How to integrate Push sharp for Android GCM (Pushnotification)?

I am referring this link to implement push sharp in android,
https://github.com/Redth/PushSharp#monotouch-and-mono-for-android-client-application-integration
But given code is in .cs,
So please suggest how to use this library in android,share any kind of documentation regarding this.
Thanks in advance.

Well, the link you supplied suggests that this library works with MonoTouch and Mono for Android. I'm not familiar with those, but you don't have to use them for your client side (even if you use PushSharp in your server).
You can simply use the code samples in the GCM developer guide (which are all in Java).

Push notification on android: IBM MQTT

I am very new to android environment and have to set up client side using the (wmqtt.jar) sample application given on http://www-01.ibm.com/support/docview.wss?
I know only about hello world program.
Kindly tell how can I integrate it in my simple android application, step by step.
Thanks and Regards.

There is a good example and run through at http://dalelane.co.uk/blog/?p=1599
I'd also point out that you might be better off with the recently released open source Java client. You can find it at http://git.eclipse.org/c/paho/org.eclipse.paho.mqtt.java.git/ - you should find the licence is much friendlier than for wmqtt.jar.

As Roger says, the best / latest Java client code is that available from the Eclipse Paho project - http://git.eclipse.org/c/paho/org.eclipse.paho.mqtt.java.git/
The IA92 code and wmqtt.jar has a difficult license and does not support some of the latest features like authentication.
In addition, you will find a lot of useful links and information on the mqtt.org wiki http://mqtt.org/wiki/doku.php/mqtt_on_the_android_platform

Very good sample code available at http://mosquitto.org/files/examples/android-mqtt-example.zip. Once you understand how it works, you would be able to move to writing your own code.

Android NDK tutorials?

Are there any decent Android NDK examples and tutorials out there? Where can I find them? If there are any geared more specifically towards game engine development (as I am looking to convert mine over to android) that would be most helpful.

There was a blog post a while about android game programming on the official blog. Also Quake was ported to Android using a mix of Java and Native code and has been open sourced. Not sure how good it is from a tutorial standpoint but looking at real code always helps me more than following a basic tutorial.

Here is one complete documentation.

Google Document Sample with google-api-java-client in Android

I am making a simple apps for Android, This apps have some function:
- Upload
- Download
- ShowAllFile
When i use Gdata, it's easy to make this function in Java
But Gdata didn't support Android.
Can anyone give sample code for GoogleDoc in Android which use google-api-java-clien ?
Best Regards
P/s: UPDATE: i can upload file

You should have a look at http://samples.google-api-java-client.googlecode.com/hg/picasa-atom-android-sample/instructions.html?r=default. This is a sample for Picasa, but GDoc is much the same.

Of course G-Data is supported in Android
On there you will find samples and a video with a presentation on how to access G-Data API on Android
