AdMob在KIVY-Java上奖励了视频广告.安卓

问题描述：

我正在尝试在第一款游戏中显示Google admob奖励的视频，但似乎无法正常运行.到目前为止，这是我所拥有的，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.

I'm trying to display google admob rewarded videos on my first game but I can't seem to make it work. This is what I have so far, I don't know Java so this is a very difficult for me. Any help will be appreciated, I'm willing to learn.

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

这使用此作为指南.

编辑**:标语测试有效，但我需要的是仍无法正常工作的奖励广告.我main.py中的第59行也是:ad_inst = Admob()

EDIT**: The banner test works but what I need is the rewarded ads which still does not work. Also line 59 in my main.py is: ad_inst = Admob()

您正在考虑正确的方向，但要使其正常工作，您需要RewardedVideoAdListener.您可以使用 PythonJavaClass 和 java方法:

You're thinking in right direction but to make it work you need RewardedVideoAdListener. You can create it using PythonJavaClass and java methods from PyJnius like that:

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，您可以向此方法添加一些处理程序，例如:

Of course, you can add some handlers to this methods, for example:

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()))

并且您必须在setRewardedVideoAdListener方法中使用此侦听器:

And you have to use this listener in your setRewardedVideoAdListener method:

mRewardedVideoAdListener = RewardedVideoAdListener()
mRewardedVideoAd.setRewardedVideoAdListener(mRewardedVideoAdListener)
