zxing3.6.0 / support:appcompat-v7 error...

Description of the problem:

I try…

• Create New Project

• target sdk version 28, min sdk version 19

• compile sdk version 28

• insert gradle dependencies : implementation ‘com.journeyapps:zxing-android-embedded:3.6.0’

• implementation ‘com.android.support:appcompat-v7:28.0.0’ <-Error…

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 25.3.1. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:support-media-compat:25.3.1 less… (⌘F1) There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion).

How can fix…??? T_T

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.yoonho.jitest"

}

Which library version are you using? E.g. 3.6.0.

**Which phone/tablet are you using, and which Android version does it run? ** galaxy s4

Does the same happen on other devices or an emulator? same happen on other emulator

The main library is an aar file anyway, even without the @aar annotation. I suspect that specifying explicitly does roughly the same as this:

implementation('com.journeyapps:zxing-android-embedded:3.6.0') { transitive = false }

Which basically says “use this library, but none of its dependencies”.

Hi, I think the @aar annotation implements a compiled binary, while without that annotation it drops a copy of the repository to be compiled with your project and that’s where the error appears
