检测手机是否有浏览器：
方法一：
public boolean isExitBrowser(Context context,String url){
Uri uri = Uri.parse(url);
Intent intent =new Intent(Intent.ACTION_VIEW,uri);
intent.setComponent(null);
List rList = context.getPackageManager().
queryIntentActivities(intent,PackageManager.MATCH_DEFAULT_ONLY|
PackageManager.GET_RESOLVED_FILTER);
final int browsersize = rList.size();
if(browsersize>0){
// for(int i=0;i
// Log.i(TAG,"i= " + rList.get(i).activityInfo.name);
return true;
}
return false;
}
方法二：
@SuppressLint("WrongConstant")
private boolean hasBrowser(Context context){
PackageManager pm = context.getPackageManager();
Intent intent =new Intent(Intent.ACTION_VIEW);
intent.addCategory(Intent.CATEGORY_BROWSABLE);
intent.setData(Uri.parse("http://"));
List list = pm.queryIntentActivities(intent, PackageManager.GET_INTENT_FILTERS);
final int size = (list ==null) ?0 : list.size();
return size >0;
