Android Question SOLVED HTTP fails after simple manifest update to target 28?

[Unobtainius]

I'm not even sure where to start? I got the warning suggesting to update the manifest to targetSdkVersion="28"
So I did. Now a project that worked perfectly with it set to 27, fails when I set it to 28?
Please ignore &deviceid=unknown in my call, I would normally get a JSON error message back with device unknown, but in this instance it just crashes
All I have to do to get it all working as expected is to set the manifest back to 27.
I would like to use the latest one, so if someone could help me overcome this issue, it would make my day

after the manifest as below, the error still remains

AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="28"/>
<supports-screens android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"

Are you pointing to Android.jar of Android 28 in B4A Configure Path?

 

[Erel]

This error happens because you are using the deprecated HttpUtils2 library. You should switch to OkHttpUtils2.

 

[Unobtainius]

Ok thanks, I will give it a go tomorrow morning

 

[Unobtainius]

Works like a charm. Thank you very much and, sorry for bothering you when the library window clearly states HTTPutils has been depreciated
Sometimes one cant see the forest for the trees
Thanks again

 

[Alexander1981]

please I have updated the manifest
I use the OkHttpUtils2 library.
but it does not work

PageServer="http://example.com?field=valor"
Dim js As HttpJob
js.Initialize ("", Me)
js.Download (PageServer)
Wait For (js) JobDone (js As HttpJob)

Help me

 

[drgottjr]

more changes to your manifest; you have to add this:
SetApplicationAttribute(android:usesCleartextTraffic, "true")

[drgottjr]

check this link. it's not completelyl applicable, but about half way down it mentions 2 things:
1) networkSecurityConfig
2) a slightly different manifest change relating to "cleartext"

it also explains what's up with okhttputils2 and sdk 28 and a change google made that requires manually allowing "cleartext" over http.
the guy who was answering the problem is pretty high up the food chain here, and his reaction to "networkSecurityConfig" was the same as mine: where does it come from? if he doesn't know what it is, i certainly don't.

a little further down, a slightly different manifest addition is used regarding cleartext. you might want to try that one instead.

the reason you can't connect over http (versus https) with okhttputils and sdk 28 is because google basically turned it off. you have to expressly override it. i check one of my apps that is sdk 28 and has to use http. i added:

CreateResourceFromFile(Macro, Core.NetworkClearText)

to my manifest using this version. try this one instead.

sorry it's not getting better.

I´ve
B4A 9.80
Android 28
jdk1.8.0

CODE:
PageServer = " http://example.com?field=valor "
Dim js como HttpJob
js.Initialize ("", Me)
js.Download (PageServer)
Esperar (js) JobDone (js como HttpJob)


Nothing stays the same, it does not vote any error, but it does nothing
I need urgent help please

 

[drgottjr]

the code, as you show it, is not meant to do anything but download the page. if you want to see what was downloaded, you need:

dim PageServer as string = "[URL='http://example.com/?field=valor'][B]http://example.com?field=valor[/B][/URL]"
Dim js como HttpJob
js.Initialize ("", Me)
js.Download (PageServer)
wait for (js) JobDone (js as HttpJob)
if js.Success then                
   dim text as string = js.getString
  log ("GOT: " & text)
else                          
   log(lastexception.message)
End If
j.Release

also, it sounds like the issues relating to cleartext have been resolved, yes?

 

[Alexander1981]

The url is fine, that is only an example, my url I put it in a browser and if it returns the information

 

[drgottjr]

i don't care what the url is. the code you showed only downloads. it does not show the information. you need to add lines 6 through 12 as i wrote previously.

        Dim PageServer As String
