I see the description of "Disable" and "Force Stop" operations on Android devices for apps as:
Force stop will temporarily stop the app from running in the background. The app will start running again as soon as you open it next time whereas Disable will close the application from the phone and you will not be able to use the application again unless you enable it again from settings
But why do disabled apps have an option "Force Stop"? They should not be running as per above definition and there should be nothing to stop.
That behaviour is even observed after a phone restart.
Moreover, "Force Stop" is not available for all disabled apps.
I'm not getting notification when user swipe the app from recent. I've notice that behavior occurs in some specific device for instance I've tested it on nexus devices and HTC devices it's working fine but when user swipe the app from the recent in huawei and some samsung devices it doesn't show notification. I mean i don't get onMessageReceived() callback
After some research I found out that in these devices when user swipe it from recent it force stop the app (the process is completely killed) and I don't get any notification. In huawei they have protected and unprotected apps and if I add the app in protected list from the setting, I start getting notification because i this case it doesn't force stop the app. and I believe in samsung they have the same thing with blacklist and whitelist apps.
I've also tried some solutions like restart the service onTaskRemoved() callbacks or make your app START_STICKY. I've also tried WakefulBroadcastReceiver but nothing is working for me.
So my question is how can i get notification even if it gets forced stop, like it's happening when swiping app from recent.
An old question, but I think it’s important to know that HUAWEI has a feature called “power-intensive app monitor “. It kills every app that runs in the background for a long time unless user gives special permissions to it.
The path to do this:
Settings -> Security & privacy -> Location services -> recent location requests: YOUR APP NAME -> Battery -> uncheck Power-intensive prompt, App launch: Manage manually: check all three positions: Auto-launch, secondary launch, run in background.
I don’t know if there's a way to do this programmatically. I think the best way is to create a sort of help activity and explain the user what to do if application won’t work.
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. My expectation is:
To set "allow permission" in auto start manager during our app install or at the time of app opening.
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
It would be nice a library / class to detect most common "task killers" (preinstalled or not) and letting user know that they need to disable them (and why) to let some feature work, like beacon detection.
For this question, how to disable google asking regularly checking app, there are answers like "uncheck the option Settings > Security > Verify apps". However, on Lollipop I am using, there is no such an option, instead there is an option "Unknown sources".
I unchecked this "Unknown sources", and I could have my app installed. I was asked if "google can regularly check installed apps for potentially harmful behavior". I clicked allow (by mistake). Then I can not start my application. Every time I click my app to start it, it is going to run, but immediately, it is stopped by google.
Do you know where can I configure the android to allow my app to run?
Thanks a lot in advance!

Don't use settings.
On your device, open the Google Settings app(not android settings app);
Touch Security.
Move the switch next to "Improve harmful app detection" on or off.
Okay, I'm pretty sure that this is not possible but a client had asked me to do so in one of our Android application we developed for her.
What she had wanted is that if our application is running, and user navigate to:
Settings > Manage Application > [Our Application]
, the button for "Force Stop" is disabled.
Is this possible? If it is possible, could someone point me out which way I should walk, or if it is not possible, how, using a valid argument based on facts, should I break the news to her.
Update:
She just sent me a screenshot that, in her opinion, validates her request that there's an Android application that disables "Force Stop" button. How am I supposed to explain this to her?
How to disable the "Force Stop" button
Short answer: Use the Device Administration API.
How to explain this to my client?
Show this to your client. It is a nice slideshow providing an easy-to-understand overview of the Device Administration API and its uses.
How do I demonstrate that it works?
Yes, back to your job. Use the API link provided above and the Api Demos included in Google's sample
collection to figure out how to integrate this into your app.
Build the demo and run it on your device.
Choose API Demos->App->Device Admin->General->Enable admin.
Choose Activate once the Device Administration API prompts you with its enabling screen.
Exit the app and attempt to manage the app via your device's settings menu (specifics for this step varies by device).
When viewing the Api Demo's "app info" screen, you should see both Force Stop and Uninstall are disabled.
How do I do this in my own app?
Review DeviceAdminSample.java in the Api Demos app for inspiration. You will need the following:
The following code is what brings up the activation screen:
// Launch the activity to have the user enable our admin.
Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mDeviceAdminSample);
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,
mActivity.getString(R.string.add_admin_extra_app_text));
startActivityForResult(intent, REQUEST_CODE_ENABLE_ADMIN);
However, there are a few other pieces you will need to get this to work:
A broadcast receiver that derives from DeviceAdminReceiver.
Entries in your manifest file that refer to the above broadcast receiver.
Permissions in your manifest for using the Device Administrator API.
An xml file stating what policies your app can access.
All of this can be found in the above links. Good luck with your client!
This is not remotely possible, for great reason.
You should tell her that making this possible would be a huge security disaster. Imagine what would happen if you could create apps which just ate at your processor time by holding a wake lock, and you couldn't kill them. This would be horrible.
In general, if you're wondering if you can modify the "extra-app" behavior of the device, the answer is usually *no*. You should take the viewpoint that nothing on the device is yours to control besides your app and (to a limited extent) the resources to which you're granted access.
No other app has this kind of control, so it's not reasonable to expect that your client's would either. However, the fact that she's asking for this control usually implies something else: that they are worried the user will stop the app and then something bad will happen (the locations will stop being synced, data will stop being sent out to the net, etc...). This would imply that you should look into improving the resilience of the app to different situations. Remember, your app can even be killed off at any time by Android (for example, in the case of low memory).
I think the device screen shot has confused us. Even I can show my application that is installed on the device and the "Force Stop" button is disabled. Where as I have not done any thing specific to that.
The reason of the "Force Stop" button being disabled is, that particular application is NOT running currently. Hence there is not meaning in having the button enabled.
#Rhama you can ask your client to start the application once, press the home button of the device, and goto the settings and see. Surely the "Force Stop" button will be enabled this time.

From ICS, disabling Force stop is possible. If your app has an active device admin then the framework will not allow user to kill the process
Hey I think it is quite possible to disable the "Force Stop" button...check Kaspersky
Parental Control from the market it is doing the same.
Its service is running in the background then also the force stop button is disabled.
The application service is running in background
you can disable the forcestop when the app has admin rights. but soon as those admin rights are revoked then it is back to normal. however in android 4, an application called applock (domobile) was able to prevent that by asking a password when you tried to change admin rights. It could only be done by installing an extra program that applock asked you to. And I guess this might even be seen as a security flaw, infact it no longer works in Android 5.
