Android Question Dex merg error defined multiple times

[Hosein_Mghr]

Hello, dear friends.
I encounter this dex merg when compiling. Description,
When from the Firebasenotifictin library
I use a special library called Dexter
I get dex merg error when I remove Firebasenotifictin library the problem is fixed but I have to use Firebasenotifictin and Dexter library together if anyone can help I would be very grateful


Error Is : c:\android\tools\..\extras\b4a_local\unpacked-core-1.3.2.androidx-63826323194241\jars\classes.zip:classes.dex:
Type android.support.v4.os.ResultReceiver$1 is defined multiple times: c:\android\tools\..\extras\b4a_local\unpacked-core-1.3.2.androidx-63826323194241\jars\classes.zip:classes.dex, c:\android\tools\..\extras\b4a_remote\androidx\core\core\1.3.1\unpacked-core-1.3.1\jars\classes.zip:classes.dex
Compilation failed

From
MultiDex: True
I also used it, but the problem was not solved. Can anyone solve the problem?

I use a special library called Dexter

Why? What it does?

 

[Hosein_Mghr]

Get access permissions With Dexter

 

[Hosein_Mghr]

چرا؟ چکار میکند؟

#AdditionalJar: com.android.support:support-v4

Can this fix the error?

 

[Erel]

Get access permissions With Dexter

Use RuntimePermissions.

 

[Hosein_Mghr]

Use RuntimePermissions.

In general, I use different libraries that seem to be old, but they work well, but after adding the Firebasenotifictin library, I still get Dex merg error. What do you suggest to solve this problem?

 

[Erel]

Correct solution is to remove unneeded libraries and use proper ones.

You can try this:

#ExcludedLib: core-1.3.1

 

[zed]

Maybe add this

#MultiDex: True

The problem is not fixed and I am facing another error again. Do you know what it is?

You are wasting your time. Remove the libraries that cause the problem and use proper libraries.
