Java 怎么获取 Android APK 版本信息 有没有不使用第三方jar包的方式?

apk是个zip文件,版本号在AndroidManifest.xml里面,但是这个文件是转义过的,需要一些代码进行反转义的

public static void getAndroidManifestInfo(byte[] bytes) {
		try {
			AXmlResourceParser parser = new AXmlResourceParser();
			StringBuilder indent = new StringBuilder(10);
			parser.open(Streams.wrap(bytes));
			while (true) {
				int type = parser.next();
				if (type == 1) {
					return;
				}
				switch (type) {
				case 0:
					log("<?xml version=\"1.0\" encoding=\"utf-8\"?>", new String[0]);
					break;
				case 2:
					log("%s<%s%s", new Object[] { indent, getNamespacePrefix(parser.getPrefix()), parser.getName() });
					indent.append("\t");
					int namespaceCountBefore = parser.getNamespaceCount(parser.getDepth() - 1);
					int namespaceCount = parser.getNamespaceCount(parser.getDepth());
					for (int i = namespaceCountBefore; i != namespaceCount; ++i) {
						log("%sxmlns:%s=\"%s\"", new Object[] { indent, parser.getNamespacePrefix(i), parser.getNamespaceUri(i) });
					}
					for (int i = 0; i != parser.getAttributeCount(); ++i) {
						log("%s%s%s=\"%s\"", new Object[] { indent, getNamespacePrefix(parser.getAttributePrefix(i)), parser.getAttributeName(i), getAttributeValue(parser, i) });
					}
					log("%s>", new Object[] { indent });
					break;
				case 3:
					indent.setLength(indent.length() - "\t".length());
					log("%s</%s%s>", new Object[] { indent, getNamespacePrefix(parser.getPrefix()), parser.getName() });
					break;
				case 4:
				case 1:
					break;
				}
			}
		} catch (Exception e) {
			log.error(e);
		}
	}
private static String log(String format, Object[] arguments) {
		String str = String.format(format, arguments);
		NAME.get().append(str).append("\n");
		return str;
	}

	private static String getNamespacePrefix(String prefix) {

			return "";

AXmlResourceParser 在 AXMLPrinter.jar里面吗?

对 你需要jia包
@sunhai1988

@wendal 我在nutz.cn上传jar文件报错呢

请求报文格式错误。(400:token not specified)

@wendal 方便加个jar到jfrog吗? 我把jar放到群文件了

找源码建个github库呗

是在android.com 上下载的。不用自己维护吧
