java解析APK

解析apk有两种方法
1、结合安卓提供apktool工具,用java执行cmd解析命令获取apk信息
2、利用相关jar包里的集成方法解析apk

这里只给出第二种方法,因为第一种方法在linux服务器下会出现不在控制范围之内的结果。

public class ApkUtil
{
	/**
	 * 日志对象
	 */
	private static Logger	    log	              = LoggerFactory.getLogger(ApkUtil.class);
	
	private static final float	RADIX_MULTS[]	  = { 0.00390625F, 3.051758E-005F, 1.192093E-007F, 4.656613E-010F };
	
	private static final String	DIMENSION_UNITS[]	= { "px", "dip", "sp", "pt", "in", "mm", "", "" };
	
	private static final String	FRACTION_UNITS[]	= { "%", "%p", "", "", "", "", "", "" };
	
	/**
	 * 获取apk信息
	 * 
	 * @param apkPath
	 * @return
	 */
	public static String[] getApkInfo(String apkName)
	{
		// apk信息的返回结果
		final String[] apkResult = new String[3];
		ZipFile zipFile = null;

		{

			// 获得一个解压文件对象
			zipFile = new ZipFile(apkPath);
			// 将解压文件对象转列举对象
			final Enumeration enumeration = zipFile.entries();
			ZipEntry zipEntry = null;
			// 遍历列举对象元素
			while (enumeration.hasMoreElements())
			{
				// 获得一个解压条目对象
				zipEntry = (ZipEntry) enumeration.nextElement();
				if (zipEntry.isDirectory())
				{
					
				}
				else
				{
					// 获得名为AndroidManifest.xml的文件

					}
					
				}
