Getting "package android.support.multidex does not exist" after upgrading to Android Studio 2.3

Question

I updated from Android Studio 2.2.3 to Android Studio 2.3 yesterday, and I ran into the following two problems:

• Upon updating, Gradle 3.2 was installed by default, but syncing my project would not work and I kept getting an error saying "Gradle 3.3 is required". Using the default Gradle wrapper doesn't work. The only way to fix this was to download Gradle 3.3 manually and point to the directory in build settings.

• On running my project, I kept getting a string of errors involving my BaseApplication class which extends MultiDexApplication. The error goes something like this:

  Error:(19, 62) error: package android.support.multidex does not exist

I am unable to resolve this error. I have buildToolsVersion '25.0.2', and my project compiled and ran properly before upgrading to Android Studio 2.3. Can anyone help me with this problem?

try this answer once,not sure if it will work, just check once – Scutari

just go to settings>build, execution, deployment>gradle> and select "Use default gradle wrapper (recommended)" then rebuild – Seline

@ScottS: I have already tried that but it doesn't work. – Mastoiditis

in your build.gradle do you have multidex enabled and if so have you imported multidex library as part of the dependencies? com.android.support:multidex:x.x.x' in your manifest do you have this line added? package="com.example.android.multidex.myapplication" within manifest tag? post your gradle and your manifest if still need help – Seline

compile 'com.android.support:multidex:1.0.1' try add that to dependencies in build.gradle – Montparnasse

Answer 1

The solution to this problem is to add the following:

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}

in your build.gradle file.

This was not required prior to Gradle 3.3. This problem occurs only for apps that support Android versions below Lollipop (API level 21).

1. Multidex support prior to Android 5.0.

Answer 2

I have passed the building. my solution is that adding explicit dependencies in build.gradle. compile 'com.android.support:multidex:1.0.1'

Replace

with
import androidx.multidex.MultiDexApplication;

Answer 4

I know this is old question but web searching got me here. As of flutter 3.22, (if upgraded from earlier flutter with multidex already enabled) there is a file that needs deleted FlutterMultiDexApplication.java

If App was fine until 3.22 then this is your solution – Fuss

Answer 5

Had this issue after updating to Flutter 3.22. @Paul Charlton's solution worked for me.

Deleting FlutterMultiDexApplication.java found at \android\app\src\main\java\io\flutter\app

Pretty Working Solution(June 2024)

By simply deleting the FlutterMultiDexApplication.java file, I was able to run the app properly. It worked for me. The file is located at android/app/src/main/java/io/flutter/app

Answer 8

In addition to:

dependencies {
    ...
    implementation 'com.android.support:multidex:1.0.3'
}

It is necessary to add this:

defaultConfig {
    ...
    multiDexEnabled true
}
