我想在我的应用程序中添加一些添加.当我启用了StrictMode时,我得到了一堆像这样的策略违规(可能是6或7).这是正常的吗？

广告的代码是这样的：
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);
}
最佳答案 如果通过detectAll()或detectDiskReads()将StrictMode设置为检测DiskReads,则当应用程序读取磁盘时会发生StrictMode违规.
我认为DiskReads对于正常情况来说不是问题.因此,您可以禁用以下违规行为：
StrictMode.ThreadPolicy threadPolicy = new StrictMode.ThreadPolicy.Builder()
. ...
.permitDiskReads()
.permitDiskWrites() // If you also want to ignore DiskWrites, Set this line too.
. ...
.build();
StrictMode.setThreadPolicy(threadPolicy);
