Android call answers programmatically

Question

Can I answer a call programmatically in Android?

I found in some places that this is not possible, but then installed the application https://play.google.com/store/apps/details?id=com.a0softus.autoanswer works fine.

I searched and tried a lot of things a lot, in addition, the rejection of the call works fine, but the answer to the call does not work.

I tried the following code to answer calls, as shown below:

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()); } } } 

The call reject function works fine, but the call reception does not work.

Answer 1

I ran into the same problem for my application. Set a delay to receive an incoming call (~ 3000 ms). You also need to call the acceptCall() method on another thread.

 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

This works for me.

 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(); } } 

Answer 3

 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

this is work for me in Android version 9

this code in your response to a click ...

 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"); }
