How can I solve this problem?
You have to add the Google Play Service SDK as a project in your workspace (assuming you're using Eclipse). This is described here.
The next step is to link this project with your Android project as a library. Here's the docu about this step.

It looks like AppsInfoMainActivity extends BaseActivity but BaseActivity extends something else which is probably not valid. Make sure it is extending Activity or an AppCompat Activity class and that the imports are correct
Make sure your Intent Filter tag in the XML which contains MAIN also contains
<category android:name="android.intent.category.DEFAULT" />
I think there's a problem about your class path. Please check class path and if it's wrong correct it.
If it's extending Activity or an AppCompat Activity class and that the imports are right, maybe 2 versions of android-support-v4.jar in the dependency list,
but not all the versions are identical (check is based on SHA-1 only at this time).
All must be the same.
Hmm Maybe cleaning Project will help.
I solved it, It was because of I had so many libs included unnecessary :|
I am new in Android Development. I am working on cordova platform

I have updated my cordova to resolve but still same error however a few days ago it was working fine and i have build some apps.
First download Cordova jar file from following link:
http://www.java2s.com/Code/JarDownload/cordova/cordova-1.8.1.jar.zip
after that extract the folder and put cordova-1.8.1 inside your libs folder of project in eclipse
And right click on your project--> properties and Select Android from left pane and scroll to bottom remove the cordova library if added.
then clean and build your project.
My android application crashes every time I run/launch it on both the emulator and a real device and returns this error message: Unfortunately "application_name" has stopped!
This is what my logcat looks like:

You are attempting to call getSharedPreferences() from an initializer. You cannot safely call methods you inherit from Activity until after super.onCreate() is called.
I am trying to upload a text file to Amazon s3 from my android application. I am using the following code snippet provided by Amazon AWS.
private static CognitoCredentialsProvider sCredProvider;
public static CognitoCredentialsProvider getCredProvider(Context context) {
if(sCredProvider == null) {
Log.i("Util","reached utility");
Log.i("Util","Context"+context);
sCredProvider = new CognitoCredentialsProvider(
context,
Constants.AWS_ACCOUNT_ID,
Constants.COGNITO_POOL_ID,
Constants.COGNITO_ROLE_UNAUTH,
null);
Log.i("Util","returning scredprovider"+sCredProvider);
sCredProvider.refresh();
}
Log.i("Util","returning scredprovider"+sCredProvider);
return sCredProvider;
}
When the code passes through sCredProvider.refresh(); it throws the follow error.

Commenting out the line run the application fine. But I don't see the file uploaded to Amazon S3. I did setup to Amazon Cognito credential provider.
The source code can be found here.
CognitoCredentialsProvider.refresh() will make a network request to fetch Cognito identity id and session credentials if those aren't cached (handled by the provider itself). Based on the stack trace, you call getCredProvider(Context context) on the main thread. And refresh() is invoked on the main thread. That's why you see NetworkOnMainThreadException. To fix this issue, you can remove sCredProvider.refresh(). If for some reason you want to call refresh(), you need to call it in a background thread. Please refer to AsyncTask.
I had my environment setup on a previous machine, and I'm on a differnt MacBook. For some strange reason, I keep getting an issue with one of my classes which exend FragmentActivity. It keeps saying it can't find the FragmentActivity class, although I have the support jar in my class path, as per the image:
The detailed error message that I'm seeing is here:

Is there someting else i'm missing?
In your IDE (as shown in your screenshot), check the 'export' box next to the classpath entry that contains the missing class.
I had a similar problem with a class from the Android Support library (Unable to resolve superclass of Lcom ... PagerAdapter). It turned out a library referenced in the .classpath needed to be exported:
From:
<classpathentry
To:
<classpathentry exported="true" ...
For Eclipse users, I fixed the problem by exporting Android Private Libraries in the Java Build Path menu.
