Thank you for your request.
Please provide a Minimal, Reproducible Example using this template in a public GitHub repository so I can debug the issue.

After installing the "@capacitor-community/privacy-screen" package and following the provided steps to enable it in the "capacitor.config.json" and "capacitor.config.ts" files, I built the app and installed it on my iPhone 13 Pro. However, as soon as I put the app into the background by pressing the home button or switching to another app, the app crashed with the "Thread 1: EXC_BAD_ACCESS" exception in the "AppDelegate.swift" file at the line where the class is defined:

class AppDelegate: UIResponder, UIApplicationDelegate {

This issue occurred consistently after enabling the "PrivacyScreen" plugin, and I couldn't find any direct cause for the crash. I checked for any conflicts with other plugins or native code, but the crash seemed to be isolated to the "PrivacyScreen" plugin.

As this exception significantly impacts the stability of the app, I kindly request support from the community to investigate the root cause and find a resolution. I am willing to provide any additional information or logs required for debugging purposes. Any assistance in resolving this critical issue would be highly appreciated. Thank you.

The only thing I did here is to enable the plugin in the app.component.ts

import { Component } from '@angular/core';
import { PrivacyScreen } from '@capacitor-community/privacy-screen';

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.scss'],
})
export class AppComponent {
  constructor() {

  }

  initApp(){
    // ++++++++++++++++++++++++
    // Setup Privacy Screen
    // ++++++++++++++++++++++++
    PrivacyScreen.addListener('screenRecordingStarted', () => {
      // Your code to execute when the screen recording starts
    });
    PrivacyScreen.addListener('screenshotTaken', () => {
      // Your code to execute when the screen recording starts
    });
    PrivacyScreen.enable();
  }
}

We are also experiencing same issue.

We are experiencing the same issue. Steps to reproduce:

• Enable PrivacyScreen on a page
• Put app in iphone background
• After about 15-20 seconds, bring app to foreground
• App restarts and sends crash notification. Xcode shows: EXC_BAD_ACCESS

[RishikeshB]

experiencing the same issue , while enable PrivacyScreen on a page and running the app on background within 8-10 sec the app crashed with the "Thread 1: EXC_BAD_ACCESS" exception in the "AppDelegate.swift"

[godhand1607]

++ also getting this error

UPDATE: It seems to only happen if PrivacyScreen is enabled at startup

I am experiencing the crash and it is disabled in CapacitorConfig. It is only enabled on specific pages.
Example using Ionic Capacitor w/ Angular

capacitor.config.ts:

const config: CapacitorConfig = {
  plugins: {
    PrivacyScreen: {
      enable: false
    }
  }

component.ts file:

ionViewDidEnter() {
   if (Capacitor.isNativePlatform()) {
       PrivacyScreen.enable()
       .then(() => {
           console.log('privacy screen enabled');
       })
       .catch(err => console.error(err));
   }
 }

I tried this way and it was working for a while, but the crashes actually continue. It doesn't seem to solve the problem

[robingenz]

This issue is caused by the disable screenshots feature (see #59).
Version 4.0.0 works.
@dtarnawsky Any idea?

EDIT: Interesting fact: It works without problems if you enable the plugin twice (see #65).

[dtarnawsky]

Not sure why it is functioning this way now but adding 2 secure text fields seems to fix the problem so I've done that in the PR: #69

[robingenz]

Thanks @dtarnawsky! I will publish a new release.
