Question

我已经在Android文档中阅读了有关“非SDK接口的限制”的内容：

只要应用引用非SDK，就会应用这些限制接口或尝试使用反射或JNI获取其句柄... 非SDK接口的处理是一个实现细节， API抽象了；它可随时更改，恕不另行通知... 列入灰色名单的非SDK接口包含方法和字段继续在Android 9中运行，但我们不能保证在平台的未来版本中访问...您可以使用adb logcat来访问这些日志消息，这些消息显示在正在运行的PID下应用...

以下是在API 28仿真器上运行的代码的相关部分：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState); 

           ................       

    MobileAds.initialize(this,  "ca-app-pub-3940256099942544~3347511713");

           ................

    adView = new AdView(this);

    adView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");
    adView.setAdSize(AdSize.BANNER);
    adView.setBackgroundColor(Color.TRANSPARENT);
    adView.setVisibility(View.GONE);            
    adView.loadAd(adBuilder());

           ................

    interstitial = new InterstitialAd(GLGame.this);            
    interstitial.setAdUnitId("ca-app-pub-3940256099942544/1033173712");
    interstitial.loadAd(adBuilder());        

    mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
    mRewardedVideoAd.setRewardedVideoAdListener(this);        
    loadRewardedVideoAd();        
}

AdRequest adBuilder() {
    return new AdRequest.Builder().build();
}
public void loadRewardedVideoAd() {        
    mRewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917", new AdRequest.Builder().build());        
}

我发现与

MobileAds.initialize(this,  "ca-app-pub-3940256099942544~3347511713");
adView.loadAd(adBuilder());
interstitial.loadAd(adBuilder());

我的Logcat输出是：

W: Accessing hidden method Landroid/view/textclassifier/logging/SmartSelectionEventTracker;-><init>(Landroid/content/Context;I)V (light greylist, reflection)
W: Accessing hidden method Landroid/view/textclassifier/logging/SmartSelectionEventTracker;->logEvent(Landroid/view/textclassifier/logging/SmartSelectionEventTracker$SelectionEvent;)V (light greylist, reflection)

如果我通过评论禁用

//MobileAds.initialize(this,  "ca-app-pub-3940256099942544~3347511713");
//adView.loadAd(adBuilder());
//interstitial.loadAd(adBuilder());

正在访问的隐藏日志猫消失了。

与我获得Logcat输出之前相同：

W: Accessing hidden method Landroid/media/AudioTrack;->getLatency()I (light greylist, reflection)

如果我通过评论禁用

//loadRewardedVideoAd();

正在访问的隐藏日志猫消失了。

如您所见，代码：

MobileAds.initialize(this,  "ca-app-pub-3940256099942544~3347511713");
adView.loadAd(adBuilder());
interstitial.loadAd(adBuilder());
loadRewardedVideoAd();

导致了很多访问隐藏的logcat。

我的问题是：

这些是模拟器的问题吗？
我是否有可能使用NON-SDK接口（请参阅访问隐藏方法，浅灰色列表，反射）会在平台的未来版本中破坏我的应用程序吗？
如何解决？

列入灰色名单的非SDK接口表示方法和字段在Android 9中继续起作用，但是Google不保证在以后的平台版本中可访问这些方法和字段。如果由于某种原因您无法实施灰名单API的替代策略，则可以提交错误以请求重新考虑该限制。
