[Camera] Demo crashes / hangs after clicking the start button

[Elinulok32]

Hello, thank you so much for adding this great camera component. I'm testing the camera demo on android 10, using Delphi 10.3.3. The demo compiles and install well on my android phone but crashes or hangs as soon as I click on the start button. At the first time of install it crashes after you grant permission to use camera and on subsequent runs it crashes just after clicking the start button.

Also, it was only able to compile and installed well, because I ignored the errors: "Error reading LocationSensor.ActivityType: Property ActivityType does not exist" and "Error reading LocationSensor.UsageAuthorization: Property UsageAuthorization does not exist" while opening the CD.View.Main.pas file in the IDE

Please is there anything I'm doing wrong? Thank you.

You're not doing anything wrong - it crashes for me too when compiling with 10.3.3. At the moment I can only suggest using 10.4.1. This may take some time to resolve.

Thank you very much for your rapid response. I will consider your suggestion. Thank you

@marlonnardi What you've reported is actually a new issue. Please refer to: https://github.com/DelphiWorlds/Kastri/issues/24

[DelphiWorlds]

To clarify, the crash happens when using Delphi 10.3.3, and causes this exception: EJINIException java.lang.IllegalArgumentException: Surface was abandoned I am yet to find a solution for it.

[tiagoomoreira]

Dear, I look forward to a solution to this problem. My App depends a lot on your camera. In advance I thank you for existing. I would like to participate in your project! I used the example of EXIF's for reading and ended up finding how to write EXIFs as well. It is a pity that Delphi does not care about these features. I also need a way to record videos taking the exact moment when the recording starts. I am studying alternatives for this.

[DelphiWorlds]

Unfortunately, I was unable to resolve this issue. Now that Delphi 10.4.2 Community Edition has been released, I am closing the issue, and advise users to upgrade

[Elinulok32]

Well noted and thank you so much. I'll upgrade to 10.4.2.
