dx for method counting

always prints counts of field and method. (modified version of original dx.jar)

vs. Android Studio APK Analyzer

You can see method references of classes.dex on "Build - Analyze APK" menu in Android Studio.
But if your build fails, there is no APK. You can't use APK analyzer anymore.

If you don't want to use MultiDex and you want to know how many methods are to be removed for build success, dx for method counting will be more helpful.

Usage

1. Backup your original dx.jar (.../Android/sdk/build-tools/[buildToolsVersion]/lib/dx.jar)
2. Replace your dx.jar with this dx.jar(see releases).
3. Disable dexInProcess option.

// file: app/build.gradle
android {
    dexOptions {
        dexInProcess false
    }
