Admob Ads with Python Subset For Android (PGS4A)

I'd like to have advertisements in an android App I've written and built using PGS4A. I've done my research and all, but there doesn't seem to be any online resources that explains how to do that just yet. I haven't much knowledge on Java either, which is clearly why I've written that in Python. Has anyone found a way to achieve that? If not, how difficult would it be to convert the project files into an Android Studio (or even an Eclipse) project? (so then one can just implement the ads following the Java Admob documentation found everywhere)
Thank you in advance.

To access Java already implemented version you can use pyjnius. I tried to use it for something else and I didn't succeed. Well, I yielded pretty quickly because it wasn't necessary for my project.
Otherwise, I am afraid, you will have to implement it yourself from scratch.
I never heard about a finished solution for your problem.
If you succeeded to use PGU, it wouldn't be so hard.
If not, well, I wish you luck, and put your solution online for others.
There is an Eclipse plug-in for Python. I think that Android studio does not support PGS4A. Never needed it. Console is the queen.

LaunchingAndroid application from Android browser / Chrome - phonegap

I'm working on a project and I want to implement qr-code scanner in it.
I tried to look for an in-app solution but i didn't find anything relevant so i decided to use a common bar-code scanner to launch an url.
When the user tries to open this link, I want Android to show him a chooser dialog where he can choose to open that link using my application.
I saw a lot of answer to a question like this, but i didn't find anyting about implementing this thing in a no-native android application.
The application is made in html5+javascript+php and all the answers i found spoke abount intent and so on...there is a way to implement the same feature using html5?
Thank you,
Christian

here is the perfect link -

Even I am new to cordova and found many difficulties while designing my 1st plugin.
and be careful cordova 3.0 and later version of cordova has huge difference with the earlier version.

Using Sphinx4 on Android

I am really new to the java & android apps development. Currently I'm doing a prototype application about the voice recognition. Which use the sphinx4 speech recognition. I'm really no idea that, is that Sphinx4 can be used on the android SDK?
Using Sphinx4.0 to build a speech recog. Android application (this shows that, it can't)
https://sourceforge.net/p/cmusphinx/discussion/sphinx4/thread/ce6ee093/ (But this said it can.)
if yes, i really no idea how to make use of the sphinx4, anyone can kindly provide the guide for me to complete the prototype?
Thanks for your kindly help.

It is possible to run Sphinx4 on android, however, you need to remove sphinx4 parts that use desktop-specific java api like java sound API. You still can have the core in place and demo should work as expected.
You need to reimplement Microphone class to use android API for sound input.
For more details see the discussion about that:
https://sourceforge.net/p/cmusphinx/mailman/message/31317160/
So it is some work and it requires coding skills. If you don't have that, use pocketsphinx instead like Opiatefuchs suggests you. It's well documented approach which requires minimum efforts.

I also tried to do some App with Pocketsphinx, not Sphinx4. I think this is really not designed for android, but maybe You could get it work. But for which reason? PocketSphinx is a good designed API for including in Android. I had mad some tutorial on my website for how to get the Pocketsphinx work, I advise to stop thinking about Sphinx4 because it would be a heavy coding thing to get it work. PocketSpinx has all You need...look at my Tutorial, this is a better way:
https://sites.google.com/site/opiatefuchs/home/pocketsphinxandroiddemo
Until now I stopped working on it, but when I got time, I will start to include Pocketsphix into an apk. But this tut only shows how to get the example demo work and set up Your runtime environment to work with Pocketsphinx.

Does android support video cropping?

i need to implement crop operation over a Video,is there any builtin class or third party library available or is there any alternate approach. I already had a walkthrough from android developer to Mr.Google !

As far as I know android has no built in API's for those video manipulations. I recommend FFMPEG. Go through this tutorial once. I have used xuggler with java swing. It served well and I think it might help you.

Developing Android outside of the SDK

It seems as if every Android application I really want to make is impossible to make with the current SDK. It doesn't give me access to certain things I would like to work with. This is an example of one of these things.
I know it is possible since I've seen apps in the market that do things that the SDK cannot do. My basic question is can someone point me in the direction of how to create such an application. I've searched around, but all of the links I've found are for developing with the SDK. A simple link to a tutorial that can show me how to access Android elements that aren't available through the SDK would be great.
Thanks.

You will not find a tutorial on it because the NDK is in flux..
What I have found is ..
One of the Eclipse CDT has blog posts on how to setup NDK projects in Eclipse.
The people who know Android Embedded C and frameworks are usually on certain IRc channel.
Plenty of code documentation..
Google search for android jni wrapper blog posts.
But keep this in mind several areas require state management as hey interact with hardware buffers in a certain way..ie audio..video..etc.
