BroadcastReceiver实现android来去电录音功能（外录）

因为原生android没有提供来去电内录功能，所以只能通过麦克进行通话录音，

<span style="font-size:18px;">/** * 来去电录音，因为去电没有接听的状态，只要拨出就会开始录音 *     * @author jaeuken   * @date 2015-1-4 */public class PhoneBroadcastReceiver extends BroadcastReceiver {private static String outgoingNumber = "";private static String incomeNumber = "";private String state = "";private static MediaRecorder mediaRecorder;  @Overridepublic void onReceive(Context context, Intent intent) {/*去电时：  * 未接：phone_state=OFFHOOK;  * 挂断：phone_state=IDLE  * 来电时:      *   * 未接：phone_state=RINGING  * 已接：phone_state=OFFHOOK;  * 挂断：phone_state=IDLE**/ //如果是拨打电话  if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){ outgoingNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); }if(intent.getAction().equals("android.intent.action.PHONE_STATE")){state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);if("RINGING".equals(state)){incomeNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);}if("OFFHOOK".equals(state)){//来电接通或去电（无法判断是否接通），开始录音Thread recordingThread = new Thread() {@Overridepublic void run() {try {File dirFile = Environment.getExternalStorageDirectory();File file;//根据用来电号码是否为空判断来去电if(incomeNumber!=null&&incomeNumber.length()>0){file = new File(dirFile, "IN_"+incomeNumber +"_" + System.currentTimeMillis() + ".3gp");  }else{file = new File(dirFile, "OUT_"+outgoingNumber +"_" + System.currentTimeMillis() + ".3gp");  }mediaRecorder = new MediaRecorder();  mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);   //获得声音数据源  mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);   // 按3gp格式输出  mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);     mediaRecorder.setOutputFile(file.getAbsolutePath());   //输出文件  mediaRecorder.prepare();mediaRecorder.start();} catch (IllegalStateException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}    //准备  }};recordingThread.start();}if("IDLE".equals(state)){//挂断，停止录音if(mediaRecorder != null){  mediaRecorder.stop();  mediaRecorder.reset();mediaRecorder.release();  mediaRecorder = null;  outgoingNumber = "";incomeNumber = "";}   }}}  }</span>

需要的权限配置

<span style="font-size:14px;"> </span><span style="font-size:18px;"><!-- 在SDCard中创建与删除文件权限 -->      <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>      <!-- 在SDCard写入数据权限 -->      <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>      <!-- 刻入声音权限 -->      <uses-permission android:name="android.permission.RECORD_AUDIO"/>    <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission> </span>

<span style="font-size:18px;"><receiver android:name="com.test.recordphone.PhoneBroadcastReceiver">              <intent-filter >                 <action android:name="android.intent.action.PHONE_STATE"/>               <action android:name="android.intent.action.NEW_OUTGOING_CALL" />            </intent-filter>          </receiver></span>
