我是Android新视频广告的新手。我试图创建一个带有奖励视频广告的应用,如Rewarded Ads: Publishers Get Started
中所述应用程序中有一个按钮,允许用户查看激励的视频。视频加载后启用该按钮。
我第一次打开应用程序时一切正常。我可以通过按下按钮查看多个视频广告。问题是,关闭应用程序后,按后退按钮,然后再次打开它。然后,广告再也不会加载。我没有收到来自RewardedVideoAdListener的消息,我把Toast放在非常实用的功能中。根本就没有反馈。我应该能够在onRewardedVideoAdFailedToLoad中查看Toast,但即便如此。就好像代码完全无法执行。
正如我所说,我是Android新视频广告的新手。也许我做错了什么,但我无法弄清楚是什么。我已经搜索了互联网,但我找不到任何答案。有些人在加载广告时提到了问题,但在应用程序关闭并再次打开后没有提到广告未加载的具体问题。我也检查了这个问题,但没有人回答: Question on StackOverflow
我在不同的手机上运行应用程序,我总能找到这个问题。
任何人都可以帮助我吗?
抱歉我的英文。我不是母语人士。
以下是我主要活动中的代码:
public class MainActivity extends AppCompatActivity implements RewardedVideoAdListener {
private Button mWatchButton;
private TextView mRewardLabel;
private RewardedVideoAd mAd;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWatchButton = (Button)findViewById(R.id.btn_watch);
mAd = MobileAds.getRewardedVideoAdInstance(this);
mAd.setRewardedVideoAdListener(this);
loadAd();
mWatchButton.setEnabled(false);
mWatchButton.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
if(mAd.isLoaded()){
mAd.show();
}
}
}
);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
private void loadAd(){
if(!mAd.isLoaded()){
mAd.loadAd("ca-app-pub-3940256099942544/5224354917", new AdRequest.Builder().build());
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onRewardedVideoAdLoaded() {
mWatchButton.setEnabled(true);
Toast.makeText(this, "onRewardedVideoAdLoaded", Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoAdOpened() {
Toast.makeText(this, "onRewardedVideoAdOpened", Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoStarted() {
Toast.makeText(this, "onRewardedVideoStarted", Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoAdClosed() {
Toast.makeText(this, "onRewardedVideoAdClosed", Toast.LENGTH_SHORT).show();
mWatchButton.setEnabled(false);
loadAd();
}
@Override
public void onRewarded(RewardItem rewardItem) {
Toast.makeText(this, "onRewarded", Toast.LENGTH_SHORT).show();
mRewardLabel.setText(String.format(Locale.getDefault(), "You got %d %s!", rewardItem.getAmount(), rewardItem.getType()));
}
@Override
public void onRewardedVideoAdLeftApplication() {
Toast.makeText(this, "onRewardedVideoAdLeftApplication", Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoAdFailedToLoad(int i) {
Toast.makeText(this, "onRewardedVideoAdFailedToLoad", Toast.LENGTH_SHORT).show();
}
@Override
public void onPause() {
super.onPause();
mAd.pause(this);
}
@Override
public void onResume() {
super.onResume();
mAd.resume(this);
}
@Override
public void onDestroy() {
super.onDestroy();
mAd.destroy(this);
}
}
以下是我布局的代码:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.xxxxxx.MainActivity"
tools:showIn="@layout/activity_main">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
android:id="@+id/textView" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Ver o anúncio"
android:id="@+id/btn_watch"
android:layout_below="@+id/textView"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginTop="58dp"/>
</RelativeLayout>
我在Android Studio的logcat中没有收到任何警告或错误消息。
我正在使用:
classpath 'com.google.gms:google-services:3.0.0'
和
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.google.firebase:firebase-ads:9.4.0'
}
apply plugin: 'com.google.gms.google-services'
答案 0 :(得分:1)
当应用再次进入前台时,请求另一个广告:
@Override
public void onResume() {
super.onResume();
loadAd();
}
