我正在测试一个只有一个Hello world活动的简单Android应用程序：
public class MyActivity extends Activity {
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
long total = Runtime.getRuntime().totalMemory();
long free = Runtime.getRuntime().freeMemory();
Log.d("TEST MEM LEAK ", "max:" + Runtime.getRuntime().maxMemory() / 1024 + "K, total:" + total / 1024 + "K, free:" + free / 1024 + "K");
}
}
这是App第一次打开，我通过以下方式转发了男士信息：
$adb shell dumpsys meminfo com.example.Testmemleak
** MEMINFO in pid 1506 [com.example.Testmemleak] **

这是第二次转储信息：

这是我退出后的日志，并按几次BACK和app图标重新进入应用程序：

似乎堆大小和代理/本地绑定器在退出后继续增加并进入应用程序，为什么？是默认的“内存泄漏”吗？
