[英]Can't get AdMob to work (using Android, LibGDX)
我做了很多研究,但由於我不熟悉放置應用內廣告(這是我第一次制作應用,而且我第一次使用廣告),因此沒有多大意義。
這是我更新的MainActivity.java代碼:
package com.me.mygdxgame;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;
import com.badlogic.gdx.backends.android.AndroidApplication;
import com.badlogic.gdx.backends.android.AndroidApplicationConfiguration;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdSize;
import com.google.android.gms.ads.AdView;
public class MainActivity extends AndroidApplication {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main); //Changed it back to main, got rid of an error
AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration();
cfg.useGL20 = true;
initialize(new MyGame(), cfg);
AdView adView;
adView = new AdView(this);
adView.setAdSize(AdSize.BANNER);
adView.setAdUnitId("My Ad Unit ID (just using this string for posting purposes");
LinearLayout layout = (LinearLayout) findViewById(R.id.normal); //Changed R.id.linearlayout to R.id.normal. After looking at my R.java class, I saw that there was no id.linearlayout, so I changed it to R.id.normal, which did exist.
layout.addView(adView); //This is line 44, where the NullPointer is caused
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);
}
}
這是更新的AndroidManifest XML代碼:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.me.mygdxgame"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="17" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:allowBackup="true"
android:icon="@drawable/testing"
android:label="@string/app_name" >
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
<activity
android:name=".MainActivity"
android:label="Flappy Nerd"
android:screenOrientation="portrait"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.google.android.gms.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
</application>
</manifest>
這是main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/normal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
</LinearLayout>
這是logcat:

這是一個更新的LogCat:當我拿出似乎導致NullPointers“layout.addView(adView);”的代碼行時,應用程序運行正常,但我從LogCat獲取這些消息:
03-16 17:04:06.723: E/GooglePlayServicesUtil(11199): The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.
03-16 17:04:09.265: I/Ads(11199): Ad finished loading.
03-16 17:05:09.269: I/Ads(11199): Ad is not visible. Not refreshing ad.
您似乎錯過了Manifest
文件中廣告的activity
部分:
<activity
android:name="com.google.android.gms.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />
你必須調整你的所有路線。 如果您可以編譯但不起作用,那么您可能正在使用已棄用的AdMob
版本。 您必須將google-play_lib
外部庫導入到項目中, 這里有一個如何操作的鏈接 。
你的代碼太亂了!
你應該修復幾個錯誤。 為了避免錯誤你的setContentView(R.layout.main);
必須是super.onCreate(savedInstanceState);
之后的第一行super.onCreate(savedInstanceState);
對我來說最令人困惑的是:
為什么你在App的Manifest
聲明了RelativeLayout
? 它必須在main.xml
聲明。 這是NullPointerException
的原因。 之所以會發生這種情況,是因為R.id.mainLayout
在布局中找不到此ID,因此layout
變量為null
並且在調用時會導致崩潰(因為它在清單中被錯誤地聲明)。
作為@yugidroid,你的代碼非常混亂! :P但你最終會得到它,別擔心!
最重要的是,不要在你的清單上放置布局,他們不去那里! 在您的文件夾/布局(在項目中)創建一個名為“activity_main.xml”的新xml文件,並用以下內容填充:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/linearLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"></LinearLayout>
</RelativeLayout>
在您的java文件中,更改為
adView.setAdUnitId("xx-xxx-xxx-1234567890123456/1234567890"); //Change the numbers to what google sent you in the email!!!
和Adrequest改為
AdRequest adRequest = new AdRequest.Builder().build();
(不推薦用於測試,但現在它會這樣做)
我建議您再次閱讀文檔,但這非常直截了當https://developers.google.com/mobile-ads-sdk/docs/#play https://developers.google.com/mobile-ads- SDK /文檔/ AdMob廣告/基本面#游戲
我打賭你得到了NullPointerException
findViewById(R.id.normal)
幾乎可以肯定,使用#initialize方法調用#setContentView並用其他東西替換R.layout.main。
