Mapsforge 0.9.0: Android dex error (mapsforge-map-android-extras)

[dominicschaff]

I have been using maps forge 0.8.0 with great success but when updating to 0.9.0 I am unable to compile the project anymore. I am unsure what I have done wrong.

I am compiling for SDK 26 with build tools 26.0.2, using Android Studio 3
My minimum SDK is version 16 and target is 25

The dependancies I have for the maps are:

dependencies {
    compile 'org.mapsforge:mapsforge-map-android:0.8.0'
    compile 'com.caverock:androidsvg:1.2.2-beta-1'
    compile 'org.mapsforge:mapsforge-themes:0.8.0'
    compile('org.mapsforge:mapsforge-map-android-extras:0.8.0') {
        transitive = false
    }
}

Other dependancies are:

dependencies {
    compile 'com.android.support:appcompat-v7:26.1.0'
    compile 'com.android.support:cardview-v7:26.1.0'
    compile 'com.android.support:design:26.1.0'
    compile 'com.android.support:support-v4:26.1.0'
    compile 'com.amazonaws:aws-android-sdk-core:2.6.9'
    compile 'com.amazonaws:aws-android-sdk-cognito:2.6.9'
    compile 'com.amazonaws:aws-android-sdk-sqs:2.6.9'
    compile 'com.amazonaws:aws-android-sdk-s3:2.6.9'
    compile 'com.joshdholtz.sentry:sentry-android:1.6.2'
    compile 'com.koushikdutta.ion:ion:2.2.1'
    compile 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.2.0'
    compile 'com.journeyapps:zxing-android-embedded:3.5.0'
}

But as soon as I update to 0.9.0 (and try run on a device) I get a compile error:

Error:

Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDevelopmentDebug'.
> java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

I can just confirm that this error happens when changing from 0.8.0 to 0.9.0 and no other change in the project. Not sure what causes this.

I have noticed that even if I use less of the maps dependancies and only use the themes and android-extras I still get the same error (and the transitive bit doesn't seem to make much difference).

Try to update the build-tools. I had a similar problem with another library. Just a try …

[devemux86]

Has been noted that new Android Studio 3 / Gradle 4 / Android plugin 3 behave a bit strange in dependencies, regarding run configurations.

Please use the latest Android build tools like officially recommended and avoid deprecated calls, e.g. compile -> implementation.

For example in apps with many dependencies, like the GraphHopper Android sample which I maintain and uses also Mapsforge/VTM libraries.
We enabled the minifyEnabled in its build type (see here) with generic proguard rules to compile and run fine.

[dominicschaff]

I will try the recommendations and comment here what the result is

[dominicschaff]

I updated the build tools version to 27.0.2 (which is the latest according to the SDK tools)
And updated the dependancies to:

dependencies {
    implementation 'org.mapsforge:mapsforge-map-android:0.9.0'
    implementation 'org.mapsforge:mapsforge-themes:0.9.0'
    implementation('org.mapsforge:mapsforge-map-android-extras:0.9.0')
}

I then cleaned my build, but I am getting the same issue. And as soon as I change back to 0.8.0 issue goes away.

So I have managed to get the issue down to just maps forge libraries.

Also I cannot enable the minify, as soon as I do that the app does not compile, but that is related to some other libraries I am using.

[devemux86]

Can you try with all Mapsforge required dependencies, as mentioned in integration guide?

BTW internet and Stack Overflow are full of questions for latest Android Studio and "Unable to merge dex" issues. Some recommend multiDexEnabled, other minifyEnabled and other to check for duplicated dependencies (via transitive).

[dominicschaff]

I now have it working again. Thanks @devemux86

I added all the dependancies from "Core" and "Android"

Now it is working again.

[dominicschaff]

So I am assuming one of the dependancies may have moved or something. But it is working so I am happy. Thanks for the quick responses

[devemux86]

• I created a new simple project with the Getting started guide and all latest Android tools.
• It compiles / runs fine using the Mapsforge core + Android libs as mentioned in integration guide.
• If add also the mapsforge-map-android-extras then the troubles start.

That module doesn't even belong in Mapsforge, since handling permissions is clearly app's (not library's) responsibility and can be done with too many more intuitive ways.

[dominicschaff]

I removed the extras package, as it seems I had stopped using it at some point. Also I am not sure what I was using it for either.

[devemux86]

I contains code for handling (some) runtime permissions, since Android 6.0 (API 23).

[dominicschaff]

I handle the permissions elsewhere, as I use them in the app. Which is probably why I stopped using them
