Adview loadAd() déclenchant une violation StrictMode

Question

J'essaye d'ajouter quelques ajouts dans mon application. Quand j'ai StrictMode activé, je reçois un tas de violations de politique comme celui-ci (peut-être 6 ou 7 d'entre eux). Est-ce normal?

Le code pour la adview est comme ceci:

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); 
}

Si vous définissez StrictMode pour détecter diskreads par detectAll() ou detectDiskReads(), violation de StrictMode se produit lorsque l'application lit le disque. Je pense que DiskReads n'est pas un problème pour les situlations normales.

Donc, vous pouvez désactiver ces violations comme suit:

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

StrictMode.setThreadPolicy(threadPolicy);
