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();

To install the NHG47K build (Android 7.1.2) on your RK322x TV box, you must first verify your hardware board version to ensure compatibility and then use a PC-based flashing tool. 1. Identifying the Correct Firmware
The "NHG47K" build is a common Android 7.1.2 image used for RK322x and RK3229 devices. However, flashing the wrong version for your specific Wi-Fi chip or board revision can result in no Wi-Fi or a "bricked" device.
Check the Board: Open your TV box (usually 4 screws at the bottom) and look for the board revision number (e.g., MXQ-4K-R329Q-V3.1 or XT-MX4VB-V02).
Download Source: You can often find these images on community forums like 4PDA or specialized firmware repositories like AndroidPCtv. 2. Preparation Checklist
Hardware: A USB Type-A to USB Type-A cable (male-to-male) and a toothpick or paperclip.
Drivers: Download and install the Rockchip Driver Assistant to ensure your PC recognizes the box.
Flashing Tool: Use RKBatchTool or RKDevTool (formerly AndroidTool). 3. Flashing Process
Load Firmware: Open RKBatchTool.exe, click the "..." button, and select your downloaded .img firmware file. Enter MaskROM/Loader Mode: Unplug the power from the TV box. Yes – but with caveats
Insert a toothpick into the AV port to hold down the hidden reset button.
While holding the button, connect the box to your PC via the USB cable (usually the USB-4 port works best).
Verify Connection: If successful, a square in the tool will turn green (or blue depending on the mode).
Execute Flash: Click Restore (recommended for a clean install) or Upgrade.
Finish: Wait for the "Success" message. The box will reboot automatically; the first boot may take 5–10 minutes. Important Considerations RK322X Box Firmware 7.1.2 Details | PDF - Scribd
