I created an app that uses Firebase DB. But it keeps breaking down. I tried everything, but it keeps breaking down. Please help me. There is no problem with the code. Because even though I erased all the code, the crash continued.
As soon as you come to this screen, the compenion and the app collide. The other screens were asymptomatic and the same was true when the block was erased.(Debug failed to even try.)
Why are you using 4 firebase components? Are you calling data from 4 different firebase projects? If only one project then you really only need 1 firebase component.
Are you able to temporarily convert your aia project to English language and output all the blocks, this will make it easier for most people here to debug and help.
The screen is divided into several parts, adding several fire base DBs to simplify coding. I will change all blocks to English additionally.
turtle_school_copy_copy1_a_copy.aia (39.2 KB) I don't know if I translated well because I am not good at English. (The screen with the problem is Screen2.)
Not sure where the problem is, even removing all the blocks from their calls / screen initialise, when moving from Screen1 to Screen6 in companion crashes the companion.
Hi
I suggest:
- tidy-up the code, there should be no empty puzzle pieces
- Build an APK and record what happens using LogCat:
Capturing Device Logs using adb logcat
