Android Question CLOSED - LoadBitmapResize problem - never returns

When I use LoadBitmapResize on the attached bitmap it just hangs

B4X: 
                    NewTitleBitmap.TitleBitmap = LoadBitmapResize(Path, FolderFile, 40dip, 40dip, True)

If I just Open the bitmap with Paint.Net and SAVE it the size changes from 345kb to 1.2meg but then LoadBitmapResize works just fine.

THIS is the only bitmap (of 600+) that has ever given me a problem.

Very suprised the LoadBitmapResize did not fail or throw an error but just never returns

Interesting. I will make a test program and try it on all my devices (they are all Samsung)
Android v5.1.1 - v8.0.0

What Android version did you run on? and I guess B4A version and Java

I am still on B4A 9.90 and Java jdk-11.0.3 and using SDK settings - <uses-sdk android:minSdkVersion="5" android:targetSdkVersion="28"/>

I guess all these matter

nexus 5x 8.10 9.90 java 8.xxx same sdk settings. no emulator? i was a little confused by your initial post. first you say loadbitmapresize() hangs, then below that you say loadbitmapresize() loads just fine. i vote for the code that lets loadbitmapresize() load just fine

Here is a test program I wrote and the Folderbad.jpg (can't upload the good folder too large)

Has the actual directory I am loading from. Hangs (fails) / Never returns every time.

This is on a Samsung Galaxy Tab A SM-T580 Running Android 8.1.0

No sure what is happening. But strange that some have been able to load this.

i have some issues with the way you handle the runtime permissions, so i would have to modify.
it would be helpful to have the actual image. i'm guessing now106 is a radio station's website. can i download the original from there?
please advise exactly what "/storage" is. accessing direxternal this way is not how we're supposed to do it. please confirm where and what it is. tks.

NOTE - this is just a test program I made to see if anyone else could reproduce the error. Sorry that you don't like the way I handled the permissions. But I just cut and pasted enough code to get the test to work, not trying to make a app here.

106 is a CD cover image. Only copy of it I got was uploaded. With program.

Can't say where I downloaded from, just searched web or it automatically came when ripping CD Can't remember

Forgot to add Storage is a micro SD card 256gig

I don't think anybody can test your program exactly like you have it with a folder name like this:
"/storage/3338-6531/Music/Various Artists/Now That's What I Call Music!/Volume-106"
Your runtimepermissions code is very complicated , so I simplified it and here is the full code that works. I can attach the project if you like, but it is self explanatory
B4X: 
Sub Globals
    Dim fname2 As String 'the file needs to be in the assets folder: "Folder-Problem.jpg"
    Private imageview As ImageView
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("1")    'has imageview
    fname2 = "Folder-Problem.jpg"
    Dim rp As RuntimePermissions   'need runtimepermissions lib cheched
    rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)
    wait for Activity_PermissionResult(Permision As String, Result As Boolean)
    If Result = False Then
        MsgboxAsync("No permission to access external storage", "")
        Return
    Else    
        Log("granted permission")
        If File.Exists(File.DirRootExternal, fname2) =False Then
            File.Copy(File.DirAssets,fname2, File.DirRootExternal, fname2)
            Log("file copied to dir external")
            imageview.Bitmap = LoadBitmapResize(File.DirRootExternal,"Folder-Problem.jpg", 40dip, 40dip, True)
        End If

    End If
End Sub
I used the same file you were having trouble with, but found no problems

Yeah I am sure of that.

But if you have micro SD card you can create the sub directories under it "/Music/Various Artists/Now That's What I Call Music!/Volume-106" and then it is just a matter of what the prefix is to get to your SD card

Just got around to testing the test program on on my S7 (kind of same path /storage/3864-6563 device number is different after storage) and WORKS Fine.

So must be something with the Tab A SM-T580 (not sure what it could be) I will look into this more if possible.

Was thinking maybe storage read error, but then I deleted the file and copied a good file there and then recopied the bad file and it still happened so not likely that

This thread should not be closed yet. If the OP is using a micro SD card, then he is using an external removable storage. It has nothing to do with File.DirRootExternal or runtimepermissions. He needs to use the class here:

ExternalStorage - Access SD cards and USB sticks

Before we start: External storage means a real sd card or a connected mass storage USB device. This class can also be used to access the secondary storage (File.DirRootExternal). This becomes relevant with newer versions of Android that restrict direct access. It has nothing to do with runtime...

Here is an excerpt of the first paragraph:
1. External storage means a real sd card or a connected mass storage USB device.
2. It has nothing to do with File.DirRootExternal / DirDefaultExternal which actually point to an internal storage.
3. It has nothing to do with runtime permissions.
4. You can use RuntimePermissions.GetAllSafeDirsExternal to directly access a specific folder on the SD card.
