android 解析androidmanifest.xml,如何解析.apk包中的AndroidManifest.xml文件

这个运行在Android上的Java方法记录了.apk包中AndroidManifest.xml文件的二进制格式(我已经能够解释)。第二个代码框显示了如何调用反压缩XML，以及如何从设备上的应用程序包文件加载字节[]。(有些字段的目的我不明白，如果你知道它们的意思，告诉我，我会更新信息。)

// decompressXML -- Parse the 'compressed' binary form of Android XML docs

// such as for AndroidManifest.xml in .apk files

public static int endDocTag = 0x00100101;

public static int startTag =  0x00100102;

public static int endTag =    0x00100103;

public void decompressXML(byte[] xml) {

// Compressed XML file/bytes starts with 24x bytes of data,

// 9 32 bit words in little endian order (LSB first):

//   0th word is 03 00 08 00

//   3rd word SEEMS TO BE:  Offset at then of StringTable

//   4th word is: Number of strings in string table

// WARNING: Sometime I indiscriminently display or refer to word in

//   little endian storage format, or in integer format (ie MSB first).

int numbStrings = LEW(xml, 4*4);

// StringIndexTable starts at offset 24x, an array of 32 bit LE offsets

// of the length/string data in the StringTable.

int sitOff = 0x24;  // Offset of start of StringIndexTable

// StringTable, each string is represented with a 16 bit little endian

// character count, followed by that number of 16 bit (LE) (Unicode) chars.

int stOff = sitOff + numbStrings*4;  // StringTable follows StrIndexTable

// XMLTags, The XML tag tree starts after some unknown content after the

// StringTable.  There is some unknown data after the StringTable, scan

// forward from this point to the flag for the start of an XML start ta
