Android操作系统可以用于嵌入式系统，同时支持I2C、GPIO、UART等通信协议。以下是使用Java语言实现I2C通信的示例代码：

import java.io.IOException;
import java.util.Arrays;

import com.google.android.things.pio.I2cDevice;
import com.google.android.things.pio.PeripheralManager;
import com.google.android.things.pio.I2cDeviceConnection;

public class I2cHelper {
    private static final String I2C_DEVICE_NAME = "I2C1";
    private static final int I2C_ADDRESS = 0x3C; // I2C从设备地址

    private I2cDevice mI2cDevice;

    public void open() throws IOException {
        PeripheralManager peripheralManager = PeripheralManager.getInstance();
        mI2cDevice = peripheralManager.openI2cDevice(I2C_DEVICE_NAME, I2C_ADDRESS);
    }

    public void close() throws IOException {
        if (mI2cDevice != null) {
            try {
                mI2cDevice.close();
            } finally {
              mI2cDevice = null;
            }
        }
    }

    public byte[] read(int length) throws IOException {
        byte[] buffer = new byte[length];
        int result = mI2cDevice.read(buffer, length);
        if (result != length) {
            throw new IOException("读取失败: " + result + " bytes received instead of " + length);
        }
        return buffer;
    }

    public void write(byte[] buffer, int length) throws IOException {
        mI2cDevice.write(buffer, length);
    }

    public void write(byte[] buffer) throws IOException {
        mI2cDevice.write(buffer, buffer.length);
    }
}

以上代码通过PeripheralManager API提供了一个简单的I2C设备访问接口，它允许在Android Things中实现I2C设备的读写操作。使用该接口时，您还需要修改AndroidManifest.xml文件，将以下权限添加到应用程序标记
