android user版本默认开启调试模式

由于项目需要，需要发布版本默认开启调试模式，修改方式如下：

1.开启开发者模式

context.getSharedPreferences(DevelopmentSettings.PREF_FILE,Context.MODE_PRIVATE).edit().putBoolean(

                                    DevelopmentSettings.PREF_SHOW, true).apply();

2.勾选USB调试

   Settings.Global.putInt(context.getContentResolver(),  Settings.Global.ADB_ENABLED, 1);

3.去掉USB插入时的授权提示

　修改frameworks\base\packages\SystemUI\src\com\android\systemui\usb\UsbDebuggingActivity.java的如下内容：

 

        @Override
        public void onReceive(Context content, Intent intent) {
            String action = intent.getAction();
            if (!UsbManager.ACTION_USB_STATE.equals(action)) {
                return;
            }
            /*boolean connected = intent.getBooleanExtra(UsbManager.USB_CONNECTED, false);
            if (!connected) {
                mActivity.finish();
            }*/
	    boolean connected  = false;   //给connect赋值，关掉UI
            if (!connected) {
                mActivity.finish();
            }
            try {
	　　　　IBinder b = ServiceManager.getService(USB_SERVICE);     
	　　　　IUsbManager service = IUsbManager.Stub.asInterface(b);
	　　　　service.allowUsbDebugging(true, mKey);
            } catch (Exception e) {
	　　　　Log.e(TAG, "Unable to notify Usb service", e);
            }
        }
