这个问题怎么产生的

504-02 15:06:45.260 9736 9736 E AndroidRuntime: Caused by: java.lang.VerifyError: Verifier rejected class com.hl.indpark.uis.activities.videoactivities.BaseActivity: io.agora.rtc.RtcEngine com.hl.indpark.uis.activities.videoactivities.BaseActivity.e() failed to verify: io.agora.rtc.RtcEngine com.hl.indpark.uis.activities.videoactivities.BaseActivity.e(): [0x8] returning ‘Reference: io.agora.rtc.RtcEngine’, but expected from declaration ‘Reference: io.agora.rtc.RtcEngine’

java.lang.VerifyError: Verifier rejected 报错可能原因比较多,先看下jar包导入设置又没有问题
