admob account is not banned, i tested on 3 devices.permissions in manifest is right

Try removing the builder.addTestDevice("xxxx")
Somthing like this
AdRequest.Builder builder = new AdRequest.Builder();
AdRequest ad = builder.build();
bannerAd.loadAd(ad);
I integrate Ads everyday and I have never needed to add the test device, it always shows test ads if you use a test id for Ads
You can use this test banner id
ca-app-pub-3940256099942544/6300978111
and replace this id when you will generate your final APK

Just a guess. It could be you're assigning the testDevice after building the ad?
AdRequest ad = builder.build();
builder.addTestDevice("xxxx");
Swtich the two lines:
builder.addTestDevice("xxxx");
AdRequest ad = builder.build();

ADMOB - The following classes could not be instantiated: - com.google.android.gms.ads.AdView

I updated my old admob to the new admob. I downloaded SDK, imported google play service library and done everything in google documantation. But when I add the xml code:
<com.google.android.gms.ads.AdView android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adUnitId="ca-app-pub-XXXXXXXXXXXXXXX/YYYYYYYY"
ads:adSize="BANNER"/>
I get the following message in error log:
The following classes could not be instantiated: - com.google.android.gms.ads.AdView
There is Manifest XML code:

Coul you help me please?

You can create AdView in java code, but not in xml.
it works for me:
private AdView adView;
private static final String AD_UNIT_ID = "XXXXXXX";
#Override
public void onCreate(){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create an ad.
adView = new AdView(this);
adView.setAdSize(AdSize.BANNER);
adView.setAdUnitId(AD_UNIT_ID);
// Add the AdView to the view hierarchy. The view will have no size
// until the ad is loaded.
LinearLayout layout = (LinearLayout) findViewById(R.id.linearLayout);
layout.addView(adView);
// Create an ad request. Check logcat output for the hashed device ID to
// get test ads on a physical device.
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
.addTestDevice("INSERT_YOUR_HASHED_DEVICE_ID_HERE")
.build();
// Start loading the ad in the background.
adView.loadAd(adRequest);
}
#Override
public void onResume() {
super.onResume();
if (adView != null) {
adView.resume();
}
}
#Override
public void onPause() {
if (adView != null) {
adView.pause();
}
super.onPause();
}
/** Called before the activity is destroyed. */
#Override
public void onDestroy() {
// Destroy the AdView.
if (adView != null) {
adView.destroy();
}
super.onDestroy();
}

Have you edited the proguard-project.txt? If not then open the proguard-project.txt file and put these lines there...
-keep public class com.google.android.gms.ads.** {
public *;
}
-keep public class com.google.ads.** {
public *;
}
Set target=android-13 or higher in your project.properties.

Yesterday I had my first app integrated with admob and what I did is just I added a .jar Library to Java Build Path,. When in Manifest file I added these lines above closing application tag:
<activity
android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />
and these permissions:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
This is how my Manifest.xml looks like:

When in my main_acitivty.xml I added these lines of code where I actually want to see my Ad Banner:
<com.google.ads.AdView

android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

ads:loadAdOnCreate="true" >
</com.google.ads.AdView>
I actually did not write any code in my .java file. Because you can choose whetever to implement AdMob via XML or programatically.

My UI code doesn't show anything in emulator

I'm starting out in android development and I grabbed a sample code snippet from a book for a few text fields on an interface. I checked over and over that my code is identical to that in the book, but every time I compile and run, I get nothing but a black screen in the emulator.
Here's my code:
package me.kevinossia.mystuff;
import android.app.Activity;
import android.os.Bundle;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;
import android.widget.TextView;
public class MainActivity extends Activity
{
private LinearLayout nameContainer;
private LinearLayout addressContainer;
private LinearLayout parentContainer;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
createNameContainer();
createAddressContainer();
createParentContainer();
setContentView(parentContainer);
}
private void createNameContainer()
{
nameContainer = new LinearLayout(this);
nameContainer.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
nameContainer.setOrientation(LinearLayout.HORIZONTAL);
TextView nameLbl = new TextView(this);
nameLbl.setText("Name: ");
nameContainer.addView(nameLbl);
TextView nameValueLbl = new TextView(this);
nameValueLbl.setText("Kevin");
nameContainer.addView(nameValueLbl);
}
private void createAddressContainer()
{
addressContainer = new LinearLayout(this);
addressContainer.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
addressContainer.setOrientation(LinearLayout.VERTICAL);
TextView nameLbl = new TextView(this);
nameLbl.setText("Address: ");
addressContainer.addView(nameLbl);
TextView nameValueLbl = new TextView(this);
nameValueLbl.setText("26662");
addressContainer.addView(nameValueLbl);
}
private void createParentContainer()
{
parentContainer = new LinearLayout(this);
parentContainer.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
parentContainer.setOrientation(LinearLayout.VERTICAL);
parentContainer.addView(nameContainer);
parentContainer.addView(addressContainer);
}
}
What am I missing here?
Here's my manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="me.kevinossia.mystuff.tutorial"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="15" />
<application android:label="#string/app_name"
android:icon="#drawable/ic_launcher"
android:theme="#style/AppTheme">
</application>
</manifest>
Here's the new manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="me.kevinossia.mystuff.tutorial"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="15" />
<application android:label="#string/app_name"

<action android:name="android.intent.action.MAIN" android:theme="#android:style/Theme.Holo" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

You don't have anything as your launcher in your manifest. You should have something like
<application android:label="#string/app_name"
android:icon="#drawable/ic_launcher"
android:theme="#style/AppTheme">
<activity
android:name="me.kevinossia.mystuff.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" android:theme="#android:style/Theme.Holo" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
inside the <application> tag. These are the important lines for that.
<intent-filter>
<action android:name="android.intent.action.MAIN" >
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
depending on your app
manifest.xml

Hi I have a Android game app developed using android cocos2d i need to integrate admob i have included the following code but banner ad is not displaying please help regarding this your answers will be appreciated and it would be a great help. thank you.
public class MainActivity extends Activity {
private CCGLSurfaceView mGLSurfaceView;

Please review all these additions in your project.
In Java class:
AdView layout = (AdView)this.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest();
//adRequest.setTesting(true);
layout.loadAd(adRequest);
In Layout:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads">
<com.google.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adSize="BANNER"
ads:adUnitId="your key" />
</LinearLayout>
In Manifest:
<activity android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation" />
I have worked with AdMob Lib. Ver. 4.0.4 which worked fine in my case.

Try this code
LinearLayout.LayoutParams adParams = new LinearLayout.LayoutParams(
getWindowManager().getDefaultDisplay().getWidth(),
getWindowManager().getDefaultDisplay().getHeight()+getWindowManager().getDefaultDisplay().getHeight()-50);
AdView ad = new AdView(this, AdSize.BANNER, "admob_id");
adParams.addView(ad);
AdRequest r = new AdRequest();
//r.setTesting(true);
ad.loadAd(r);

Make sure that you included correct ID and have correspond permissions for your app.
In addition it would be good to implement ADListener that really displays what how its going with ads rendering.
Also don't forget to set test mode to query ads, AdMob guys can just ban you for irresponsible clicks.

for latest Ads in Android
use below code
AdView layout = (AdView) this.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder()
.build();
//adRequest.setTesting(true);
layout.loadAd(adRequest);
beacuse AdRequest class final class so we can not create object.
