在公司的日常工作中，最多的就是修改客户订制的Launcher，开机动画，开机logo，设备型号的修改。。。

    通常修改的路径在device/amlogic/p212/p212.mk，查看p212.mk如下

只需修改PRODUCT_MODEL := xxx

编译整包，烧录到盒子上就可以看到如下

这里，显示device name和model是相同的，如果有客户想更改Device name 为x01

则需要到TvSetting里去修改了

cd 进入packages/apps/TvSettings 键入搜索命令grep “device name” * -Rn找到如下：

Settings/src/com/android/tv/settings/name/DeviceManager.java:28:     * @return The device name.
Settings/src/com/android/tv/settings/name/DeviceManager.java:35:     * Sets the system device name.
Settings/src/com/android/tv/settings/name/DeviceManager.java:41:     * @param name The new device name.
Settings/src/com/android/tv/settings/name/DeviceNameSettingsActivity.java:143:        if (DEBUG) Log.v(TAG, String.format(“Setting device name to %s”, name));
Settings/src/com/android/tv/settings/util/bluetooth/BluetoothScanner.java:382:                // Older Bluetooth stacks may append a null character to a device name
Settings/src/com/android/tv/settings/util/bluetooth/BluetoothNameUtils.java:41:     * Decode the setup type integer from the Bluetooth device name.
Settings/src/com/android/tv/settings/about/AboutActivity.java:94:     * Intent action of device name activity.

vi查询Settings/src/com/android/tv/settings/name/DeviceNameSettingsActivity.java +143找到如下代码

private void setDeviceName(String name) {
        if (DEBUG) Log.v(TAG, String.format(“Setting device name to %s”, name));
        DeviceManager.setDeviceName(getApplicationContext(), name);
    }

继续跟代码 grep “DeviceManager” * -Rn：

Settings/src/com/android/tv/settings/name/DeviceNameSummaryFragment.java:97:        String deviceName = DeviceManager.getDeviceName(getActivity());
Settings/src/com/android/tv/settings/name/DeviceManager.java:23:public class DeviceManager {
Settings/src/com/android/tv/settings/name/DeviceNameSettingsActivity.java:144:        DeviceManager.setDeviceName(getApplicationContext(), name);
Settings/src/com/android/tv/settings/about/AboutActivity.java:48:import com.android.tv.settings.name.DeviceManager;
Settings/src/com/android/tv/settings/about/AboutActivity.java:217:                    .description(DeviceManager.getDeviceName(AboutActivity.this))

查询vi Settings/src/com/android/tv/settings/name/DeviceManager.java +23 如下：

红色标注的部分，这里返回值改成 return “X01”;

然后编译Settings验证即可。
