Android自动拦截与接听功能APK黑白名单

自动接听与挂断调用关系如下

1. 首先在启动apk初始界面的activity中，启动service服务，开始监听通话状态（InCallService）

   //启动通话状态监听服务
    private void startCallListen() {
        Intent intent = new Intent(CallAndMessageEntranceActivity.this, InCallService.class);
        startService(intent);
}
 

2. 在通话监听服务中，监听通话状态，当通话状态为CALL_STATE_RINGING时处理通话。

public class InCallService extends Service {
    private TelecomManager mTelecomManager;
    private TelephonyManager mTelephonymanager;
    MyPhoneStateListener mMyPhoneStateListener = new MyPhoneStateListener();
 
    @Override
    public void onCreate() {
        Log.e("InCallService", "onCreate()");
        super.onCreate();
 
        //获取电话服务
        mTelecomManager = (TelecomManager) getSystemService(Context.TELECOM_SERVICE);
        mTelephonymanager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
   }
 
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        if (mTelephonymanager == null) {
            mTelephonymanager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        }
        mTelephonymanager.listen(mMyPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
        return super.onStartCommand(intent, flags, startId);
    }
 
    //监听通过话
    public class MyPhoneStateListener extends PhoneStateListener {
 
        @RequiresApi(api = Build.VERSION_CODES.P)
        @Override
        public void onCallStateChanged(int state, final String incomingNumber) {
            super.onCallStateChanged(state, incomingNumber);
            switch (state) {
                case TelephonyManager.CALL_STATE_IDLE:
                    //通话空闲状态
                    break;
                case TelephonyManager.CALL_STATE_RINGING:
                    //通话来电状态
                    try {
                        Log.e("C_M_BlackCallService", "Monitor incoming calls");
                        //拦截来电判断来电时黑名单or白名单
                        splitWhiteAndBlack(incomingNumber);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                    break;
                case TelephonyManager.CALL_STATE_OFFHOOK:
                    //电话挂起状态
                    break;
            }
 
        }
    }
    //incomingNumber:来电号码 依据来电号码判断黑白名单
    private void splitWhiteAndBlack(String incomingNumber) {
        //1.黑名单自动挂断
        mTelecomManager.endCall();
        //2.白名单自动接听
        mTelecomManager.acceptRingingCall();
    }
    @Override
    public void onDestroy() {
        super.onDestroy();
 
}
