以編程方式接聽 Android 電話

Question

是否可以以編程方式在android中接聽電話？

我發現了一些不可能的地方，但隨后安裝了應用程序https://play.google.com/store/apps/details?id=com.a0softus.autoanswer其工作正常。

我已經搜索了很多並嘗試了很多東西，而且來電拒絕工作正常，但來電接聽不起作用。

我已經嘗試了以下代碼來接聽電話，如下所示：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.res.AssetFileDescriptor;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.KeyEvent;

import java.io.IOException;
import java.lang.reflect.Method;

import app.com.bikemode.MainActivity;
import app.com.bikemode.R;

public class IncomingCallReceiver extends BroadcastReceiver {
    String incomingNumber = "";
    AudioManager audioManager;
    TelephonyManager telephonyManager;
    Context context;
    private MediaPlayer mediaPlayer;

    public void onReceive(Context context, Intent intent) {
        // Get AudioManager
        this.context = context;
        mediaPlayer = new MediaPlayer();
        audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
        // Get TelephonyManager
        telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        if (intent.getAction().equals("android.intent.action.PHONE_STATE")) {
            String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
            if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
                // Get incoming number
                incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);

            }
        }

        if (!incomingNumber.equals("")) {
            // Get an instance of ContentResolver
           /* ContentResolver cr=context.getContentResolver();
            // Fetch the matching number
            Cursor numbers=cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,  new  String[]{ContactsContract.CommonDataKinds.Phone.CONTACT_ID,ContactsContract.CommonDataKinds.Phone.NUMBER},  ContactsContract.CommonDataKinds.Phone.NUMBER +"=?", new String[]{incomingNumber},  null);
            if(numbers.getCount()<=0){ // The incoming number is not  found in the contacts list*/
            // Turn on the mute
            //audioManager.setStreamMute(AudioManager.STREAM_RING,  true);
            // Reject the call
            //rejectCall();
            // Send the rejected message ton app
            //startApp(context,incomingNumber);
            // }

            //audioManager.setStreamMute(AudioManager.STREAM_RING, true);
            //rejectCall();
            //startApp(context, incomingNumber);
            acceptCall();
        }
    }


    private void startApp(Context context, String number) {
        Intent intent = new Intent(context, MainActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.putExtra("number", "Rejected incoming number:" + number);
        context.startActivity(intent);
    }

    private void rejectCall() {
        try {

            // Get the getITelephony() method
            Class<?> classTelephony = Class.forName(telephonyManager.getClass().getName());
            Method method = classTelephony.getDeclaredMethod("getITelephony");
            // Disable access check
            method.setAccessible(true);
            // Invoke getITelephony() to get the ITelephony interface
            Object telephonyInterface = method.invoke(telephonyManager);
            // Get the endCall method from ITelephony
            Class<?> telephonyInterfaceClass = Class.forName(telephonyInterface.getClass().getName());
            Method methodEndCall = telephonyInterfaceClass.getDeclaredMethod("endCall");
            // Invoke endCall()
            methodEndCall.invoke(telephonyInterface);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

    private void acceptCall() {
        try {
           /* // Get the getITelephony() method
            Class<?> classTelephony = Class.forName(telephonyManager.getClass().getName());
            Method method = classTelephony.getDeclaredMethod("getITelephony");
            // Disable access check
            method.setAccessible(true);
            // Invoke getITelephony() to get the ITelephony interface
            Object telephonyInterface = method.invoke(telephonyManager);
            // Get the endCall method from ITelephony
            Class<?> telephonyInterfaceClass = Class.forName(telephonyInterface.getClass().getName());
            Method methodEndCall = telephonyInterfaceClass.getDeclaredMethod("answerRingingCall");
            // Invoke endCall()
            methodEndCall.invoke(telephonyInterface);*/
            Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);
            buttonUp.putExtra(Intent.EXTRA_KEY_EVENT,
                    new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
            context.sendOrderedBroadcast(buttonUp, "android.permission.CALL_PRIVILEGED");
            playAudio(R.raw.a);

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }


    private void playAudio(int resid) {
        AssetFileDescriptor afd = context.getResources().openRawResourceFd(resid);
        try {
            mediaPlayer.reset();
            mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
            mediaPlayer.prepare();
            mediaPlayer.start();
            afd.close();
        } catch (IllegalArgumentException e) {
            Log.w("Rahul Log",e.getMessage());
        } catch (IllegalStateException e) {
            Log.w("Rahul Log", e.getMessage());
        } catch (IOException e) {
            Log.w("Rahul Log", e.getMessage());
        }
    }
}

函數拒絕調用工作正常，但接受調用不起作用。

Answer 1

我的應用程序遇到了同樣的問題。 為接受來電設置一些延遲（~3000 毫秒）。 您還需要在不同的線程中調用acceptCall()方法。

請參閱如何在 Android 5.0 (Lollipop) 中以編程方式接聽來電？

new Thread(new Runnable() {
            @Override
            public void run() {
                acceptCall();
            }
        }).start();

private void acceptCall() {
        try {
            // Get the getITelephony() method
            Class<?> classTelephony = Class.forName(telephonyManager.getClass().getName());
            Method method = classTelephony.getDeclaredMethod("getITelephony");
            // Disable access check
            method.setAccessible(true);
            // Invoke getITelephony() to get the ITelephony interface
            Object telephonyInterface = method.invoke(telephonyManager);
            // Get the endCall method from ITelephony
            Class<?> telephonyInterfaceClass = Class.forName(telephonyInterface.getClass().getName());
            Method methodEndCall = telephonyInterfaceClass.getDeclaredMethod("answerRingingCall");
            // Invoke endCall()
            methodEndCall.invoke(telephonyInterface);

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

Answer 2

這對我有用。

private void answerCall() {
    Log.d(TAG, "Answering call");
    TelephonyManager telephony = (TelephonyManager)
            context.getSystemService(Context.TELEPHONY_SERVICE);
    try {
        Class c = Class.forName(telephony.getClass().getName());
        Method m = c.getDeclaredMethod("getITelephony");
        m.setAccessible(true);
        telephonyService = (ITelephony) m.invoke(telephony);
        //telephonyService.silenceRinger();
        telephonyService.answerRingingCall();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

public void answerCall(){  

   try {
                        // logger.debug("execute input keycode headset hook");
                        Runtime.getRuntime().exec("input keyevent " +
                                Integer.toString(KeyEvent.KEYCODE_HEADSETHOOK));


                    } catch (IOException e) {

                        Log.e("Call Exception ",e.toString());
                        HelperMethods.showToastS(getBaseContext(),"Call Exception one "+e.toString());
                        // Runtime.exec(String) had an I/O problem, try to fall back
                        //    logger.debug("send keycode headset hook intents");
                        String enforcedPerm = "android.permission.CALL_PRIVILEGED";
                        Intent btnDown = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(
                                Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN,
                                        KeyEvent.KEYCODE_HEADSETHOOK));
                        Intent btnUp = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(
                                Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP,
                                        KeyEvent.KEYCODE_HEADSETHOOK));

                         sendOrderedBroadcast(btnDown, enforcedPerm);
                        sendOrderedBroadcast(btnUp, enforcedPerm);
                    }
}

Answer 4

這在 android 版本 9 中對我有用

此代碼在您的答案中單擊...

if (VERSION.SDK_INT >= 26) {
                IncomingActivity incomingActivity = IncomingActivity.this;
                new Thread(new C1736O(incomingActivity)).start();
            } else if (VERSION.SDK_INT >= 21) {
                IncomingActivity incomingActivity2 = IncomingActivity.this;
                new Thread(new C1735LN(incomingActivity2)).start();
            } else {
                Intent intent = new Intent("android.intent.action.MEDIA_BUTTON");
                intent.putExtra("android.intent.extra.KEY_EVENT", new KeyEvent(0, 79));
                IncomingActivity.this.sendOrderedBroadcast(intent, "android.permission.CALL_PRIVILEGED");
                Intent intent2 = new Intent("android.intent.action.MEDIA_BUTTON");
                intent2.putExtra("android.intent.extra.KEY_EVENT", new KeyEvent(1, 79));
                IncomingActivity.this.sendOrderedBroadcast(intent2, "android.permission.CALL_PRIVILEGED");
            }
