Title mistake
ClassNotFoundException -> ClassCastException

mk...@google.com <mk...@google.com> #3Jan 2, 2023 07:16AM

Reassigned to mk...@google.com.

Thank you for reporting an issue here. Please provide additional information such as R8/AGP version and the original classes of sg.bigo.live.ppi and sg.bigo.live.asd. Ideally a small reproduction or a dump would be very helpful. You can create a dump by adding the following to your build.gradle command:

./gradlew assembleRelease -Dcom.android.tools.r8.dumpinputtofile=mydump.zip --no-daemon

Please share the dump privately with mkroghj@google.com or sgjesse@google.com.

You can read more about compiler dumps here: https://r8.googlesource.com/r8/+/main/doc/compilerdump.md

R8 Version:

classpath("com.android.tools:r8:8.1.5-dev")

I also test with

classpath("com.android.tools:r8:4.0.46")

import com.google.android.gms.internal.p001firebaseauthapi.zzwe;
import java.io.UnsupportedEncodingException;
import java.util.HashMap;

/* loaded from: classes.dex */
public class c7q implements asd, etr {

public /* synthetic */ c7q(Context context) {

}

public /* synthetic */ c7q(Object obj, Object obj2) {

public /* synthetic */ c7q(String str) {

}

....

@Override // sg.bigo.live.asd
public ft2 get(Object obj) {
ft2 ft2Var = ((asd) this.z).get(obj); // ClassCastException !!!!!! this.z was esd
((esd) this.z).p();
} else {
((esd) this.z).c(obj);
}
return ft2Var;
}

....
}

I'll try reproduce this with a small sample.

1. unzip debug.zip
2. execute in terminal

java -jar r8.jar --pg-compat --release program.jar --output out.jar --lib library.jar --classpath classpath.jar --pg-conf proguard.config --pg-map-output out.jar.map --min-api 21

3. open out.jar with jadx
4. search text "TinyDataManager.getInstance" like test.jpg
5. check constructor

Seems like we have a problem with horizontal merging when generating fresh names for variables. I will see if I can make a reproduction and a fix for it.

I will say that I am surprised your app even worked before - there is a bunch of missing classes:

and the entire com.xiaomi library is minified without stack maps making it difficult for R8 to guess the types when there is control flow:

Warning in program.jar:com/xiaomi/push/hn.class at Lcom/xiaomi/push/hn;g()Z:
Expected stack map table for method with non-linear control flow. In later version of R8, the method may be assumed not reachable.
....

I would suggest to fix that such that to be certain that your app will work going forward.

I have removed most of the company's internal code and some code that does not affect the reproduction of bugs.

I’ll try to fix 'Expected stack map table' and test. Thanks!
