public static int zipMetaInfFolderToApk(String apkName, String folderName) throws IOException {
if(!new File(apkName).exists()){
return ConstantValue.ISQUESTION;
}
String zipName = apkName.substring(0, apkName.lastIndexOf(".")) + "."
+ "zip";
String bak_zipName = apkName.substring(0, apkName.lastIndexOf("."))
+ "_bak." + "zip";
FileUtils.renameFile(apkName, zipName);
ZipFile war = new ZipFile(zipName);
ZipOutputStream append = new ZipOutputStream(new FileOutputStream(
bak_zipName));
Enumeration<? extends ZipEntry> entries = war.entries();
while (entries.hasMoreElements()) {
ZipEntry e = entries.nextElement();
System.out.println("copy: " + e.getName());
append.putNextEntry(e);
if (!e.isDirectory()) {
copy(war.getInputStream(e), append);
}
append.closeEntry();
}
String name = "";
if(folderName.equals("")){
name = "META-INF/" + folderName;
}else{
name = "META-INF/" + folderName + "/";
}
ZipEntry e = new ZipEntry(name);
try{
append.putNextEntry(e);
}catch(ZipException e1){
append.closeEntry();
war.close();
append.close();
FileUtils.renameFile(zipName,apkName);
FileUtils.deleteFolder(bak_zipName);
e1.printStackTrace();
return ConstantValue.ISQUESTION;
}
append.closeEntry();
war.close();
append.close();
FileUtils.deleteFolder(zipName);
FileUtils.renameFile(bak_zipName, apkName);
return ConstantValue.ISNORMAL;
}
