i dont know how to oberserve other apps processes and how to start another app that wasnt maked by me.
all that i got for now is run it as system service.
another possibility is create a self app that restart it own when it crashes or be closed.

For your question, you can learn the application sandbox.
https://source.android.com/security/app-sandbox
When the developer makes an application, they can define their intent filter and tt is some way to let another application invoke it.
You can uncompress .apk from another application and find out the file AndroidManifest.xml. And then you can try it.
But you can just control the part of door they open to you.

I found some launchers that are able to run installed apps inside their own activity. ( https://play.google.com/store/apps/details?id=com.lwi.android.flapps )
This launcher adds their own functions like maximize, minimize etc. I guess they are creating widgets (because they need drawing over apps permission) and running inside them. But how :)
Can you show me how I can run another android application inside my own activity, widget etc. like this app did ?
Best,

I think the following documentation should help you out with learning how to get your app to interact with other apps: https://developer.android.com/training/basics/intents
Especially interesting to you would be the section on sending the user to another app: https://developer.android.com/training/basics/intents/sending
I want to create an application in Android that will show the devices list of applications and then allow the user to select which apps they want to be restricted access to for a certain period of time.
I am aware there is an Android Application named "AppBlock" but i don't know how this works.
You select the app, the period of time and then it doesn't allow you to open the app.
You cannot actually block start of another application.
The only way that I see it is possible: you need to save the list of applications Info in your app that need to be blocked with the time when it need to be blocked. Implement a service that runs "forever" and detects started applications.
Refer to this answer about how to do it. On each detection you should check if application present in your database and if the time now says it need to be blocked. If it is - close the application. Refer to this answer for learning how to do it.
That is global architecture I think you should follow.
To Build App Block u need the following things
1-Accessibity services (AS)2-Forground Services (FS)
BY AS you will be able to stop activity that you have in your bloker list
FS will alive your application context that help to find block app
I know it's not the best practice, but it is a requested feature (e.g. for business apps). When the App gets installed, I need to automatically place it on the home screen. I saw a lot of code on the internet, but all of the code only works on button click when the app starts. But I need to place a shortcut on the homescreen immediately after the app is installed and before the app starts. Is there a way I can achieve this?
PS: To make the question more clear: The app will be distributed without Google Play Store, so that's not an option.
Thanks for your help!
Best regards,
Robin
You can't run any code in your application before the user starts your application for first time during to restrictions since Android 3.1. Check this for more information
That's an optional feature of the Market app, not of the apps themselves. When designing an application , it does not receive a broadcast about itself being installed.
the first time the app launched can create it.
You can achieve that by creating a method in your main activity and call this method from oncreate and create a boolean variable andsave it in shared preferences
Because I've read that it's bad practice to have your app running at all time, I'm trying to have it start when specific built in apps start. I believe it has something to do with intent and the following link but I don't know where to start.

If this is possible can someone post a code snippet to help me out? I'm wanted my app to start when Media or the camera is accessed and then close when those two apps are closed.
I'm wanted my app to start when Media or the camera is accessed and then close when those two apps are closed.
That is not possible, sorry.
i'm developing an application that need to do certain operations right after the installation (mainly save some configuration parameters).
I want to know if it is possible, and how to do it.
And also, is possible to start the application immediately after the installation (i need to start a BroadCastReceiver)
Thanks,
Ivan
This is not possible. The user has to start the app manually. Once the app has started you can then sit on a boot broadcast (BOOT_COMPLETED) and start services in the background from then on, but the first time the app starts needs to be instigated manually.
