**Description**  
Everything work well in debug. This errror only in release when shrinkResources true and minifyEnabled true in build.gradle with tools:shrinkMode=“strict” in res/raw/keep.xml .  
Remove tools:shrinkMode=“strict” will fix this. But i found that, in res/raw/ in apk file (or aab file) , file ios\_emoji.conf has size = 0 byte. Add “strict” , it will have ~53KB .

**Which Android Client SDK version?**  
v5.5.1.1319

Hi @shpy2001, thanks for the post.

Please try adding the following to your proguard config file:

```auto
-keep class us.zoom.**{*;}
-keep class com.zipow.**{*;}
-keep class us.zipow.**{*;}
-keep class org.webrtc.**{*;}
-keep class us.google.protobuf.**{*;}
-keep class com.google.crypto.tink.**{*;}
-keep class androidx.security.crypto.**{*;}

```

Hi @jon.zoom , i already add those rule to proguard. The problem is at tools:shrinkMode=“strict” in res/raw/keep.xml.
