You have to remove the root from the second parameter in File class constructor. When you're instantiating File with File(String dirPath, String name) then the second parameter must contain just the file name and the first the directory where the file is located.
With this correction your code should work :
File pdffile=new File(Environment.getExternalStorageDirectory(),"abc.pdf");

Troubleshooting android displaying error"Unfortunately app has stopped working"

i have created an android app on google maps through eclipse,there are no errors but when i install it on emulator or any android device and run it,error message is displayed that "unfortunately app has stopped working".
please guide me for the troubleshooting.

I think Your Fragment can not cast to MapView. so it could be your classcastexception . if not than you shoud post your logcat output.
try by use this in your Layout may be solve problem:
<com.google.android.gms.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/mainmap"
android:layout_below="#+id/innerrelativelay" />
or
<fragment
android:id="#+id/mainmap"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />

There are a bunch of things missing. Heres a list of what I saw, and some are from comments:
You are extending mapActivity which is based on versio 1 of google maps android. But in xml you are using mapfragment v2 of google maps android.
You should extend FragmentActivity or any other activity like ActionBarActivity that extends from FragmentActivity.
You are missing metadata tag in manifest file.
Min sdk version is 8 so you need to use SupportMapFragment in xml you are using mapfragment which is available above api 11.

Am new to android .i dont know how to display map using fragment.this is my code.i dont get map.my program is unfortunately stopped.and i got error in logcat:No Activity Found to handle.can anyone help me please

You need to activate Google Map API V2 from your google developer console, from there you need to generate map api key, then you need to give that key to map.
Additionally, you need to declare some classes in Android Manifect file, after that you can see map. Its a process and you must need to follow it.
Just visit some good sites like :https://developers.google.com/maps/documentation/android/start

Try this......
<fragment
android:id="#+id/map"
android:class="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Instead of..
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

Here is the complete code to show google maps v2..

Implementing a custom indicator with ViewPageIndicator - How can I do it to a gallery?

I'm working on a project and I managed to get to the point where I can show my images in a gallery sort of style using PagerAdapter. Now what I want to do is add an indicator to which image is on the screen and I figure that VPI could help me out - the problem is that I'm really new to code and don't know how to implement it, could someone help?
Here's a gif of what I want to achieve - the green line indicator: http://imgur.com/GgYgY8I
I made a simpler version of my project to fit in this post, here it is:

public class ImageAdapter extends PagerAdapter {
Context ssContext;
private int[] ssImages = new int[] { R.drawable.splash1,R.drawable.splash2, R.drawable.splash3 };
ImageAdapter(Context ssContext) {
this.ssContext = ssContext;
}
#Override
public int getCount() {
return ssImages.length;
}
#Override
public boolean isViewFromObject(View ssView, Object ssObject) {
return ssView == ((ImageView) ssObject);
}
#Override
public Object instantiateItem(ViewGroup ssContainer, int ssPosition) {
ImageView ssImageView = new ImageView(ssContext);
ssImageView.setScaleType(ImageView.ScaleType.FIT_XY);
ssImageView.setImageResource(ssImages[ssPosition]);
((ViewPager) ssContainer).addView(ssImageView, 0);
return ssImageView;
}
#Override
public void destroyItem(ViewGroup ssContainer, int ssPosition,
Object ssObject) {
((ViewPager) ssContainer).removeView((ImageView) ssObject);
}
}

Thanks in advance to anyone who replies.

Was much more simple than I expected, just needed to add the following to my xml:
<com.viewpagerindicator.UnderlinePageIndicator
android:id="#+id/pageIndic"
android:layout_height="3dp"
android:layout_width="fill_parent"
android:layout_alignParentBottom="true"
app:selectedColor="#ef4154"/>
And the following to the oncreate under the java file:
UnderlinePageIndicator pageIndicator = (UnderlinePageIndicator) findViewById(R.id.pageIndic);
pageIndicator.setViewPager(ssViewPager);

Looking at your error, the problem seems to be
java.lang.UnsupportedOperationException: Unsupported Service: connectivity
Looking at the OSM docs, are you including as a library project or as a jar make sure you have
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
in your AndroidManifest.xml file
