Android : Calling the other package activity from the current package Activity

Hi All,

After a long time one more android blog, or you can say a new problem which I encounter. In general cases we call activity using intent within the same package. but what if we want to call some other package activity. So here is the solution. Here I will be using the name convention as Calling Activity as First Activity and Called Activity as Final Activity.

Method 1 : Using setClass() method in Intent class.

It is the same thing which you do in normal scenario but with a little tweak in it. In FirstActivity where ever you want to call other activity from other package, put following code

Intent i = new Intent();
i.setClassName("com.android.finalactivity", "com.android.finalactivity.FinalActivity");
startActivity(i);

/* Here com.android.finalactivity is the package name and com.android.finalactivity.FinalActivity is full class name. */

Now go to the AndroidManifest.xml of the FirstActivity and Add following line

activity android:name=”com.samsung.finalactivity.FinalActivity” in application tag.

It will work fine.

Method 2. Using action name

For this first go to your Final Activity and Modify the Manifest file like this :

Instead of the action android :name =”android.intent.action.MAIN” Use

action android:name=”finalApplication.intent.LAUNCH”

Now go to your FirstActivity.java and write

Intent i = new Intent("finalApplication.intent.LAUNCH");
startActivity(i);

Here no need to change AndroidManifest file for FirstApplication.

Hope it helps.

Wayanad, Kerala

Hi guys,

Here I am with the new travel blog entry, Last weekend I visited the Wayanad, Kerala. As the Kerala tourism's punch line "God's own Country", I am completely agree with them. Kerala have so much greenery and natural views that you will completely enjoyed. So here are the details if you have any plan to visit this place in future.

How to Reach : If you are going from Bangalore, you can go by Bus. It is on NH 212 and around 270 KMs from Bangalore. As after Mysore, you have to cross the Forest. It is advisable that you plan your journey accordingly as Forest Department closes the door from both side (from mysore side and from sulthan bathery side) around 8 PM. Other way is you can come through Calicut which is around 65 KMs from Wayanad.

When to go : Although you can visit this place anytime in year, but I will suggest you should go in rainy season. As the color of nature will be at its maximum during that period.

What to visit: As I mentioned its the place of Nature View. There are many Water falls, Dam, Peaks, Temples etc. Here I will mention few of the major attractions.

Chembra Peak : This is the Highest point in Wayanad. you have to take the tickets from the Forest depatment, which will cost you 500 bucks(for group). When you start you will think that its no good because you will find a proper road. But after 1.5 Kms walking, you will reach the point from where you will find the main treking, Its very steap and slippery. So be sure you have proper shoes for it and try to take as less thing

as possible. Take water bottles with you, and if you are ok with drinking water falls, then no need to carry bottles. Main view point will be two lakes over there which I find worth going. One of those lakes is in

Heart Shape which have many small fishes in it, in shrt it is awesome thing to do.

Kuruwa Dweep : This is also major attraction. I am not able to write about it as due to rains it was closed or drowned in the water. But if you are lucky you can go there too. Its around 35 Kms from Kalpetta.

Edakkal Caves : This is 27kms from kalpetta which opens 9 AM to 4:30 PM. This place have lots of caves, so you are interested in it, Here is the mystery is waiting for you.

Soochipara Waterfalls : This is 25 Kms from Kalpetta. Nice place to go, you have to trek a little bit to reach the place. But the water flow and the view is good from there.

Banasura Sagar Dam : Distance from Kalpetta 21 Kms. This place is also good. This is Asia's 2nd Largest Natural Dam. Awesome place, View is great from there, you will get some nice snaps from there. Also Speed boat is also available there.

Pookot Lake : This place I didn't like much. As a very small lake is there, in which they have pedal boats and a small Aquarium. The problem with this place is, it is not well maintained at all.

Apart from these places there are few others waterfalls and 2-3 Sanctuary. In this Sanctuary you can find deers, elephants, and lucky then tigers too.

Food : If you are vegeterian, than you can face some problem. As there are only few restaurants. So better you go with some packed stuff with you, so that you wont run out of food. Although you can find Kerala paratha, Dosa with little bit of effort.

Hotels : Guys, book your hotels atleast 1 week before. As we faced a lot of problem to find good hotels as we went in the peak season.

I think this place is worth going once. So go and visit the God's own Country.

Steps to Setup Anonymous FTP Server in Ubuntu using vsftpd

Hi All,

There are many articles on setting FTP server in Ubuntu using vsftpd, but I found that  most of them don't talk about the Anonymous FTP server. So here are the details.
Step 1. Install vsftpd
         > sudo apt-get install vsftpd

Step 2. Need to change the configuration file so that anonymous user can access it.
        > sudo chmod  777 /etc/vsftpd.conf
        > sudo gedit /etc/vsftpd.conf
        > look for anonymous_enable and put its value as YES.
        > if you want to enable local access also, set local_enable as YES.
        > Most important give the directory location where you will put all the files which you want to share.
        for that look for anon_root, if not there then put it there and set its value with location like /home/ftp.

Step 3. your ftp server has been configured now. just start the service
        > sudo service vsftpd restart   or   sudo /etc/init.d/vsftpd start

That's it. just type the ip in browser and you will be able to see all the files in the /home/ftp folder.

android.database.sqlite.SQLiteException: table already exists

Hi guys,

Many times I have faced this problem when I tried to call the db.execSQL(CREATE_TABLE) after  openOrCreateDatabase(DATABASE_NAME,Context.MODE_PRIVATE, null); function. And generally it happens when you are trying to create a table in the same database which already have one or more table in i, other situation is when you are running the same program again and again and the same table is already in the database. So to solve this issue you just need to modify your CREATE_TABLE string(which is creating the table).

Generally we directly use “create table TABLE_NAME” which create problem, so instead of it just add one more thing in it, now create table using string “create table if not exists TABLE_NAME”. It will solve your problem. Hope it will help you.

Bootable Pen Drive : Install Windows using Pen Drive

Hi,

Here is my another experience and blog for it. Today I tried to format my Lappy because it was getting slowed and now and then it was showing some dll errors. But after deleting the partition I came to know that my CD Rom is not working at all. So I have to go for the other option which is installing through pen drive. So here are the steps:
Step 1. go to command prompt. (If you are Vista / Windows 7 user do it in administrative mode.)
Step2. Type Diskpart
Step3. then type LIST DISK
Step 3. It will show you the list of disk. Observe the size. identify which is your pen drive.let us assume it is DISK 1. Now type following commands one by one
>CLEAN
>CREATE PARTITION PRIMARY
>SELECT PARTITION 1     – This 1 remains same always.
>ACTIVE
>FORMAT FS=FAT32
>ASSIGN
>EXIT

Step 4. Copy CD/DVD contents to Pen Drive

> xcopy e:\*.* /s/e/f f:\
where e:\ is your source DVD drive, f:\ is target Pen Drive

Step 5.Change BIOS Settings in the target system
Give your Pen Drive priority as 1. Now just save settings and reboot with Pen Drive inserted in it.
That's it. you are ready with your Windows Pen Drive. :)

The action cannot be completed because the file is open in another program

Hi All,

One more troubleshooting utility I found today, which I would like to share with you. sometimes we face this problem that we are not able to delete the files, it shows one pop-up saying that "The action cannot be completed because the file is open in another program."
This happens because some other application has lock on this, so to remove there is free utility available called "Unlocker".
                 You just need to right click on the file and click on Unlocker option. There the file will be shown as processes, just select and click on "Unlock". Thats it. Now your file is ready to delete. ;)

Remove Write Protection from external Hard disk

Hi All,

Sometimes you face the problem that when you try to remove few files or directories from your external hard-disk, it says that if you want to modify it, please remove write protection from external hard disk. So here is the simple solution, I also found it on some discussion forum.
Step 1. Start -> Run -> regedit.exe
Step 2. Go to
Computer\HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\StorageDevicePolicies
If StorageDevicePolicies is not there then create a new key. 
Step 3. Now Click on StorageDevicePolicies and on the right-hand side there should be a DWORD value labelled "WriteProtect".
Step 4. Do the same with the following two locations (creating any non-existent keys/values along the way):
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control

I hope this will help.
