Whenever i build the app in Android Studio, the files will be re-downloaded again. I have even tried to delete cache file.
Any Solution?

I think this is caused by the alpha version of constraintlayout.
//Constraint Layout
implementation("androidx.constraintlayout:constraintlayout-compose:1.1.0-alpha06")
I had the same issue, when I downgraded the constraintlayout-compose version to 1.0.1 everything worked again.

Execution failed for task ':app:checkReleaseDuplicateClasses'

I have a build issue suddenly in my react-native android build. The surprise is it was built in the morning fine, didn't make any changes but, suddenly, it's failing. here's what I get as the error. any idea why this happens? Did saw some similar issues in stack and GitHub also, but any fixes suggested in those didn't work for me so far. seems those stack-traces are somewhat different to mine.
* What went wrong:
Execution failed for task ':app:checkReleaseDuplicateClasses'.

This is due to a dependency update. Some lib you're using had a loose dependency specified and installs kotlin 1.8.0 dependencies. It was the case for me here.
You can fix it by adding kotlinVersion in your build.gradle config:
buildscript {
ext {
buildToolsVersion = "32.0.0"
minSdkVersion = 21
compileSdkVersion = 33
targetSdkVersion = 32
androidXBrowser = "1.4.0"
kotlinVersion = "1.8.0"
}
...
}

There 2 things to check and update.
1. Update kotlinVersion
buildscript {
ext {
kotlinVersion = "1.8.0"
}
}
2. Update org.jetbrains.kotlin.android
If org.jetbrains.kotlin.android is still 1.7.* then it does not works.
plugins {
id 'org.jetbrains.kotlin.android' version '1.8.0' apply false
}

I can't believe this, but upgrading Material 3 from version 1.1.0-alpha04 to version 1.1.0-alpha05 caused the issue in my case:
// Material 3 Lib - this version is causing the problem
implementation("androidx.compose.material3:material3:1.1.0-alpha05")
Just downgrade to alpha04 for now.
// downgrade to this version
implementation("androidx.compose.material3:material3:1.1.0-alpha04")
I am using Kotlin DSL and I found upgrading Kotlin version from 1.7.20 to 1.8.0 doesn't solve the issue. Kotlin Version 1.8.0 is not compatible with kotlinCompilerExtensionVersion = "1.3.2"

Was to able to solve by adding android.enableJetifier=true in gradle.properties file

What is Duplicate class found in modules classes.jar error in Android Studio (when trying to connect to Firebase) and how to solve it?

I am trying to use Firebase database in my Android App ut I'm dealing with some errors:
I got this error first:
Manifest merger failed : Attribute application#appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:6:5-24:19 to override.
I searched a way to fix it and found that migrating to AndroidX would be a good thing to do. But after I migrated to AndroidX (Refactor -> Migrate to AndroidX) I got this error:

I think it is a dependency error because implementation 'com.android.support:appcompat-v7:28.0.0'is underlined in red.. but I don't know how to fix it.. Can anyone please help me?
