本地双录

通过阅读本文,您可以快速了解 IDRS Android SDK 本地双录的相关功能及调用方法。

创建项目工程

打开 Android Studio IDE,用 Android Studio 创建一个项目工程,如下图所示。

说明

Android Studio 下载地址请参见 Android Studio 下载文件归档

引入 SDK

在 build.gradle 中添加依赖。

dependencies {
    implementation ('com.mpaas.android:idrs-process:cp_change_23596.25')//本地双录能力库
    implementation 'com.aliyun.openservices:aliyun-log-android-sdk:2.6.2'//日志库
    implementation 'com.squareup.okhttp3:okhttp:3.11.0'//网络库
    implementation 'com.squareup.okhttp3:logging-interceptor:3.5.0'//网络库
    implementation "com.alibaba:fastjson:1.1.54.android"//json库
}

ProcessSDK 功能

初始化 ProcessSDK

初始化方法仅对 ProcessSDK 初始化所在的 activity 进行前台监听,因此为了精确地计算使用时长,您可以在 Application onCreate 中调用初始化方法。

public class ApplicationDemo extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        //****
        IdrsAppLifecycle.init(this);
        //****
    }
}

在使用流程场景中初始化 ProcessSDK 的方法如下:

ProcessInitConfig config = new ProcessInitConfig();
config.processId = processId;
String appId = intent.getStringExtra("appid"); // appId,在控制台申请的,和包名绑定
String ak = intent.getStringExtra("ak"); // 控制台上的accessKey
String sk = intent.getStringExtra("sk"); // 控制台上的secretKey
config.appId = appId;
config.ak = ak;
config.sk = sk;
config.uid = "test123"; // 账户系统的uid
config.fileDir = getExternalCacheDir().getAbsolutePath(); // 可选,用于指定缓存目录
File file = new File(config.fileDir);
if (!file.exists()) {
    file.mkdirs();
}
ProcessSdk.getInstance().init(RecorderActivity.this, config, new ProcessSdkCallback())

开启摄像头

MPCameraView cameraView = mProcessSdk.startCamera(this, new InitCallback() {
            @Override
            public void initSuccess(int i, int i1) {
                LogUtils.getInstance().debug(TAG, "startCamera success");
            }
});
// 添加到布局中
cameraParent.addView(mMPCameraView, new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

切换摄像头

mProcessSdk.switchCamera();

开始流程

mProcessSdk.startFlow();

开始下一个检测项

mProcessSdk.startNextDetection();

上一章

mProcessSdk.executePrePhases();

重新检测当前项

mProcessSdk.repeatCurrentDetection();

重新播放当前章节

mProcessSdk.retryCurrenPhases();

暂停/恢复播放

mProcessSdk.flowPause();//播放暂停
mProcessSdk.flowResume();//恢复播放

清空默认路径下的视频及 meta/result 文件

mProcessSdk.clearCache();

销毁

请及时使用销毁、否则可能会影响下次初始化。

mProcessSdk.release();

ProcessSDK 回调

// 流程拉取回调,用于更新流程中的配置信息,包括名称、角色等

     Log.i(TAG, "json: " + json);
