However, the massive growth of Android malware poses challenging security problems to these terminals and devices. In this paper, we propose a novel heterogeneous information network (HIN)-based method, called FDroid, for fast and accurate detection of Android malware. Specifically, we first design a fine-grained HIN to model the relationship between APKs and APIs and then extract finer-grained path information, including code blocks, packages and call patterns compared to traditional HIN-based methods, which can effectively improve the detection accuracy without increasing the number of paths. Second, we devise a TF-IWF-based contribution calculation algorithm to select a small number of sensitive APIs calls with high representativeness, which can effectively save the detection time and storage space. Third, we develop an expanded matrix-assisted support vector machine (SVM) classifier for Android malware detection. Experimental results show that the FDroid can achieve 97.43% detection accuracy. Meanwhile, compared with the other related HIN-based malware detection methods, the training time of FDroid is less than 0.1% of them, and the detection time is less than 10% of them. <\/jats:p>","DOI":"10.1142\/s0218194025500251","type":"journal-article","created":{"date-parts":[[2025,5,9]],"date-time":"2025-05-09T09:19:14Z","timestamp":1746782354000},"page":"861-886","source":"Crossref","is-referenced-by-count":0,"title":["Identifying Android Malware Using Fine-Grained Path Information from HIN"],"prefix":"10.1142","volume":"35","author":[{"given":"Erfan","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Computer Science and Engineering, University of Electronic Science and Technology of China, Chengdu, P.\u00a0R.\u00a0China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3235-3463","authenticated-orcid":false,"given":"Weina","family":"Niu","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, University of Electronic Science and Technology of China, Chengdu, P.\u00a0R.\u00a0China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5871-946X","authenticated-orcid":false,"given":"Cheng","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Cyber Science and Engineering, Sichuan University, Chengdu, P.\u00a0R.\u00a0China"}]},{"given":"Xixuan","family":"Ren","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, University of Electronic Science and Technology of China, Chengdu, P.\u00a0R.\u00a0China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-7970-9968","authenticated-orcid":false,"given":"Jiacheng","family":"Gong","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, University of Electronic Science and Technology of China, Chengdu, P.\u00a0R.\u00a0China"}]},{"given":"Anran","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, University of Electronic Science and Technology of China, Chengdu, P.\u00a0R.\u00a0China"}]}],"member":"219","published-online":{"date-parts":[[2025,6,19]]},"reference":[{"key":"S0218194025500251BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/SEGE.2019.8859950"},{"key":"S0218194025500251BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/j.iot.2019.100111"},{"key":"S0218194025500251BIB005","doi-asserted-by":"publisher","DOI":"10.1016\/j.cose.2019.101655"},{"key":"S0218194025500251BIB007","doi-asserted-by":"publisher","DOI":"10.1016\/j.cose.2019.101648"},{"key":"S0218194025500251BIB008","doi-asserted-by":"publisher","DOI":"10.1186\/s13673-019-0200-y"},{"issue":"4","key":"S0218194025500251BIB009","first-page":"797","volume":"15","author":"Gafurov K.","year":"2019","journal-title":"J.
