请按照如下方法进行修改:
frameworks\base\media\java\android\media\MediaFocusControl.java:
1、import packages:
import com.android.internal.telephony.ITelephony;
import android.os.ServiceManager;
 
2、增加获取当前Phone Call State的方法getPhoneCallState():
      private int getPhoneCallState(){
            int phoneCallState = TelephonyManager.CALL_STATE_IDLE;
 
            TelephonyManager telephonyManager = (TelephonyManager)mContext.getSystemService(Context.TELEPHONY_SERVICE);
            ITelephony telephonyService = ITelephony.Stub.asInterface(ServiceManager.getService(Context.TELEPHONY_SERVICE));
 
            if (telephonyService != null) {
                  Log.w(TAG, "getPhoneCallState: mTelephonyService != null");
            try {
                phoneCallState = telephonyService.getPreciseCallState();
                        Log.w(TAG, "getPhoneCallState: telephonyService.getPreciseCallState() = " + phoneCallState);
            } catch (RemoteException ex) {
                  if(telephonyManager != null){
                      phoneCallState = telephonyManager.getCallState();
                              Log.w(TAG, "getPhoneCallState: telephonyManager.getCallState() = " + phoneCallState);
                  }
                Log.w(TAG, "Catch exception when getPreciseCallState: ex = "
                        + ex.getMessage());
            }
        } else {
            Log.w(TAG, "getPhoneCallState: telephonyService == null");
            if(telephonyManager != null){
                phoneCallState = telephonyManager.getCallState();
                        Log.w(TAG, "getPhoneCallState: telephonyManager.getCallState() = " + phoneCallState);
            }
        }
        Log.w(TAG, "getPhoneCallState: phoneCallState = " + phoneCallState);
            return phoneCallState;
      }
 
3、修改
    private boolean canReassignAudioFocus() {
        // focus requests are rejected during a phone call or when the phone is ringing
        // this is equivalent to IN_VOICE_COMM_FOCUS_ID having the focus
        if (!mFocusStack.isEmpty() && mFocusStack.peek().hasSameClient(IN_VOICE_COMM_FOCUS_ID)) {
            return false;
        }
        return true;
    }

    private boolean canReassignAudioFocus() {
        // focus requests are rejected during a phone call or when the phone is ringing
        // this is equivalent to IN_VOICE_COMM_FOCUS_ID having the focus                  
        if (!mFocusStack.isEmpty() && mFocusStack.peek().hasSameClient(IN_VOICE_COMM_FOCUS_ID) && (getPhoneCallState() != TelephonyManager.CALL_STATE_IDLE)) {
                  Log.w(TAG, "canReassignAudioFocus: return false");
            return false;
        }
            Log.w(TAG, "canReassignAudioFocus: return true");
        return true;
    }
