Hello friends, Today I tried to add analytics to my game. I am using 2.3.8 2515(Not, 2520 because it is has a huge bug for my game. Start Checkpoint not working after game over) Anyway, I want to add analytics to my game. 1- I tried Firebase today. It gave error. I solved. Another error. I solved. Another error. I could not solve. It gave "Cause: tried to access method com.google.common.io.Files.fileTreeTraverser()Lcom/google/common/collect/TreeTraverser; from class com.android.utils.FileUtils" Lastly. But I could not solve it although I researched this error on the Internet. 2- Then I tried another analytics tool. GameAnalytics. I do not know how is good or bad in iOS but for Android I think it is too old. I downloaded .jar files added them into my Android Studio. I started to make instructions but I realized that they use "compileSdkVersion is set to 23" Then I abondoned instructions because it is too old. Now compile SDK version is 26 fo 2515. Furthermore, it is 28 for 2520. As a result, what is the best analytics tool for Android? Which tool do you use? Flury? Google Analytics? Firebase? GameAnalytics? Which analytics tool do you suggest to me? I would be happy if I had integrated Firebase as it is compatible with Admob. But I am open to new thoughts and ideas. Thanks for any response.
