Today we’ll explain how to install Blackberry themes.This tutorial is
for those who don't know or having troubles in installing applications
on Blackberry. First you will need to know two basic things which will
not be repeated again in this tutorial.
1. How to copy a file to the memory card of a Blackberry?
First
connect the BB* using a data cable to the PC. Then accept 'Enable mass
storage mode' request. Now the memory card will appear in 'My Computer'
as a mass storage device in your PC.
2. How to access the filemanager in my Blackberry?
To
access the filemanager, go to 'Media', then press BB button (left to
the trackball/trackpad). Choose 'Explore'. Now you will see the file
manager. You can access the media/memory card or phone memory from here.
You should be disconnected from PC or disable the mass storage mode in
order to access the media card.
You can install three types of files: .jar, .jad and .cod . Let's look at how to install applications in these formats:
JAR or Java applications:
Blackberry
has limited support for .jar files. It may or may not install on your
BB. Because Blackberry do not support some of the modules required by
some .apps. So these apps won't install or simply gives errors like 'out
of memory'. But there are java apps specifically written for Blackberry
devices. These will install without any hiccup. Here is how to install a
jar file:
1. Copy the jar file to the memory card.
2.
In the BB, open the file manager. Browse to where you saved the jar
file and click it. Now click 'Download'. That's it. It may take a lot of
time unless it is a blackberry specific application.
It
may or may not install because most of the java apps are not designed
for Blackberries especially games. And there are some JAR file which
requires a JAD file to install.
Jad or JAD files:
These
are not application file but just descriptions about apps in other
formats like .jar or .cod which may be hosted on the Internet. You can
edit/open it by simply renaming it to .txt. It usually contains
descriptions like vendor name, file size, time of creation, modules used
etc.
To install it you should have a Data plan (means
if have access to Internet using default web browser in your BB, you can
install it). Just copy it the memory card using mass storage mode and
browse to the JAD file (read about how to do this in previous JAR
method). Click the file and then click 'Download'. The app will be
downloaded and installed within a few minutes.
If you don't have a Data plan, read this:
Rename
the file from .jad to .txt and open it using a text editor. Inside it
you can find the address (near MIDlet-Jar-URL tag) where the JAR file
resides. It will be simply a web URL most of the times but not always.
Copy the URL to a web browser in PC and download the JAR file. Then you
have to edit the JAD file by opening it with a text editor. Just replace
the URL you copied with the name of the app along with extension and
save the file with .jad extension. Then copy both files to a folder in
the memory card. Access the filemanager in the BB and browse to that
folder. Then click the JAD file and click install. It will install that
application.
Cod or COD files:
This is
the native app file format of BB. All apps that have advanced features
will have this format. An application may consist of one or more COD
files. You cannot install a Cod file directly. You will need a
description file to install it. These description files will have
extensions .jad or .alx. Let's see how to handle these files:
1.
To install an app with ALX file you have to use the BB Desktop Manager.
Connect the BB to PC and open the Desktop Manager. Then use the App
Loader in to install the application.
(Select the ALX file inapp loader)
2.
To install an app with JAD description file, copy the whole files to
the memory card. Then access the file manager in your BB to open the JAD
file and click install/download.
So with JAD you can
install an app without using a PC. One more thing to know is that it is
possible to manually write a JAD from ALX or vice-verse. But that is for
only advanced users as it is a bit difficult. I will consider writing a
post about that in future.
That's all you need to know
about installing blackberry application. Hopes this will help a lot of
people who are troubled by insufficient information from RIM regarding
this topic. Please consider tweeting this post as that will help a lot
of people to find this information.
BB stands for Blackberry
