vincentehsu · Jan 14, 2015

Dear Sir:
Attachment is my project use for down .apk file from server and savt to sd card,I have some problems as below:
(1)I got the sd card file path(Check my project)

B4X:

/storage/extSdCard/Android/data/b4a.samples.downloadservice/files

if i used below code,then i can see the file in my phone's sd card path

B4X:

File.WriteString(Path,"Agree.txt","Agree")

my issue is when jobdown finish,I can't see tmp.apk file in my phone's sd card

B4X:

Sub JobDone (job As HttpJob)
   Log("JobName = " & job.JobName & ", Success = " & job.Success)
   ProgressDialogHide
   If job.Success = True Then
      Select job.JobName
      Case "job2"
            Log(Path)
            If File.Exists(Path , "tmp.apk")=True Then
                File.Delete(Path,"tmp.apk")
            End If
            MyStream = File.OpenOutput(Path, "tmp.apk", False)
            MyStream.InitializeToBytesArray(1)
            File.Copy2(job.GetInputStream,MyStream) ' save the file
      
Dim iIntent As Intent
            iIntent.Initialize(iIntent.ACTION_VIEW, "File://" &  Path & "/tmp.apk")
            iIntent.SetType("application/vnd.android.package-archive")
            StartActivity(iIntent)

        End Select
    End If
    job.Release
End Sub

(2) when i exe the code as below,i got parser error,it's cause of the file not exist in my sd card path or something miss?

B4X:

Dim iIntent As Intent
            iIntent.Initialize(iIntent.ACTION_VIEW, "File://" &  Path & "/tmp.apk")
            iIntent.SetType("application/vnd.android.package-archive")
            StartActivity(iIntent)

Dear DonManfred:
I've change my code as below,and the path shown as "/storage/emulated/0"

B4X:

Sub JobDone (job As HttpJob)
   Log("JobName = " & job.JobName & ", Success = " & job.Success)
   ProgressDialogHide
   If job.Success = True Then
      Select job.JobName
      Case "job2"
            Log(Path)
            If File.Exists(File.DirRootExternal , "tmp.apk")=True Then
                File.Delete(File.DirRootExternal,"tmp.apk")
            End If
            MyStream = File.OpenOutput(File.DirRootExternal, "tmp.apk", False)
            MyStream.InitializeToBytesArray(1)
            File.Copy2(job.GetInputStream,MyStream) ' save the file
           
            Dim iIntent As Intent
            iIntent.Initialize(iIntent.ACTION_VIEW,  File.DirRootExternal & "tmp.apk")
            iIntent.SetType("application/vnd.android.package-archive")
            StartActivity(iIntent)
        End Select
    End If
    job.Release
End Sub

i got an error

as i know,the apk file we want to set up shoule be store at sd card,right?

DonManfred · Jan 14, 2015

check your paths!
/storage/emulated/0tmp.apk

this file do not exist

Erel · Jan 14, 2015

Your code is wrong.
It should be:

B4X:

iIntent.Initialize(iIntent.ACTION_VIEW, "file://" & File.Combine(File.DirRootExternal, "tmp.apk"))

vincentehsu · Jan 14, 2015

B4X:

Sub JobDone (job As HttpJob)
   Log("JobName = " & job.JobName & ", Success = " & job.Success)
   ProgressDialogHide
   If job.Success = True Then
      Select job.JobName
      Case "job2"
            Log(Path)
            If File.Exists(File.DirRootExternal , "tmp.apk")=True Then
                File.Delete(File.DirRootExternal,"tmp.apk")
            End If
            MyStream = File.OpenOutput(File.DirRootExternal, "tmp.apk", False)
            MyStream.InitializeToBytesArray(1)
            File.Copy2(job.GetInputStream,MyStream) ' save the file
           
            If File.Exists(File.DirRootExternal , "tmp.apk")=True Then
                Log("True")
            End If
           
            Dim iIntent As Intent
            iIntent.Initialize(iIntent.ACTION_VIEW,"file://" & File.Combine(File.DirRootExternal, "tmp.apk"))
            iIntent.SetType("application/vnd.android.package-archive")
            StartActivity(iIntent)
        End Select
    End If
    job.Release
End Sub

file is exist, but i got another error from StartActivity(iIntent)
parsing the package error,it's cause the file not in external storage(SD card)?

Erel · Jan 14, 2015

Have you tried this code? Previously you posted File:// instead of file://

vincentehsu · Jan 14, 2015

I've change to

B4X:

Sub JobDone (job As HttpJob)
   Log("JobName = " & job.JobName & ", Success = " & job.Success)
   ProgressDialogHide
   If job.Success = True Then
      Select job.JobName
      Case "job2"
            Log(Path)
            If File.Exists(File.DirRootExternal , "tmp.apk")=True Then
                File.Delete(File.DirRootExternal,"tmp.apk")
            End If
            MyStream = File.OpenOutput(File.DirRootExternal, "tmp.apk", False)
            MyStream.InitializeToBytesArray(1)
            File.Copy2(job.GetInputStream,MyStream) ' save the file
           
            If File.Exists(File.DirRootExternal , "tmp.apk")=True Then
                Log("True")
            End If
           
            Dim iIntent As Intent
            iIntent.Initialize(iIntent.ACTION_VIEW,"File://" & File.Combine(File.DirRootExternal, "tmp.apk"))
            iIntent.SetType("application/vnd.android.package-archive")
            StartActivity(iIntent)
        End Select
    End If
    job.Release
End Sub

i got an error

Erel · Jan 14, 2015

Please read my previous post again.

vincentehsu · Jan 14, 2015

I'm sorry i don't get it,is here?

B4X:

Dim iIntent As Intent
            iIntent.Initialize(iIntent.ACTION_VIEW,"file://" & File.Combine(File.DirRootExternal, "tmp.apk"))
            iIntent.SetType("application/vnd.android.package-archive")
            StartActivity(iIntent)

change to

B4X:

Dim iIntent As Intent
            iIntent.Initialize(iIntent.ACTION_VIEW,"File://" & File.Combine(File.DirRootExternal, "tmp.apk"))
            iIntent.SetType("application/vnd.android.package-archive")
            StartActivity(iIntent)

Erel · Jan 14, 2015

It should be file:// (not File://).

vincentehsu · Jan 14, 2015

yes,tks

B4X:

Sub btnDownload_Click
    job2.Initialize("job2", Me)   
       job2.Download("http://125.227.11.94/TMS/Files/APP1.apk")
    
End Sub
Sub JobDone (job As HttpJob)
   Log("JobName = " & job.JobName & ", Success = " & job.Success)
   ProgressDialogHide
   If job.Success = True Then
      Select job.JobName
      Case "job2"
            Log(Path)
            If File.Exists(File.DirRootExternal , "/tmp.apk")=True Then
                File.Delete(File.DirRootExternal,"/tmp.apk")
            End If
            MyStream = File.OpenOutput(File.DirRootExternal, "/tmp.apk", False)
            MyStream.InitializeToBytesArray(1)
            File.Copy2(job.GetInputStream,MyStream) ' save the file
           
            If File.Exists(File.DirRootExternal , "/tmp.apk")=True Then
                Log("True")
            End If
            Log(File.Size(File.DirRootExternal,"/tmp.apk"))
           
            Dim iIntent As Intent
            Dim k As String="file://" & File.DirRootExternal & "/tmp.apk"
            Log(k)
            iIntent.Initialize(iIntent.ACTION_VIEW,k)
            iIntent.SetType("application/vnd.android.package-archive")
            StartActivity(iIntent)
        End Select
    End If
    job.Release
End Sub

I still get package parsing error
so i check the file size and return 0,Why?is there something miss?

I think you are complicating things somewhere, the attached sample works (sorry but I don't use httputils, however you'll get the idea)
