Illegal invoke-super to void com.google.android.gms.common.api.internal.BasePendingResult.setResult(com.google.android.gms.common.api.Result) from class com.google.android.gms.common.api.internal.BaseImplementation$ApiMethodImpl

my project gradle:

Answer 1

You might be getting this issue while creating signed apk file. If yes then this is because of missing proguard rules.

Add rules like below:

verbose
-keep,includedescriptorclasses class com.google.android.gms.internal.** { *; }
-keep class com.google.android.gms.internal.** {com.google.android.gms.internal.** initialize(android.content.Context);}
# -dontnote com.google.android.gms.internal.**
# -dontwarn com.google.android.gms.internal.**
