我需要從Manifest.xml中包含的APK中獲取信息，例如名稱（標籤標籤），應用程序圖標的URL等..我發現Ribo發佈了一個非常好的代碼（見下文）。問題是，最後不會將xml文本名稱存儲到APK中，也不會將圖標URL存儲到ResourceID中，而是顯示ResourceID的十六進制代碼，然後如何將此代碼轉換爲文本語言（即String）？ 注：對不起，我的英語關於ribo的代碼來解析從apk到xml的信息
Ribo's'code：
這個Java方法，即在Android上運行，文件（我已經能夠解釋有關）的AndroidManifest的二進制格式。 .apk包中的xml文件。第二個代碼框顯示如何調用decompressXML以及如何從設備上的應用程序包文件加載字節[]。 （有領域，其目的我不明白，如果你知道他們的意思，告訴我，我會及時更新的信息。）

此方法讀取AndroidManifest成一個byte [處理]：
public void getIntents(String path) {
try {
JarFile jf = new JarFile(path);
InputStream is = jf.getInputStream(jf.getEntry("AndroidManifest.xml"));
byte[] xml = new byte[is.available()];
int br = is.read(xml);
//Tree tr = TrunkFactory.newTree();
decompressXML(xml);
//prt("XML\n"+tr.list());
} catch (Exception ex) {
console.log("getIntents, ex: "+ex); ex.printStackTrace();
}
} // end of getIntents
