android – Adview loadAd()触发StrictMode违规

作者:互联网

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);
}

解决方法:

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);
