启用 proguard 时未调用 Serializable 中的 readObject 函数
readObject function in Serializable not called when enable proguard
我为 android 应用制作了一个 PersistentCookieStore:
decodeCookie函数:
protected HttpCookie decodeCookie(String cookieString) {
byte[] bytes = hexStringToByteArray(cookieString);
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes);
HttpCookie cookie = null;
try {
MyObjectInputStream objectInputStream = new MyObjectInputStream(byteArrayInputStream);
cookie = ((SerializableHttpCookie) objectInputStream.readObject()).getCookie();
} catch (IOException e) {
Log.d(LOG_TAG, "IOException in decodeCookie", e);
} catch (ClassNotFoundException e) {
Log.d(LOG_TAG, "ClassNotFoundException in decodeCookie", e);
}
return cookie;
}
自定义对象输入流class:
class MyObjectInputStream extends ObjectInputStream {
public MyObjectInputStream(InputStream input) throws StreamCorruptedException, IOException {
super(input);
}
protected ObjectStreamClass readClassDescriptor() throws IOException, ClassNotFoundException {
ObjectStreamClass os = super.readClassDescriptor();
if (os.getName().equals(SerializableHttpCookie.class.getName()))
os = ObjectStreamClass.lookup(SerializableHttpCookie.class);
return os;
}
}
这里是 SerializableHttpCookie class:
public class SerializableHttpCookie implements Serializable {
private static final long serialVersionUID = 6374381323722046732L;
private transient final HttpCookie cookie;
private transient HttpCookie clientCookie;
public SerializableHttpCookie(HttpCookie cookie) {
this.cookie = cookie;
}
public HttpCookie getCookie() {
HttpCookie bestCookie = cookie;
if (clientCookie != null) {
bestCookie = clientCookie;
}
return bestCookie;
}
private void writeObject(ObjectOutputStream out) throws IOException {
out.writeObject(cookie.getName());
out.writeObject(cookie.getValue());
out.writeObject(cookie.getComment());
out.writeObject(cookie.getCommentURL());
out.writeObject(cookie.getDomain());
out.writeLong(cookie.getMaxAge());
out.writeObject(cookie.getPath());
out.writeObject(cookie.getPortlist());
out.writeInt(cookie.getVersion());
out.writeBoolean(cookie.getSecure());
out.writeBoolean(cookie.getDiscard());
}
private void readObject(ObjectInputStream in) throws IOException, ClassNotFoundException {
String name = (String) in.readObject();
String value = (String) in.readObject();
clientCookie = new HttpCookie(name, value);
clientCookie.setComment((String) in.readObject());
clientCookie.setCommentURL((String) in.readObject());
clientCookie.setDomain((String) in.readObject());
clientCookie.setMaxAge(in.readLong());
clientCookie.setPath((String) in.readObject());
clientCookie.setPortlist((String) in.readObject());
clientCookie.setVersion(in.readInt());
clientCookie.setSecure(in.readBoolean());
clientCookie.setDiscard(in.readBoolean());
}
}
当调试一切正常时,readObject
被调用以便 clientCookie
不为空,decodeCookie
return 不为空但是当我启用 proguard 我看到在通话后 readClassDescriptor
readObject
从未通话过。这样 decodeCookie return null.
请帮我修复这个错误。
尝试添加:
-keepnames class * implements java.io.Serializable
-keepclassmembers class * implements java.io.Serializable {
static final long serialVersionUID;
private static final java.io.ObjectStreamField[] serialPersistentFields;
!static !transient <fields>;
private void writeObject(java.io.ObjectOutputStream);
private void readObject(java.io.ObjectInputStream);
java.lang.Object writeReplace();
java.lang.Object readResolve();
}
混淆。
