Android的Admob的间质内存泄漏 [英] Android Admob Interstitial Memory leak

问题描述

我想在一些活动结束，显示间隙。问题是间隙似乎prevent活动被垃圾收集，造成内存不足的例外。请问该如何解决呢？先谢谢了。

 公共类AdActivity扩展FragmentActivity {

// ...

保护InterstitialAd间质性;

@覆盖
保护无效的onCreate（包savedInstanceState）{
    super.onCreate（savedInstanceState）;

    // ...

    //创建间隙。
    间质性=新InterstitialAd（本）;
    interstitial.setAdUnitId（INTERSTITIAL_UNIT_ID）;

    //创建广告请求。
    AdRequest adRequest2 =新AdRequest.Builder（）。addTestDevice（AdRequest.DEVICE_ID_EMULATOR）
            .addTestDevice（DEVICEID）
            。建立（）;

    //开始装货间隙。
    interstitial.loadAd（adRequest2）;
}

@覆盖
公共无效的onPause（）{
    super.onPause（）;
    displayInterstitial（）;
}


公共无效displayInterstitial（）{
    如果（interstitial.isLoaded（）＆安培;＆安培; System.currentTimeMillis的（）＆GT; = lastInterstitial +时间滞后* 1000）{
        lastInterstitial = System.currentTimeMillis的（）;
        interstitial.show（）;
    }
}
 

和我用它喜欢的：

 公共类ActivityA扩展AdActivity {// ...
}
 

解决方案

好吧，我似乎被改变有固定

 间质性=新InterstitialAd（本）;
 

到

 间质性=新InterstitialAd（getApplicationContext（））;
 

我不完全理解在Java / Android的内存管理，但我想，怎么回事是因为活动的参考间质和质的引用，这样的活动既没有得到垃圾收集。传递中的应用程序上下文，而不是活动范围内prevents这个循环依赖和解决的问题。希望这可以帮助别人。：D

I'm trying to show interstitials at the end of some Activities. The problem is the interstitials seem to prevent the Activities from being garbage collected causing an out-of-memory exception. How do i resolve this? Thanks in advance.

public class AdActivity extends FragmentActivity{

//...

protected InterstitialAd interstitial;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //...

    // Create the interstitial.
    interstitial = new InterstitialAd(this);
    interstitial.setAdUnitId(INTERSTITIAL_UNIT_ID);

    // Create ad request.
    AdRequest adRequest2 = new AdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
            .addTestDevice(deviceId)
            .build();

    // Begin loading interstitial.
    interstitial.loadAd(adRequest2);
}

@Override
public void onPause() {
    super.onPause();
    displayInterstitial();
}


public void displayInterstitial() {
    if (interstitial.isLoaded() && System.currentTimeMillis() >= lastInterstitial + timeLag * 1000) {
        lastInterstitial = System.currentTimeMillis();
        interstitial.show();
    }
}

And i used it like:

public class ActivityA extends AdActivity{ //...
} 

解决方案

Ok i seem to have fixed it by changing

interstitial = new InterstitialAd(this);

to

interstitial = new InterstitialAd(getApplicationContext());

I don't completely understand memory management in java/android but I think whats going on is because the Activity references interstitial and interstitial has a reference to Activity so neither gets garbage-collected. Passing in the application context rather than the Activity context prevents this cycle dependency and solves the problems. Hope this helps someone :D.
