i'm new here and i'm a beginner of android apps developer! and i have a problem:
it's main.xml:
<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>
but when i debug my app this error will be shown in ErrorLog window:
AndroidManifest: Ignoring unknown 'WebView' XML element
edit: problem solved and the above code is modified and correct code!!

Remove this part of the code from WebView xmlns:android="http://schemas.android.com/apk/res/android" and add android:layout_width and android:layout_height properties to your buttons.

LinearLayout XML error Android

I'm trying to fix this so badly but I couldn't find where I've gone wrong.
The message:
Element type "LinearLayout" must be followed by either attribute specifications, ">" or "/>".
Why do I get this? Any ideas?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:weightSum="100"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
**<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_weight="70"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#0000FF"
android:padding="20dp"
android:paddingBottom="10dp"
android:gravity="center_horizontal">
</LinearLayout>
</LinearLayout>
It's a pretty self-explanatory error message.
You didn't close your LinearLayout tag. Add a > after android:orientation="vertical".
You missed a ">" at the end:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:weightSum="100"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
Your first LinearLayout tag isn't closed. Add a > to the end of it, like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:weightSum="100"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
^
Error clearly states that you missed the closing tag. Every Layout and its attribute needs to have their own opening and closing tag. Add
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_weight="70"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
or
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_weight="70"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>

android you must supply a layout_width attribute at line 7

I have been trying to run this code but getting this error since last 1 week.
Please help!
I have already declared layout:width.
Tried with layout.width in sliding drawer and replacing dp wit dip but still got the same error.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<SlidingDrawer
android:id="#+id/drawer"
android:width="320dp"
android:height="440dp"
android:orientation="vertical"
android:content="#+id/content"
android:handle="#+id/handle">
<ImageView
android:id="#+id/handle"
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/ic_launcher"/>
<AnalogClock
android:id="#+id/content"
android:background="#D0A0A0"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</SlidingDrawer>
</RelativeLayout>
Layout tags are mandatory tags I believe. You have not supplied layout_width and layout_height to your SlidingDrawer
android:layout_width="fill_parent"
android:layout_height="fill_parent"

Adding Admob into ScrollView -> AdBanner disappears

Hey folks
I managed to implement Admob into a normal linear layout so far.
Now I added a additional scrollview and the adbanner disappeared. I don´t know what I can do against it.
Follows the code from the .xml where I added the scrollview:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout"
android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="match_parent">
<ScrollView android:id="#+id/scrollView1" android:layout_height="wrap_content" android:layout_width="match_parent">
<LinearLayout android:id="#+id/linearLayout1" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical">
[whole bunch of layout elements whoch shouldn´t affect the adbanner]
</LinearLayout>
</ScrollView>
In my linear layout ,where the adbanner still works, the whole adbanner position was done in the main activitiy.java file (did this with help of the tutorial at taiic.com)
// Lookup R.layout.main
LinearLayout layout = (LinearLayout)findViewById(R.id.linearLayout);
// Create the adView
// Please replace MY_BANNER_UNIT_ID with your AdMob Publisher ID
String pubID = "xxxxxxxxxxxxxxxxxx";
AdView adView = new AdView(this, AdSize.BANNER, pubID);
// Add the adView to it
layout.addView(adView);
// Initiate a generic request to load it with an ad
AdRequest request = new AdRequest();
request.setTesting(true);
adView.loadAd(request);
Can anybody tell me what to change or what code to add when implementing an admob banner into a scrollview?
edit:
i tried to add
<com.admob.android.ads.AdView
android:id="#+id/ad"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
myapp:backgroundColor="#000000"
myapprimaryTextColor="#FFFFFF"
myapp:secondaryTextColor="#CCCCCC"
android:alignParentBottom="true"/>
between last two lines in the .xml
</LinearLayout>
[here]
</ScrollView>
but then im getting the error "error: Error parsing XML: unbound prefix"
cheers
About the parsing error:
Is this a typo in the question? myapprimaryTextColor="#FFFFFF" instead of myapp:primaryTextColor="#FFFFFF" . This would give you the xml parse error.
About the layouts:
Use a RelativeLayout. The working code is at the end of the post. First, some theory :)
Your ScrollView is taking the whole screen, that's why you don't see the admob view. When the scrollview is defined, all the screen is availabel to it, so it takes it. The admob view is actually drawn below your screen. It can be reproduced in this example:
non-working layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ScrollView android:id="#+id/scrollView1"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
<LinearLayout android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<EditText
android:layout_width="fill_parent"
android:layout_height="300dp"
android:text="Test1"
/>
<EditText
android:layout_width="fill_parent"
android:layout_height="300dp"
android:text="Test2"
/>
<EditText
android:layout_width="fill_parent"
android:layout_height="300dp"
android:text="Test3"
/>
</LinearLayout>
</ScrollView>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Test4"
/>
</LinearLayout>
If you use a RelativeLayout instead, you can set it up so the admob is aligned to the bottom of the screen, and the scrollview above it, taking the rest of the available space.

I used the admob xml version and that is what I use and it works. The ad is at the top. Just copy and paste and you will be scrolling along shortly.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res/com.yourproject.here"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adUnitId="a14dc1c9d6xxxxx"
ads:adSize="BANNER" />
<ScrollView android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true" >
[whole bunch of layout elements whoch shouldn´t affect the adbanner]
</ScrollView>

Add an AdMob Ad above a TabbedView?

I am getting an "Error parsing XML file: Unbound prefix" when I try to put my AdMob ad reference above a tabbed view. Any ideas how to fix that?
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:padding="5dp">
<com.admob.android.ads.AdView android:id="#+id/ad"
android:layout_width="fill_parent" android:layout_height="wrap_content"
myapp:backgroundColor="#000000" myapp:primaryTextColor="#FFFFFF"
myapp:secondaryTextColor="#CCCCCC" />
<TabWidget android:id="#android:id/tabs"
android:layout_width="fill_parent" android:layout_height="wrap_content" />
<FrameLayout android:id="#android:id/tabcontent"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:padding="5dp" />
</LinearLayout>
</TabHost>
You're using this:
myapp:backgroundColor
but I don't see any declaration of the 'myapp' prefix. so that might be the source of the error.
Just like the "android" namespace is declared in the xml like this:
xmlns:android="http://schemas.android.com/apk/res/android"
the 'myapp' namespace should have a declaration somewhere also
This answer seems related.
You need both the xmlns set correctly, as Nanne said, as well as your attributes defined in res/style/attrs.xml.
The xmlns appears to be:
xmlns:admob="http://schemas.android.com/apk/res/com.example.package"
For an example attrs.xml, check out the answer above.

Admob ads not showing - Android

My ads don't display at all, I think I've followed the documentation correctly but they still won't show. The program is basically a webview and I want the ad to display at the bottom.
Heres my layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:myapp="http://schemas.android.com/apk/res/man.utd.headlines"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<WebView
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<com.admob.android.ads.AdView
android:id="#+id/ad"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
myapp:backgroundColor="#000000"
myapp:primaryTextColor="#FFFFFF"
myapp:secondaryTextColor="#CCCCCC" />
</LinearLayout>
Any ideas?
EDIT: this is what I now have but it still doesn't appear to be quite right:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:myapp="http://schemas.android.com/apk/res/man.utd.headlines"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<com.admob.android.ads.AdView
android:id="#+id/ad"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
myapp:backgroundColor="#000000"
myapp:primaryTextColor="#FFFFFF"
myapp:secondaryTextColor="#CCCCCC" />
<WebView
android:id="#+id/webview"
android:layout_above="#id/ad"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
Your Problem is that the WebView will take all the space on the screen and there is no space left for the ads.
A LinearLayout will distribute the space on a first come first serve rule. If the first View takes all the space the second view won't get any space..
I would use a RelativeLayout and add the adds first with a layout_alignParentBottom attribute and then add the webview with a layout_above="id for the adds". This will ensure that the adds are always on the bottom of the screen even if the webview wont take all the space at the moment and the webview will always be above the adds.
I had the same problem, i fixed it this way:
LinearLayout as main layout, inside it linearLayout(for the ad) and a webview, set wrap_content on the linearlayout for the ad, so, it will first show an ad and then the rest of the screen will be the webview.
example of mine:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout
android:id="#+id/addmob"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
></LinearLayout>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:layout_width="fill_parent" android:id="#+id/rltvLayout1"
android:layout_height="fill_parent">
<LinearLayout android:id="#+id/linearLayoutwebview"
android:layout_height="wrap_content" android:layout_width="wrap_content"
android:orientation="vertical">
<WebView android:id="#+id/webView1"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:fitsSystemWindows="true" />
</LinearLayout>
<LinearLayout android:layout_width="fill_parent"
android:id="#+id/ad_layout" android:layout_height="wrap_content"
android:gravity="bottom" android:layout_alignParentBottom="true"
android:layout_alignBottom="#+id/home_layout">
<com.google.ads.AdView android:layout_width="wrap_content"
android:layout_height="wrap_content" ads:adUnitId="put here your ID"
ads:adSize="BANNER" android:id="#+id/adView" ads:refreshInterval="60" />
</LinearLayout>
</RelativeLayout>
