1. 流程示意图：
2. 添加appid信息
在自身应用AndroidManifest.xml中添加开发者联盟创建应用时生成的appid信息，name为"com.huawei.hms.client.appid"，value为"appid="，用自己注册的appid。
AndroidManifest.xml
android:name="com.huawei.hms.client.appid" android:value="appid=******" /> 3. 创建LocalSocket客户端并注册 应用启动，创建LocalSocket客户端，建议与系统LocalSocket服务器的通信通道，然后向系统注册。 创建LocalSocket客户端 ApiTest.java public Boolean openLocalSocket() { try { Log.d(TAG, "Enter OpenSocket"); // 1.create socket, socketName is resmon clientSocket = new LocalSocket(); clientSocketAddr = new LocalSocketAddress(NAME_SOCKET, LocalSocketAddress.Namespace.ABSTRACT); // 2.connect server clientSocket.connect(clientSocketAddr); Log.i(TAG, "openLocalSocket success"); // 3.new Thread to receive msg from server final BufferedReader readStream = new BufferedReader(new InputStreamReader(clientSocket.getInputStream())); new Thread(new Runnable() { @Override public void run() { try { String respMsg; int readed = 0; while (readed != -1) { char[] revMsg = new char[BUFFER_SIZE]; char[] msgType = new char[2]; // 4.received msg from server, include msg head and body, head len is 42 Bytes readed = readStream.read(revMsg, 0, BUFFER_SIZE); /** * 5. get msgType(MSGTYPE_BEGIN_INDEX = 6, * MSGTYPE_END_INDEX = 7), * revMsg[MSGTYPE_BEGIN_INDEX] == 1 is reqMsg, * revMsg[MSGTYPE_BEGIN_INDEX] == 2 is respMsg */ msgType[0] = revMsg[MSGTYPE_BEGIN_INDEX]; msgType[1] = revMsg[MSGTYPE_END_INDEX]; int bodyBegin = RESP_HEAD_LEN; if (msgType[0] == 1) { bodyBegin = REQ_HEAD_LEN; } /** * 6. get body msg. bodyBegin is REQ_HEAD_LEN=44 or RESP_HEAD_LEN=46 * and translate to json string */ respMsg = String.valueOf(revMsg, bodyBegin, revMsg.length - bodyBegin); respMsg = respMsg.trim(); MainActivity.MyHandler handler = MainActivity.getMyHandler(); Message msg = new Message(); msg.what = MSG_RECEIVE; msg.obj = respMsg; handler.sendMessage(msg); Log.d(TAG, "---------> revMsg is : " + respMsg); } } catch (IOException e) { Log.d(TAG, e.getMessage()); } } }).start(); } catch (IOException e) { Log.d(TAG, e.getMessage()); return false; } return true; } 注册部分： ApiTest.java public Boolean registerApp() { try { if (clientSocket == null) { Log.w(TAG, "please open socket first!!!"); return false; } MsgHeader msgHeader = new MsgHeader(); // 1.generate msg head,hdrData is byte[] byte[] hdrData = msgHeader.getNewHeaderMsg(registerMessage.length()); // 2.generate msg head and body, body is as this: byte[] msgByte = registerMessage.getBytes(); byte[] newByte = concatByte(hdrData, msgByte); writeSocket(newByte); Log.d(TAG, "send msg: " + registerMessage); } catch (IOException e) { Log.d(TAG, e.getMessage()); return false; } return true; } 4. 查询系统可用网络接口等信息 代码如下： ApiTest.java public Boolean getAvailableNetInterface() { try { if (clientSocket == null) { Log.e(TAG, "please open socket first"); return false; } MsgHeader msgHeader = new MsgHeader(); byte[] hdrData = msgHeader.getNewHeaderMsg(getAvailableNetInterfaceMessage.length()); Log.d(TAG, "hdrData = " + Arrays.toString(hdrData)); byte[] msgByte = getAvailableNetInterfaceMessage.getBytes(); byte[] newByte = concatByte(hdrData, msgByte); Log.d(TAG, "newByte = " + Arrays.toString(newByte)); writeSocket(newByte); Log.d(TAG, "send msg: " + getAvailableNetInterfaceMessage); } catch (IOException e) { Log.d(TAG, e.getMessage()); return false; } return true; } 5. 应用结束，解除注册。 代码如下： ApiTest.java public Boolean unRegisterApp() { try { if (clientSocket == null) { Log.w(TAG, "please open socket first"); return false; } MsgHeader msgHeader = new MsgHeader(); byte[] hdrData = msgHeader.getNewHeaderMsg(unRegisterMessage.length()); Log.d(TAG, "unRegisterApp hdrData = " + Arrays.toString(hdrData)); byte[] msgByte = unRegisterMessage.getBytes(); byte[] newByte = concatByte(hdrData, msgByte); writeSocket(newByte); Log.d(TAG, "send msg: " + unRegisterMessage); } catch (IOException e) { Log.d(TAG, e.getMessage()); return false; } return true; }
