Android App Black Box

ShiffShiff Junior Member

I am having an issue with the 1Password Android application turning black when it is launched on an external monitor connected to the Pixelbook. The application UI is just a black box. I can move the app, minimize the app, maximize the app, etc. It is not locked up as I can move it around. I do not believe this is only a problem with 1Password as some other Android apps do it as well. It is also not all Android applications as some work fine. Google Android apps also work just fine so far. I am not sure if this is an issue with Chrome OS itself or some type of scaling issue of some Android apps.

This only occurs if I launch 1Password on the external display. It is running at a resolution of 2560 x 1440. However, it happens at any resolution on the external display. If I launch the application on the Pixelbook itself, the application runs fine. In fact, the new 1Password update I installed today runs even better on the Pixelbook.

I can workaround the issue by simply opening the application on the Pixelbook screen instead of the external monitor. It works fine as long as it is not opened on the external monitor.

Just pointing it out in case anyone else has the issue.

    Hi @Shiff. Thanks for reporting this issue to us. Can you let me know what version of 1Password you're currently using? Also, would you be willing to install the beta version and let me know if you see the same problem there?

    Sure, I will sign up and install the beta.

    The version of 1Password for Android that I have installed is 6.8.

    I installed the beta 7.0 BETA-7 and notice the same behavior. The application launches and runs fine on the Pixelbook screen. It launches black on the external monitor. In fact, I can launch it on the Pixelbook screen and as soon as I drag any piece of it to the external screen, that piece turns black.

    Hey @Shiff, I'd be happy to jump in and help you out here. I'll start with the how...

    It is possible to work around the issue by enabling screenshots in 1Password:

    1. Launch and unlock 1Password
    2. Tap on Settings and then tap on Advanced
    3. Tap on Allow screenshots and then tap exit when prompted

    After following those steps, you should be able to now use 1Password on the external monitor.

    Now for the why... We set a special flag to ensure that what is displayed on screen in 1Password is not visible to any other apps on your device. When this flag is enabled, Android hides the contents of the 1Password in the recent apps list and blocks any attempts at screen capture or recording. It appears that the Android environment on Chrome OS is also extending this to include external displays.

    Given that Chrome OS is currently running Android Nougat, and that Oreo added extended support for multiple displays, I think that we can expect external display support for Android apps to continue to evolve on Chrome OS. I hope that helps to explain what you're seeing and give you enough information to decide whether you want to use the work around above. Let me know if you have any questions!

    Thank you @mverde . That solved my issue.

    Due to this being a Chromebook that I am managing with Chrome Enterprise inside my personal GSuite account, I am fine with the slight risk enabling this poses. I appreciate there being an option so I can keep it disabled on devices that I, personally, do not control.

    Thanks! Glad to hear that helped. Looking forward to seeing where Google takes Android and Chrome OS in the future. :chuffed:
