Overview

Description

A free and open virtual library, where you will be able to find news, music and of course books, for free. Users can share their opinion of the content with commentaries and give them punctuation that will help the community to find better content. You can also build your personal library, saving all those resources in your account.

App Evaluation

  • Category: Educational / Social networking
  • Story: Create a platform that offers you the resources that you need and show what people think of those resources (rating resource quality and commenting if there was another resource better for them), this can save people a lot of time. As well as saving these resources in the app. And know new resources for different topics.
  • Market: All people on the internet are looking for free music, books and news as well as opinions of these resources.
  • Habit: People are using this constantly throughout their life searching topics of interest for them. Especially if they are students.
  • Mobile: Mobile version is better because it would let users easily access to resources that they saved even without internet connection, as well as be capable of uploading photos for your profile or posts.
  • Scope: V1 would let people search and view by title the resources they want and this will be built over the core of the app (require planning and future goals for next versions). V2 would incorporate the save resource feature. V3 would add comment and rating for every resource as well as a details view. V4 would let users add posts talking about some resources or adding their own ones, as well as asking the community for resources, as well as all the required stories. V5 will implement all the bonus stories.

  • MuPDF

The MuPDF library needs Android version 4.1 or newer. Make sure that the minSdkVersion in your app's build.gradle is at least 16.

android {
 defaultConfig {
   minSdkVersion 16
   ...
 }
 ...
}

The MuPDF library can be retrieved as a pre-built artifact from our Maven repository. Add the maven repository to your project. In your project's top build.gradle, add the bolded line to to the repositories section:

allprojects {
 repositories {
   jcenter()
   maven { url 'http://maven.ghostscript.com' }
   ...
 }
}

Then add the MuPDF viewer library to your app's dependencies. In your app's build.gradle, add the bolded line to the dependencies section:

allprojects {
 repositories {
   jcenter()
   maven { url 'http://maven.ghostscript.com' }
   ...
 }
}

Once this has been done, you have access to the MuPDF viewer activity. You can now open a document viewing activity by launching an intent, passing the URI of the document you wish to view.

import com.artifex.mupdf.viewer.DocumentActivity;

public void startMuPDFActivity(Uri documentUri) {
 Intent intent = new Intent(this, DocumentActivity.class);
 intent.setAction(Intent.ACTION_VIEW);
 intent.setData(documentUri);
 startActivity(intent);
}

The activity supports viewing both file and content scheme URIs.

For example, to open the PDF file in ~/Download/example.pdf:

public void startMuPDFActivityWithExampleFile() {
 File dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
 File file = new File(dir, "example.pdf");
 Uri uri = Uri.fromFile(file);
 startMuPDFActivity(uri);
}
