Facebook Android APP launch other APP wouldn't work (native deep link) -


i have apply facebook app on facebook website, , setup "native android app", include [package name][class name][key hash][facebook login][deep link] ware setup well.

the [package name] , [class name] manifest. 

  <application android:allowbackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/apptheme">     <activity android:name="com.mypackage.myapp.login.login" android:label="@string/app_name" android:screenorientation="portrait" android:launchmode="singletask">       <intent-filter>         <action android:name="android.intent.action.main" />         <category android:name="android.intent.category.launcher" />       </intent-filter>     </activity>   </application> </manifest>

and key hash got following code in app

packageinfo info=getactivity().getpackagemanager().getpackageinfo("com.mypackage.myapp", packagemanager.get_signatures); for(signature signature : info.signatures) {   messagedigest md=messagedigest.getinstance("sha");   md.update(signature.tobytearray());   log.d(constants.tag, "app keyhash: "+base64.encodetostring(md.digest(), base64.default)); }

so i'm pretty sure [package name] , [class name] , [key hash] ware right. , of course, did turned [facebook login] , [deep link] on, in facebook app setup page.

at first, android app using facebook sdk 1.5, deep linking function working well. can click app posted link on "facebook android app", launch "my android app".

but since facebook claimed they'll stop supporting old 2.0 , below sdk, upgraded facebook sdk 3.0 in app, , deep linking not working.

now click app posted link on facebook, facebook android app ask me select 1 of few browser, not launch android app anymore.

what should let facebook deep linking working again, , bring parameter android app when been launched ?

i really need overcome issue, all~
