Answer 1

i was searching for exactly this error in a few threads and would like anyone who experiences a situation like this to do these steps:

situation:

android studio is throwing errors like @drawable/... not found even renaming files does not solve the problem

solution steps

1. double check the file ( is it present? is the filename valid?)
2. if you can examine an error fix it and run an clean / rebuild of the project
3. if this didnt help take the time and use Android Lint its found at Analyse -> inspect code ... it takes some time but its worth it and now ...
4. fix every error shown, this isnt a joke those errors could prevent you from building the target. do a clean / rebuild

5. now if this still does not work here are the stranges things ive seen:

   • in the filename is an invalid char which doesnt show up in the list or at renaming
   • the file is converted but its empty
   • an file is reverted by git but was deleted in future commits
   • after an code cleanup an xml tag is missing its counterpart

where does these errors come from and why they dont show up in the log

android studio is doing an incremental build , so files are proccessed and used again if they weren't changed. this leads to the following behaviour:

running an build -> collecting files -> proccessing files -> an error occured

all other files in the queue arent found as the couldn't get proccessed by build step the following error is shown as the last error occured aka @drawable not found

Answer 2

Looks like the file res/layout/earn_credits_list_item.xml is trying to reference a drawable that is not present. This resource used to exist in support library < 23.2.0 (and briefly in 23.2.1), but was renamed to abc_ic_ab_back_material in 23.2.0 and in 24.0.0 onward.
If you're using support library > 24.0.0 (which you probably are) rename abc_ic_ab_back_mtrl_am_alpha to abc_ic_ab_back_material.
