this happens on Android 7 because the version of smali bundled with this project is old.

wrorkaround: both Haystack and Tingle work with Android 7.

@Lanchon: Needle use a version of smali with multi-dex support (not the standard smali) but it is possible that it has some problems.

magic 64 65 78 0a 30 33 37 00 is dex format 037 of android nougat.

it was added to smali on April 1:
JesusFreke/smali@40bbf5c#diff-8cbb11c3776eaef313d2db50d55a286cR52

currently has this form:
https://github.com/JesusFreke/smali/blob/master/dexlib2/src/main/java/org/jf/dexlib2/dexbacked/raw/HeaderItem.java#L46

don't know about mods it may have, but the smali base is old. that's why this error happens.

In fact I have choosen to use the official smali to receive updates earlier, each layer add additional time before updates.
