Hello, I just created an application where the user is not allowed to take screenshot and it runs well, but when i go to cropping image page use (cordova-plugin-crop) it didn't work.

Cordova CLI version and cordova platform version

cordova --version                                    11.0.0
cordova platform version android                     9.1.0

Thanks in advance.

====== EDIT ======

I think this issue is not related with this plugin, I suggest the solution is from cordova-plugin-crop not in this plugin. I will close this issue

great plugin. in testing i did run into an issue. i used the apache "inAppBrowser" and just used google.com as the url. I then simply hit the home button. in the console i get the message "Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates." testing the rest of the app in all the other functions it worked great. I am using cordova 3.6.3 on a iPad Air 2 running ios 8.1. Not that it should matter, but i am also using JqueryMobile 1.4.3. Any idea on how to fix this i did not see any settings that i had to change.

thanks for any input...

Can hooks be added for this setting to the toggled in the app? Android's flags prevent screenshots from being taken by the user and it would be nice to allow an option for users to disable this function.

Hello @devgeeks thanks for such a great plugin. We have a confirmed issue where we have an app with privacy screen plugin installed our input fields are acting up. When users tap in an input field - field receives focus but keyboard does not open. The only way to get a keyboard up is to double tap on the input field.

This is happening on multiple ios versions - 9.3 and 9.2.1

If I remove the plugin inputs in the app behave normally - user taps on an input and keyboard appears. If i add the plugin back in the issue is back.
Plugin versions that seem to cause the issue 0.1.3 and 0.1.2

Sample Code that illustrates the problem

Logs taken while reproducing problem

When ios application runs on landscape mode on iphone 5, 5s, 6, 6s device, when privacy screen is displayed, it shows an blank screen.

However, notice in the same testing, the splash screen just shows the portrait splash image. Although the portrait image is shown in landscape mode, it is still better than showning a blank screen to user.

When comparing the getImageName method in CDVSplashScreen.m has the below code:

if (device.iPhone5)
{ // does not support landscape
imageName = [imageName stringByAppendingString:@"-568h"];
}
else if (device.iPhone6)
{ // does not support landscape
imageName = [imageName stringByAppendingString:@"-667h"];
}

while in PrivacyScreenPlugin.m it has an extra check in the same code

if (device.iPhone5) { // does not support landscape
imageName = isLandscape ? nil :[imageName stringByAppendingString:@"-568h"];
} else if (device.iPhone6) { // does not support landscape
imageName = isLandscape ? nil : [imageName stringByAppendingString:@"-667h"];
}

A simple fix would be just remove the isLandScape?: condition check as CDVSplashScreen.m does.

Thanks
Jonathan

How to reproduce:
Open app -> lock screen -> turn device 90° -> unlock screen -> deformed privacyscreen image

Locking the device when the app is opened will cause the privacyscreen to be the last active screen from the app.

I have the following test which makes my app unusable. If the user use their control menu in portrait-mode or landscape-mode. Closes it. Then rotates to the other mode and opens it again it will result in a black screen. I will look tomorrow with a native developer maybe he can help me pinpoint it further. When i don't use this plugin it doesn't happen.

Can we have splash instead of black?

Its not working in android. We are seeing a dark screen instead of splash screen when switching between the apps in Android.

I am developing app on ionic, I used PrivacyScreen Plugin to view splash screen on multitasking. But the splash screen also shown in TouchID popup, I want to disable this splash screen for particular screen or TouchID popup.

Any Idea ?

Im using a Nexus 4 with Android 4.3 and this isnt working at all

Hello, all.

The plugin is working fine on Android app but on IOS 9.3.2 is not working.

Anybody with this issue too?

Many thanks.
Fernando.

How to edit toast msg? thanks

for a better control, I think you should add

• option to enable the plugin
• option to disable
• event or some return value to detect that user makes a screenshot and prevented -> so we can give the user some feedback
• some kind of callback function (success, error) for enable and disable options.

Hi there,
I used this plug in for my app and test it both on android and ios. Android works perfectly great , no screenshot can be taken but for ios it still can screen capture.My IOS version : 8.4.1
Is there anyway to fix this?or any suggestion?

It would be nice if there would be an image displayed instead of a black screen. Or much nicer than everything would be an iOS-Style Blur (like in PayPal App). But I´m using Phonegap Build and therefore can`t change the Plugin source...

Dear @devgeeks,

it will be great, If we can see all changes (small or big) in CHANGELOG file. Especially if there are breaking changes.

thank you very much!

I used this plugin in my app, and it works, it blanks page view when it is in background (task manager is open).
I'd like to show a splashscreen in the page area, instead a white page. Is it possible for Android?

Thank you very much!

I'm using Mobile Center to test the app, but the privacy plugin shows a black screen only.

Hello,

We have a requirement to block the multitasking thumbnail but on Android, this also prevents manual screenshots. This hinders regular use as well as popular screen sharing capabilities

Is it possible to allow Android to take manual screenshots but block the multitasking thumbnails?

Expected Behaviour

It should show black screen when recording screen with Media Projection API.

Actual Behaviour

The secured content visible when recording screen with Media Projection API.

Reproduce Scenario (including but not limited to)

Steps to Reproduce

Download a Screen Recorder app and start recording. You can see it is clearly capturing the screen.

Plugin version

Screenshot

Version in plugin.xml still 0.1.3 while in package.json it updated to 0.3.0

The plugin tries to load images with names like "Default-667h", etc. If I provide the name of the image in "UILaunchImageFile" it still adds suffixes like "LaunchImage-800-667h".

I added <splash ..> in config.xml, but it modifies versions of "LaunchImage" in "Images.xcssets". But, the plugin does not uses "LaunchImage" it tries to load "LaunchImage-800-667h" which is obviously missing.

I have no idea how to make it work - how to provide custom image that will be used to capture the screen.

I thought PrivacyScreenPlugin applied iOS7 means iOS version(something like 10.2.1).
I tested this on iPhone 5s (10.2.1) but this wasn't work properly, and just normal screenshot works well. (but android works fine)

Is there anything I miseed? or old iPhone 5 or 6 isn't applied for this module?

What I want is just black screen or any protection from the screenshot on my app.

Thanks.

Hi @devgeeks
First of all thank you for this plugin it works except that switching back from the app does not hide the splash screen.

Steps to reproduce.

1. Open the app.
2. Move the app to background by tapping home button
3. Tap the app again

Can you add support landscape mode?

Not sure if this is within the scope of this plugin but another security concern in Android is 'Tapjacking'. An easy fix for this is to set the filterTouchesWhenObscured property on the view object. This could be done in the plugins initialise method, like so:

  @Override
  public void initialize(CordovaInterface cordova, CordovaWebView webView) {
    webView.getView().setFilterTouchesWhenObscured(true);
    super.initialize(cordova, webView);
    Activity activity = this.cordova.getActivity();
    activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_SECURE);
  }

I could create a separate plugin for this, but I think it fits pretty well in here and adding it to this plugin would be slightly more convenient. Happy to create a pull request if you think this make sense.

Let me know what you think!

Is there a specific location where the "screenshots" are (temporary) stored? Or are the screenshots in-memory and discarded as soon as the app is closed from the switcher? Regardless of my questions; excellent plugin!

Hi there,

I just tested this with cordova 6.0.0 and the screen is always black.

To reproduce, install cordova 6.0.0 (the latest version), then:

cordova create Test
cd Test
cordova platform add ios
cordova plugin add cordova-plugin-privacyscreen
cordova emulate ios --target=iPhone-6-Plus

Cordova creates the HelloCordova app, which has (inside of the Xcode Project Resources) an Image.xcassets catalog including AppIcon and LaunchImage.
The image names in the LaunchImage catalog are standard: Default.png, Default-736h.png etc.

So I was expecting, leaving as is, that the privacy screen plugin would find the default*.png files and use one of them for the privacy screen, instead of the black screen, but it seems it can't find the images.

I tried to edit the HelloCordova-info.plist file and add the following:

    <key>UILaunchImageFile</key>
    <string>LaunchImage</string>

I've put LaunchImage, as that's the name of the image set. I tried to put Default.png, I tried Default. I tried add an image called Splash.png directly in the Resources folder of the Xcode project and tried to use Splash.png, or Splash.

When I press 2 times the "Home" button (I actually do that in the simulator by pressing Cmd+Shit+H 2 times), or when I resume the app after putting it in background, I always get the black screen instead of the splash image I was expecting.

I tried also to modify the plugin .m file and in the GetImageName to return "LaunchImage" or "Splash" but when I minimize the app and check it, it always has a black screen and not the splash screen.

It would be nice if you test this and maybe tell what I'm doing wrong or find a fix, thank you.

Expected Behaviour

The Splash screen needs to be shown

Black screen is shown
