Answer 1

None of the above worked for me, but this developer.android.come guide worked out for me:

https://developer.android.com/studio/build/multidex.html

It says the following:

If your minSdkVersion is set to 21 or higher, all you need to do is set multiDexEnabled to true in your module-level build.gradle file, as enter code hereshown here:

android {
    defaultConfig {
        ...
        minSdkVersion 21 
        targetSdkVersion 25
        multiDexEnabled true
    }
    ...
}

However, if your minSdkVersion is set to 20 or lower, then you must use the multidex support library as follows:

Modify the module-level build.gradle file to enable multidex and add the multidex library as a dependency, as shown here:

android {
    defaultConfig {
        ...
        minSdkVersion 15 
        targetSdkVersion 25
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

Answer 2

for few weeks i was trying to solve this problem.

Now I have found workaround for that. If someone face the same problem, turning off instant Run in Android Studio settings will help.

I know that it is not a solution but it is the best thing for now.

Answer 3

For me adding this line (or commenting out because it is written there in the 13th line) in gradle.properties worked:

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

Also I turned off Instant run (Android Studio 2.1.2).

Answer 4

Refactoring the library helped me resolving this issue. This must have helped in removing duplicate classes from the library or from the app module.

Answer 5

All it took to fix this issue for me was to add the following lines to the build.gradle file for the mobile app:

...

android {

    ...

    // Enabling multidex support.
    multiDexEnabled true
}

dexOptions {
    javaMaxHeapSize "4g"
}

...

}

dependencies {

...

compile 'com.android.support:multidex:1.0.0'

...

}

Answer 6

I discovered many solutions but I solved this issue by adding:

Sol 1: In build.gradle:

defaultConfig {
    multiDexEnabled true
}

Clean your project and rebuild.

Sol 2: If still you have issue in local.properties add,

org.gradle.jvmargs=-XX\:MaxHeapSize\=512m -Xmx512m

Sol 3 Still, You have issue add below mentioned dependency:

compile 'com.android.support:multidex:1.0.1'

Anyone solution will definitely work for you. Otherwise add all 3 in your application.
