HarmonyOS 鸿蒙Next中开启混淆后，截图会弹出隐私泄露的警告弹窗，点确认后会关闭app。

【问题分析】

楼主检查一下是否是因为再EntryAbility设置主窗口为隐私窗口，实现全局防截屏，在debug环境没有生效在release生效了

【参考代码】

import { ConfigurationConstant, UIAbility } from '@kit.AbilityKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { window } from '@kit.ArkUI';
import { BusinessError } from '@kit.BasicServicesKit';

const DOMAIN = 0x0000;

export default class EntryAbility extends UIAbility {
  onCreate(): void {
    try {
      this.context.getApplicationContext().setColorMode(ConfigurationConstant.ColorMode.COLOR_MODE_NOT_SET);
    } catch (err) {
      hilog.error(DOMAIN, 'testTag', 'Failed to set colorMode. Cause: %{public}s', JSON.stringify(err));
    }
    hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onCreate');
  }

  onDestroy(): void {
    hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onDestroy');
  }

  onWindowStageCreate(windowStage: window.WindowStage): void {
    // Main window is created,set main page for this ability
    hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onWindowStageCreate');
    // Get the main window
    windowStage.getMainWindow((err: BusinessError, data) => {
      let errCode: number = err.code;
      if (errCode) {
        console.error('Failed to obtain the main window. Cause: ' + JSON.stringify(err));
        return;
      }
      let windowClass: window.Window = data;
      console.info('Succeeded in obtaining the main window. Data: ' + JSON.stringify(data));
      // Set the window privacy mode
      let isPrivacyMode: boolean = true;
      try {
        windowClass.setWindowPrivacyMode(isPrivacyMode, (err: BusinessError) => {
          const errCode: number = err.code;
          if (errCode) {
            console.error('Failed to set the window to privacy mode. Cause:' + JSON.stringify(err));
            return;
          }
          console.info('Succeeded in setting the window to privacy mode.');
        });
      } catch (exception) {
        console.error('Failed to set the window to privacy mode. Cause:' + JSON.stringify(exception));
      }
    });

    windowStage.loadContent('pages/Index', (err) => {
      if (err.code) {
        hilog.error(DOMAIN, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err));
        return;
      }
      hilog.info(DOMAIN, 'testTag', 'Succeeded in loading the content.');
    });
  }

  onWindowStageDestroy(): void {
    // Main window is destroyed, release UI related resources
    hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onWindowStageDestroy');
  }

  onForeground(): void {
    // Ability has brought to foreground
    hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onForeground');
  }

  onBackground(): void {
    // Ability has back to background
    hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onBackground');
  }
};
