I've implemented a short Flutter App which is requesting and checking the camera permission which works as expected. But, when manually changing the camera permission from the app settings, for both Android and iOS, it will restart my app. I need to mention that I've added in AndroidManifest.xml and Info.plist the required keys for camera. One interesting thing is that for the location the behaviour is fine and the app does not get restarted.
For permissions I'm using the permission_handler flutter library.
I don't know if is a flutter issue or a general mobile known behaviour but if someone knows more please let me know. If someone need some code example I can also provide this. Thank you.
It doesn't get 'restarted', it gets killed. Meaning, it will run from app launch the next time. This is because some permission settings cannot be changed while the App is running. This is by design.

I am using Delphi 11.2 and the call phone function on android does not works anymore. When I start the app it's stop to working. Using the Delphi samples PhoneDialer project the same error.
Any idea ?
Regards.
Although it's trivial, I think it may be best to document it as an answer.
Many of the resources on the phone require that the user grants permission for using them. The purpose of this mechanism is to stop viruses and badly behaved applications from running without the user's knowledge.
Phone is such a resource. You will need to grant your app permission to use it. It is not enough that your app checks if it has been granted or if you have registered the PhoneDialerService.
Flutter app crashes when user manually changing location perimssion from allow to deny. Is this a normal behavior ?, i've tried to change manually the permissions of other popular apps, they all restart and not crash. But my app after changing permission says Lost Connection to Device and thats it
Actually this is a normal behavior on debugging mode , once you change app permission from settings it automatically kills the app and you have to re run it in order for the new settings to take effect
for more info you can read this GitHub issue discussion

I have the following problem:
My app is distributed over an MDM system and runs in Android for Work.
In certain situation, the app must temporarily terminate the DnD mode. To achieve this, the user must grant the DnD permission when the app is started.
So far so good. If I install the app in the unmanaged area, the app shows up in the list and the permission can be granted without any problems.
As soon as the app is distributed via an MDM system, the app no longer appears in the list and the permission cannot be granted. All authorizations have been granted in the MDM system. As an example, I have distributed the Google App over the MDM system. This app appears in the list.
In the Manifest I have set the following permission:
<uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY" />
When the app is started, the following code is executed:
NotificationManager nm = (NotificationManager).getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M && !nm.isNotificationPolicyAccessGranted()) {
Intent intent = new
Intent(Settings.ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS);
startActivity(intent);
}
The problem only occurs with DnD permission. All other permissions such as overlay permission, are displayed without problems.
I hope anyone can help me.
According to Android documentation: NOT POSSIBLE
Users can grant and deny access to Do Not Disturb configuration from here. Managed profiles cannot grant Do Not Disturb access.
I haven't found a proper solution for the problem yet but I found a workaround to display the app in the work area. It seems that the app is only displayed in the dialog if the same app is also installed in the private area.
If the app is not installed in the private area, it will also not appear in the work area.
My workaround was to install the app in the private and work area. After the permission in the work area was granted, I removed the app from the private area. Like I said, it's not a solution to the problem itself, but it worked.
To me this looks like a bug in Android, because for all other permissions the app appears in the list
Apparently there is issure reported regarding this on Google Issue Tracker
https://issuetracker.google.com/issues/77939714
This is the reply from Google:
Status: Won't Fix (Intended Behavior) 11:41AM You can not change DND
settings from a managed profile app. We will be updating the
documentation to clarify this.
There is also a reply stating:
Microsoft Intune has released their fully managed Android Enterprise
profile setup for Android Devices. ... and it can now access and
grant the DnD permission. Not sure if its the fact that we have gone
to fully managed devices or if something else has changed.
And I would believe this is actually because the device is fully managed.
So according to my understadning there are two options:
Fully managed device (will require a factory reset on the phone)
Install it on the personal profile
We have the same issue with the app SignOnSite. Can't get access to the DnD function for emergency evacuations unless we also install the app in the Personal space as well. Makes it to risky doing it this way, so ended up just installing the app in the Personal space.
Using Intune for our MDM.
Try this -
Intent intent = new Intent("android.settings.NOTIFICATION_POLICY_ACCESS_SETTINGS");
startActivity(intent);
i am working on an app using the App Ops Manager. I want to get access to the Logs and analyze which app used which resource. The app works fine for the moment, since a wanted to deplay a Demo version. I have the following problem:
I started the App from Android Studio all the time and granted the Permission "GET_APP_OPS_STATS" manually by using adb.exe. Now ive wrote it down in the AndroidManifest.xml by simply using
<uses-permission android:name="android.permission.GET_APP_OPS_STATS" />
This permission doesnt work in the app and I dont get asked to set it manually (like the one for accessing the storage). I think this could be caused by the permission itself, which could be a system permission.
Are there any solutions, how i can use the App Ops Logs without rooting my device od using third party software? Maybe there is another permission i have to set or some code that sets /asks for the permission.
Best regards,
Marvin
I'd like to know if there is any way to determine the permissions my app needs.
There is a similar question here:How do I determine why my Android app requires certain permissions?
But the answer states, that you basically have to find out yourself and I can't believe this.
Is there really no way to tell Eclipse to take a look at my code and determine the needed permissions or something like this? There should be no problem to automate this.
Or is there a way to test permissions on a device. When I install my app on my local device I'm not asked for any permissions.
Any help is really welcome.
This should work:
boolean crashes = true
while (crashes) {
ReadLogCat()
AddPermissionFoundMissingAccordingToLogCat()
crashes = TryAgain()
}
PS: This is pseudocode ;)
PPS: You didn't copy this to Eclipse, did you? Just kiddin' ;)
Believe it.
The app crashes and tells you the reason why: it expected some permission(s) declared in its manifest file.
It normally tells you in 2 ways: in a Dialog (FC Dialog) and in the LogCat.
You have to define permissions according to what your apps doing, if it's accessing the internet, it needs permission to do it. If it wants to locate you via GPS, it needs a permission for it and no you can't automate it, not officially anyway.
Think your app as a virtual child, you need to grant it permission to do stuff or else it won't do anything. So you have to pretty much decide yourself.
But you need not worry, if you're missing a permission, the log will let you know which one it is.
well i won't consider this as official solution for this problem
usually when i miss any permission in my application say i am using internet connectivity or get tasks but i didn't declared them in manifest
when i run my app i get it in log cat saying internet permission and get tasks permissions are required for this app to run
hope that answer your question
Is there really no way to tell Eclipse to take a look at my code and determine the needed permissions or something like this?
If you have a test suite that adequately tests your app, running the test suite will tell you the needed permissions, because your tests will crash if you do not have them.
Or is there a way to test permissions on a device. When I install my app on my local device I'm not asked for any permissions.
The permissions that you see on install are based on your <uses-permission> elements in your manifest, not some analysis of the app beyond that. Hence, this will not help you. That being said, installing your app by any means other than adb, such as downloading the app from a Web server, will pop up the permissions dialog, so you can see what prospective users will see at install time.
