1.1 Get the SDK and demo

Download the SDK and demo

Note

By downloading and using the SDK, you agree to the Alibaba Cloud Workspace SDK Privacy Policy.

Do not distribute them to any third party without Alibaba Cloud's consent.

Integration requirements

Minimum supported iOS version: 10.0

Due to iOS API availability, peripheral mouse and keyboard features require iOS 13.4 or later.

SDK integration

Unzip the SDK and copy it into your project.
Link the SDK library.

Go to Target --> Build Phases --> Link Binary With Libraries --> + --> Add Other --> Add Files and select the required framework.
Set the embed option.

Go to Target --> General --> Frameworks, Libraries, and Embedded Content, find ASPEngineSDK.framework, and select Embed Without Signing.

SDK permissions

Add the required permissions for ASPEngineSDK to your project's Info.plist file.

1. Microphone permission

Privacy - Microphone Usage Description

2. Camera permission

Privacy - Camera Usage Description

SDK signing

The SDK is a dynamic library and must be signed for on-device debugging or for App Store submission.

Get a signing ID

To find your signing ID, run:

security find-identity -v -p codesigning

If you don't have a local certificate, log in to your Apple Developer account and download the provisioning profile. Right-click the downloaded file, choose Get Info, and find the SHA-1 field of the target certificate. This value is the signing ID.

Signing & Capabilities

In your project target, correctly configure the certificate in the Signing & Capabilities tab.

Add a signing shell script. This script is required for physical devices but not for simulators.

Go to Target --> Build Phases --> + --> New Run Script Phase and paste the shell script content. See the sample signing shell script below.

Note: This Run Script phase must be placed after the Embed Frameworks phase.

Sample signing shell script

set -e
SHELL_PATH="${PROJECT_DIR}/ASPDemo/Lib/ASPEngineSDK/ASPEngineSDK.framework/link_and_sign.sh"
KEY_ID="Your certificate's signing ID"
echo "===> Signing using $KEY_ID"
/bin/bash -c "${SHELL_PATH}"\ "${TARGET_BUILD_DIR}"\ "${FRAMEWORKS_FOLDER_PATH}"\ "${KEY_ID}"

Project configuration

Disable Bitcode.

Go to Target --> Build Settings --> Build Options --> Enable Bitcode and set the option to No.

The message channel uses the DataChannel named wy_vdagent_default_dc.

The message size is limited to 500 KB.

The basic message format is as follows:

DataChannel: Messages from client to guest

Action: insertcontact, insertsms, or sendcontactvcf

insertcontact: Inserts a contact.

The required name parameter specifies the contact name.

The required phonenumber parameter specifies the phone number.

insertsms: Inserts an SMS.

The required phonenumber parameter specifies the phone number.

The required textbody parameter specifies the SMS content.

The optional canInsertdb parameter specifies whether to insert the message into the cloud phone's SMS database. The default is 0 (do not insert); set to 1 to insert.

Example: let jsonarray = [{'action': 'insertcontact','importdata':[{ 'name': '**', 'phonenumber': '**' }, { 'name': '**', 'phonenumber': '**' }]},{'action': 'insertsms','importdata':[{'phonenumber':'**','textbody':'**,"canInsertdb":0/1}]}]

sendcontactvcf: Inserts contacts from a vcf file.

The required data parameter contains the vcf file data stream. Large files must be chunked, with a maximum chunk size of 1 MB.

The required allsize parameter is the total size of the vcf data.

Note

The timestamp parameter is required. Use the same timestamp for all chunks of a single vcf file to ensure correct reassembly.

Example: {'action': 'sendcontactvcf', 'importdata': {'data': '', 'allsize': total_file_size, 'timestamp': current_timestamp}}.

public void processByteArrayInChunks(byte[] data) {
    int chunkSize = 512 * 1024; // 512 KB
    int length = data.length;
    long timestamp = System.currentTimeMillis();
    for (int i = 0; i < length; i += chunkSize) {
        int end = Math.min(i + chunkSize, length);
        byte[] chunk = Arrays.copyOfRange(data, i, end);
        String str = new String(chunk, StandardCharsets.UTF_8);
        /**
          {'action': 'sendcontactvcf','importdata':{"data":str, "allsize":length, "timestamp":timestamp}}
        */
    }
}

String recvData = "";
int recvSize = 0;
long recvTimestamp = 0;
public void onMessageReceive(byte[] message) {
  String action = getAction(message);
  String data = getData(message);
  int length = data.length;
  int allSize = getAllSize(message);
  long timestamp = getTimestamp(message);
  if (timestamp != recvTimestamp) {
    clearRecv();
  }
  if (action.equals("sendcontactvcf")) {
    recvSize += length;
    recvData = recvData + data;
    if (recvSize >= allSize) {
      // Write recvData to a vcf file and insert contacts.
      insertContact(vcfFilePath);
      sendack();
      clearRecv();
    }
  }
}

public void clearRecv() {
  recvData = "";
  recvSize = 0;
  recvTimestamp = 0;
}

DataChannel: Messages from guest to client

Action: openeditsms, openphone, or rotation

openeditsms: Opens the SMS editor page.

The optional importdata.phonenumber parameter specifies the phone number.

The optional textbody parameter specifies the SMS content.

Example: {'action': 'openeditsms',importdata:{"phonenumber":"***", "textbody":"***"}}

openphone: Opens the phone dialer page.

The optional importdata.phonenumber parameter specifies the number to call. If provided, the dialer opens with this number; otherwise, the main dialer page opens.

Example: {'action': 'openphone','importdata':{"phonenumber":"***"}} or {'action': 'openphone'}

DataChannel ACK message

Action: ack

ack: Reports the processing status of a received message. Either the client or guest can send an ack response if required by the application's logic.

The required source parameter is the action from the original message.

The required code parameter is the status code, with the following valid values: 0 (Unknown), 1 (Executing), 2 (Success), 3 (Failure), and 4 (Not Supported).

Example: {'action': 'ack','importdata':{"source":"***", "code": *,"id":*}}
