I recently took over work on an Android Studio project whose active development was stopped 18 months ago, in July 2018.
I have been able to build a debug version of the product, but not release. The build is failing on trying to build a new productFlavor that I added today. This is the build error:
Multiple dex files define Landroid/support/v13/view/inputmethod/InputConnectionCompat$OnCommitContentListener;
After syncing with the gradle in the build.,gradle for module App, new build variants are created. When I select the newFlavorDebug I get the above error. I could go back to the localhost flavor, and could still build localhostDebug, and send it to the emulator to run. However after going through many questions and answers, one of them suggesting a Build -> Clean Project, now I can not get any flavor to build.
Some things I have already tried from other answers:
- I have added to my app build.gradle, within the android{} block:
dexOptions {
preDexLibraries = false
}
- I have added within the android defaultConfig
multiDexEnabled true
Neither of these have helped.
I have found a lot of variations on this question, with the above answers, but they have not helped in my case.
Here is my configuration and dependency blocks from my app build.gradle:
// 2019-11-21 - Added this because of error during build: java.lang.RuntimeException: com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v13/view/DragAndDropPermissionsCompat.class

Note that:
compile 'com.android.support:appcompat-v7:27.1.1'
is getting a warning that some things are asking for version 27.1.1, 26.1.0, and 25.3.1.
I have used this command from Android Studio terminal to see a dependency list:
./gradlew -q :app:dependencies
It seems that https://github.com/polok/RouteDrawer is the source of dependency to 26.1.0, but it is a code base with no updates for the last 5 years:

It is task 5/5 that is failing:

Articles that do not solve the problem I am having:
- Android Studio gradle error: multiple dex files define
- preDexLibraries option added, didn't help
- clean build didn't help (in fact, doing this stopped a flavor from building that used to build before the clean in what I received from previous developers)
