Android resource linking failed

[WORLD8848]

Hello. I am checking the usability of OneUIProject/oneui-design.

I did the test as follows.

1. Below, the dependencies portion is annotated on build.gradle(:sample-app) and build.gradle(:lib).

   // implementation("io.github.oneuiproject.sesl:appcompat:$sesl_appcompat_version") // implementation("io.github.oneuiproject.sesl:material:$sesl_material_version") // implementation("io.github.oneuiproject.sesl:recyclerview:$sesl_recyclerview_version")

2. I generated the aar file with the assembleRelease command for each unit module in OneUIProject/sesl. The aar files were then included in Sample-app, lib via the Implementation files command.

3. Gradle sync now runs successfully.

4. When I run the sample-app, an error occurs as below.

Please give me some advice to solve these errors. Thank you.

As I already told you, you don't have to build the aars, adding the dependencies is already enough: your IDE will download the binaries from the maven central repository. Try to build the app without modifying any file (just by cloning the repo in your PC and opening the project) and let me know what happens

[WORLD8848]

Thank you from the bottom of my heart for your reply.

I am interested in the various usability of the open library, so I am trying various things. And I shared some simple experiences.

Wouldn't this experience make a better library?

I will share it here when a good solution is found.

Again, I don't see why you should compile the artifacts if you didn't do any modifications to them. Also, the way you added the dependencies in your project will not import the .aar files you compiled but instead will download them from the maven repo, to import your custom .aars you actually have to use this line:

dependencies {
    //implementation 'io.github.oneuiproject.sesl:appcompat:1.0.0'
    //implementation 'io.github.oneuiproject.sesl:material:1.0.0'

    implementation fileTree(include: ['*.aar'], dir: 'libs')

}

This will import all the .aar libraries inside your project's "libs" folder. Regarding the build error, seems like something's off with the material library (the missing attrs are from that lib). Could you send me your app/build.gradle file so I can see if there's something off in it?

Thanks!!

I fully understand how to use the library you shared.

I share the requested information.

Everything seems fine (you don't need to import every .aar file since with that one line I told you to add it does add all of them automatically). Are you still having the same issue?

[WORLD8848]

The result is the same even if you annotate the bottom part.

implementation files('libs/AppCompat-1.0.0.aar') implementation files('libs/AppPickerView-1.0.0.aar') implementation files('libs/CoordinatorLayout-1.0.0.aar') implementation files('libs/Core-1.0.0.aar') implementation files('libs/CustomView-1.0.0.aar') implementation files('libs/DrawerLayout-1.0.0.aar') implementation files('libs/Fragment-1.0.0.aar') implementation files('libs/IndexScroll-1.0.0.aar') implementation files('libs/Material-1.0.1.aar') implementation files('libs/Picker-Basic-1.0.0.aar') implementation files('libs/Picker-Color-1.0.0.aar') implementation files('libs/Preference-1.0.0.aar') implementation files('libs/RecyclerView-1.0.1.aar') implementation files('libs/SlidingPanelLayout-1.0.0-Alpha01.aar') implementation files('libs/SwipeRefreshLayout-1.0.0.aar') implementation files('libs/ViewPager-1.0.0.aar') implementation files('libs/ViewPager2-1.0.0.aar')

Did you try to compile the original project without any modification as I suggested?

[WORLD8848]

I tried compiling the Original Project without any modifications to the contents mentioned above.

Below is an image with an error message.

Therefore, the following contents were added to the dependencies section of the build.gradle(:lib).

import androidx.activity.OnBackPressedCallback;

Then, the above-mentioned [Android resource linking failed] error occurs.

[salvogiangri]

Did you check if this error could be caused by the nonTransitiveRClass flag like it did in the old library?

[salvogiangri]

I totally forgot about the most stupid thing we could've tried😂: try to add the androidx cardview dependency in your build.gradle file:

implementation 'androidx.cardview:cardview:1.0.0'

[WORLD8848]

The above has been reflected.

The above has been reflected. Then, a new error appeared.

I am sharing the relevant information with the image below.

Thank you.

Did you check if this error could be caused by the nonTransitiveRClass flag like it did in the old library?

gradle.properties

add: android.nonTransitiveRClass=true

A new error occurs that is different from the above mentioned error

[salvogiangri]

I think I found your issue: you're still using custom built .aars in your project, in this way you have to manually declare all the dependencies of each sesl lib module on your build.gradle files. As I said, try to avoid using custom .aar files and use the artifacts in the maven repository. If you still wish to use custom artifacts I suggest you to compile the sesl library using the maven local repository instead
