I did not find answer for my question in the Internet that why want ask here. Theoretical question preparing for creating new Android app:
1) Purpose: create app thats logs events on device and saves it or on device or on server(optional). Logs like: application runs, errors, or traffic rate etc...
Also app can be used for monitoring if some one used your device.
2) Requirements: running in background like service but invisible for user or with minimum visibility.
Question: how to make app with minimum visibility? How set app to be invisible in app list or services list?

I'm developing an app that aims to monitor the usage time of apps and their type.
and I'm having difficulty finding the solution to know which application is open to the user at certain times...
I would like to know if there is any way to apply this...
example in practice:
my monitor app is always running in the background, and it has some alarms that go off at certain times of the day and raises a broadcast. at that moment that my broadcast that got up I would like to put some code snippet that shows which application at that moment is active for the user, for example if at that moment the instagram is being displayed, I want my app to find its package on the device which would be: com.instagram.android or if it was facebook it would find the package com.facebook.katana
technically I'm building an app that will be system and with admin privileges, and that won't go to the playstore so if there is any code for it I can implement it.
I find this question a couple places on the web, but never with a good answer. Let me be specific in the questions asked.
I want to build a custom Android ROM which only features one app. This app is not to interact with any hardware (per now). This app will be launched on the start up of the device. No locked-screen. The device will have to restart if the app malfunctions.
A resource told me that you can change the launcher app of the ROM.
-> Does this mean that the home screen, the one which displays all apps on our phones, is merely another app? If so, can you simply change the launcher app as it is stated here? What were to happen if this app fails?
If this is the case, it would solve the entire issue.
If not, how do you go about making this sort of project? It includes
Making an app on AOSP
Refuse users to leave the app or interact with anything else
Making this app part of the boot-up process
Remove locked screen
Make the app a dependency of the OS (to force shutdown if malfunction)
Thanks in advance for any replies
I just found Android have a topic about dedicated devices (formerly called corporate-owned single-use, or COSU) are a subset of company-owned devices that serve a specific purpose. maybe that can meet your requirement.
BTW, After into the sub-topic lock task mode that mentions about set DPC whitelist APPs and the device policy controller (DPC) needs setup by other steps.... FYR~
I want to write an Android App that analyses chats. For each messenger, for each contact, I want to get a list of all messages sent and received (since installing my app). The key thing here, is that I want the list of messages to be in order. My app should support as many messengers as possible. What would be the best way to do this?
I researched and found a few ways to access messengers' messages:
Using accessibility services
(Related: How to read window content (using accessibilityService) and evoking UI using draw over other app permission in Android?)
to read the screen content of other apps that is annotated with accessibility labels
caveats:
the messenger needs to have accessibility implemented correctly
I have to filter which text blobs are relevant
Using NotificationListenerService
to get the content of notifications for received messages
caveats:
only gets content of messages for which there was a notification
except for their time, there is no order of the messages given
taking screenshots and doing optical character recognition
caveats:
probably insane
When I get the messages, I still have to order them. For this, I think, the accessibility services are my best bet as I could use the date information on screen in most messages, and also their position on the screen.
However, there is still an edge case. As I understand it, accessibility services can only see the content currently on the screen. The user might also use another device to chat while the device with the app installed is powered off. Thus, once the device with the app installed is powered on again, the app might not be able to see the old messages written while the device was powered off (until the user scrolls up again).
Are my assumptions correct? Do you know of a better way for my app to read/sort the messages?
I have an Android app that is transparent that monitors for an event and then displays a message and toggles the background between transparent and a translucent red. The app itself is working exactly as I was hoping. The problem is that only the top most app (my app) is active and updating the view. The app displays over a 3rd party app that runs a live video stream. I want the live video stream app to continue to update while my transparent app is on top. Since I have no control over the other app and it doesn't support multi-window approach, I am looking for a different approach or work around to accomplish the same thing.
I have read of people trying to use a system popup based on a service. Does anyone have experience trying to solve a similar problem and found a good approach for designing the app or a work around?
Try to google about Activity lifecycle. When another app comes as the top application (let's say your transparent app) the last playing application goes to onPause until the user bring the last app back to the top again.
The short answer is: what you want is not possible.
any question?
I have an app I'm currently working on based on the HTC Open Sense SDK for android. However my biggest problem is keeping up with the device checker through the Google Play dev console to only allow certain devices to download the app. My biggest reason is that people will rate my app so low on the scale and say it sucks, but the problem is that they don't read the requirements - if you use an Lg G2 to try and launch an app made for an HTC ONE that requires Sense, it's going to crash.
So, how would i go about building a helper class that would check the device's model via build.prop (without needing root privileges) before opening/starting the main activity, and give the user a notification if the device was incapable of launching the app, and with devices that are capable of launching it, just continue the process of opening the app?
