注：如何对内存要求优化非常高的app 可以干掉系统的handler 用Weak Handler 处理

dependencies {    compile 'com.badoo.mobile:android-weak-handler:1.1'}

import com.badoo.mobile.util.WeakHandler;public class ExampleActivity extends Activity {    private WeakHandler mHandler; // We still need at least one hard reference to WeakHandler    protected void onCreate(Bundle savedInstanceState) {        mHandler = new WeakHandler();        ...    }    private void onClick(View view) {        mHandler.postDelayed(new Runnable() {            view.setVisibility(View.INVISIBLE);        }, 5000);    }}
