How to open/display documents(.pdf, .doc) without external app?

Question

I want to create a program, that open documents without external app. I need this, because i want to scroll the document with the phones orientation(Pitch and Roll). I create a button on the bottom of the screen, and when i hold down the button, i can scroll the document too. If i release the button, i can't scroll it. So, if i open the document with external app, my button disappears, and the sensorManager works neither.

Have someone any idea to solve this problem. Or have someone any idea, how to scroll the document, opened in an external app, with my phones orientation?

(Sorry for my English)

This is my manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.orientationscrolling"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17" />
<uses-permission android:name="android.permission.INTERNET" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.orientationscrolling.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
</manifest>

This is my Layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<WebView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/webView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="bottom"
    android:orientation="vertical" >

<Button 
   android:id="@+id/mybutt"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:textSize="25sp"
   android:text="Scroll!!"
   android:layout_gravity="right"/>
</LinearLayout>

This is my Code:

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    button = (Button) findViewById( R.id.mybutt );

    String pdf = "http://www.pc-hardware.hu/PDF/konfig.pdf";
    String doc="<iframe src='http://docs.google.com/gview?embedded=true&url=http://www.pc-hardware.hu/PDF/konfig.pdf' width='100%' height='100%' style='border: none;'></iframe>";
    webView = (WebView) findViewById(R.id.webView1);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setPluginsEnabled(true);
    webView.getSettings().setAllowFileAccess(true);
    webView.loadData( doc , "text/html", "UTF-8");
}

Did you find the solution? I am also facing this issue. I couldn't load the docs in webview. — SKK, Dec 19 '14 at 12:33
Same issue the provided solution works well for pdf files but not for .docs or .pptx files. — Ronak Khandelwal, Jun 10 '16 at 06:42

I think you should use custom library for getting that done .See this and this

But there is a way for displaying PDF with out calling another application

This is a way for showing PDF in android app that is embedding the PDF document to android webview using support from http://docs.google.com/viewer

pseudo

String doc="<iframe src='http://docs.google.com/viewer?url=+location to your PDF File+' 
              width='100%' height='100%' 
              style='border: none;'></iframe>";

a sample is is shown below

 String doc="<iframe src='http://docs.google.com/viewer?url=http://www.iasted.org/conferences/formatting/presentations-tips.ppt&embedded=true' 
              width='100%' height='100%' 
              style='border: none;'></iframe>";

Code

    WebView  wv = (WebView)findViewById(R.id.webView); 
    wv.getSettings().setJavaScriptEnabled(true);
    wv.getSettings().setPluginsEnabled(true);
    wv.getSettings().setAllowFileAccess(true);
    wv.loadUrl(doc);
    //wv.loadData( doc, "text/html",  "UTF-8");

and in manifest provide

<uses-permission android:name="android.permission.INTERNET"/>

See this

Caution : I am not aware of compatibility issues with various android versions

In this approach the drawback is you need internet connectivity . But i think it satisfy your need

EDIT Try this as src for iframe

src="http://docs.google.com/gview?embedded=true&url=http://www.pc-hardware.hu/PDF/konfig.pdf"

try wv.loadData( doc , "text/html", "UTF-8"); . Both works for me

It doesn't works for some reason. Here is my phone's display picture: [link](http://uploadpic.org/v.php?img=Lj6SZGXWT4) I add permission to the manifest. This is my Code: 'String doc=""; webView = (WebView) findViewById(R.id.webView1); webView.getSettings().setJavaScriptEnabled(true); webView.getSettings().setPluginsEnabled(true); webView.getSettings().setAllowFileAccess(true); webView.loadUrl(doc);' – KhalDrogo Jan 29 '13 at 09:01
have u given the permission in manifest ..? and in which android version you checked it? – edwin Jan 29 '13 at 09:06
permission: I test it on Android 2.3 – KhalDrogo Jan 29 '13 at 09:17
can you post the link of pdf – edwin Jan 29 '13 at 09:19
please give me the pdf link – edwin Jan 29 '13 at 09:22
String doc=""; – KhalDrogo Jan 29 '13 at 09:23
i try your link it's working perfect for me on android 2.X & 4.X – edwin Jan 29 '13 at 09:30
if i use this, it works, but it not yours solution: String pdf = "http://www.pc-hardware.hu/PDF/konfig.pdf"; webView.loadUrl("http://docs.google.com/gview?embedded=true&url=" + pdf); – KhalDrogo Jan 29 '13 at 10:04
and my main problem is, that i want to scroll my pdf with the phones orientatin(pitch and roll) – KhalDrogo Jan 29 '13 at 10:08
you said it works for you what is the matter then ??if it's work whats the problem?just want to know what went wrong – edwin Jan 29 '13 at 11:27
it doesn't work with your iframe solution, it works with webView.loadUrl("docs.google.com/gview?embedded=true&url="; + pdf url); but it didn't solves my problem, because i cant scroll it with my phones orientation – KhalDrogo Jan 29 '13 at 11:34
i can't see your e-mail adress, but here is mine: buattila4@gmail.com – KhalDrogo Jan 29 '13 at 13:23
How can I save this pdf to phone gallery or email this pdf to a person? – Akanksha Hegde Oct 27 '14 at 06:18
It used to work previously but recently the docs.google.com/viewer?url= doesn't work. It has x-frame-options error and the pdf can't open. – Lee Yi Hong Nov 13 '14 at 03:59

Download the source code from here (Display PDF file inside my android application)

Add this dependency in your Grade:

compile 'com.github.barteksc:android-pdf-viewer:2.0.3'

activity_main.xml

<RelativeLayout android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff"

This library does not provide navigation for links within file. Do you know any other full-proof library with internal link navigation as well? — pratik03, Jul 20 '17 at 11:05

Well, I think below is the solution

 String doc="<iframe src='http://docs.google.com/viewer?url=http://www.example.com/yourfile.pdf&embedded=true' width='100%' height='100%'  style='border: none;'></iframe>";


    WebView  wv = (WebView)findViewById(R.id.wv);
    wv.setVisibility(WebView.VISIBLE);
    wv.getSettings().setJavaScriptEnabled(true);
    wv.getSettings().setAllowFileAccess(true);
    wv.getSettings().setPluginState(WebSettings.PluginState.ON);  
    wv.setWebViewClient(new Callback()); 
    wv.loadData(doc, "text/html", "UTF-8");

Hoping this will help you :)

Above answers that are dependent on google docs will work only when you have internet connection. A better option would be to use Android PdfRenderer class.

You can try sample app here.
