Android Question [SOLVED]The compilation was successful but an error occurred after b4a-Bridge received it

[Jones Hone]

I use B4A-Bridge v2.67 to connect to my phone. Compile using Release Mode.
I compiled successfully without any error messages.

B4A Version: 12.50
Parsing code.    (0.33s)
    Java Version: 19
Building folders structure.    (0.05s)

Signing package file (debug key).    (0.58s)
Installing file to device.    (0.06s)
    Installing with B4A-Bridge.
Completed successfully.

However, b4a-Bridge immediately displays the following message after receiving it.

剖析套件時發生問題 (A problem occurred while parsing the package(My phone is in Chinese so I translated the message))
(This message appears before the installation starts, and then it ends)

Although I have #Bridgelogger: True, no message appears.

My phone is Redmi Note 9, Android 12.
This APP has been used on this phone for 2 years. This APP has not been changed for about half a year. I want to modify it today but this problem appears before I modify it.
I have also used this environment to develop other apps recently, and everything is normal!
Because there is absolutely no error message, I really don't know where to start troubleshooting.
Can someone help me where to check? Thanks!

Don't check this. You will see all possible problems.

The Logs Windows is no any message!
Because my APP had an error before it was installed!
So the app was not installed successfully and has not yet been executed.

Try to change targetSdkVersion to 31 or below

 

[Jones Hone]

change targetSdkVersion to 30, It can be installed,
but a strange error occurs when executing!
It has already been initialize, but it says object first be initialized!
Don’t know what the problem is?

 

[teddybear]

It has already been initialize, but it says object first be initialized!

Apparently, File.ListFiles is failed, what is AppPath?

 

[Jones Hone]

AppPath is a variable whose content is a valid and existing path name.
The app was not given read and write permissions. After granting them, everything worked fine.
But another error occurred!
Let me research what the error is!
If I can't solve it, I'll ask you guys for help!

熊辉 謝謝您的指點!

 

[DonManfred]

It has already been initialize, but it says object first be initialized!

You need to understand how it works!
Yes, you initialized the Object but in the nextline your get and UNINITIALIZED list back as file.listfiles returns nothing.

For the topic of the thread, it has been solved by changing targetSdkVersion , this is another question, you'd better create a new thread for ask

You have to check if the list is initialized

    Dim DirS As List
    DirS = File.ListFiles(Starter.Application_ErrorPath & "/Bak")
    If DirS.IsInitialized Then    
        For i = 0
            ....
        Next
    Else
        Log("There was an error reading the path")
    End If

Thank you for your advice.
