“分享”意图后,Android应用程序崩溃

概述我的应用程序提供了“分享/告诉朋友”功能.当按下“共享”按钮时,将调用以下方法来打开应用程序列表,这些应用程序可以执行 *** 作(例如Gmail,Twittroid,Facebook…)：publicvoidshare(){IntentshareIntent=newIntent(android.content.Intent.ACTION_SEND);shareInt

我的应用程序提供了“分享/告诉朋友”功能.当按下“共享”按钮时,将调用以下方法来打开应用程序列表,这些应用程序可以执行 *** 作(例如Gmail,TwittroID,Facebook …)：

public voID share() {    Intent shareIntent = new Intent(androID.content.Intent.ACTION_SEND);    shareIntent.setType("text/plain");    shareIntent.putExtra(androID.content.Intent.EXTRA_SUBJECT, getText(R.string.menu_share_subject));    shareIntent.putExtra(androID.content.Intent.EXTRA_TEXT, getText(R.string.menu_share_body));    startActivity(Intent.createChooser(shareIntent, getText(R.string.menu_share_intent)));      }

共享功能基本上可以正常工作.但是,当共享应用程序(Facebook,Twitter等)尝试返回到我的应用程序时,将强制关闭.

我想我的应用在共享过程中会在后台关闭.至少这就是调试器所说的.

有任何想法吗？

问题似乎是该应用程序在后台关闭.另外,当我从应用程序打开浏览器时,请尝试使用返回键返回到我的应用程序.强制关闭.这是Log Cat的输出
