I am trying to create an Android app to open a PDF file. The goal is to be able to email them and sign them digitally. I'm just looking to open the file by pressing a button.

The application starts but I get the following error:

The application "PdfSigner" has stopped unexpectedly. please try again

activitymain.xml :

    <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:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".PdfActivity" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="168dp"
        android:text="@string/Ouvrir" />

</RelativeLayout>

Activity.java :

    package com.example.pdfsigner;


import ltm.test.R;
import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class PdfActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activitymain);

        //
        Button b1 = (Button)findViewById( R.id.button1 );
        b1.setOnClickListener( new OnClickListener() {

  @Override
  public void onClick(View arg0) {
  String surl = "/ENGLISH.pdf";
  String apptype = "application/pdf";
  if( openURLWithType( surl, apptype ) == false)
          Toast.makeText( PdfActivity.this, 
       "Echec de Open URL", Toast.LENGTH_LONG ).show();
  }});
    }

    public boolean openURLWithType( String url, String type ) { 
        Uri uri = Uri.parse("android.resource://" + getPackageName() + "/R.raw.ENGLISH");

        Intent intent = new Intent( Intent.ACTION_VIEW, uri );
        intent.setDataAndType( uri, type );
        intent.setFlags( Intent.FLAG_ACTIVITY_CLEAR_TOP );
        try {
                PdfActivity.this.startActivity(intent);
                return true;
        } catch (ActivityNotFoundException e) {
                Log.e( "LTM" ,"Activity not found: " + url, e);
        }
        return false;
    }
}

Manifest :

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="ltm.test"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="7"
        android:targetSdkVersion="7" />

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

    <application 
        android:icon="@drawable/ic_launcher" 
        android:label="@string/app_name">
        <activity android:name=".PdfActivity"
                  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>

any help or criticism will be welcome

您似乎忘记修改清单了。你PdfActivity在包里com.example.pdfsigner。

在您的清单标签中，package="ltm.test"应该是package="com.example.pdfsigner"

并提供堆栈跟踪，您在启动应用程序时可能会遇到其他错误。
