Problem Description
Hi All,
I am working on one Android App having 4 (Four) other modules (Library Modules) created by me e.g. lib_module_1, lib_module_2, lib_module_3 and core_api_lib_module. So far, I was using these library module in my app using project dependency as below--
implementation project(":lib_module_1")
implementation project(":lib_module_2")
implementation project(":lib_module_3")
implementation project(":core_api_lib_module")
in this case my app is working fine, but now I got one requirement to use equivalent (.aar) files for the same modules instead of these actual library modules for the code management purpose. So, I separated these library modules from my app code and managed to create equivalent (.aar) files for the respective library modules. Now I created "libs" directory in my "app" and copied all the (.aar) files in to it. Then I written below dependency code in app-level build.gradle file--
implementation(name: 'lib_module_1', ext: 'aar')
implementation(name: 'lib_module_2', ext: 'aar')
implementation(name: 'lib_module_3', ext: 'aar')
implementation(name: 'core_api_lib_module', ext: 'aar')
Also written below code in project-level build.gradle file--
allprojects {
repositories {
jcenter()
google()
flatDir {
dirs 'libs'
}
}
}
Then I Synced the project successfully, but now when I'm trying to run the project, I am getting below run-time error for any random class written in "core_api_lib_module"--
Program type already present: com.core.api.BuildConfig
Sometimes I get same error for any other class written in the same "core_api_lib_module" library. For more details, please find my complete "app/build.gradle" file code as below--

What I tried so far
1] Tried deleting ".gradle" folder from project hierarchy then clean, rebuild and run project but getting same error.
2] Tried deleting all cache from "C:\Users\%USERNAME%.gradle\caches\" directory but getting same error.
3] Tried "Invalidate Caches /Restart" option but still getting same error.
4] Then I googled this "Program type already present" error and tried all the possible option available on below links--
link-1: What does "Program type already present" mean?
link-2: Android Studio - Error:Program type already present
Strange thing I noticed:
I created separate demo app and tried using all 4 (.aar) library files in it, and surprisingly that demo app is working fine without any error. I am able to implement functionality from all 4 (.aar) library file to my demo app but not in actual app.
I hope given information is enough to understand my problem, but still in case you need any other details, please let me know. Thank you!
After 2 days of RND, finally I got the answer. Adding below code in my app-level build.gradle file worked for me--
android {
dexOptions {
preDexLibraries = false
}
}
