Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat

Question

If I run gradle assembleDebug from the command line, I am suddenly getting this error:

UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dx.util.DexEx

I had the same problem when adding react-native-palette to my project, here is my dependencies tree:

./gradlew app:dependencies
+--- project :react-native-palette
|    +--- com.facebook.react:react-native:0.20.+ -> 0.44.2
|    |    +--- javax.inject:javax.inject:1
|    |    +--- com.android.support:appcompat-v7:23.0.1
|    |    |    \--- com.android.support:support-v4:23.0.1
|    |    |         \--- com.android.support:support-annotations:23.0.1 -> 24.2.1
...
|    \--- com.android.support:palette-v7:24.+ -> 24.2.1
|         +--- com.android.support:support-compat:24.2.1
|         |    \--- com.android.support:support-annotations:24.2.1
|         \--- com.android.support:support-core-utils:24.2.1
|              \--- com.android.support:support-compat:24.2.1 (*)
+--- com.android.support:appcompat-v7:23.0.1 (*)
\--- com.facebook.react:react-native:+ -> 0.44.2 (*)

I tried many solutons and could not fix it, until changing the com.android.support:appcompat version in android/app/build.gradle, I wish this can help:

dependencies {
    compile project(':react-native-palette')
    compile project(':react-native-image-picker')
    compile project(':react-native-camera')
    compile fileTree(dir: "libs", include: ["*.jar"])
    // compile "com.android.support:appcompat-v7:23.0.1"
    compile "com.android.support:appcompat-v7:24.2.1"
    compile "com.facebook.react:react-native:+"
}

it seems that multiple entries is not a big problem, version mismatch is
