Once your box boots into Android 7.1.2 NHG47K:
You need:
Open your TV box and check the model number on the PCB (e.g., RK3229_D4_V2.0, MX4N, R29). Firmware is board-specific.
A common feature developed for these boxes is a "Kiosk Mode" (locking the device to a single app). Here is the implementation strategy:
Step A: Create a "Launcher" App
You need to develop an Android App that declares itself as a Launcher in the AndroidManifest.xml.
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
Step B: Handle Legacy Permissions (Android 7.1) Android 7.1 does not have the modern runtime permission model of Android 10+. However, to write settings or overlay other apps, you must request specific permissions.
Step C: Root Access (Usually Required for System Apps)
Most RK322x boxes come with su binary pre-installed (Rooted). To develop a feature that controls hardware (like rebooting the device programmatically), you need to execute shell commands via Java.
Java Code Example (Reboot Feature):
public void rebootDevice()
try
Process proc = Runtime.getRuntime().exec(new String[] "su", "-c", "reboot" );
proc.waitFor();
catch (Exception ex)
ex.printStackTrace();
You will need the RKDevTool (Rockchip Create Upgrade Disk Tool) and a USB Male-to-Male cable or an SD Card.
