Can anyone help or guide me how to do that?


Solution

  • you should implement a chooser, like the example below,

     Intent shareIntent = new Intent();
        shareIntent.setAction(Intent.ACTION_SEND);
        shareIntent.setType("text/plain");//TYPE OF THE CONTENTS,this is for text
        shareIntent.putExtra(Intent.EXTRA_TEXT, noteTitle);//PUT THE EXTRA
     //THIS IS THE LOGIC FOR THE CHOOSER
        Intent chooser = Intent.createChooser(shareIntent,getString(R.string.share_dialog_title));
    
    
        PackageManager manager = getPackageManager();
        List<ResolveInfo> activities = manager.queryIntentActivities(chooser, 0);
        if(activities.size() > 0) {
            startActivity(chooser);
        } else {
            Toast.makeText(NoteListActivity.this, R.string.no_activities_for_action, Toast.LENGTH_LONG).show();
        }
    }
    

    EDIT also check this question, and combine my answer with the answer of this question nad you will get the result Launching an intent for file and MIME type?
