In my application i need to have list of images that are downloaded from whatsapp.
I am a newbie in android programing world.
please give me some guide line for it.
There you can follow some steps :
check that whether whatsapp installed or not
if installed then check in which directory it keeps its downloaded image.
if it is a separate folder & can be accessible from outside of that app then you can normally use that images.
if it downloaded its image in a common directory then then it's not possible to find out which images are downloaded by whatsapp.
Thank you.

(How) Is it possible to extract the sql-file from an android application on my pc? We developed an app and used it on some devices but unfortunately some of them didn't save the information on our web interface. So we need the database from three phones and typing by hand is out of the question.
Yes, depending on where it is saved you can access the .db file via the device file explorer on the right in Android Studio.
I assume it is in data/data/yourPackageName/databases
There should be .db files, but again, they could be somewhere else depending on the way you created it.

I'm a beginner in android atudio, I recently make my first app, I put in many raw resources file(txt,mp3) that is why it's size is big (~200Mo).
I want to allow user to download what he need in order to benefit my service like listen to mp3 read text.
You should carefully consider why you need this much data in your app, remove all unnecessary parts and put everything you really need into the .apk as resource.
If I find some app is downloading 200MB to my phone, I'll uninstall that immediately.

I have created an android application in which I want to add a feature for viewing ppts without he user having to download it first. As in, opening a ppt on the phone browser. Any help?
Can you elaborate better.
if what you mean is what i am thinking.
Maybe for a user to be able to view ppt files in your app.
Try using APIs, or ppt supported sdks. refer here

I want to create a simple app for android. I want it to install an .xml file to another apps existing directory when the user runs the app and clicks the install button. It is a patch for an existing app. I have created the .xml file but I want to make it easy for users to patch their app. Seeing as my Android knowledge is limited, I was wondering if I could get some help with this. I'm sure it's simple. Any help is appreciated, thank you.
Unfortunately this is not possible, at least without rooting the device and running your app as root.
This is so by necessity - think what would happen if any application could modify other apps files.

I want user to use my pdf viewer instead of using OS suggested list of viwer(s). Is there is any chance i can achieve this functionality.
I have secure folder where there are pdf files. What ia m looking for is when user opens that folder at that time only my pdf viewer should be used.
Thanks to the FSM you can't. There is no reason for you to take this freedom from end user.
If you need such a requirement, create a viewer application from scratch and asociate it to your own, newly created file extension.
