Files recompiled after apktool decompilation may not run often. If you only modify the language file, you can extract the resources.arsc file with compression software after recompilation to replace the file with the same name in the original software. Be careful not to compress this file (if the file is replaced by WinRAR, the compression method is "storage"), otherwise there may be problems. You can also try to replace the files in the new package with the classes.dex file in the original apk. This can generally run.
