Android 11 默认打开开发者选项

修改部分

packages/apps/Settings/src/com/android/settings/SettingActivity.java

在 doUpdateTilesList函数里面在获取DevelopmentSettingsEnabler的isDevelopmentSettingsEnabled前，添加以下这一句即可
DevelopmentSettingsEnabler.setDevelopmentSettingsEnabled(this, true);

 DevelopmentSettingsEnabler.setDevelopmentSettingsEnabled(this, true); //加上这一句即可
 final boolean showDev = DevelopmentSettingsEnabler.isDevelopmentSettingsEnabled(this)
           && !Utils.isMonkeyRunning();
   somethingChanged = setTileEnabled(changedList, new ComponentName(packageName,
                   Settings.DevelopmentSettingsDashboardActivity.class.getName()),
           showDev, isAdmin)
           || somethingChanged;

是不是非常简单？
