Android Question Runtime Requests-Auto handling

Is there any way that we will be able to automatically accept a system dialog asking us to either allow or deny a Runtime request on startup?

I am using the USB-port(OTG adapter) as a serial port and i would like the system dialog to always be accepted automatically. An alternative would be to show me how to do the permissions for this.

It is not possible. The device user must accept it based on Google Guidelines.

You, as the deviceuser, can check the Checkbox and then your app will be used always when the OTG device connects. You have to answer it only once then (hopefully). Point is that the device user MUST accept it.

If you use Runtime Permissions (Runtime Permissions (Android 6.0+ Permissions)), the user will only be asked once (assuming they accept). After that your check of that permission will return true & the dialog won't be presented.

I am trying to make a automated unit where no one will be coming close to the device or even able to access it. And if i do check the box the next time it reboots the device will be asking me to allow the app to use the port

Even after i have checked the tick box to set my app as a default the next time it boots the app again asks for a user to accept it

Don't confuse runtime permissions with the USB permission dialog. They are not related.

You should use the XML based permission for USB. It will then only ask the permission once.

Please use [code]code here...[/code] tags when posting code.

Not related but you should remove this:
B4X: 
AddManifestText(<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="23" />
)

Looks correct. Make sure that there isn't any other app that might be registered with the same filter.

I only have the single app running on the android device. So i don't think that there is any apps that would use the same ports.

But thank you to everyone for very fast and helpful replies

Im currently running it on a raspberry pi 3b+. I have tried to make it work on the pi a samsung tablet, a alcatel tablet and samsung phone. Unfortunatley all of them still ask the first time after a device startup. I am not to sure where i am going wrong.
