android ant build无法安装apk但是可以通过IDE工作吗？

Question

I am trying to build a android app via jenkins and ant and the issue is that once it builds with no errors, the app fails to launch after install due to crashlytics.

The exact same app builds and runs perfectly fine using an IDE like Eclipse and all the necesary crashlyitics libs are located in the projects /lib folder.

here is the stack trace of the error when the app is launched.

Answer 1

okay the lib they mention in the logcat:

https://crashlytics.com/register/4346dsd1c0dsadadq77cf/android/com.jr

its probably missing form the libs folder or Jenkins is not picking it up

Answer 2

Hemal from Crashlytics here!

If you run through the Ant setup , you'll be good to go :)

Answer 3

只需在组装前运行./gradlew clean 。
