Amazon FireTV Launch on Start UP

About

Starting from Android 10, apps that need to launch at startup (Auto-launch) need to be granted permission SYSTEM_ALERT_WINDOW (also often called “drawing over other apps”).

Generally, this has not been a problem, since our app detects the missing permission and directs the user to grant the permission.

With the release of generation 2 for Fire TV 4k and 4K max (rounded corners), they run now on FireOS 8 (which is built on Android 11), and the devices require the same permission. The problem is that FireOS 8 does not have the user interface to grant the permission, therefore the only way to get our signage app to launch on startup is to grant the permission via the developer tools command.

Get Started

We recommend installing ADB (Android Debug Bridge) on your computer so you can grant the permission needed for Auto-Launch. This process requires a computer and installing ADB command on it.

Go to Settings > My FireTV > About > Move to the device name (For example. Fire TV Stick 4K max) and press 10 times. You should see the message Developer Mode Enabled.
Go to Settings > My FireTV > Developer Options > and turn on ADB Debugging
Make sure both your Fire TV and your computer are connected to the same Wifi
Note down your FireTV’s IP address, go to Settings -> My Fire TV -> About -> Network, and find the IP Address field.

Mac OS:

Download platform-tools.zip file.
Double-click on the downloaded .zip file to unzip it
Open the folder and in the bottom where the navigation breadcrumb is, right-click and select Open in terminal. If you do not have the breadcrumbs active you can right-click the folder itself> Services > New Terminal at folder
Execute the following command to connect to your Fire TV Stick: ./adb connect <device-ip-here>, for example ./adb connect 192.168.1.115
You should see a screen pop up on the Fire TV asking you to trust the device, and select allow.
To verify that the device is connected, execute command ./adb devices, you should see the device listed.
To grant the permission, execute the following command:./adb shell appops set dk.fadeit.play SYSTEM_ALERT_WINDOW allow
Permission is now granted
