Why i can’t remove my topic

[Life_Circuits]

I have been getting this error report whenever i try to switch screens in My App. My Phone Pops a warning saying that my app keeps stopping, and it asks me to send Bug report to Mi (xiomi) for analysis. I have been working on this app for quite a while now and i am not being able to use it properly. Please help me. I am much obliged.

Thank You.

The above Screen Shot is the Summary of the Error as Provided By my android device.

The .apk file is useless, compared to an .aia export.

Here are some conjectures you can test ...

• You fail to close screens as often as you open them.
• You have many Image components, failing to reuse single Image components with different picture files.
• You loaded up your Media folder with high resolution image files, which AI2 struggles to downgrade to fit your screen.

Good Afternoon, Believe we have found a bug while using the ios version of AI companion that does not occur with the android based device. While testing this code: on the ios device all image sprites immediately jump to the current x y location regardless of which sprite is dragged. This does not happen with android devices as the sprite will only move when selected.

This might also be a common case of Sprite Cannibalism.
Your blocks lack the additional code needed to avoid it.

Version 2.64 build 2 is struggling to show certain images. I am using PLTW lesson 1.7 Game time. The game sprites are not showing. When I use version 2.60 build 8, the game sprites show up.

[Michael_Provenzano]

I'm experiencing the same issue with PLTW Lesson 1.7 Game Time. I have noticed that, in addition to the sprites not showing up, the canvas also covers the horizontal arrangement above it. We are using iPads that are on version 2.64 (build 2) as well.
