Adview loadAd（）觸發StrictMode違規

Question

我想在我的應用程序中添加一些添加。當我啓用了StrictMode時，我遇到了一堆像這樣的策略違規（可能是其中的6個或7個）。這是正常的嗎？

爲AD瀏覽的代碼是這樣的：

private void LoadAd(){ 
    Log.d(TAG, "LoadAd() called"); 
    mAdView = new AdView(this); 
    //Finds an ad that best fits a user's device. 
    LinearLayout adContainer = (LinearLayout) findViewById(R.id.adView_container); 
    mAdView.setAdSize(Utils.getBannerSize(this)); 
    mAdView.setAdUnitId(getString(R.string.banner_ad_unit_id)); 
    adContainer.addView(mAdView); 
    AdRequest adRequest = new AdRequest.Builder().build(); 
    mAdView.loadAd(adRequest); 
} 

Answer 1

如果設置StrictMode通過detectAll()或detectDiskReads()檢測DiskReads，當應用程序讀取磁盤時發生StrictMode衝突。

我認爲DiskReads對於正常儲存來說不是問題。因此，您可以禁用以下違規行爲：

StrictMode.ThreadPolicy threadPolicy = new StrictMode.ThreadPolicy.Builder() 
    . ... 
    .permitDiskReads() 
    .permitDiskWrites() // If you also want to ignore DiskWrites, Set this line too. 
    . ... 
    .build(); 

StrictMode.setThreadPolicy(threadPolicy);
