Limit Scrolling on offline maps, in Android

Question

I got these piece of codes or patches from osmdroid, and I decided to ask for your help guys because i don\'t have the enough knowledge to combine these codes to come up wit

Answer 1

First of all use this command on your terminal:

svn checkout http://osmdroid.googlecode.com/svn/branches/release_3_0_5

It will download a stable version

Then follow this to import contents of the folder you downloaded:

In Eclipse, right-click on the Package area, and select the following:

click on Import...
select General -> Existing Projects into Workspace
click Next
click Browse...
select the checked out projects' directories
    osmdroid-android (import as a java project)
    OSMMapTilePackager (import as a java project)
    OpenStreetMapViewer (mport as an android project) 
click OK
click Finish

1. Now open this java file--> osmdroid-android/src/org/osmdroid/view/MapView.java
2. Now as stated in this patch file, modify MapView.java ( add code wherever + , remove code wherever -)
3. Also modify computeScroll() in MapView.java as stated here

4. Now, to use this modified .java file, you need to create a new jar file that you can include in your project Here is a step by step process to create jar

5. Add this newly created jar file to your project's build path and you are ready to use your modified jar

6. Now use this in your activity class:

   BoundingBoxE6 bbox  = new BoundingBoxE6(limit north, limit east, limit south, limit west);          
   mapView.setScrollableAreaLimit(bbox);
