From the IDE use File-Export as Zip. Upload this zip please.

Try to make the camera panel visible before you initialize CameraEx.

 

[Pat Fahey]

Change the code to make sure the layout is open.

but now

I'm getting the java.lang.reflect.invocationtargetexception saying it cannot open the camera services.

Any suggestions?

 

[Erel]

Can you post the full error message from the logs?

 

[Pat Fahey]

success = false, (RuntimeException) java.lang.RuntimeException: Fail to connect to camera service

Thanks everybody, it was a permissions issue.

You guys are awesome.

Hi,
How did you solve a permissions issue?

I am too using camerex and can't get past the camera_ready sub. I checked the variable success and returns false.
I am using LG K10 (2017)

When installing the application, the phone does not require camera permissions.

Please help.

Sub Process_Globals
  
    Dim rp As RuntimePermissions
  
End Sub



rp.CheckAndRequest(rp.PERMISSION_CAMERA)
    Wait For Activity_PermissionResult (Permission As String, ResultPermission As Boolean)
    Log(Permission)
    Log(ResultPermission)

The latest version of CameraEx example properly handles the permission: https://www.b4x.com/android/forum/t...tends-the-camera-library-functionality.23801/

Thank you for the answers.
But, when I add the RuntimePermission library (version 1.10) I have a compilation error:

B4A Version: 8.80
Parsing the code. (0.03s)
Building folders structure. (0.03s)
Compiling the code. (0.03s)
Compiling the layout code. (0.00 secs)
Organizing libraries. error
Maven artifact not found: com.android.support/support-v4

What should I do?
