Force close app when build release apk with enableSeparateBuildPerCPUArchitecture and enableProguardInReleaseBuilds = true

[gandarain]

I try to implement chat feature with voximplant in. my React Native app and I use react native voximplant sdk, for my project. In debug mode, everything is fine. In release mode with set enableSeparateBuildPerCPUArchitecture and enableProguardInReleaseBuilds equal to false, everything is working fine too. But when I try to set enableSeparateBuildPerCPUArchitecture and enableProguardInReleaseBuilds equal to true. My react native app will force close. I try to figure out, what happend and what fuction will make a force close app. And I found this

async loginVoximplant() {
    let clientConfig = {}
    let client = Voximplant.getInstance(clientConfig)
    try {
      await client.disconnect()
      let state = await client.getClientState()
      if (state === Voximplant.ClientState.DISCONNECTED) {
        await client.connect()
      }
      let authResult = await client.login(this.props.profile.voximplant_username, this.props.profile.voximplant_password)
      console.log('Response from login voximplant ', authResult)
      this.getTransactionChat(this.props.profile.type)
    } catch (e) {
      console.log('Error from login voximplant ', e)
    }
  }

I call this function in my component did mount, when I command this function, everything working fine with enableSeparateBuildPerCPUArchitecture and enableProguardInReleaseBuilds equal to true. I dont know why. Please give me an solution for this problem

Hello @gandarain ,

I think the issue might be cause by enableProguardInReleaseBuilds = true and proguard strips some parts of the Voximplant native SDK.

Please add to the proguard rules the following:

-keep class org.webrtc.voiceengine.** {*;}
-keep class org.webrtc.** {*;}
-keepnames public class org.webrtc.voiceengine.** {*;}
-keepnames public class org.webrtc.** {*;}
-keepclasseswithmembernames class * { native <methods>; }

-keepclassmembers enum * {
    public static **[] values();    public static ** valueOf(java.lang.String);}

-keep public class com.zingaya.voximplant.* {
      public protected *;}

-keep public class com.voximplant.sdk.* {
      public protected *;}

and the rules from our dependencies: https://github.com/google/gson/blob/master/examples/android-proguard-example/proguard.cfg https://github.com/square/okhttp/blob/master/okhttp/src/main/resources/META-INF/proguard/okhttp3.pro

Please let me know the results.

Best regards, Yulia Grigorieva

Thanks for your answer, I have seen the link you sent. But I dont know where I will put the command from this link. https://github.com/google/gson/blob/master/examples/android-proguard-example/proguard.cfg https://github.com/square/okhttp/blob/master/okhttp/src/main/resources/META-INF/proguard/okhttp3.pro

Any idea, where I should put that command? Thanks.

[YuliaGrigorieva]

You should have proguard-rules.pro file in your project located in <your_project>/android/app folder.

You need to put everything from these files and a snippet that I have provided in my previous comment to this file.

Your solution is working, my application will not force close again, but now I get a new error from get conversation. When debug mode, everything is working fine, you can see this image.

But when relase mode and enableSeparateBuildPerCPUArchitecture and enableProguardInReleaseBuilds equal to true, I get an error in get conversation. This is my code, for get conversation,

async getConversation(conversation_id) {
    try {
      let messaging = Voximplant.Messaging.Messenger.getInstance()
      let conversation = await messaging.getConversation(conversation_id)
      this.setState({ conversation })
      console.log('Response from get conversation voximplant ', conversation)
    } catch (e) {
      console.log('Error from get conversation voximplant ', e)
      Alert.alert('Error', `Error get conversation voximplant ${JSON.stringify(e)}`)
    }
  }

The error code is 10002, description error is Response Timeout.

Any idea, how to fix this error?

Hi @gandarain !

Is it 100% reproducible issue?

I need the SDK logs with getConversation response to understand what causes this issue.

[gandarain]

Hi, thanks for reply this issue. DId you mean this log?

[YuliaGrigorieva]

No, I mean adb logcat logs (from Android Studio for example) with VOXSDK tag

Did you mean this log?

Hello @gandarain ,

Sorry for the delayed response.

Yes, I need these logs. However, could you please capture them starting a messaging API call, i.e. "getConversation" or any other you received an error.
