java.lang.VerifyError: ActivityWelcome$AjcClosure1 about let

[embydextrous-zz]

I am getting this error in debug build where let code is in classes2.dex while in release build there is only one dex file so not getting this error.

Thanks @jachenry .

Strange. It seems like a compile time thing. What is the java version you're targeting ? 1.6, 1.7 ?

I'll try to dig into this issue as soon as I can. In the meantime I'll be happy to hear about your progress.

[jachenry]

@canelmas I'm targeting 1.8 in order to use retrolambda plugin. It may only be an issue on emulators. I'll keep you posted on any updates.

I'm having the same problem with APIs prior to 21. Strangely I too am doing some location related stuff after getting the permission.

[embydextrous-zz]

I think this issue happens on multidex build where let code is in secondary .dex file.

@embydextrous My build was not multidex.

Hi guys,
I could circumvent this problem building as release too.
I have java 1.7 as target and the problems exists with Android 4.4 and 4.3 installations over here.

This seems to be because of code swapping added with android gradle plugin 2+. It works fine when building using command line or instant run turned off.
Possibly related to https://code.google.com/p/android/issues/detail?id=204360

[canelmas]

Can you guys please confirm if this is the case as well for you?

@bugraoral

If this is the issue with code swapping. It should not have been observed in release builds.
Code swapping does not work for release builds.

I had the issue with a release build as well. Will test more though.

UPDATE: Tested again with Instant Run disabled and it worked!

[okram2000]

Hey guys,
I cannot reproduce this error with release builds. Only with debug builds!
Furthermore:
Disabling instant run also fixes this error for me!

I have also not observed this error in release builds. I think instant run is the culprit. But I guess when I got this error first time I was using a lower version of android studio and instant run was not present.
Instant run is nightmare a lot of times. Sometimes it swaps my icons and do stupid stuff. I think this is not a library bug.
