如何在Android中記錄電話？

Question

我想創建一個記錄傳入和傳出呼叫的應用程序，它會在用戶撥打或撥打電話時自動運行。

Answer 1

好的，首先，您需要使用設備策略管理器，並且需要制作設備管理設備。 之后，您必須創建一個BroadCast接收器和一個服務。 我在這里發布代碼並且工作正常。

主要活動：

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類

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

下面的代碼正在為我錄制撥打電話

//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;

//將此方法放在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();
    }
};

//在代碼的下方，使您的設備在揚聲器上

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

//在部分代碼下面開始錄制

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();
    }

//要停止錄音，請記住在通話結束或停止時關閉揚聲器

audioManager.setSpeakerphoneOn(false);

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

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

    }

我想對此發表評論，甚至是它的老帖子。 所以，基本上，我想要結合2個答案，一個來自這篇文章，一個來自我讀過的另一個帖子，不知道它的作者所以請抱歉使用你的方法。

所以，這是我的類，以實現期望的結果：

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

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        PackageManager p = getPackageManager();
        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 {
                mDPM.lockNow();
                finish();
//                 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) {
        if (REQUEST_CODE == requestCode) {
            startService(new Intent(StartActivity.this, TService.class));

在TService類中，您將找到CallReceiever類，它將處理您需要的所有調用。 您可以根據自己的意願添加參數，但重點是重點。

從您的MainActvitiy呼叫服務，將啟動您的接收器。 如果您想直接從收件人錄制媒體，您將收到錯誤，因此，您需要從服務中注冊收件人。 之后，您可以在任何地方呼叫開始錄制和結束錄制。 調用return super.onStartCommand(intent, flags, startId); 這項服務將持續多次通話，請記住這一點。

最后， AndroidManifest.xml文件：

所以，就是它，它與我的三星Galaxy s6 Edge +完美配合，我在Galaxy Note 4和三星J5上進行了測試，非常感謝這篇文章的作者以及關於接收電話的帖子。

Answer 4

pratt的答案有點不完整，因為當你重新啟動設備時，你的應用程序將停止工作，錄制停止，它變得無用。

我在你的項目中添加了一些副本，以完成Pratt的完整工作。

<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>

將此代碼放在DeviceAdminDemo的onReceive中

@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);

}

Answer 5

接受的答案是完美的，除了它不記錄撥出電話。 請注意，對於撥出電話，不可能（盡管我可以通過搜索許多帖子）來檢測電話何時實際應答（如果有人能找到除了搜索通知或日志之外的其他方式，請告訴我）。 最簡單的解決方案是在撥打電話時立即開始錄制，並在檢測到IDLE時停止錄制。 只需添加與上述相同的類，並以這種方式傳出記錄，以確保完整性：

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) {
                                recorder.stop();
                                recordstarted = false;
                            }
                        }
                    }


                }
            }
        }
    }

Answer 6

使用此庫有一個簡單的解決方案。 我在MyService.class中存儲了一個CallRecord類的實例。 首次初始化服務時，將執行以下代碼：

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();
    } 
}

接下來，不要忘記在清單中指定權限。 （我可能在這里有一些額外的東西，但請記住，其中一些僅適用於較新版本的Android）

<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" />

在應用程序的第一次啟動時請求一些權限也是至關重要的。 這里提供了一個指南。
