I know that there are many screen locker applications that can replace the current android lock-screen. I want to develop my own screen locker application and I want to find out if there are any tutorials on how to write a software that changes the functionality of the android firmware such as the current lock-screen. I have searched through the internet but I haven't managed to find any good tutorials.
Thanks for your time. Any help is really appreciated.
I have found a lot of useful information into the presentation of marakana group. Here is a link to the lecture that consists of two parts. In these lectures basics around android platform development are explained.

I am designing a kids learning and gaming application, and I want to have a parent application too for this. Is it possible that I can monitor for how much time my child has used the app, at what time of the day, turn the application off or on for the child, and also see his performance on different learning modules of app. ? Can someone give me idea of how to accomplish it?
Yes this would "technically" be possibly. However, I think your approach to this is flawed. For starters I would use StackOverflow for more technical based questions about specific issues you'll run into when building the app. As far as "can someone give me idea of how to accomplish it" you'll need to research and watch tutorials on building basic apps and work your way up. It's obvious you had an idea for an app and are passionate about pursuing it or else you wouldn't be asking this question on here. So my advice is to keep researching the basics of app development. Watch a tutorial on android studio and begin familiarizing yourself with app design. Best of luck.
I have seen so many apps that provide auto tapping feature. But they don't provide some specific customization so I decided to create a one. I have seen many tutorials that offers auto tapping, but they are supposed to be used in the same app. But I want to create an auto tapping app that can click on other app's View. I am an intermediate java developer but new to Android studio, so I don't know much about Android APIs. Is there any class or package which can provide this feature. For more clearance, I want to do auto tap, when the color at the specific location on screen, (213, 120) for instance, becomes green.
Thanks in advance!
I am not an expert on the subject, I have experience as a BackEnd developer, I am new to the Android world, just like you I am interested in building an app to automate some farming mechanics in Android games with specific behaviors, so I investigated on the subject and the solution you are looking for is the AccessibilityService API, from Android 8.0 (API level 26) it includes several functionalities to make touches without the need for Root, I leave you links with examples of some open source repos that can guide you.
https://developer.android.com/guide/topics/ui/accessibility/service#continued-gestures (Doc)
https://github.com/nestorm001/AutoClicker (Old and abandoned project, but has the functionality of touches)
https://github.com/pylapp/SmoothClicker (A more mature App but need root, it can be helpful to guide you in how to build the UI)
For the detection in the change of the pixel I still do not have a concrete answer, I keep looking, maybe obtaining a dump of the screen every X time and validate the pixels on that is the way but it is still uncertain if it is the way to go.
Something like How to record screen and take screenshots, using Android API?.
I know that you can get a bitmap dump of the screen if you have the activity, but it's not the case, however some class in the following package may be helpful https://developer.android.com/reference/kotlin/android/graphics/package-summary.
I'm currently working in my own implementation, when I have something to show I will gladly share it.
Hi I have been asked to develop an android app as part of my course. It has been agreed upon that this will be a quiz based app which will make use of graphical animations to provide questions for users to answer.
I have no experience in programming any graphics apart from a few tutorials I have looked at. I am wondering if it is possible to create images in photoshop and then use these as objects that will be manipulated via methods or will all graphics have to be created via coding. Any help in the situation would be greatly appreciated.
Thanks
Use Android Animations.
Since it's a quiz based app, you might be interested in using Card Flip Animations, where on one face of the card you show the question and on the other face, have the answer.
There is also an excellent tutorial by Vogella on Animations.
I'm new in Android and I am planning to develop a post-it card Android app. After editing one card, the user could post it on the screen, so every time a user unlocks his phone he will see a little card posted on the home screen. So are there any materials and resources I can learn to realize that effect? Thanks in advance!!
You can interact with the homescreen through widgets. You can start learning about them here:
http://developer.android.com/guide/topics/appwidgets/index.html
You could also start looking into the 2D graphics framework. Here:
http://developer.android.com/guide/topics/graphics/2d-graphics.html
There are also a lot of tutorials and examples provided by the community, but if you are new to android I think it will be a long way to accomplish what you just mentioned.
i want to make an android application, which gets latest updates from wikipedia website and displays it on android home screen using home widget. You can assume it something like weather widget. But, i am unfortunately unable to get updates from wikipedia. I just saw your thread regarding wikipedia, but I am still stuck in my problem.
Can you please send me any sample code, in which something is being brought from wikipedia into my android application. I would be very grateful to you. Please help me, i really need it....
Thanks
