您可以查询客户端应用程序（活动）并仅在它是这样的fb / twitter客户端时启动活动：

   final PackageManager pm = getPackageManager();
                    final List<ResolveInfo> matches = pm.queryIntentActivities(shareIntent, 0);
            for (final ResolveInfo info : matches){
                if (info.activityInfo.name.toLowerCase().contains("facebook") || info.activityInfo.name.toLowerCase().contains("twitter")){ 
        Intent sharefacebook = new Intent(Intent.ACTION_SEND); 
                    sharefacebook.setType("image/*");
                    sharefacebook.putExtra(Intent.EXTRA_TEXT, "From Android");              
                    sharefacebook.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+filepath.toString()));                              
                   startActivity(Intent.createChooser(sharefacebook, "Sharing"));   
            }else{
                                Toast.makeText(getApplicationContext(), "FB or twitter client not installed", Toast.LENGTH_SHORT).show();

            }
    }
