I’m developing a cool project and I came across a difficulty that I couldn’t get out yesterday, the project stopped recognizing all api’s, butterknife, Youtube, everything...

Follow the error:

Noclassdeffounderror: Class not found using the boot class Loader; no stack available

Didn't find class "com.fasterxml.jackson.databind.ObjectMapper" on path: DexPathList[[zip file "/data/app/br.com.dev_sirox.bandmember-2/base.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_dependencies_apk.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_slice_0_apk.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_slice_1_apk.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_slice_2_apk.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_slice_3_apk.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_slice_4_apk.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_slice_5_apk.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_slice_6_apk.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_slice_7_apk.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_slice_8_apk.apk", zip file "/data/app/br.com.dev_sirox.bandmember-2/split_lib_slice_9_apk.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]
java android android-gradle

  • I believe it has to do with Android Manifest, because it had included a class there, I will see more when the night comes home

  • Add the error in the question, don’t let the error depend on external query to the site.

Your error doesn’t show in which line it breaks? One of the answers below can help you solve your problem.

1- Try "Clean" and "Sync Project with Gradle Files". Run your project

2- It may be that your package in manifest.xml and your Mainactivity are different.

3- Disable "Instant Run"

  • It breaks when it calls Firebase and Youtube class, that is, any API

  • I added the bug at the top

  • could post the manifest as well?

  • by what I researched, this type of error happens because of temporary files, or some wrong package declaration in the manifest.

  • try to uninstall the app and install again.

  • old, nothing occurred bug error in my Android Studio, in the company where I work was with the same bug and had updated, solved, old fucking, sinister thing that fucks up out of nowhere! I did this last procedure Disable "Instant Run" and solved!!! But I like this feature!!!

  • I agree with you, it’s a very good resource! but it gives problems.

  • Turns and moves it does not recognize changes made in the project, and apparently causes this error too.

  • Friend, if the answer helped you mark as the correct answer because it can help other people, grateful!

  • I disabled the Instant run and resolved...thanks for the help ^^
