signal 11 (SIGSEGV), code 1 (SEGV_MAPERR) crash spike after updating to 4.3.0

[antonb03]

After updating to 4.3.0 I saw a significant spike in crashes in the native library. I use BlurTransformation in my code and looks like the new version uses RenderScript to accomplish that which I suspect is causing an issue. Here is crashlog that I get.

backtrace:

Hi, I also noticed a significant spike of crash after upgrading this library to 4.3.0. I also use the BlurTransformation inside my app. In fact I guess we are concerned by this part of the CHANGELOG --> - Remove support v8 renderscript (Please use BlurTransformation)

What does Please use BlurTransformation exactly mean ?

[fengluoye2012]

回退到4.2.0版本就可以了 4.3.0使用了RenderScript类进行高斯模糊 会出现上面的崩溃；4.2.0版本使用的是java层的算法实现的高斯模糊 没有问题

[moulie415]

Can confirm I'm on 4.3.0 and seeing the same issue, thank you @fengluoye2012 I will try downgrading to 4.2.0 and see what happens

[hccya1988]

Downgrading to 4.2.0 will use fastbblur for blur bitmap, it is poor performance. Is there a better method to solve this issue?

[DemaHamson]

same issue SIGSEGV(SEGV_MAPERR) in some devices at 4.3.0 , Downgrading to 4.2.0 helped
