android-background

I have a pretty unique issue where I am trying to retrieve previous fragment that was there before I went to the homescreen via the current fragment( last visible fragment) Not to confuse any further, here's the steps to repro my issue 1 ) launch the mainactivity, from there open fragment A via a button click (say button A) 2) from fragment A , press another button ,say B, which will open fragment B. 3) Fragment B has a close and save button , pressing which leads me back to the previous backstack fragment A ( activity.backpressed()) 4) Now, I have a scenario where I am calling fragment B, by

The main objective of my app is, when a button is pressed: Collect data from the sensors Store data in the database Repeat periodically (every X seconds) I want to have it done in background, and if the Main Activity is destroyed, the background progress to be still running. So if you delete the activity, I want it still running. What I am doing right now, is having an AlarmManager with an Intent Service , to set the periodic recording of the Data, but whenever I destroy the Activity , as they are related, my app crashes. I know there are different to run a background process, but none fits in

I am using sticky service for background operations and its working fine in all phones even when app is closed by swiping from stack(then service is restart) but in RedMi Note 3w When app is closed by swiping from stack , service is not restarting .I test Whats App and its working fine on Note 3 so it means WhatsApp is able to manage this so how can we restart Background service getting killed on redmi phone?

I have an application which needs to run in the background, so I'm using a WakeFullService for that. But in Asus Zenfone it's not working because Auto start manager does not allow the app to run.

Is there any API available from ASUS Auto Start Manager which can help me check the permission status of my app so that I can notify the user via normal text alert to turn on the permission. Someone did it for Huawei: "Protected Apps" setting on Huawei phones, and how to handle it

You use ImageView instead of background placing it as the first layout's element and specify android:scaleType attribute for it:
