通过Facebook应用程序而不是浏览器打开Facebook页面的问题

Question

我需要在我已安装的Facebook应用程序中打开Facebook页面。我已要求下面的函数，该函数：

private void loadFacebookUrl() { 
    if (Constant.isOnline(AboutActivity.this)) { 
     try { 
      if (appInstalledOrNot(AboutActivity.this, "com.facebook.katana")) { 
       this.getPackageManager().getPackageInfo("com.facebook.katana", 0); 
       startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/MyPage/")).setPackage("com.facebook.katana")); 
      } else { 
       startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=com.facebook.katana"))); 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } else { 
     Constant.displayToast(AboutActivity.this, getResources().getString(R.string.msg_internet)); 
    } 
} 

但是，我得到我的logcat以下异常：

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=https://www.facebook.com/... pkg=com.facebook.katana }

我应该怎么做才能获得任务做了什么？谢谢。

你的问题是在链接的格式...你应该使用：FB：// facewebmodal/F HREF =

Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://facewebmodal/f?href=https://www.facebook.com/mypage")); 

检查他是否有应用程序，然后使用上面的URL格式，否则将他重定向到浏览器：

String pageurl = "https://www.facebook.com/mypage"; 
boolean hasFacebook = appInstalledOrNot(AboutActivity.this, "com.facebook.katana"); 
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse((hasFacebook?("fb://facewebmodal/f?href="):"") + pageurl)); 
startActivity(i);
