问题描述
而在我们的应用研究记忆问题,事实证明,如果应用程序活动是MapActivity,它的第一个实例不会被最终确定。导致其他内存泄漏等传递到的setContentView的看法。
While investigating memory issues in our application, it turns out that if the application Activity is a MapActivity, the first instance of it won't be finalized. Leading to other memory leak such as the view passed to setContentView.
有没有人注意过吗?
下面是测试code显示出MainActivity:1没有最终确定,而它如果MainActivity自Activity继承
Here is the testing code showing that "MainActivity : 1" is not finalized whereas it is if MainActivity inherits from Activity.
要测试,需要改变设备或模拟器的方向很多次了。
To test, one needs to change device or emulator orientation many times.
import com.google.android.maps.MapActivity;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class MainActivity extends MapActivity {
private static final String defaultTag = "MA";
private static final boolean isDebugModeActivate = true;
private static final boolean isClassTagDisplayed = false;
private static final boolean isWebModeActivate = false;
static public void d(Object thiso, String message)
{
String tag = defaultTag + (isClassTagDisplayed == true ? "_" + thiso.getClass().getSimpleName() : "");
message = (isClassTagDisplayed == false ? thiso.getClass().getSimpleName() + " : " : "") + message;
Log.d(tag, message);
}
public MainActivity()
{
counter++;
uid++;
id = uid;
d(this, id + " tst constructor (" + counter + ")");
}
private static int counter = 0;
private static int uid = 0;
private final int id;
protected void finalize() throws Throwable
{
counter--;
d(this, id + " tst finalize (" +counter + ") ");
super.finalize();
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
protected boolean isRouteDisplayed()
{
return false;
}
}
