How to bypass iget-object method return with value

Question

method public getPremium()Ljava/lang/String; .registers 2

.line 1
iget-object v0, p0, Lcom/myapp/android/api/models/User;->premium:Ljava/lang/String;

return-object v0

.end method

Answer 1

The line iget-object v0, p0, Lcom/myapp/android/api/models/User;->premium:Ljava/lang/String; is getting a String into v0.

You can alter the String (and getPremium() return value) this way:

method public getPremium()Ljava/lang/String; 
.registers 2

.line 1
iget-object v0, p0, Lcom/myapp/android/api/models/User;->premium:Ljava/lang/String;

const-string v0, "new value here?"

return-object v0
.end method
