The Lint feature has been enhanced, causing a lint (warning) on handler

public class WeakRefHandler extends Handler {
private final WeakReference<IHandlerMessage> reference;
public WeakRefHandler(IHandlerMessage t) {
reference = new WeakReference<IHandlerMessage>(t);
public void handleMessage(Message msg) {
IHandlerMessage iHandlerMessage = reference.get();
if (iHandlerMessage != null) {
public interface IHandlerMessage {
void handleMessage(Message msg);

If you make a handler in main thread(UI Thread) then the thread refers to its activity or context.
message in message-queue refers to target handler therefore GC is not working sometimes if the message is stacked in its activity so memory leak will happen
