安卓第三方应用调起常见问题

调用第三方APP

Intent intent = new Intent();
ComponentName cmp = new ComponentName("com.sina.weibo","com.sina.weibo.EditActivity");
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setComponent(cmp);
startActivityForResult(intent, 0);

   另：几个常用的Package命令：

   1.新浪微博(编辑界面)：com.sina.weibo,com.sina.weibo.EditActivity

   2.腾讯微博(编辑界面)：com.tencent.WBlog,com.tencent.WBlog.activity.MicroblogInput

   3.微信：com.tencent.mm,com.tencent.mm.ui.LauncherUI

   4.QQ:com.tencent.mobileqq,com.tencent.mobileqq.activity.HomeActivity

判断是否应用已经安装

//打开微博
private void openWeiBo(Context context, String uid){
  if(isHasWeiBo(context)){
    Intent intent = new Intent(Intent.ACTION_VIEW);
    Uri uri = Uri.parse("sinaweibo://userinfo?uid=" + uid);
    intent.setData(uri);
    Intent chooseIntent = Intent.createChooser(intent, "Weibo");
    startActivity(chooseIntent);
    }
  else{
    Intent intent = new Intent(Intent.ACTION_VIEW);
    Uri uri = Uri.parse("http://weibo.cn/qr/userinfo?uid=" + uid);
    intent.setData(uri);
    Intent chooseIntent = Intent.createChooser(intent, "Weibo");
    startActivity(chooseIntent);
    }
  }

//检查是否有安装微博客户端
private boolean isHasWeiBo(Context context){
  final PackageManager packageManager = context.getPackageManager();// 获取packagemanager
  List<PackageInfo> pinfo = packageManager.getInstalledPackages(0);// 获取所有已安装程序的包信息
  List<String> pName = new ArrayList<String>();// 用于存储所有已安装程序的包名
  // 从pinfo中将包名字逐一取出，压入pName list中
  if (pinfo != null){
    for (int i = 0; i < pinfo.size(); i++){
      String pn = pinfo.get(i).packageName;
      pName.add(pn);
      }
    }
  return pName.contains("com.sina.weibo");// 判断pName中是否有目标程序的包名，有TRUE，没有FALSE
  }
