BlurView is not working in signed-release apk

[madiguzel]

Hi,

Thanks for this useful component. It works in debug mode as expected but i cannot get the blurview work in signed release apk. Is there any configuration for release mode? Any proguard rules?

SIGNED RELEASE APK

DEBUG APK

Thanks in advance...

No proguard rule needed. Does it crash or it just not working. Can you check logcat.

Hi again,

It doesn't crash but I see lots of error logs in logcat like:

Hi again,

I founded the solution. It works perfectly now.

When minifyEnabled is true in gradle file, we need to add the following proguard rule:

-keep class android.support.v8.renderscript.** { *; }

After migration to androidx library can also help you:

-keep class androidx.renderscript.** { *; }
