i think the issue is caused by BmFont

I tested in cocos2dx v3.3rc0
all using BMFont can not work on Android L

I change the cocos2dx v3.3 rc0 Application.mk to cocos2dx v3.2 it works fine
and the httpclient also works fine

I guess the APP_LDFLAGS := -latomic in cocos2dx v3.3 rc0 has a problem

thanks

For BMFont and Httpclient Crash on Android L
I fixed it by use cocos2dx v3.2 Androidk instedof cocos2dx v3.3rc0 Androidk

ex:
Android.MK in cocos2dx v3.3 rc0 (this will crash on Android L)

          APP_STL := c++_static
          NDK_TOOLCHAIN_VERSION=clang 
           APP_CPPFLAGS := -frtti -DCC_ENABLE_CHIPMUNK_INTEGRATION=1 -std=c++11 -fsigned-char
           APP_LDFLAGS := -latomic   this line may caused issue
           ifeq ($(NDK_DEBUG),1)
               APP_CPPFLAGS += -DCOCOS2D_DEBUG=1
               APP_OPTIM := debug
            else
            APP_CPPFLAGS += -DNDEBUG
            APP_OPTIM := release
            endif

Android.MK in cocos2dx v3.2 (this works fine )

         NDK_TOOLCHAIN_VERSION=4.8
         APP_STL := gnustl_static
         APP_CPPFLAGS := -frtti -DCOCOS2D_DEBUG=1 -DCC_ENABLE_CHIPMUNK_INTEGRATION=1 -std=c++11 -fsigned-char
         APP_CPPFLAGS += -fexceptions 

Hey I'm running into this freeze now with v3.3.rc0.
You said it might be -latomic but these lines are also changed (seem pretty drastic):

APP_STL := c++_static
NDK_TOOLCHAIN_VERSION=clang 

I'm working on a massive project that takes a while to recompile, any assistance to narrow it down is greatly appreciated!

I'll see if the sample projects will behave in my env in the meantime.

Some testing with release at HEAD (I forked it and added a couple things but it's pretty much the same):
Using ndk-r9d

• Created new project "LabelTest"
• Left default .mk files
• Text-based .fnt freezes, Binary-based .fnt doesn't (confirming this)

this line also had a problem

NDK_TOOLCHAIN_VERSION=clang
->
NDK_TOOLCHAIN_VERSION=4.8

This issue is cause by 'sscanf' function. The specific reasons is unclear

This issue should be fixed in NDK r10c. For more information : https://code.google.com/p/android/issues/detail?id=77988
