Error while merging dex archives: com.bumptech.glide.GeneratedRequestManagerFactory

I added native android code to RN app, able to run debug app but while creating release build getting mergeDex error. I am using multidex also still i am getting this issue.
implementation 'com.github.bumptech.glide:glide:4.10.0'
kapt 'com.github.bumptech.glide:compiler:4.10.0'
#GlideModule
class GlideAppModule : AppGlideModule() {
override fun applyOptions(context: Context, builder: GlideBuilder) {
super.applyOptions(context, builder)
builder.apply { RequestOptions().diskCacheStrategy(DiskCacheStrategy.ALL) }
}
}

Any idea how to solve this?

Versions of the platform prior to Android 5.0 (API level 21) use the Dalvik runtime for executing app code. By default, Dalvik limits apps to a single classes.dex
Modify the app-level build.gradle file to enable multidex and add the multidex library as a dependency, as shown here:
android {
defaultConfig {
...
minSdkVersion 15
targetSdkVersion 28
multiDexEnabled true
}
...
}
dependencies {
implementation "androidx.multidex:multidex:2.0.1"
}
create App class
import io.flutter.app.FlutterApplication
import android.content.Context
import androidx.multidex.MultiDex
class App : FlutterApplication() {
override fun attachBaseContext(base: Context) {
super.attachBaseContext(base)
MultiDex.install(this)
}
}
edit your manifest file to set android:name in the tag as follows:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<application
android:name=".App" >
...
</application>
</manifest>
**Note Or You can set the minSdkVersion 21 to avoid this error
refer to the documentation for more info

Set your minimum sdk version to 21.

This means that your app has reached the maximum limit of methods set by android on a single dex file. One way to solve this is to enable multi-dex feature. Follow this link, it provides the best explanation on your issue and how to solve it.

Hopefully some one is able to help me out.

Thanks for your time!

this is a multiDex issue. as you can see here in the stack trace Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html
Add the following in the defaultConfig section of your android/app/build.gradle
multiDexEnabled true
And under the dependencies add the following
compile 'com.android.support:multidex:1.0.3'
This will enable multidex support.

Stack overflow Question
Medium explaining

First of all what you proposed is working!
But is it possible to change the settings in the file android/app/build.gradle
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.flutter_course"
minSdkVersion 16
targetSdkVersion 28
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
multiDexEnabled true
and change the minSdkVersion 16 to 21?
And where can I find the latest version of minSdkVersion, so I can keep it up to date?
Thank you for your help!

D8 DexMergerTransform: flaky android builds on gitlab-ci

Since several days, I see flaky builds on my GitLab CI system.
Sometimes the build fails with this error:
Caused by: com.android.build.api.transform.TransformException: java.lang.IllegalArgumentException
at com.android.build.gradle.internal.transforms.DexMergerTransform.transform(DexMergerTransform.java:230)
When I then retry the build once or twice it works.
I know, this may be difficult to answer, so please add some comments, what I could try or which additional info you would need (unfortunately the project is not open-source): all comments/ideas are welcome.
Here are some thoughts that I have in mind:
maybe this is caused by insufficient memory (it's a quite large multi-module build)
maybe a timing issue of the build
maybe an error in the D8 Dexer
some more info:
the build is not doing any fancy stuff (android UI tests, etc.).
It just executes ./gradlew assembleDebug
com.android.tools.build:gradle 3.0.1
CompileSdkVersion: 26
Here are some relevant parts of the build-log:

AAPT2 failing to merge resources on Docker

I'm trying to build an Android application inside a docker container on a CI server and aapt2 is failing to merge the resources.
Base Docker Image is openjdk:8-alpine
The packages being installed in my image from alpine repositories are:
build-base alpine-sdk bash ca-certificates curl gcc git gzip musl-dev openssh-client python python-dev tar unzip wget
Also I'm downloading and installing Glibc from
https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.25-r0/glibc-2.25-r0.apk
The installed android sdk packages are
build-tools;26.0.0-rc2 platforms;android-25 platform-tools extras;android;m2repository extras;google;m2repository extras;google;google_play_services
The application is currently using Gradle Wrapper 4.0-rc-1
The error is:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:mergeDebugResources'.
> Error: java.lang.ExceptionInInitializerError
* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:mergeDebugResources'.

BUILD FAILED in 30s
I tried installing different alpine packages with no luck.
I have the feeling that this is related to Glibc and/or Musl libraries, but I don't understand it enough not to know how to solve this problem
Also, everything works fine on a very similar image (alpine based too) with build-tools 25.0.3 and Gradle 3.5.
Any clues? Thanks

I stumble upon the same error. The problem as you suspected is that Alpine Linux ships with Musl instead of GNU libc, the Android SDK tooling requires glibc.
You could use something like this: https://github.com/frol/docker-alpine-glibc, or create a similar image on your own if you're comfortable with someone else compiling glibc for you.

You can check which libraries are missing (ENOENT singal) with: $ strace ./aapt2
Then try to create a simbolic link of those libraries to the expected path.
