AbMod from Google Play services will perform undesired auto scrolling

[Yan Cheng Cheok]

I were using AdMob from Google Play services version 13. I realize, when I place the advertisement withinScrollView, AdMob will try to perform undesired auto scrolling, after it fetches the advertisement successfully from server.

package com.example.admob_bug;

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

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.LinearLayout;

public class MainActivity extends Activity {

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

        // Create the adView.
        adView = new AdView(this);
        adView.setAdUnitId("a151b03485063e0");
        adView.setAdSize(AdSize.BANNER);

        // Lookup your LinearLayout assuming it's been given
        // the attribute android:id="@+id/mainLayout".
        LinearLayout layout = (LinearLayout)findViewById(R.id.advertisement);

        // Add the adView to it.
        layout.addView(adView);

        // Initiate a generic request.
        AdRequest adRequest = new AdRequest.Builder().build();

        // Load the adView with the ad request.
        adView.loadAd(adRequest);        
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public void onPause() {
        adView.pause();
        super.onPause();
    }

    @Override
    public void onResume() {
        super.onResume();
        adView.resume();
    }

    @Override
    public void onDestroy() {
        adView.destroy();
        super.onDestroy();
    }

    private AdView adView;    
}

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    ...
    ...

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Large Text 7"
        android:layout_margin="30dp"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <LinearLayout
        android:id="@+id/advertisement"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

    </LinearLayout>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Large Text 8"
        android:layout_margin="30dp"
        android:textAppearance="?android:attr/textAppearanceLarge" />        

</LinearLayout>

You will realize this problem, after you wait for around 10 seconds (Depending on network quality), after advertisement is loaded.

Is there any workaround to prevent auto scrolling?

Hey there Yan!

I can't reproduce this. What device are you having a problem on?

Hi Amy,

Sorry for late reply. I just realize there is reply in this thread. I don't receive any email notification.

My device is Nexus S, Android 4.1.2

To-date, I testing using latest Google Play Service (14)

Problem still occur to-date. The list will auto scroll toward bottom

[Large Text 7]

[advertisement]

Any hint on solving this problem is very much appreciated, as AdMob jar SDK is going to depreciated on August 1, 2014

Thanks.

Hi all,

Is there any update on this issue? :(

As having "auto scrolling" bug will create a bad user experience. If I can't find out a workaround on this issues before depreciation, I may need to switch to other advertising platform provider. That is not something I would like it to happen, as I'm a very happy AdMob user.

Thank you for your support.

Hi Yan,

The AdMob Ads if set inside a ScrollView will always scroll. However, what I have done is edited the activity_main.xml- setting up a Relative Layout in which there is a scrollview and a LinearLayout (which contains your ad) at the bottom. 

So when you scroll, the Ad doesn't scroll, it always remain in the view. 

Best,
Kunal

Having advertisement at the bottom is not something I want to achieve. I only wish is to place it at the middle of scroll view.

Any how, I got a pretty nice workaround from others. Here's the workaround.

<LinearLayout
        android:id="@+id/advertisement"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

        android:descendantFocusability="blocksDescendants"
        android:orientation="vertical" >
</LinearLayout>
