录音-如何在android中记录电话?

我想制作一个记录来电和去电的应用程序,并在用户接到或打出任何电话时自动运行。

好的,首先,您需要使用设备策略管理器,并需要将设备设置为管理设备。 之后,您必须创建一个BroadCast接收器和一个服务。 我在这里发布代码,并且可以正常工作。

主要活动:

public class MainActivity extends Activity {
    private static final int REQUEST_CODE = 0;
    private DevicePolicyManager mDPM;
    private ComponentName mAdminName;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        try {
            // Initiate DevicePolicyManager.
            mDPM = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
            mAdminName = new ComponentName(this, DeviceAdminDemo.class);

            if (!mDPM.isAdminActive(mAdminName)) {
                Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
                intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName);
                intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION, "Click on Activate button to secure your application.");
                startActivityForResult(intent, REQUEST_CODE);
            } else {
                // mDPM.lockNow();
                // Intent intent = new Intent(MainActivity.this,
                // TrackDeviceService.class);
                // startService(intent);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } 
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (REQUEST_CODE == requestCode) {
                Intent intent = new Intent(MainActivity.this, TService.class);
                startService(intent);
        }
    }

}

// DeviceAdminDemo类

public class DeviceAdminDemo extends DeviceAdminReceiver {
    @Override

以下代码对我有用,可以记录去电

//Call Recording varibales
private static final String AUDIO_RECORDER_FILE_EXT_3GP = ".3gp";
private static final String AUDIO_RECORDER_FILE_EXT_MP4 = ".mp4";
private static final String AUDIO_RECORDER_FOLDER = "AudioRecorder";

private MediaRecorder recorder = null;
private int currentFormat = 0;
private int output_formats[] = { MediaRecorder.OutputFormat.MPEG_4,
        MediaRecorder.OutputFormat.THREE_GPP };
private String file_exts[] = { AUDIO_RECORDER_FILE_EXT_MP4,
        AUDIO_RECORDER_FILE_EXT_3GP };

AudioManager audioManager;

//将此方法放在oncreate()方法之外

private String getFilename() {
    String filepath = Environment.getExternalStorageDirectory().getPath();
    File file = new File(filepath, AUDIO_RECORDER_FOLDER);

    if (!file.exists()) {
        file.mkdirs();
    }

    return (file.getAbsolutePath() + "/" + System.currentTimeMillis() + file_exts[currentFormat]);
}

private MediaRecorder.OnErrorListener errorListener = new MediaRecorder.OnErrorListener() {
    @Override
    public void onError(MediaRecorder mr, int what, int extra) {
        Toast.makeText(CallActivity.this,
                "Error: " + what + ", " + extra, Toast.LENGTH_SHORT).show();
    }
};

private MediaRecorder.OnInfoListener infoListener = new MediaRecorder.OnInfoListener() {
    @Override
    public void onInfo(MediaRecorder mr, int what, int extra) {
        Toast.makeText(CallActivity.this,
                "Warning: " + what + ", " + extra, Toast.LENGTH_SHORT)
                .show();
    }
};

//在代码下面,使您的设备在扬声器上

    audioManager = (AudioManager)getApplicationContext().getSystemService(Context.AUDIO_SERVICE); 
    audioManager.setMode(AudioManager.MODE_IN_CALL);
    audioManager.setSpeakerphoneOn(true);

//在代码下面开始录制

recorder = new MediaRecorder();
    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    recorder.setOutputFormat(output_formats[currentFormat]);
    //recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
    recorder.setOutputFile(getFilename());
    recorder.setOnErrorListener(errorListener);
    recorder.setOnInfoListener(infoListener);

    try {
        recorder.prepare();
        recorder.start();
    } catch (IllegalStateException e) {
         Log.e("REDORDING :: ",e.getMessage());
            e.printStackTrace();
    } catch (IOException e) {
        Log.e("REDORDING :: ",e.getMessage());
        e.printStackTrace();
    }

//要停止录音,请记住在通话结束或停止时关闭扬声器

audioManager.setSpeakerphoneOn(false);

    try{
        if (null != recorder) {
            recorder.stop();
            recorder.reset();
            recorder.release();

            recorder = null;
        }
    }catch(RuntimeException stopException){

    }

并授予清单文件的权限,

<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

我想对此发表评论,甚至强硬其旧帖子。 所以,基本上,我想结合两个答案,一个来自本帖子,另一个来自我读过的另一帖子,不知道它的作者,因此,抱歉使用您的方法。

因此,这是我的类,可以实现所需的结果:

    public class StartActivity extends Activity {
    public static final int REQUEST_CODE = 5912;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        ComponentName componentName = new ComponentName(this, StartActivity.class); // activity which is first time open in manifiest file which is declare as <category android:name="android.intent.category.LAUNCHER" />
        p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
        startService(new Intent(this, StartService.class));
        startService(new Intent(this, SmsOutgoingService.class));
        try {
            // Initiate DevicePolicyManager.
            DevicePolicyManager mDPM = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
            ComponentName mAdminName = new ComponentName(this, DeviceAdminReciever.class);

            if (!mDPM.isAdminActive(mAdminName)) {
                Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
                intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName);
                intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION, "Click on Activate button to secure your application.");
                startActivityForResult(intent, REQUEST_CODE);
            } else {

AndroidManifest.xml类中,您将找到CallReceiever类,该类将处理呼叫中所需的一切。 您可以根据需要添加参数,但是要点很重要。

从MainActvitiy致电服务,该服务将启动您的接收方。 如果要直接从接收方录制媒体,则会出错,因此,需要从服务中注册接收方。 之后,您可以随时随地调用开始录制和结束录制。呼叫AndroidManifest.xml将使该服务持续多个呼叫,因此请记住这一点。

最后AndroidManifest.xml文件:

可接受的答案是完美的,除了它不记录去电。 请注意,对于拨出电话,不可能(就像我从搜寻许多帖子中所知道的那样)来检测呼叫的实际应答时间(如果有人可以找到搜寻通知或日志以外的其他方式,请让我知道)。 最简单的解决方案是在拨出电话时立即开始录音,而在检测到IDLE时停止录音。 只需以上述方式添加与上述相同的类并进行传出记录,以确保完整性:

private void startRecord(String seed) {
        String out = new SimpleDateFormat("dd-MM-yyyy hh-mm-ss").format(new Date());
        File sampleDir = new File(Environment.getExternalStorageDirectory(), "/TestRecordingDasa1");
        if (!sampleDir.exists()) {
            sampleDir.mkdirs();
        }
        String file_name = "Record" + seed;
        try {
            audiofile = File.createTempFile(file_name, ".amr", sampleDir);
        } catch (IOException e) {
            e.printStackTrace();
        }
        String path = Environment.getExternalStorageDirectory().getAbsolutePath();

        recorder = new MediaRecorder();

        recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION);
        recorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);
        recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
        recorder.setOutputFile(audiofile.getAbsolutePath());
        try {
            recorder.prepare();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        recorder.start();
        recordstarted = true;
    }


    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(ACTION_IN)) {
            if ((bundle = intent.getExtras()) != null) {
                state = bundle.getString(TelephonyManager.EXTRA_STATE);
                if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
                    inCall = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
                    wasRinging = true;
                    Toast.makeText(context, "IN : " + inCall, Toast.LENGTH_LONG).show();
                } else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
                    if (wasRinging == true) {

                        Toast.makeText(context, "ANSWERED", Toast.LENGTH_LONG).show();

                        startRecord("incoming");
                    }
                } else if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
                    wasRinging = false;
                    Toast.makeText(context, "REJECT || DISCO", Toast.LENGTH_LONG).show();
                    if (recordstarted) {
                        recorder.stop();
                        recordstarted = false;
                    }
                }
            }
        } else if (intent.getAction().equals(ACTION_OUT)) {
            if ((bundle = intent.getExtras()) != null) {
                outCall = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
                Toast.makeText(context, "OUT : " + outCall, Toast.LENGTH_LONG).show();
                startRecord("outgoing");
                if ((bundle = intent.getExtras()) != null) {
                    state = bundle.getString(TelephonyManager.EXTRA_STATE);
                    if (state != null) {
                        if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
                            wasRinging = false;
                            Toast.makeText(context, "REJECT || DISCO", Toast.LENGTH_LONG).show();
                            if (recordstarted) {

                        }
                    }


                }
            }
        }
    }

pratt的答案有点不完整,因为当您重新启动设备时,您的应用程序将停止工作,停止录制,这将变得毫无用处。

我要添加一些行复制到您的项目中以完成Pratt答案的工作。

<receiver
        android:name=".DeviceAdminDemo"
        android:permission="android.permission.BIND_DEVICE_ADMIN">
        <meta-data
            android:name="android.app.admin"
            android:resource="@xml/device_admin" />

        <intent-filter>
            <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
            <action android:name="android.app.action.DEVICE_ADMIN_DISABLED" />
            <action android:name="android.app.action.DEVICE_ADMIN_DISABLE_REQUESTED" />
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <category android:name="android.intent.category.HOME" />
        </intent-filter>
    </receiver>

将此代码放在DeviceAdminDemo的onReceive上

@Override
public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);

    context.stopService(new Intent(context, TService.class));
    Intent myIntent = new Intent(context, TService.class);
    context.startService(myIntent);

}

使用此库可以解决此问题。 我将CallRecord类的实例存储在MyService.class中。 首次初始化服务时,将执行以下代码:

public class MyService extends Service {

    public static CallRecord callRecord;

    @Override
    public void onCreate() {
        super.onCreate();

        callRecord = new CallRecord.Builder(this)
                .setRecordFileName("test")
                .setRecordDirName("Download")
                .setRecordDirPath(Environment.getExternalStorageDirectory().getPath()) // optional & default value
                .setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB) // optional & default value
                .setOutputFormat(MediaRecorder.OutputFormat.AMR_NB) // optional & default value
                .setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION) // optional & default value
                .setShowSeed(false) // optional, default=true ->Ex: RecordFileName_incoming.amr || RecordFileName_outgoing.amr
                .build();
        callRecord.enableSaveFile();
        callRecord.startCallReceiver();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        callRecord.stopCallReceiver();
    } 
}

接下来,不要忘记在清单中指定权限。 (我可能在这里有一些其他功能,但请记住,其中一些仅对于较新版本的Android才是必需的)

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.PROCESS_INCOMING_CALLS" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

在应用程序的第一次启动时请求一些权限也很重要。 这里提供了指南。

如果我的代码不起作用,可以在这里找到替代代码。 希望对您有帮助。
