android9.0默认打开adb调试以及默认授权RSA秘钥指纹弹框

对于开发的伙伴们避免不了打开调试模式去调试软件看log什么的，为了节省时间默认打开adb调试功能就是一个不错的选择。

1、在系统软件版本是user版本的情况下，就要去修改以下文件：6762_P\build\core\main.mk

ifneq (,$(user_variant))
  # Target is secure in user builds.
  ADDITIONAL_DEFAULT_PROPERTIES += ro.secure=1
  ADDITIONAL_DEFAULT_PROPERTIES += security.perf_harden=1

  ifeq ($(user_variant),user)
    ADDITIONAL_DEFAULT_PROPERTIES += ro.adb.secure=1
    else
    #2019.11.19 by lwz add
	ifeq ($(strip $(MY_MMI_BOOL_DEF_ADB_OPEN)), yes)
	  ADDITIONAL_DEFAULT_PROPERTIES += ro.adb.secure=0
	else
	  ADDITIONAL_DEFAULT_PROPERTIES += ro.adb.secure=1
	endif
  endif

  # Target is less debuggable and adbd is off by default
  #ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=0
    #2019.11.19 by lwz add
    ifeq ($(strip $(MY_MMI_BOOL_DEF_ADB_OPEN)), yes)
	  ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=1
	else
	  ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=0
	endif
endif # !enable_target_debugging

2、默认授权RSA秘钥指纹弹框dialog

frameworks\base\services\usb\java\com\android\server\usb\UsbDebuggingManager.java

        private void listenToSocket() throws IOException {
            try {
                byte[] buffer = new byte[BUFFER_SIZE];
                while (true) {
                    int count = mInputStream.read(buffer);
                    if (count < 0) {
                        break;
                    }

                    if (buffer[0] == 'P' && buffer[1] == 'K') {
                        String key = new String(Arrays.copyOfRange(buffer, 2, count));
                        Slog.d(TAG, "Received public key: " + key);
						//modefi by lwz auto agree to usb connection						
						if(DefineSystemProperties.BOOL_NO_USBDEBUG_DIALOG){
							Message msg = mHandler.obtainMessage(UsbDebuggingHandler.MESSAGE_ADB_ALLOW);
							mFingerprints = getFingerprints(key);
							msg.arg1 = 1;
							msg.obj = key;
							mHandler.sendMessage(msg);
						}else{
							Message msg = mHandler.obtainMessage(UsbDebuggingHandler.MESSAGE_ADB_CONFIRM);
							msg.obj = key;
							mHandler.sendMessage(msg);
						}///end
                    } else {
                        Slog.e(TAG, "Wrong message: "
                                + (new String(Arrays.copyOfRange(buffer, 0, 2))));
                        break;
                    }
                }
            } finally {
                synchronized (this) {
                    closeSocketLocked();
                }
            }
        }
