            QUESTION

            Is it possible to launch an Activity on startup in Android 11?
            Asked 2022-Apr-16 at 23:26

            Tested on Pixel 3a (both emulator and physical device (my used device)) API 30 (11.0).

            Repo: https://github.com/amdreallyfast/AndroidStartOnBootExample

            Goal: I'm trying to launch an android app on startup, but failing.

            Note: I am well aware that this should not be done for apps designed for the general public. This is not that. At the moment, this is just concept exploration for a personal project. The larger goal is to tinker with a used Pixel 3a and turn it into a home utility device. I don't want to start the app manually every time I need to turn it on and would rather have it starting automatically, so I'm trying to find a way to launch the app at startup.

            Also Note: Because this is a project to start on boot, I can't use the debugger for most of this and have to rely on notifications instead to detect progress.

            Progress: I've got a BroadcastReceiver that responds to the BOOT_COMPLETED intent by launching a Service. The service's onCreate(...) function creates a simple intent to start another app (at the moment, just Google Maps, which is readily available without additional software installation).

            I've also got MainActivity, a simple program that has a button that uses an intent to launch the same Service. I use this to compare behavior between starting the service at startup and starting the service from an already-running activity.

            Already tried setting the intent flag Intent.FLAG_ACTIVITY_NEW_TASK.

            Problem: Google Maps does not launch from the service when called during startup. I know that the service's code is correctly set up to launch the map intent because launching the MainActivity and pressing the button will launch the service and then start Google Maps just fine. I also know that the code running on startup got through to the point where it launched the map intent because notifications indicate as such.

            The only difference that I'm noticing between not working and working seems to be the manner in which the service is started.

            Documentation: I found this android docs page: https://developer.android.com/guide/components/activities/background-starts. It says (in part):

            Apps running on Android 10 or higher can start activities only when one or more of the following conditions are met:

            • The app has a visible window, such as an activity in the foreground.

            Why doesn't this start? Am I misunderstanding this? Google Maps most certainly has a visible window, so I am expecting to be able to start it.

            Note: Again, I'm not planning on releasing my app to the general public. This is just for me.

            The larger goal is to tinker with a used Pixel 3a and turn it into a home utility device

            Write a launcher app (i.e., have your activity respond to ACTION_VIEW/CATEGORY_HOME) and set it as your default launcher. It will automatically start when the phone starts, just as your current default launcher does. And, you can put a button or something in your own launcher that launches the real launcher via an explicit Intent.

            This would allow you to skip the on-boot receiver and the service.

            Why doesn't this start?

            You do not qualify for a background activity start.

            Google Maps most certainly has a visible window, so I am expecting to be able to start it.

            First, presumably it does not have a visible window right after boot.

            Second, you are not writing the Google Maps app, and Google Maps is not trying to start an activity from the background. You are writing your own app, and your own app is trying to start an activity from the background. And, since your own app does not have a visible window right after boot, it does not qualify for a background activity start under the "app has a visible window" rule.

            The error is caused due to execution of network request on main thread (a.k.a. UI thread). In general, thread blocking operations (like file read, network requests) are prohibited on main thread. This is done to avoid App Not responding error.

            In your mainActivity.java, since BroadcastReceiver#onReceive is executed on main thread. (Ref: https://stackoverflow.com/a/5676888/5309486 ). And inside this onReceive function, you are trying to make the network request.

            Just, use handler and post the network call to background thread (or any other thread) and that will fix your issue.

            You should check the specifications of the device that is laggy and monitor RAM and CPU usage of the device, before, after and during your app runtime, speatially the RAM usage, maybe Android 30 is putting too much pressure on device and that is causing the issue.

            In General the issue that are seen on some devices and not on another are caused ether by the difference between Android Versions and their resource handling methods or bottleneck between Hardware and Software on same OS version on different devices.

            You can monitor device resource usage ether by Android Studio's own resource monitor tool "Android Profiler" or third party Resource Monitoring Apps found on Google Play.

            If there is a process or function in your App that causing the resource leak you can fix it easily by detecting it from android profiler but if the issue is caused by OS Resource handling or Hardware and Software bottleneck you should skip that device.

            You need to use two distinct, up-to-date PendingIntent objects, wrapped around different Intent objects (e.g., ones with differing extras).

            For "distinct", you need the IDs of the PendingIntent objects to be different. The ID is the second parameter to the PendingIntent.getBroadcast() call.

            For "up-to-date", you need to update any existing PendingIntent that your code might have created previously. For that, pass PendingIntent.FLAG_UPDATE_CURRENT as the fourth parameter to the PendingIntent.getBroadcast() call.

            ANSWER

            Answered 2022-Mar-21 at 12:26

            You are better off launching an Activity directly from the Notification. The Activity could then do the analytics and figure out what Activity needs to be launched and then delegate to that. As an alternative, the launched Activity could send the broadcast Intent to your BroadcastReceiver which could do the work.

            NOTE: If you launch an Activity directly from a Notification, that is not a trampoline. The trampoline occurs when you launch a Service or a BroadcastReceiver directly from the Notification and that component then launches an Activity. The idea is that the user needs to be in control of what pops onto his screen. If he taps a notification, he expects that something will appear on his screen, if your Service launches an Activity, that can happen at any time and could possibly interrupt him.

            You should not use FileProvider to obtain an uri for your file.

            You can get an uri from DownloadManager and use it to serve your file.

            Code would be the same for all Android versions.

            How to get instance on my singleton handler in Broadcast Receiver?
            Asked 2022-Mar-13 at 00:36

            I went down a rabbit hole of trying to make my service work and I believe I have just made an amalgamation. I am trying to make a step counter service, it uses a handler which has a step counter sensor implemented onto it. Every 6 hours i want to update my server with the step count inforrmation, reset the step count near to the end of the day and set another alarm on my handler to do the same action every 6 hours. The handler also routinely sends data to an activity to read the number of steps its recorded.

            However, everything works but I am unable to get an instance of my handler in my broadcast receiver. So another alarm is never set and the steps are never reset. Can anyone help me with this?

            To be specific, the first line of code in the broadcast receiver (StepCounterHandler handler = StepCounterHandler.getInstance();) will always return null from my testing.

            This is my code:

            Answered 2022-Mar-13 at 00:23

            If the zero-parameter getInstance() is returning null, you have no singleton.

            You have two processes. The StepCounterService is in the :stepCounterService process. StepCountUpdaterAlarm is in the default process. These processes share no objects, and so they will have separate StepCounterHandler singleton instances. If you have not done something previously to set up the StepCounterHandler in the default process, it will be null.

            If you are expecting to share the singleton between StepCounterService and StepCountUpdaterAlarm, they will need to be in the same process. Either move StepCountUpdaterAlarm into the :stepCounterService process or move StepCounterService into the default process.
