Question

请帮帮我。当我将admob添加到我的程序时，此代码无效。可能是我以错误的方式使用它。请建议我使用banner ad admob编辑代码。我应该在哪里添加admob代码？ Debug中没有错误，但应用程序未运行无法加载应用程序。谢谢。

Answer 1

您只需要在活动中使用以下内容：

{
  "rules": {
    ".read": "auth != null",
    ".write": "auth != null",

    "divisions": {
      ".indexOn": "index_num"
    },

      "districts": {
      ".indexOn": "index_num"
    },

  }
}

您添加的视图：

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

AndroidManifest.xml中的广告活动：

<RelativeLayout> 
 ...
    <com.google.android.gms.ads.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_ad_unit_id"
        android:id="@+id/adView">
    </com.google.android.gms.ads.AdView>

</RelativeLayout>

并且不要忘记AndroidManifest.xml中的权限：

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

将您的广告单元ID存储在strings.xml文件中。以下ID仅用于测试，请务必在发布应用之前对其进行更改。

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

检查所有这一切，它应该有效。

Answer 2

$this->db->where('sales'  >= 0)

$this->db->where('sales'  <= 10)

$this->db->where('sales'  >= 15)

$this->db->where('sales'  <= 20)

将此代码放入onCreate（），广告监听器中并检查错误代码比我说我给您解决方案的错误代码。

Answer 3

您应该重写LifeCycle方法并在其中清理资源。

@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();
