method('(Lcom/google/android/gms/ads/reward/RewardItem;)V')
    def onRewarded(self, reward):
        if self.__INFO:
            Logger.info("AdMob: onRewarded, type is "+str(reward.getType())+", amount is "+str(reward.getAmount()))

    @java_method('()V')
    def onRewardedVideoStarted(self):
        if self.__INFO:
            Logger.info("AdMob: onRewardedVideoStarted")

当然，你可以在这个方法中添加一些处理程序，例如：

from kivy.clock import Clock
from functools import partial

@java_method('(Lcom/google/android/gms/ads/reward/RewardItem;)V')
def onRewarded(self, reward):
    if self.__INFO:
        Logger.info("AdMob: onRewarded, type is "+str(reward.getType())+", amount is "+str(reward.getAmount()))
    self.__rewarded = True
    Clock.schedule_once(partial(on_reward, reward.getType(), reward.getAmount()))

而且你必须在你的 setRewardedVideoAdListener 方法中使用这个监听器：

mRewardedVideoAdListener = RewardedVideoAdListener()
mRewardedVideoAd.setRewardedVideoAdListener(mRewardedVideoAdListener)
