Android Question Error with syntax using JKSSH2 Lib

[Tyler]

Hey guys, I'm having an issue with quotes inside of quotes, hoping someone can help me. Here's my code:

"screen -S gmod1 -p 0 -X stuff " & "" & command.text & "" & "`echo -ne '\015'`"""

Basically this sends text to a Linux screen session and hits ENTER(I've also posted on UNIX forums due to it being partially a UNIX/SHELL Issue but I think the syntax issue relates to B4A). If command.text is only one word, it works perfectly fine. If I want command.text to be two words I must manually add quotations around them within the app. I would like to add the quotation programmatically. I'm also racking my brain on changing the variable before this line of code. Something to the affect of

command.text = """ & command.text & """

But that won't work either as it puts "command.text" into the string.


I also tried using QUOTE &.... But that Didn't work either


Any help on this would be greatly appreciated as I'm almost done and don't wanna be shutdown by a silly syntax error.

command.text = chr(34) & command.text & chr(34)

or

command.text = """" & command.text & """"

Could've sworn I tried that.... At any rate, worked a charm! Cheers!

Now my next and final issue as the app is done but this keeps happening when not in Debug.

whenever the following code runs

ssh.Initialize("ssh", hostname.Text, port.Text)
    ssh.authenticateWithPassword(username.Text, password.Text)
    ssh.execCommand("screen -X -S gmod1 kill", 12)

I get android.os.NetworkingOnMainThreadException
Continue?


Any suggestions?

This library makes the network calls on the main thread. This is not allowed on Android 4.0. You can set android:targetSdkVersion to 4 instead of 14 to workaround this issue (in the manifest editor).

 

[Tyler]

Okay, that didn't seem to work.. I'm fairly noob-ish when it comes to manifest editor, would you be so kind as to post an example?

 

[DonManfred]

AddManifestText(
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="4"/>
<supports-screens android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:anyDensity="true"/>)

Oops, just noticed it in default lines in manifest. It would seem 16 hours of straight coding turned my brain to mush. I got it working though. How could I go about using httputils to do this instead?(due to SDK 4 being very old and kind of looks like crap).

 

[Erel]

HttpUtils2 will not help here. You can use the Threading library to make the calls with a secondary thread.

Another option is to disable the NetworkOnMainThread check: http://www.b4x.com/android/forum/threads/workaround-the-networkonmainthread-exception.44760/

I ended up using this code and it works regardless of SDK version(above 9).

Dim p As Phone
If p.SdkVersion >= 9 Then
  Dim r As Reflector
  r.Target = r.CreateObject("android.os.StrictMode$ThreadPolicy$Builder")
  r.Target = r.RunMethod("permitAll")
  r.Target = r.RunMethod("build")
  r.RunStaticMethod("android.os.StrictMode", "setThreadPolicy", _
      Array As Object(r.Target), Array As String("android.os.StrictMode$ThreadPolicy"))
End If
