Android端接入SDK代碼

注意

<service android:name="com.tencent.cloud.qcloudasrsdk.onesentence.recorder.QCloudAudioMp3RecoderService" />

需要放在application標簽內(nèi)
初始化接口

private static QCloudOneSentenceRecognizer recognizer;
    // Setup activity layout
    @Override protected void onCreate(Bundle savedInstanceState)
    {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);

        String cmdLine = updateUnityCommandLineArguments(getIntent().getStringExtra("unity"));
        getIntent().putExtra("unity", cmdLine);

        mUnityPlayer = new UnityPlayer(this, this);
        setContentView(mUnityPlayer);
        mUnityPlayer.requestFocus();

        recognizer = new QCloudOneSentenceRecognizer(this, apppId, secretId, secretKey);
        recognizer.setCallback(this);

    }

開始錄音

    public static void OnBtnOpen(){
        System.out.println("開始錄音");
        try {
            /**
             * setDefaultParams 默認參數(shù)param

             */
            recognizer.setDefaultParams(0, 0, 1, 1,null,null);
            recognizer.getDefaultParams().setReinforceHotword(1); // 開啟熱詞增強
            recognizer.recognizeWithRecorder();
            recognizer.setQCloudOneSentenceRecognizerAudioPathListener(new QCloudOneSentenceRecognizerAudioPathListener() {
                @Override

                    System.out.println("callBackAudioPath: audioPath="+audioPath);
                }
            });
        } catch (Exception e) {

            System.out.println("exception msg" + e.getMessage());
        } finally {
        }
    }

結(jié)束錄音

    public static void OnBtnStop(){
        System.out.println("結(jié)束錄音");
        recognizer.stopRecognizeWithRecorder();
    }
