Uninstall Android Apps Which Says “Uninstall not Successful”

By 1 Comment

One of the problems Android users face is that they are unable to uninstall some particular apps from their devices. When you try to uninstall Android app from the Settings, it says “Uninstall not Successful” like in the Screen-shot below where I am trying to get rid of AirDroid.

Uninstall not succesful error in Android
I faced the same problem a little while ago and I almost believed that I can’t uninstall android app because of this nasty Android uninstall not successful error. I was like I have to see these unwanted apps in my drawer and they’ll consume my mobile’s memory forever. But fortunately while I was just trying to find any way to uninstall these apps, luckily I figured it out.

Why you’re unable to uninstall some apps?

The reason is that those apps are running as Device Administrator. Some apps ask for permission to run as the Administrator of your Android device when you launch them. So, there’s no way to uninstall such apps until you disable them as Administrator.

Uninstall Apps which says “Uninstall not Successful”:

It’s very easy to Uninstall Android Apps which say “Uninstall not Successful”. All you have to do is just unselect them from Device Administrators.

Step 1: Unselect the app from Device Administrators:

Go to “Settings” of your android device and the tap on “Location and Security” options from the list. There you’ll find an option “Select device administrators” under “Device administration”, open it. You’ll see a list of apps which are running as Device Administrator. Now unselect the app which you want to uninstall but unable to do so.

Step 2: Try Uninstalling the App:

Now use the normal method of uninstalling the app from Settings> Applications> Manage Applications. You’ll be able to uninstall the app which you un-selected in the First Step.

That’s it! It was easy. Now you don’t have to worry seeing uninstall not successful error any more. Like, you don’t have to worry about unwanted and not delete-able Picasa Photos in the Gallery of your Android device.  You can remove them easily.

[How To] Solve “command not found: ^M” Shell Error

By Leave a Comment

Terminal-icon-shell-linux-unixProblem with command not found ^M:

The other day I was trying to execute this simple shell script. The shell script was using Z shell. when I tried to execute the shell script, it threw me the following error:

script.sh:2: command not found: ^M
script.sh:4: parse error near `then^M’

After digging a little bit in to the problem, I found that this character ^M represents an extra useless space. But this was the weird part. There were many spaces in the shell file but it was quite common and most certainly not useless. Even if I tried removing the “troublesome” extra space, it keep on throwing the same error for some other extra space.

Reason:

The reason which was causing this error was that I had used Windows explorer to write the shell script. What I meant that I had my Linux network drive mounted in Windows. I wrote the shell scripting in Windows, saved it as .sh file and tried executing it. And that is where it went wrong.

You see, when I used Windows to write the program, it saved it in Windows format. And this is why Linux could not encode it properly. A simple file command showed the “true color” of this “traitor Windows” file.

Solution:

Simple most solution to get rid of this error is to convert the Windows file to Unix (read Linux) format. dos2unix tool comes handy in this case. It comes pre-installed in many Linux systems. Here is how to use it:

dos2unix script.sh

where script.sh could be your shell script file name.

The output of the command may look like this:

dos2unix: converting file script.sh to UNIX format …

That is it. No need to do anything further. The next time you execute your shell script, it will not show the ^M command not found error. Cheers :)

How To Solve: External SD Card Not Detected By AirDroid

By 17 Comments

AirDroid is my favorite way to connect my Samsung Galaxy S2 to my laptop running on Ubuntu Linux. AirDroid is a fantastic app that connects your computer with Android over wireless. Best thing, you can access it over any web browser. Lately, I bought an external memory card of 32 GB and when I connected my laptop to my Galaxy s2 using AirDroid, I was surprised to see that AirDroid could not recognize the external SD card.

To solve the problem and “force” AirDroid to recognize the external SD card, here is what you can do.

1. Click to “Files” icon on AirDroid desktop
2. Open the “System” folder (ignore the warning)
3. Search for “mnt” folder. This folder is used for mounting all the drives (read cards).
4. Open “mnt” folder. here you should see some folders like System, SD Card and a folder named after your external SD card. By default it is called External SD. Enter the folder and you can see all your files stored on the external SD card.

Next time on wards, you can access them under Files folder and it will directly show you the External SD Card:

Cheers :)

Ten things idiots do on Facebook. Are you one of them?

By 18 Comments

I am forced to write this post after seeing so many “idiots” around me on Facebook doing weird things. Like real world, there are few etiquettes which one should follow in the cyber world, but again, like real world, some people just don’t give damn to the manners or they just are not aware that such manners do exist. Believe me there are lots of stupid things people do without even knowing it. In this post I have compiled top 10 things what idiots do on Facebook:

1. Use caps lock all the time:

How many time have you seen a person posting in upper cases? a few time for sure! Using Caps lock is equivalent to shouting but few people around us prefer to “shout”, always. They forget that they can turn that caps lock off or they simply don’t care like these two jerks here:

2. Like your own status, link, photos and whatever:

Seriously, what are you? A self obsessed narcissist? How does it sounds in Facebook ticker: “XYZ likes his/her own status”. Give a chance for others to like your status and links. Don’t be a despo.

3. Auto Update Facebook status from Twitter:

One needs to understand that Facebook and Twitter are two different kinds of Social Networks. On Twitter you keep on sharing stuff every minute, it is acceptable. Facebook is not the same. You don’t go around flooding your friends’ feeds by auto posting all your tweets as your Facebook status.

4. Spread Hoax:

I know Facebook encourages to share. I also know that you are a concerned citizen but it doesn’t mean you will share whatever craps you find might be “helpful” for public. These hoax include Facebook charging money, hidden camera stories and Facebook donation for sharing pictures and other stuff like this. Use your mind and Google (if you have doubts, check on Hoax-Slayer) before doing such idiotic stuff.

If Facebook has to donate money it will simply donate it. It won’t ask and keep an account of that gross looking picture. Grow Up.

5. Add any fake profile in the friend list:

Yes, there is a very beautiful girl in a sexy pose on the display pic and that is the foremost sign that it could be fake. Oh! She has more than 1000 friends. Most certainly fake. But you don’t care about it because you are a one despo looking for single girls all over the Facebook and/or internet. So you add or accept the request and go on commenting on her pics and liking whatever craps that profile (most probably used by an ugly-looking male) posts. Find out more about how to find fake Facebook profile.

6. Play Farmville/Mafia Wars and such other craps:

Fine! You like to play these games but why bother others? Why send them request to save your lost sheep in Farmville? Most of the people don’t give a damn if you were attacked by some goons in Mafia Wars. If you are such a game addict, create a separate Facebook profile just for playing these games and stop bothering other people in your friend-list before they start blocking you.

7. Update each and every activity on Facebook status:

So, you get up and wish Good Morning to everyone. And then you tell them what are you eating in breakfast, what are you watching, what are your day’s plan. Keep updating it hourly basis. More, also tell them how many times you pooped. Describe that in detail too! For God sake, get a life. Updating the status about interesting things, news, events or funny quotes is one thing but it is not your diary where you record each and everything.

8. Share your love, break-ups and fights:

Aww… You are a love bird. You lover her/him so much that you keep on posting love quotes throughout the day.

Oh! you had a fight. Both of you are not on talking term and now updating your Facebook status hitting out at each other directly/indirectly.

Oops.. you broke up. Now the whole world has to suffer from sad heart-broken status update.

Grow up attention seeker.

9. Pay tribute to every celebrity (without thinking of course):

Though you might have never been able to buy an original Apple product but it was your social responsibility to pay homage to Steve Jobs. You updated your status, changed your profile pic to apple or of Jobs. You shared photos praising Job’s vision and achievement.

Now you see other pics complaining that there are millions of children dying of hunger. You share the pic with hungry child on one side and Steve Jobs on the other. How great of you.

Now comes Dennis Ritchie. You might have never used Unix all your life, never programmed in C and before this day you never knew that there exists such a person but paying a tribute is a must for you. Stop being a &%$#@.

10. The rest falls in this category

There are many more crazy stuffs. List is long and increasing. This point is left empty to take care of rest such things. I encourage you to share the 10th point.

How to Solve: Backspace key does not work in Mozilla Firefox in Ubuntu Linux

By 3 Comments

Problem:

Most of us are used-to of using the backspace key to go back to previous page while browsing in Mozilla Firefox. By default, Firefox in Linux doesn’t provide the functionality of pressing backspace for going back to previous page which is quite irritating as it forces one to use the mouse.

Solution:

A little tweak is required in Firefox configuration to make it work. Here is what you need to do:

  • Open Firefox new tab
  • Type about:config in the address bar
  • Click yes to the warning
  • Now search for browser:backspace_action
  • Double click on it to change its value from 2 to 0

Alternate Solution:

There is another way to go to previous or next pages in any browser, in any OS and that is by using arrow keys. The shortcut is as follows:

  • Alt-Left = back
  • Alt-Right = forward

Questions and suggestions are most welcomed. Cheers :)

How to fix: Android Samsung Galaxy S2 not recognized on Linux

By 51 Comments

Problem:

I was facing problems connecting my Samsung Galaxy S2 on Ubuntu, which is particularly annoying bearing in mind the total lack of support by Samsung for Linux (even Kies is of no use). Strange enough, it works flawlessly on Windows 7, where it recognises it instantly and I can transfer files between my phone and computer.
When I plug it into my Linux machine, it is recognised and I can see the contents of the root of /sdcard and the SD card but I cannot access the contents of any file or folder as all the folders are empty.
When I connect my phone to USB there is no “mount USB” option but just MTP application in the home screen. [Read more…]
