I have seen many similar topics at this forum, but none of them solved my problem. In my code I have something like this:
import com.google.android.gms.R;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
...
AdView adView = (AdView)this.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice("TEST_DEVICE_ID")
.build();
adView.loadAd(adRequest);
And it shows me 2 errors(I marked the red marks as bold text):
-In first line: "AdView adView = (AdView)this.findViewById(R.id. adView );" - adView cannot be resolved or is not a field
-And in last line: " adView.loadAd(adRequest) ;" - The type android.view.ViewGroup cannot be resolved. It is indirectly referenced from required .class files
I have no idea what causes it. I also had a problem with lack of "layout" folder before, but I generated it with eclipse new>other>android XML layout file. Should I also somehow link it using manifest?
PS It's libGDX project
EDIT: Here is my layout/activity_main.xml file:
<?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" >
<com.google.android.gms.ads.AdView
android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
ads:adSize="BANNER"
ads:adUnitId="@string/banner_ad_unit_id">
</com.google.android.gms.ads.AdView>
your problem is with this line
import com.google.android.gms.R;
remove this and import your package .R file
import <package name>.R
I have same issue in cocos2dx, I don't have layout file and I want to dislplay admob banner ads, please try this solution without creating layout xml file:
inside onCreate
function :
adView = new AdView(this);
adView.setAdSize(AdSize.BANNER);
adView.setAdUnitId("YOUR ID");
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);
adView.setBackgroundColor(Color.BLACK);
adView.setBackgroundColor(0);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
int width = getDisplaySize(getWindowManager().getDefaultDisplay()).x;
LinearLayout.LayoutParams adParams = new LinearLayout.LayoutParams(
width, LinearLayout.LayoutParams.WRAP_CONTENT);
addContentView(adView, adParams);
and getDisplaySize
method:
// Helper get display screen to avoid deprecated function use
private Point getDisplaySize(Display d)
{
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
{
return getDisplaySizeGE11(d);
}
return getDisplaySizeLT11(d);
}
@TargetApi(Build.VERSION_CODES.HONEYCOMB_MR2)
private Point getDisplaySizeGE11(Display d)
{
Point p = new Point(0, 0);
d.getSize(p);
return p;
}
private Point getDisplaySizeLT11(Display d)
{
try
{
Method getWidth = Display.class.getMethod("getWidth", new Class[] {});
Method getHeight = Display.class.getMethod("getHeight", new Class[] {});
return new Point(((Integer) getWidth.invoke(d, (Object[]) null)).intValue(), ((Integer) getHeight.invoke(d, (Object[]) null)).intValue());
}
catch (NoSuchMethodException e2) // None of these exceptions should ever occur.
{
return new Point(-1, -1);
}
catch (IllegalArgumentException e2)
{
return new Point(-2, -2);
}
catch (IllegalAccessException e2)
{
return new Point(-3, -3);
}
catch (InvocationTargetException e2)
{
return new Point(-4, -4);
}
}
