java - Import PDF from adobe -

-

i looking following in andriod studio

  1. user open mail client , click preview on pdf. opens file in adobe reader.

  2. the user makes comments in adobe , when done press share

  3. my andriod app shown , users selects app

  4. my andriod app gets pdf , saves externally server.

i have part 1,2,3 far not 4,5. understanding can not access applications storage, poster posted this, unsure on how use that?

in order pdf you'll need create activity use case listens "sharing" intents.

shareactivity.java 

void oncreate (bundle savedinstancestate) {      // intent, action , mime type     intent intent = getintent();     string action = intent.getaction();     string type = intent.gettype();      if (intent.action_send.equals(action) && type != null) {         if ("application/pdf".equals(type)) {             handlepdf(intent);         }      } else if (intent.action_send_multiple.equals(action) && type != null) {         if (type.startswith("application/pdf")) {            // handle multiple pdfs being sent         }     } else {         // handle other intents, such being started home screen     } }   void handlepdf(intent intent) {     uri pdfuri = (uri) intent.getparcelableextra(intent.extra_stream);     if (pdfuri != null) {          // todo: use server-side here save.       } }

and add androidmanifest.xml android knows activity when select application share to:

<activity android:name=".ui.shareactivity" >     <intent-filter>         <action android:name="android.intent.action.send" />         <category android:name="android.intent.category.default" />         <data android:mimetype="application/pdf" />     </intent-filter> </activity>
