Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. > com.android.build.api.transform.TransformException

I'm new at android. I'm trying to add Google sign in feature in my app but when i add com.google.android.gms:play-services-auth:17.0.0 in my build.gradle file,
i'm getting following this error:
Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: androidx/versionedparcelable/CustomVersionedParcelable.class
Kindly suggest solution, i spend whole day but cant get solution.
Build.gradle code is :
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
buildToolsVersion "29.0.1"
defaultConfig {
multiDexEnabled true
applicationId "com.example.mawai.smartlearn"
minSdkVersion 15
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
// compile 'com.android.support:appcompat-v7:26.+'
compile 'com.android.support:appcompat-v7:28.0.0'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
compile 'com.google.android.gms:play-services-auth:17.0.0'
}

In version 17.0.0 and above, you need to use AndroidX, so you have 2 options:
1) Downgrade com.google.android.gms:play-services-auth to older version
2) Add/Migrate AndroidX to your app (Recommended)
Check this link for migration

I am getting the error' compile 'com.android.support:design:23.0.1' compile 'com.android.support:appcompat-v7:23.0.1'

Below is my build.gradle
its giving me the below error if i generate a signed apk

kindly assist on how i can fix this error

Seems like you are including the com.journeyapps:zxing-android-embedded library twice, could be thet you have also saved a jar of it in your lib folder?

Getting error "Execution failed for task ':app:transformClassesWithDexForDebug"

Need help.

The application runs on api level 23 but gives the above error for api 16 which is my minsdk.

Thanks.

First clean project and rebuild,then add following code in your project's app level build.gradle file:
defaultConfig {
multiDexEnabled true
}
In your build.gradle file,
dependencies contains following lines:
compile 'com.google.firebase:firebase-auth:10.2.1'
compile 'com.google.firebase:firebase-database:10.0.1'
compile 'com.google.android.gms:play-services-auth:10.2.1'
Instead this change to following lines:
compile 'com.google.firebase:firebase-auth:10.2.1'
compile 'com.google.firebase:firebase-database:10.2.1'
compile 'com.google.android.gms:play-services-auth:10.2.1'
just make sure each version have same values.

How to solve Execution failed for task ':app:transformClassesWithDexForDebug'?

I am currently developing an android app and implementing in-app purchases.
My application runs fine in simulator mode, but when I try to build an APK I get this following error:
Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Lcom/android/vending/billing/IInAppBillingService;
I'm not sure what is the exact cause, but here are my libraries I am using (IAP library):
Libraries
Lastly, this is my Gradle build which I did set up to compile the library correctly:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "flarehubpe.xflare.flarehub"
minSdkVersion 15
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile 'com.anjlab.android.iab.v3:library:1.0.+'
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.2.0'
testCompile 'junit:junit:4.12'
}
What am I doing wrong?

Try enabling multidex support. Refer the below link to know the steps to enable multidex support in your project.

I solved it by changing an image format from .jpg to .png
