意外的意图与行动WEB_SEARCH

Question

我有很大的应用程序来检查很多活动.最受欢迎的例外之一是

找不到活动来处理Intent {act = android.intent.action.WEB_SEARCH(有额外内容)}

有没有搞错？我没有在代码中看到任何"WEB_SEARCH",我无法重现它,我甚至不知道在哪里寻找原因(其中Activity).下面的堆栈Exception,没有我的包中的任何类...如何跟踪和修复此问题？

我必须为另一位未来的搜索者回答我自己的问题.使用在Activity与WebView,或在某些安全Base/ MainActivity抽象层:

@Override
public void startActivityForResult(Intent i, int reqCode, Bundle b){
    boolean activityExists = i.resolveActivityInfo(getPackageManager(), 0) != null;
    if(activityExists)
        super.startActivityForResult(i, reqCode, b);
    else{
        if(Intent.ACTION_WEB_SEARCH.equals(i.getAction()) && i.getExtras()!=null){
            String query = i.getExtras().getString(SearchManager.QUERY, null);
            Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.google.pl/search?q="+query));
            boolean browserExists = i.resolveActivityInfo(getPackageManager(), 0) != null;
            if(browserExists && query!=null){
                startActivity(browserIntent);
                return;
            }
        }
        Toast.makeText(this, R.string.error_no_app_for_intent, Toast.LENGTH_LONG).show();
    }
}

这种行为的原因是(可能)由硬件制作人制作的自定义系统UI/modded Android,它增加了一些与搜索相关的功能.在"干净"的Android设备上无法重现
