What this error means
An Android resource — usually an icon, a splash image or an XML file — is invalid: a bad file name, broken XML, or a reference to something that doesn’t exist.
Why it happens
AAPT2 failed while compiling resources. A bad icon, splash, or XML file, or an illegal resource name, is the usual cause. The first “error:” line names the file.
The message tools print
Execution failed for task ':app:processReleaseResources'.
> Android resource linking failedHow to fix it
- Find the first line starting with “error:” after this one — it names the file.
- Resource file names may only use lowercase letters, digits and underscores.
- Regenerate icons and splash screens if they were edited by hand.
