dex-method-counts's Issues

publish to central?

can you publish this to central?

Avoid duplication download gradle file

If you have download gradle file in AndroidStudio, then you can replace
"distributionUrl=https://services.gradle.org/distributions/gradle-2.4-bin.zip"
in gradle/wrapper/gradle-wrapper.properties by
"distributionUrl=https://services.gradle.org/distributions/gradle-2.4-all.zip"
then the gradle file would not need to download again.

This tip may be useful to the developers in counties which has limited access to gradle.org

Measure the size of classes/methods?

Hi, I wonder if it is possible to measure the size of methods and classes (LOC bytes, etc)?

Thanks.

can't find dex-method-counts.jar

I git clone this repo to my computer. I enter dex-method-counts/ folder and execute ./dex-method-counts /path/to/my.apk in linux shell and get an error says "can't find dex-method-counts.jar".

What I did wrong? How to solve it and get right output?

Counting in decompiled APK

Can you make it possible to count inside decompiled APK, so I can easly see if i have reached the limit or not when working with smali without having to recompile?

Add Windows instructions

Windows doesn't support the runfile you provided. You can make a .bat file, or provide the different code for Windows:

java -jar [path-to-generated-jar (./build/jar/....)] [filename to inspect]

support of *.aar

Will it be possible to teach tool to work with AAR packages?! This is actually ZIP with JAR inside... so its not exactly the DEX...

but gradle execute special step - preDexLibraries, that actually produce a DEX... so i think its possible to count methods inside AAR in two steps.

Count total number of classes of dex file

Hello, is there any way to count total of classes on dex file,
its on dalvik.system.DexFile package, but must load inside android, if possible to count it outside of android itself

Methods of Android package also included in my JAR for dexcount

Hi i have a JAR which is a library that i have developed for Android devices. I convert the JAR into dex and then run the script. But in my JAR, why are the method counts for android and JAVA packages are involved? These methods are native android and JAVA methods and they don't ship into my JAR. So why are these included for the dex count?

the result is different with android-classyshark

What about release with attached .jar?

What about built .jar? You can create release and attach binary to release directly on the GitHub, mm? https://github.com/blog/1547-release-your-software

Update DEX file magic

https://github.com/mihaip/dex-method-counts/blob/master/src/com/android/dexdeps/DexData.java#L571-L572

static class HeaderItem {
  public static final byte[] DEX_FILE_MAGIC = { 0x64, 0x65, 0x78, 0x0a, 0x30, 0x33 }; // , 0x??, 0x00 };
}

private static boolean verifyMagic(byte[] magic) {
  return Arrays.equals(Arrays.copyOfRange(magic,0,HeaderItem.DEX_FILE_MAGIC.length), HeaderItem.DEX_FILE_MAGIC)
  && magic[HeaderItem.DEX_FILE_MAGIC.length] >= 0x30
  && magic[HeaderItem.DEX_FILE_MAGIC.length+1] == 0x00;
}

does this mechanism support apk's with multidex?

Support "quiet" or "simple" mode

Would be great to have a switch that enables a mode which prints only the total method count. I've added this functionality in my fork but it constitutes some rather reaching changes to the code base that I'm not sure fit the pattern you're currently using.

write to the log

The output information is too long,How to write it to the log?

MultiDex / ART support

It doesn't appear that the script supports builds that result in multiple dex files, where classes are segmented into a primary dex file and additional dex files. The script reports only 22K methods, which I believe to be merely the methods from the primary dex (mostly our own application minus libraries.)

The Android tool chain will generate multiple DEX files when your minSdkLevel is Lollipop / 21 since that is how ART deals with library code (one dex per dependency), and also when you have the multidex switch enabled.

Support for Instant Run APK

Google release Android Studio 2.0 to Stable Channel today, as well as its instant run features. I believe dex-method-counts count the methods incorrectly for APK produced with instant run. If you try to extract the APK, you could see there is a new file instant-run.zip which contains all dexes for each package. I believe this is the reason why dex-method-counts won't work.

Any plan to support this? Thanks.

"Overall method count " does't meet the sum of all packages

$ dex-method-counts --max-depth=1 classes.dex

when I plus each package together, the result is 36290(9104 + 380 + ...+ 29), but the overall method count is 64203. why?

Allow outputting valid yaml

It would be nice if it was possible to easily use the output of this tool for other scripts, that would for example compare binary versions to find regressions.

Yaml seems to be a good candidate as it is already quite similar to the current output. It could be essentially changing the output from

To something like

        codebutler:
            <default>: 65
            android_websockets: 65
        ...

The totals aren't as prominent as in the current format so maybe just make it an option instead of the default format?

Project failed to build, can I still use?

Hi, my project has failed to build due to too many methods, can I use this tool to pinpoint the culprit? I'm not sure how to run it given I don't have an APK file, thanks!

Version number is hardcoded

Version number of dex-method-counts is hardcoded as "1.0" in every versions.
https://github.com/mihaip/dex-method-counts/blob/master/src/info/persistent/dex/Main.java#L203

I'd like to use this useful tool in my daily job and I have to get permission from the security office to do that.
They told me they need managable version number of the object for tracking purpose, so hardcoded one is not acceptable.

how to get methods name

i can get method count,is there anyway to dump methods name?
btw,some classes's method-count are different to javap's.

how to calculate the number of fields in the smali file?

Need to calculate the number of methods and variables in the smali file, not through dex. How?

Cannot use dex-method-counts via a symlink

I created a symlink of dex-method-counts into a directory that was in my $PATH so that I could execute it easily.

However, I found that this does not work; if you execute dex-method-counts via a symlink, it can't find the jar.

I have a fix for this that I've tested on Ubuntu and OS X, and will file a PR shortly.

Export to JSON/XML

Hello, is it possible to add "export data to JSON/XML file" feature?

Recursive

I wanted to count number of classes directly in a application java folder but the library didn't search in sub-folder and stop on the first folder with a java.io.FileNotFoundException (is a directoy) which is true but I'm stuck with that :/

Why not add Classes/Files/LOC count as well?

Why not make this a universal tool for counting all ?
