I was thinking to build up an app to manage the notifications. I gave a look to the Notification Manager but i didn't find anything that could help me. I'd like to get all the notifications (that are in the notification bar). Have you got any idea? Thanks, regards.
I don't believe there's any possibility to do such thing using the public API. There are strict restrictions to what an app can access, for obvious security reasons. Each app is handled as a different user by the OS, so it has access only to public data and to the data owned by that app.
If you need this for a private project, you may consider modifying the android source code. I can't give you many details on how to do it, but I would start by looking at com.android.server.NotificationManagerService (source code here).

I am a beginner in android development. I want to know that is it possible to know the app which is opened currently. I came to know that finding the apps which are running currently through Activity Manager (getRunningTasks()) is now removed from the Android studio. So I want to know is there any other way to know? I just want to know the app which is opened and running currently on the mobile but not the apps running in the background Could somebody please help me in this case?
You can use AccessibilityService to get event notification. But AccessibilityService are specifically for accessibility uses. If you use the service for other purposes, then the application will more likely to be downed/removed for PlayStore due to policies. Another viable option is UsageStatsManager, but with some limitations.
UsageStatsManager is not push event based system. You have to poll in few mills(depends upon the use-case)
Usage Access Permission grant/deny is not straight forward. You have to start Setting Activity with Settings#ACTION_USAGE_ACCESS_SETTINGS action and have to rely on the users understanding of how to grant permission(Since permission list may contain other applications).
I was wondering if anyone had a relatively simple solution for us.
We created an app to be used by our clients on android devices that we give them.
We would like the client to only be able to use our app and have limited access to everything else (i.e. settings, email etc.) What is the best way to achieve this without using 3rd party apps.
Thank you in advance!
This may not help but the L preview has a task locking feature included that may be of some insight, I'm not aware of how it functions as yet
Task locking
The L Developer Preview introduces a new task locking API that lets you temporarily restrict users from leaving your app or being interrupted by notifications. This could be used, for example, if you are developing an education app to support high stakes assessment requirements on Android. Once your app activates this mode, users will not be able to see notifications, access other apps, or return to the Home screen, until your app exits the mode.

Is it possible to get the user behavior on the phone (for example Alpesh has an Android phone and he uses multiple apps, browser YouTube etc). Whatever he is doing on the phone I want to get all those things from behind (which apps he has installed, which app he opens and what he search on the phone, All these data I want to get programmatically so what all can be get in android).
For now I am aware that installed apps list can be get easily but I want to get usage history and what he do all on mobile.
This is not a code solution, but an answer to your question, so you can get start some where.
In my opinion your question title are asking about two things.
(part 1) Getting User Behavior on the Android Phone (part 2)(App History, Browse
History etc)
1- First part Getting User Behavior on the Android Phone:
There is a concept called context awareness. Short described; it is about gathering different information from the phone, like light sensor, motion sensor, sound, location or even user behavior etc. and depending on your app requirement and the gathered information:
You could send these information over cloud data store for statically usage
You could make your phone doing (behavior) different things depending on location, motion or what ever.
etc.
For context awareness it is an open area for pervasive computing research. And it is not just few lines of code to write, it is typically a complete solution depending on requirement. Example I have built a context awareness application to gather noise collected by phones from different locations for research purpose inspired from this framework, but I am pretty sure you can find other frameworks or even build your own, as I did in my case.
The mentioned framework has some examples.
2- The second part is about App History, Browse History etc.:
This is possible, but you still need to build a peace of software (App) to collect all these information (logs) from the phone. Hereafter you can make phone act on different conditions and/or again send it over a RESTful API over cloud service data store, there is no limit for it.
The problem is, there is no thing out of the box for your requirement. Even if you find frameworks you still need to research it and further work on it.
You can find different examples for your requirement, like to collect browser history, you can find SO question here:
Get browser history and search result in android
Or get list of installed application:
How to get a list of installed android applications and pick one to run
My point here is you need to solve small goals at a time and put your knowledge together at the end.
Both 1 and 2 can also be related to each other, depending on your achievement.
Conclusion
Make a goal to your project.
Define the main requirements and tasks of your project.
Research your options (Technology, Cost, Target Audience, What data I can or I should not collect, what is possible to collect, what is the limits, Privacy issues etc.).
Split your project in small assets and try to solve small problems/goals.
Finally you would be able to put the puzzles together and build your final application
but i want to get usage history and what he do all on mobile
This is not possible and shouldn't ever be possible. Each app is sandboxed by Android so apps cannot inspect what other apps are doing. Think about it, you wouldn't want apps to be able to intercept private information such as banking details.
Every app is isolated from the other ones. Unless you develop a system signed app, you will not be able to gather all that data.
What you could do is to develop your own Android Rom where you then develop your data collection the exact way you want. Then you need to distribute your rom, which is another story...
I'm having quite tough problem while developing a testing framework for android apps. The text got a bit long so the actual question is in bold for those that don't want to read the context.
Basically, what I'd like to achieve right now is to trace user activity while he's using the application as one of the features. There's my app that manages context data all the time and developer's app - the one being tested. My idea to do this was to get coordinates where user touched the screen along with taking a screenshot simultaneously. Then I'd use the coordinates to mark the spot on the screenshot to get the idea of what user was doing the whole time with the app. Take hints on user experience and trace crashes.
Non-system apps cannot take a screenshot for security reasons, but application itself can take a screenshot of its Activities without much trouble for non-rooted users, e.g. like here. My only hope here is to interfere with developers' code to implement the functionality of doing so while my testing app is running. Each Activity then would have to extend my overridden Activity instead of regular one, implement an interface, implement broadcast receiver etc.
I am going to write a library for developer who would like his app to be tested with my framework. I'd like it to do the job for me and be as non-intrusive as it's possible for him to use. How to achieve that the best way?
Ideal case would assume linking the library to project with maybe a small addition in manifest that'd get the job done and after just unlinking, removing that bit of xml in manifest for production.
That's an open question. I don't expect any bits of code, but some nifty Java trick, Android OS functionality or even completely other approach that'd solve my problem
I tried to be as clear as possible with the question, but that's a quite tough matter for me to describe so that could have turned out contrary. Don't hesitate to ask me for more details, to speak my mind more clearly or even rewrite the question. Thank you all very much for help!
I created an Android app which communicates via USART with a µC in order to evaluate data. My co-workers and customers should use the tablet for only this purpose now. Is there any possibility to "hide" the Android OS or making it inaccessible?
Devices are rooted and I am willing to build custom ROMs (even though I do not have any experience with that yet). Are there any approaches available that I do not have to start from scratch?
Many thanks for your help.
Well. That what I'm trying to do !
The first thing I tried was to start the app just after the boot of the device (Quite easy with this).
Then, I get Android source code, and I hide the bottom bar using this code
The problem is, if your application is not stable ... you'll have some problem.
If you want to modify Android source code, the developper doc contains a very good tutorial to start !
