Android Question DJI error

PABLO2013 · Jan 13, 2021

Greetings, I have reinstalled my programs but I still continue with this error and I do not know how to fix it, thanks.

MarcoRome · Jan 13, 2021

If you read:

Sub activity_permissionresult was not found

This is error

PABLO2013 · Jan 13, 2021

Thank you very much, but excuse me, how could I solve it

You are calling Activity_permissionResult in the delgate

line 55 in main needs to be :

B4X:

b4xpages.Delegate.B4xPage_PermissionResult(Permission,result)

PABLO2013 · Jan 13, 2021

tks, Andrew
but b4xpages.Delegate.B4xPage_PermissionResult(Permission,result) is a unknown member (b4xpages 1.07)

Andrew (Digitwell) · Jan 13, 2021

could it be this?

[FIXED] [B4X] B4XPages - problem with Permissions (not CloseRequest as thought)

I'm playing with CloseRequest which I have placed in B4XMainPage on the ThreePagesExample project. This is an Android 10 device. 'Return True to close, False to cancel Private Sub B4XPage_CloseRequest As ResumableSub Dim sf As Object = xui.Msgbox2Async("Close?", "Title", "Yes", "Cancel"...

my mistake you should not be changing anything in the Main Delegates.

PABLO2013 · Jan 13, 2021

I'm sorry if it's me, but I don't understand you, thanks

Delete the application before installing it, but now I get this error

Erel · Jan 14, 2021

Please post code and logs as text.

First step is run the example. Does it work for you?

PABLO2013 · Jan 15, 2021

1. Windows 8.1 64, phatom 4 pro v1, ba4 10.5, java 11 , Tablet Shield Android 7.0

2. The application is your example without any modification

3. The application has two bugs at the moment:

A. Failed to delete the application and reinstall it (Release mode)

4. The application, despite the failures, does not fall but once I connect it to the drone control it falls.

5. As I repeat, the application has no communication with the drone and on the contrary it falls

6. I appreciate the help ,tks.

What is the version of the DJI library?

Erel · Jan 15, 2021

I have a feeling that you are using an old version of RuntimePermissions. Uninstall B4A. Make sure that the installation folder was deleted and reinstall it.

There was a bug in an older version where the PermissionResult was raised in the wrong place in some cases.

PABLO2013 · Jan 16, 2021

thanks, greetings, reinstalled b4a and indeed I had an outdated runtinepermissions library, now the versions are 1.12 and dji 4.6, but now the error is this:

On the other hand this is my application, for which I need to do tests, but the errors do not let me continue.

Erel · Jan 17, 2021

Try the compiled example: www.b4x.com/android/files/Drone.apk

Check the logs.

PABLO2013 · Jan 19, 2021

greetings, thanks for all your help. I did not know how to do the requested log, I made a capture, the application that you sent me does not work.
