获取当前目录下所有的apk文件

 public static Vector GetVideoFileName(String fileAbsolutePath) {
        Vector vecFile = new Vector();
        File file = new File(fileAbsolutePath);
        File[] subFile = file.listFiles();

        for (int iFileLength = 0; iFileLength < subFile.length; iFileLength++) {
            // 判断是否为文件夹
            if (!subFile[iFileLength].isDirectory()) {
                String filename = subFile[iFileLength].getName();
                // 判断是否为apk结尾
                if (filename.trim().toLowerCase().endsWith(".apk")) {
                    vecFile.add(filename);
                }
            }
        }
        return vecFile;
    }
