Verifier rejected class com.google.gson.Gson

Hi, I am developing Android app and I faced wired issue recently. My app worked smoothly before, then it broke down few days ago. When I run my app, I got this error. java.lang.VerifyError: Verifier rejected class com.google.gson.Gson due to bad method void com.google.gson.Gson.<clinit>() (declaration of 'com.google.gson.Gson' appears in /data/app/com.xxx.xx-1/base.apk)

I tried many ways, but I still did not fix this error. Could someone help me for this error?

Best Regards.

Hi, I’m getting the same thing in Google’s Pre-Launch report. The strange thing is that I haven’t changed a thing regarding the JSON library from the previous version and that version passed Pre-Launch without any errors

Issue: java.lang.VerifyError: Verifier rejected class com.google.gson.Gson: void com.google.gson.Gson.<clinit>() failed to verify: void com.google.gson.Gson.<clinit>(): [0x5] register v0 has type Precise Reference: com.google.gson.Gson$1 but expected Reference: com.google.gson.reflect.TypeToken (declaration of 'com.google.gson.Gson' appears in /data/app/com.bluegate.app-TXgbYn54WvvOMWt27q0CxQ==/base.apk)

Occurs on Pixel w/Android 8.0 and Pixel 2 w/Android P Preview

For me it was a pre-launch update on Google Publish. Once I opted out for pre-signing, everything passed. Go to the settings under pre-launch reports, go down to “Pre-launch report version”, and select to opt-out so your app doesn’t get recompiled.
