com.google.ads.AdView类错误

Question

Hello I am new to android dev and admob. I am trying to make a simple test app with a button, a couple pages and admob at the bottom. Everything works fine until I try implementing admob. Here is my code:

HelloAndroid.java:

package com.manny.HelloAndroid;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;

public class HelloAndroid extends Activity {
    /** Called when the activity is first created. */
    private static final int ACTIVITY_CREATE = 0;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        setContentView(R.layout.main);
        ImageView image = (ImageView) findViewById(R.id.test_image);
        //image.setScaleType(ImageView.ScaleType.FIT_XY);

    }
    public void onClick(View v){
        Intent i = new Intent(this, HelloPage2.class);
        startActivityForResult(i, ACTIVITY_CREATE);
    }
}

main.xml:

<?xml version="1.0" encoding="utf-8"?>

I am using GoogleAdMobAdsSdkAndroid-6.0.0. Again I am very new to this and I have tried using examples off multiple sites but the app continues to crash when it hits a page with admob in it. If someone can help me it would be much appreciated. Thank you. If more code is needed let me know.

Answer 1

Have you recently updated your Android Tools to r17 or higher? If so, you need to create a libs/ folder in your project, and physically put the SDK in the project. Or, in the Java Build Path, you must Order and Export the SDK jar.

Otherwise, the jar doesn't get included when your apk gets compiled, and all hell breaks loose when you run AdMob code at runtime.

NOTE: This applies to any library your project references.

Answer 2

For me it worked like this.

• close eclipse
• add manually the sdk ad jar file in your project's "libs" folder
• open eclipse
• refresh your project till the sdk jar appears on libs folder
• go to your project's properties > Java Build Path > Library Tab and choose "add Jars" instead of an external one. and select the sdk from the list below.
• go to "Order and Export" tab and select again the SDK
• click ok AND ITS DONE.

Then just add the proper code in the manifest and the xml.

Answer 3

I was experiencing this, too. The build path didn't seem to work no matter what I did. So I exited Eclipse, created a new libs folder in the workbench package directory. Added the GoogleAdMobAdsSdk-6.0.1.jar to that folder. I DID NOT add the whole SDK, just the jar file. Then restarted Eclipse. I had to refresh the project inspector column to show the changes I made outside of Eclipse. It showed the new libs folder and jar file, but it still didn't work... Then I right clicked on the new libs folder and set it as a SOURCE FOLDER. NOW EVERYTHING WORKS!

Im using Eclipse Version: Indigo Service Release 2 Build id: 20120216-1857

Android Development Tools 18.0.0.v201203301601-306762

It seems that maybe the tools are ahead of the documentation... or some kind of Eclipse bug.... Very aggravating!

Answer 4

I had the same problem and noticed that ordering the export list is also important.
This is mine, this way it works:

Answer 5

What I did - is working for me now - API Level 17 For admob:
- Add adview code to your Layout with appropriate ID
- Add Admob manifest code to your project manifest file
- Add an external GoogleAdmobAdsSDK....jar Jar file to your Library (in Properties\\Java Build path)
- Check to choose GoogleAdmobAdsSDK....jar in tab Order and Export
- Restart your ADT

DEGUB = WORKING NOW.

Answer 6

In Android Studio: 1. Paste the Google AdMob SDK into the libs folder for your project 2. Add an entry to dependencies section of your build.gradle for the project pointing at the jar. 3. Rebuild your project

dependencies {
...
compile files('libs/GoogleAdMobAdsSdk-6.4.1.jar', '... other entries...')
}

Note that compile files takes multiple jar entries. If you already have a compile files entry you can just add to it by separating entries with a comma.

Answer 7

同样的错误出现在我身上，我用几个简单的步骤解决你需要从你的项目中删除appcombat依赖项，以删除右键单击你的项目 - > android->删除app的战斗，并确保你已选择android 4.2.2然后导入google admob jar进入你的项目。
