[Abstract: When I was developing on the AS, I encountered that question, opened all the Java source files, marked with red on the right side, and found no class or method, due to the inability to jump through the face-to-face attack, the development had been entangled for a long time. I tried clean, rebuild, and other methods, but they did not play a role.]

When I encountered this problem during development on AS, I opened all the java source files, marked in red on the right side, could not find the class, and could not find the method, because I could not click to jump, so I had to struggle for a long time during development, I tried clean, rebuild, and other methods, but they didn't work for me. Some colleagues only want to say that it is unnecessary and too troublesome to install the same. After the study, I will refer to the various methods on the Internet, and now I will attach a small skill that I have personally experienced and solved, so as to avoid confusion when encountering such problems, and find the wrong way to solve the problem. (Ps: This method is solved by referring to a problem on the Internet, but the original website cannot be found. So I wrote it here for your reference only)

TIPS:

1. Click File-> Invalidate Caches/Restart...

2. Restart Gradle to clear the cache.

3. After the AS is restarted, java will not be "everywhere"
