Hide permission popup in android M/N - android

Is there any way in Android M/N to hide the permission popup .
I completely understands that Android M onwards it has a new security modal and it mandates run time permissions check for dangerous permissions. But I did not find anything related to hide/suppress the popup.
After reading the material on developer documentation(link below) I found that only normal permission can be pre granted by System without asking from user. But for others e.g. Camera, Network, Media files etc. we MUST get permission from user which I'm trying to avoid for better user experience.
https://developer.android.com/guide/topics/security/permissions.html#normal-dangerous
All I'm trying to understand that is there any way to create an app with higher privilege or make modification in AOSP or anything we can do to suppress the permission popup in Android M or N?
Any help would be appreciated. Thanks!

Only with root permissions.
Runtime.getRuntime().exec("su -c \"pm grant com.example.app android.permission.ACCESS_FINE_LOCATION\"");

Huawei Android devices - properly requesting permissions for background locations

We develop an application which requires several permissions in order to get the user’s location while in the background.
We are having problems requesting the required permissions on Huawei devices. It seems that in addition to location permission and white listing the app from battery optimizations, an additional step is required in order to disable battery optimizations and enable auto launching:
The problem is we found no way of automatically requesting permission from the user, and the only way we found is having the user manually go to these screens and change the settings.
We did find a shortcut to take us “half way”, to the application settings:
Intent intent = new
Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
intent.setData(Uri.parse("package:"+context.getPackageName()));
But multiple non intuitive actions are still required from the user.
Our aim:
We would very much like to make the process easier for the user. Optimally, to have a system dialog appear which asks the user for the permissions, instead of having him manually change the settings, much like the whitelisting of normal Android devices:
Is it possible using a Huawei specific SDK extension?
If (1) is not possible, at the very least we need a way to know if the user changes these settings or not. Currently we don’t know and cannot inform the user if the application works properly or not!
Are you expecting that your app displays a permission popup so that users can easily assign related permissions to your app?
If yes, you can integrate HMS Core Location Kit into your app. Before performing an operation requiring a permission, your app dynamically checks its permissions.
If your app does not have the required permission, it will display a popup to prompt the user to assign the permission. You can implement the popup with few code lines and users can easily assign permissions in the popup. For details, visit https://developer.huawei.com/consumer/en/doc/development/HMS-Guides/location-guidev4.
In addition to dynamic authorization, do not forget to apply for static permissions in the Manifest file.

Android Do not Disturb (DnD) permission in managed profile

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 cannot grant the following permission on my app..Kindly suggest any alternative?

<uses-permission android:name="android.permission.CALL_PRIVILEGED"/>
I cannot grant this permission in the android manifest file as it shows the following
error:
Permissions with the protection level signature or signatureOrSystem are only granted to system apps. If an app is a regular non-system app, it will never be able to use these permissions.
So,what should i do now?

If your app is expected to run on non-rooted devices, then you're simply doomed - you can do nothing, unless you have platform keys to sign your app with it.
Alternatively, you may narrow your audience to rooted devices only but that would allow you to do what you want incl. using features usually reserved for the platform or system apps ony.
Finally you may rethink your approach. Perhaps what you want to do can be achieved other way, w/o need of elevating app privileges.
For this "CALL_PRIVILEGED" permission , you will need a rooted device and the app must be installed as a system app only.
From the documentation (https://developer.android.com/reference/android/Manifest.permission.html#CALL_PRIVILEGED):
String CALL_PRIVILEGED
Allows an application to call any phone number, including emergency numbers,
without going through the Dialer user interface for the user to confirm the
call being placed.
Not for use by third-party applications.
So, the short answer is that you can't use it. What are you trying to accomplish?

Android M Permission list not showing for manual install

Android M not showing normal permission like Internet, WIFI in the permission list. Its just saying No special permission to display. Is that how Android M will display permission, it will never show permission prior to install. Can any one experienced this before.
attached screenshot,please check it.
Please help me to finding this answer.
Thanks.
Quoting the documentation:
When the user installs or updates the app, the system grants the app all permissions listed in the manifest that fall under PROTECTION_NORMAL. For example, alarm clock and internet permissions fall under PROTECTION_NORMAL, so they are automatically granted at install time. For more information about how normal permissions are handled, see Normal Permissions.
The system may also grant the app signature permissions, as described in System components and signature permissions. The user is not prompted to grant any permissions at install time.

Security Exception: Permission denial for DEVICE_POWER

I am trying to write a simple android app that switches off my phone screen. When I am runnning this app I get Security Exception: Permission denial app requires android.permission.DEVICE_POWER. I know that this is a protected permission but my phone is rooted. What do I specify that I can use this permission? I have already tried declaring DEVICE_ADMIN permssion along with the DEVICE_POWER permission but it still doesn't work.
Rooting potentially lets you circumvent or modify the android security model, but it doesn't necessarily mean you get special privileges for an android API which enforces it. You cannot ordinarily run an application itself as root, while code in a helper executable which you could start as root will have substantial difficulty interacting with the Android APIs.
What you are trying to do may really not be a very good idea. But if you really want to do it, you would need to either install your own build of Android so that you have a (self generated) key matching that which you used to sign the platform, which you can then use to sign your application, or else try to install your application on the system partition.
If all you want to do is turn the screen off, then why don't you use the PowerManager? According to the documentation, the goToSleep() function will force the device to go to sleep.
