import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;

public class MainActivity extends AppCompatActivity {
    private AdView mAdView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mAdView = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        mAdView.loadAd(adRequest);
    }
}

這是我得到的錯誤：

08-01 10:01:43.200 3210-3210/com.example.chawkii.myapplication E/Ads: JS engine could not be obtained. Cancelling ad request

我正在學習發展，我也看不到錯誤，對於權限也很好，但是我的測試廣告沒有加載到android設備模擬器中。 有什么幫助嗎？

Answer 1

經過大量研究，我找到了解決此錯誤的方法，問題不是代碼，實際上是在我的模擬器中，因此我必須下載最新的API並將google play服務更新為最新版本，所以我可以看到廣告

Answer 2

 public class MyActivity extends Activity {
     private AdView mAdView;

     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

         LinearLayout layout = new LinearLayout(this);
         layout.setOrientation(LinearLayout.VERTICAL);

         // Create a banner ad. The ad size and ad unit ID must be set before calling loadAd.
         mAdView = new AdView(this);
         mAdView.setAdSize(AdSize.SMART_BANNER);
         mAdView.setAdUnitId("myAdUnitId");

         // Create an ad request.
         AdRequest.Builder adRequestBuilder = new AdRequest.Builder();

         // Optionally populate the ad request builder.
         adRequestBuilder.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);

         // Add the AdView to the view hierarchy.
         layout.addView(mAdView);

         // Start loading the ad.
         mAdView.loadAd(adRequestBuilder.build());

         setContentView(layout);
     }

     @Override
     public void onResume() {
         super.onResume();

         // Resume the AdView.
         mAdView.resume();
     }

     @Override
     public void onPause() {
         // Pause the AdView.
         mAdView.pause();

         super.onPause();
     }

     @Override
     public void onDestroy() {
         // Destroy the AdView.
         mAdView.destroy();

         super.onDestroy();
     }
 }

Answer 3

您需要將模擬器（或其他設備，如果需要）添加為“測試設備”。 測試廣告只會在測試設備上展示。

為此，您在構建AdRequest時需要調用addTestDevice 。

更改此行：

AdRequest adRequest = new AdRequest.Builder().build();

至：

AdRequest adRequest = new AdRequest.Builder()
    .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
    .build();

Answer 4

1. Sign into your AdMob account.

2. Click on Monetize tab.

3. Select or Create the app and choose the platform.

4. Select the ad format either Banner or Interstitial and give the ad unit a name.

5. Once the ad unit is created, you can notice the Ad unit ID on the dashboard. An example of ad unit id look like ca-app-pub-0664570763252260/3326342124

Create as many ad units required for your app.
android-admob-creating-ad-unit

Create two ad units, one for banner and other for interstitial as we need to use the ad unit IDs in the next section.
3. Creating New Project

1. Create a new project in Android Studio from File ⇒ New Project. When it prompts you to select the default activity, select Empty Activity and proceed.

2. Open build.gradle and add play services dependency as AdMob requires it.

compile ‘com.google.android.gms:play-services-ads:8.4.0’

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'

    compile 'com.google.android.gms:play-services-ads:8.4.0'
}

3. Add the Ad unit IDs to your strings.xml. Open strings.xml located under res ⇒ values and add the ad units of both Banner and Interstitial.

<resources>
    <string name="app_name">AdMob</string>
    <string name="title_activity_second_activiy">Interstitial</string>
    <string name="msg_welcome">Welcome to Admob. Click on the below button to launch the Interstitial ad.</string>
    <string name="btn_fullscreen_ad">Show Fullscreen Ad</string>

    <!-- AdMob ad unit IDs -->
    <string name="banner_home_footer">ca-app-pub-0664570763252260/3326522424</string>
    <string name="interstitial_full_screen">ca-app-pub-0664570763252260/1769900428</string>

</resources>

4. Open AndroidManifest.xml and add the below mentioned permissions and other properties.

> Add INTERNET & ACCESS_NETWORK_STATE permissions.

> Add google play services version meta-data.

> Add the AdActivity adding configChanges and theme attributes.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="info.androidhive.admob">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />

        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <!--Include the AdActivity configChanges and theme. -->
        <activity
            android:name="com.google.android.gms.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
            android:theme="@android:style/Theme.Translucent" />
    </application>

</manifest>

3.1 Adding Banner Ad

Banner ads occupies only a portion of the screen. I am adding a banner ad in my main activity aligning to bottom of the screen. In order to add the banner ad, you need to add com.google.android.gms.ads.AdView element to your xml layout.

<com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ads:adSize="BANNER"
        ads:adUnitId="@string/banner_home_footer">
    </com.google.android.gms.ads.AdView>

5. Open the layout file of your main activity (activity_main.xml) and add the AdView widget. I am also adding a button to launch another in which we’ll try Interstitial ad.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    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"
    tools:context="info.androidhive.admob.MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/msg_welcome" />

    <Button android:id="@+id/btn_fullscreen_ad"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="@string/btn_fullscreen_ad"/>

    <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        ads:adSize="BANNER"
        ads:adUnitId="@string/banner_home_footer">
    </com.google.android.gms.ads.AdView>
</RelativeLayout>

6. Open MainActivity.java and modify the code as shown.

> Create an instance of AdRequest and load the ad into AdView.

> Ad the AdView life cycle methods in onResume(), onPause() and in onDestroy() methods.

package info.androidhive.admob;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import com.google.android.gms.ads.AdListener;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;

public class MainActivity extends AppCompatActivity {

    private AdView mAdView;
    private Button btnFullscreenAd;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mAdView = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder()
                .build();
        mAdView.loadAd(adRequest);

        btnFullscreenAd = (Button) findViewById(R.id.btn_fullscreen_ad);
        btnFullscreenAd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(MainActivity.this, SecondActivity.class));
            }
        });
    }

    @Override
    public void onPause() {
        if (mAdView != null) {
            mAdView.pause();
        }
        super.onPause();
    }

    @Override
    public void onResume() {
        super.onResume();
        if (mAdView != null) {
            mAdView.resume();
        }
    }

    @Override
    public void onDestroy() {
        if (mAdView != null) {
            mAdView.destroy();
        }
        super.onDestroy();
    }
}

Now if you run the app, you should see a banner ad at the bottom of your screen.

Answer 5

您尚未添加初始化語句。 將此添加到onCreate（）{

..... .... MobileAds.initialize（this，“ ca-app-pub-3940256099942544〜3347511713”）;

}
