Multiple dex files define <my package>/BuildConfig, can't find the cause:
Solution 1
In my case the similar error happened because there were 2 modules with the same package name in AndroidManifest.xml files. Using different package names in the modules solved the problem.
Also the same thing happens when a library jar is being included twice (or more times) in several modules, as a dependency. In this case error message says about duplicate configs named after that library's package name. I solved it with including the library as a dependency in one module, and the second module had in dependencies the first module.
Solution 2
Add this to your build.gradle:
android {
dexOptions {
preDexLibraries = false
}
}
I suppose this way there is no conflicting BuildConfig.java
.
EDIT:
Why the above works:
Android studio will first dex the libraries before dex-ing the app module. If you have a library module with the same package name as your app module, this 'pre-dexing' will result in the creation of a BuildConfig.java
in the same package as for the app.
Note: 'pre-dexing' will slow down your build process a bit so I suggest that you change your library's package name instead.
Solution 3
For me, simply doing a clean on the project cleared this error.
Solution 4
I was getting this problem signing my instant apk. The problem:
bad module/app/manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.stackoverflow">
good: module/app/manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.stackoverflow.app">
Just adding the .app at the end of the package name

I'm using the new gradle build system and I'm facing the following problem:
UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dex.DexException: Multiple dex files define Lcom/kibo/mobi/BuildConfig; at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:594) at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:552) at com.android.dx.merge.DexMerger.mergeClassDefs(DexMerger.java:533) at com.android.dx.merge.DexMerger.mergeDexes(DexMerger.java:170) at com.android.dx.merge.DexMerger.merge(DexMerger.java:188) at com.android.dx.command.dexer.Main.mergeLibraryDexBuffers(Main.java:439) at com.android.dx.command.dexer.Main.runMonoDex(Main.java:287) at com.android.dx.command.dexer.Main.run(Main.java:230) at com.android.dx.command.dexer.Main.main(Main.java:199) at com.android.dx.command.Main.main(Main.java:103)
Priniting the dependencies I can't see anything, here they are:
firstDebugCompile - ## Internal use, do not manually configure ## \--- KiboGradle:KiboSDK:unspecified +--- KiboGradle:TextInputAPI:unspecified +--- KiboGradle:VoiceImeUtils:unspecified +--- com.google.android.gms:play-services:5.0.77 | \--- com.android.support:support-v4:19.1.0 +--- com.squareup.picasso:picasso:2.3.2 +--- com.google.code.gson:gson:2.2.4 \--- com.crittercism:crittercism-android-agent:4.5.1
I tried to verify that the problem is not a duplicate support library so I tried to add:
compile ('com.google.android.gms:play-services:5.0.77'){ exclude module: 'support-v4' }
Which resulted in errors that some of the
support-v4
library classes can't be found, so this library not getting compiled from any other location.One thing I had in mind that could cause this problem is the fact that I using the
Flavors
feautre in oreder to create several versions of my application with different resourse files.And when I look at the file that is in the error I see this:
** * Automatically generated file. DO NOT MODIFY */ package com.kibo.mobi; public final class BuildConfig { public static final boolean DEBUG = Boolean.parseBoolean("true"); public static final String PACKAGE_NAME = "com.kibo.mobi.test.official"; public static final String BUILD_TYPE = "debug"; public static final String FLAVOR = "liverpool"; public static final int VERSION_CODE = 1; public static final String VERSION_NAME = "1.0"; }
So the package in of the file and the package specified in String value are not the same.
Can anyone see any issues in my configuration that could cause this problem?
