I learned from the video in Aidl studio, and then I used it to create a note file. The Aidl file created in the video has a set of templates. The Aidl file created in eclipse has nothing, even no code prompt. Error executing Aidl: return code 1.

After traversing various websites, even stackoverflow did not find the answer. There is only one similar eclipse that creates Aidl without generating a java file in the gen directory, and writes a standard Aidl format code according to it. After saving, the error disappears.
