Error while trying to run admob ad on Android Studio

I am trying to install an admob ad on my webview app that I developed with Android Studio but the app keeps crashing now and I can't seem to get the code right.... everywhere I read about the Android SDK is different information....
This is the error I keep getting and I can't seem to figure out why I am getting it..

I am using Andoid Studio to develop an app and while opening the app , I am not able to see my web page ,a white screen is coming. I saw the console and find this error

When I see my manifest file, its seems fine for me and also MainActivity.java seems good for me.

What do these Android logcat warnings mean?

It doesn't seem to impact anything in my app... yet. I'm using the Android support libraries for the first time (my projects to date have not used support libraries), but this is a new project without much in the way of customization yet. Activities were generated by Android Studio 0.9.2 and implement Navigation Drawer.
Running this on a Verizon Samsung Galaxy SIII running Android 4.4.2. Project is set to minSDK of 15 and targeted SDK of 21.

If I'm guessing (and I am), I'm missing a library that android.support.v7 requires. But I have no idea what or where to find it.

I would like to add on top of what #Monte Creasor explained.
I have had the same issue and consulted this bug report which basically says that the problem might be caused by com.android.support:appcompat-v7:21.0.3, on of the main dependencies required to use Android's new Layout capabilities.
Try going back to the v7:20.0.0, this should solve the issue as it did for me and this bug report writer.
Actually all you have to change is in the app build.gradle the line:
compile 'com.android.support:appcompat-v7:21.0.3' or whatever later version you have
to
compile 'com.android.support:appcompat-v7:20.0.0'

These errors occur when you run android studio 1.0 using the sliding drawer sample WITHOUT adding any additional code and using all the defaults the project creation wizard offers. So it would seem to be an Android Studio problem and not a developer coding error.

I had the same issue, also I wasn't able to get my ListFragment scrollable. Used v4 support library 21.0.3 before and upgraded to 22.0.0.
This fixed my problems!

I'm currently going through my logs generated from using Sony's remote device lab, the same warning appears so it's not a Android Studio problem. I suspect its a problem with the ActionBar theme used during the development of the application.

Question :
1) It just loads the blanks google page. What else I need to mention?
2) Where can I find the way that will work on all version , as I see many addition in manifest file with change in android version.
Sorry for such a big post.
Few Points : after reading many post in StackOverflow,
1) It says to add me
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
lines in Manifest. Earlier it was not required as I run the same app without using this.
2) It says to change
class="com.google.android.gms.maps.Fragment"
to
class="com.google.android.gms.maps.SupportMapFragment"
Otherwise it will crash saying xml inflation issue.
3) There is chance of that the application is signed with different keystore and thus the API key wont work. So I signed the apk with new keystore and used the same sha for generating the API key.

Unable to find classes in Android library file

I have created a very simple Android app just to work with functionality. Within the app I would like to call a web service client to retrieve and display some data. I think I have succesfully imported and referenced the jar file (i.e. library). It appears to be instantiating the class successfully but when that class is referencing another class within the jar/library it throws a class not found error. Any ideas??? Anything else I can provide to help answer???
Here is my code:
package mhcs.android.ehd;
import mhcs.services.client.EHD.EHDClient;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class GetTicketDescription extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
EHDClient client = new EHDClient();
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String title = getString(R.string.title);
setTitle(title); // done so that we can change the default title
//get handles to editText and button widgets
final EditText eText = (EditText) findViewById(R.id.editText1);
final Button button = (Button) findViewById(R.id.button1);
eText.setText(client.getTicketDescription("MMLZ-8LVRMK"));
button.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View v) {
//get the String entered into the editText widget
CharSequence editText = eText.getText();
//display the toast
Toast.makeText(GetTicketDescription.this, editText, Toast.LENGTH_LONG).show();
}
});
}
}
Here is the error:

Find Properties -> Java Build Path -> Order and Export
Change Android Dependencies order

Try to create a new folder called libs under your project and put the .jar file there...

I had the same problem, I tried to mark the Android Private Libraries under Order and Export and it didn't work for me. Then I noticed that my libs folder wasn't referenced under the Java Build Path. So I just added it to Libraries and it worked.

Go to
Project> Build Path >Configure Build Path
Check the Libraries you wanted and hit ok
