3. Search for a MusicListUtils, click Open, and select a method list. You can find a list of downloaded music here, and there are several downloaded music lists. Click on the second one, and you will see the prompt just now. This copyright song does not support downloading for the time being, and the code inside means ifnezv0label 12. It means that if v0 is not equal to 0, it will jump to label 12, which means that it cannot be downloaded, and then ifeqzv0label 1 1, which is the path and method of downloading music, so the modification is simple. If you judge two ifs, you can download music instead. The modification here refers to copying the statements below label 1 1 to above label 12, covering two lines of this copyright song that are temporarily not supported for downloading.

4. Click Compile, then return, click Save, and you will be prompted whether to update classes.dex, and click Update to install the test.
