Upgrade from Gradle 3.0.0 to 3.4.0 Upgrade from Android SDK 25 to AndroidX

Hi Kanyu, I have update the project by upgrade to the minimal gradle version that could be run by Android Studio 3.2. Hopes you could check it out and merge...

I have just looked into OkReplay, which is cool for normal JSon Response in the body. I wonder if it is possible to work with Google's Protocol Buffer?

Currently gradle sync will fail stating `Cannot set the value of read-only property 'executionData' for task ':app:jacocoTestInternalDebugUnitTestReport' of type org.gradle.testing.jacoco.tasks.JacocoReport.` when upgrade to gradle-6.1.1
