3.CPU架构

defaultConfig {
   ndk {
       abiFilters 'arm64-v8a','armeabi-v7a','x86','x86_64'

文件依赖

下载的jar放入libs文件夹，so文件放入jniLibs文件夹

android {
    sourceSets {
        main {
            jniLibs.srcDirs = ['src/main/jniLibs']
        }
    }
}

权限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

路径

所有驱动路径

 SerialPortFinder finder = new SerialPortFinder();
 String[] paths = finder.getAllDevicesPath();
 for (String path : paths) {
     Log.i("SerialPortFinder","path:"+path);
 }

通讯

初始化串口

Serial serial = new Serial("/dev/ttyMSM2",30001,SerialMode.RDWR);

设置监听

serial.setOnSerialListener(new OnSerialListener() {

    @Override
    public void onSerialSend(byte[] data) {
        //发送内容
    }

    @Override
    public void onSerialReceived(byte[] data) {
        //接收内容
    }
    
});

打开串口

serial.open();

关闭串口

serial.close();

代理

服务配置

<service
    android:name="android.serial.port.api.SercdService"
    android:directBootAware="true"
    android:enabled="true" />

初始化

Sercd sercd = new Sercd(getContext());

网络接口列表 + 端口

String netInterface = "";
int port = 30001;
Map<String, String> map = sercd.feedNetworkInterfacesList();
for (String key:map.keySet()){
    //wifi是wlan0
    if (key.equals("eth0")){
        netInterface = map.get(key);
    }
}

设置监听

sercd.setOnSercdListener(new OnSercdListener() {
    @Override
    public void onSercdStateChange(ProxyState proxyState) {
        System.out.println("proxyState:"+proxyState);
    }
});

开始代理

sercd.start("/dev/ttyMSM2",netInterface,port);

关闭代理

sercd.stop();

字节工具

Bytecode bytecode = new Bytecode();
byte b = 0b00001111;

Boolean值Byte

byte b = bytecode.toByte(false,false,false,false,true,true,true,true);//00001111

Byte的Boolean[]

boolean[] booleans = bytecode.toBooleans(b);//[false, false, false, false, true, true, true, true]

Byte转十六进制

String hex = bytecode.toHex(b);//0F

Byte转十进制

int dec = bytecode.toDec(b);//15

Byte转八进制

String oct = bytecode.toOct(b);//017

Byte转二进制

String bin = bytecode.toBin(b);//00001111

Byte数组转十六进制字符串

float floatValue = 99.99f;
byte[] data = bytecode.toBytes(floatValue);
String hexString = bytecode.toHex(data);//E1 FA C7 42 

十六进制String转Byte数组

byte[] value = bytecode.toBytes(hexString);//[-31, -6, -57, 66]

Byte数组转Float

float floatValue = 99.99f;
byte[] data = bytecode.toBytes(floatValue);
float value = bytecode.toFloat(new byte[]{data[0],data[1],data[2],data[3]}));//99.99

Byte数组转Short

short shortValue = 33;
byte[] data = bytecode.toBytes(shortValue);
short value = bytecode.toShort(new byte[]{data[0],data[1]}));//33

Byte数组转Int

int intValue = 100;
byte[] data = bytecode.toBytes(intValue);
int value = bytecode.toInt(new byte[]{data[0],data[1],data[2],data[3]}));//100
