Please confirm you are using theta-client 1.10.0 and the problem is occurring with the build to Android.

Successful Test with Android

I also tried running the demo-flutter on an Android simulator and was successfully able to display the app on the simulator. I’m using the Flutter version 3.22.3 on a Mac version Sonoma 14.6. I’m also using the Pixel Fold simulator on Android 15.

To run the application, I used my Mac’s home internet connection. I ran the command flutter run -d emulator-5554 which opened up the Android simulator with the Plugin example app. After the application showed up, I disconnected my Mac’s internet connection and connected it to the WiFi from the Theta X camera, allowing it to connect to the camera.

The terminal shows that the demo works as expected:

I tested the Take Picture, File List, and Capture Video command which appeared to work appropriately.

Successful Test with IOS

The demo-flutter also works on an iOS simulator as expected. I used the iPhone 15 simulator on version 17.5 and went through the same process to run the device on iOS.

Using theta-client version 1.10.0

This last test done with Arch Linux on the desktop.

Previous two tests were down on MacOS (two different computers).

No problems on the three computers we tested.

Suggest you reinstall Android Studio and the Android SDK and use the version of Java from Android Studio. If problem persists, show the output of flutter doctor -v
