Didn't find class “android.support.multidex.MultiDexApplication” on path: DexPathList

Question

I\'m trying the new MultiDex Support on my app and so far I\'ve managed to compile my app correctly, but when running it, I get the following exception:

Answer 1

Very strange, I got same error message, but after I fixed some gradle lines it worked. Maybe it helps somebody:

Project build.gradle:

from:

..

dependencies {
        // Android Gradle Plugin
        classpath 'com.android.tools.build:gradle:3.2.1'
        // Analytics
        **classpath 'com.google.gms:google-services:3.0.0'**
}

..

to: ..

dependencies {
        // Android Gradle Plugin
        classpath 'com.android.tools.build:gradle:3.2.1'
        // Analytics
        **classpath 'com.google.gms:google-services:3.2.1'**
}

..

In the module build.gradle:

from:

..

dependencies {
    implementation 'com.android.support:multidex:1.0.3'
    implementation 'com.android.support:support-v4:26.1.0'
    implementation 'com.android.support:support-compat:26.1.0'
    implementation 'com.android.support:appcompat-v7:26.1.0'
    **implementation 'com.google.android.gms:play-services-analytics:12.0.1'**
}

..

to:

..

dependencies {
    implementation 'com.android.support:multidex:1.0.3'
    implementation 'com.android.support:support-v4:26.1.0'
    implementation 'com.android.support:support-compat:26.1.0'
    implementation 'com.android.support:appcompat-v7:26.1.0'
    **implementation 'com.google.android.gms:play-services-analytics:16.0.5'**
}

..

There was no other changes in my code, but the fixed version worked on 4.x emulators too. Only the ** marked lines are changed.

Answer 2

In my case its solved by changes below code in Manifest from

android:name="android.support.multidex.MultiDexApplication"

to

android:name="androidx.multidex.MultiDexApplication"

Answer 3

I was using the latest Android Studio and following the official document to add support to multidex https://developer.android.com/studio/build/multidex.html . But I still got the same exception. I spent a lot of time solving it. At last, I found the cause was I enabled "Java Exception Breakpoints - Any exception", and "Exception Breakpoints - When any is thrown". After I disabled them, the app ran without problems.

Just follow the official document about multidex https://developer.android.com/studio/build/multidex.html . It works.

Answer 4

This worked for me.

File -> Sync Project with Grandle Files

Answer 5

In my case I just changed the build.gradle and I leaved the AndroidManifest like that:

android:name=".MainApplication"

I am using React Native.

Answer 6

For me, the answer was to switch to the androidx versions

android:name="androidx.multidex.MultiDexApplication"

implementation "androidx.multidex:multidex:2.0.1"
