Question

我正在尝试在我的应用中添加一项内容。我正在尝试的是每当用户接到电话或用户拨打电话时，同时应该开始录制，并且在切断呼叫后必须将录音存储在SD卡中。

问题
1）有时来电记录工作

2）外出不工作

MainActivity.java

public class MainActivity extends AppCompatActivity {

    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);

        PackageManager p = getPackageManager();
        p.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

        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);

Answer 1

从TService删除此if (wasRinging == true)，这是在线布尔检查电话是否在之前的某个时间响铃，即当电话接到电话时，如果拨打电话，它会保持为假，因此，会跳过录音机部分。只是改变它，它应该工作。

只需将此TService代码替换为..

    public class TService extends Service {
    MediaRecorder recorder;
    File audiofile;
    String name, phonenumber;
    String audio_format;
    public String Audio_Type;
    int audioSource;
    Context context;

    Timer timer;
    Boolean offHook = false, ringing = false;
    Toast toast;
    Boolean isOffHook = false;
    private boolean recordstarted = false;

    private static final String ACTION_IN = "android.intent.action.PHONE_STATE";
    private static final String ACTION_OUT = "android.intent.action.NEW_OUTGOING_CALL";
    private CallBr br_call;




    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onDestroy() {
        Log.d("service", "destroy");

        super.onDestroy();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // final String terminate =(String)
        // intent.getExtras().get("terminate");//
        // intent.getStringExtra("terminate");
        // Log.d("TAG", "service started");
        //
        // TelephonyManager telephony = (TelephonyManager)
        // getSystemService(Context.TELEPHONY_SERVICE); // TelephonyManager
        // // object
        // CustomPhoneStateListener customPhoneListener = new
        // CustomPhoneStateListener();
        // telephony.listen(customPhoneListener,
        // PhoneStateListener.LISTEN_CALL_STATE);
        // context = getApplicationContext();

        final IntentFilter filter = new IntentFilter();
        filter.addAction(ACTION_OUT);
        filter.addAction(ACTION_IN);
        this.br_call = new CallBr();
        this.registerReceiver(this.br_call, filter);

        // if(terminate != null) {

我担心社区不喜欢外部链接，所以我在这里发布我的快速演示项目......

<强>的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

        </intent-filter>
    </activity>

    <service android:name=".TService"/>
</application>

<强> MainActivity.java

我正在使用onCreate方法启动TService，请注意，这可能是您项目中的任何活动，或者您可以从中启动服务的任何上下文。

public class MainActivity extends AppCompatActivity {

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

        startService(new Intent(this, TService.class));
    }
}

现在终于，的 TService.java 我已经在Kitkat和Lollipop中进行了测试，并且它正在运行，对于较新的版本，您需要在运行时明确要求Manifest权限，它应该可以正常工作。

public class TService extends Service { MediaRecorder recorder; File audiofile; String name, phonenumber; String audio_format; public String Audio_Type; int audioSource; Context context; Timer timer; Boolean offHook = false, ringing = false; Toast toast; Boolean isOffHook = false; private boolean recordstarted = false; private static final String ACTION_IN = "android.intent.action.PHONE_STATE"; private static final String ACTION_OUT = "android.intent.action.NEW_OUTGOING_CALL"; private CallBr br_call; @Override public IBinder onBind(Intent arg0) { // TODO Auto-generated method stub return null; } @Override public void onDestroy() { Log.d("service", "destroy"); super.onDestroy(); } @Override public int onStartCommand(Intent intent, int flags, int startId) { // final String terminate =(String) // intent.getExtras().get("terminate");// // intent.getStringExtra("terminate"); // Log.d("TAG", "service started"); // // TelephonyManager telephony = (TelephonyManager) // getSystemService(Context.TELEPHONY_SERVICE); // TelephonyManager // // object // CustomPhoneStateListener customPhoneListener = new // CustomPhoneStateListener(); // telephony.listen(customPhoneListener, // PhoneStateListener.LISTEN_CALL_STATE); // context = getApplicationContext(); final IntentFilter filter = new IntentFilter(); filter.addAction(ACTION_OUT); filter.addAction(ACTION_IN); this.br_call = new CallBr(); this.registerReceiver(this.br_call, filter); // if(terminate != null) { // stopSelf(); // } return START_NOT_STICKY; } public class CallBr extends BroadcastReceiver { Bundle bundle; String state; String inCall, outCall; public boolean wasRinging = false; boolean didMakeACall = false; @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 || didMakeACall) { Toast.makeText(context, "ANSWERED", Toast.LENGTH_LONG).show(); String out = new SimpleDateFormat("dd-MM-yyyy hh-mm-ss").format(new Date()); File sampleDir = new File(Environment.getExternalStorageDirectory(), "/MyRecorder"); if (!sampleDir.exists()) { sampleDir.mkdirs(); } String file_name = "Record"; try { audiofile = File.createTempFile(file_name, ".amr", sampleDir); } catch (IOException e) { e.printStackTrace(); } String path = Environment.getExternalStorageDirectory().getAbsolutePath(); System.out.println("PATH"+path); recorder = new MediaRecorder(); // recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL); 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; } } 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) { didMakeACall = true; outCall = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); Toast.makeText(context, "OUT : " + outCall, Toast.LENGTH_LONG).show(); } } } } }
