Android Question exoplayer play video.mp4 file from usb device

fifiddu70 · Jun 27, 2024

Hi everyone, I'm creating an app for playing video.mp4 content with exoplayer and so far I've succeeded but only by loading the video files into the dirasset and therefore inside the Android device, as per the title I need to play some video files .mp4 not from the internal memory but from a USB stick connected to the Android device, can anyone help me, I post the code that I have created yet to be completed, I would like to point out that I have set the paths in dirrootexternal but as per the title I want to recall them from the USB.

Set targetsdk to 26 or 28 at max. It will NOT work with targetsdk=30+

See https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/ for more details.

That´s the baddest errordescription i´ve ever seen

If it does not work then there MUST be an Error. Post the FULL Stacktrace.
Best is to upload a small project showing the problem.

NO ONE can help without seeing what you are doing and how.

Use the ManageExternalStorage class and get permission to use the directory on the SDCard.

In the Main Activity Create, I use this to get the permissions and location of the SDCard directory:

B4X:

' These are declared in Process Globals

'    Dim MES As ManageExternalStorage
'    Dim Storage As ExternalStorage  
'    Dim RootDir As String                  


    If FirstTime Then
        MES.Initialize(Me, "MES")
        Storage.Initialize(Me, "storage")
    End If

    ' Get access to the SDCard
   
    If Not(MES.HasPermission) Then
        MsgboxAsync("This app requires access to all files, please enable the option", "Manage All Files")
        Wait For Msgbox_Result(Res As Int)

        MES.GetPermission
        Wait For MES_StorageAvailable
    End If

    ' Get access to the SDCard directory
   
    Storage.SelectDir(True)
    Wait For Storage_ExternalFolderAvailable

    RootDir = Get_URI_Dir(File.GetText(File.DirInternal,"PersistantUri"))
    Log("Using " & RootDir)

This sub reads the file created by ManageExternalStorage to parse out the directory so it is in the correct format

B4X:

'Get the directory path from the storage URI
Sub Get_URI_Dir(URI As String) As String
   
    ' content://com.android.externalstorage.documents/tree/13FA-1001%3AMovies
    ' to
    ' /storage/13FA-1001/Movies
   
    Dim RtnVal As String=URI
   
    Do While RtnVal.Contains("/")
        RtnVal=RtnVal.SubString(RtnVal.IndexOf("/")+1)
    Loop
   
    RtnVal=RtnVal.Replace("%3A", "/")
   
    Return "/storage/" & RtnVal
   
End Sub

RootDir ends up looking something like "/storage/13FA-1001/Movies"

Then load the file with

B4X:

player.Prepare(player.CreateFileSource(RootDir, "MovieFile.mp4"))

Add the following to the Manifest

B4X:

AddPermission(android.permission.MANAGE_EXTERNAL_STORAGE)
SetApplicationAttribute(android:requestLegacyExternalStorage, true)

This code works with android:targetSdkVersion="33" but is probably going to get blocked if you try to upload it to the Play Store.

In ManageExternalStorage.bas, the package name needs to be set. The version floating around has:

B4X:

' Be sure to reference your app package name in "pakageg:xxx"
    in.Initialize("android.settings.MANAGE_APP_ALL_FILES_ACCESS_PERMISSION", "package:b4a.example")

I changed the version I keep to :

B4X:

' Be sure to reference your app package name in "pakageg:xxx"
    in.Initialize("android.settings.MANAGE_APP_ALL_FILES_ACCESS_PERMISSION", "package:"  & Application.PackageName)

I also use the ExternalStorage.b4xlib library rather than the class file.
