\adt-bundle-windows-x86_64-20130219\sdk\platform-tools\aapt.exe is invalid

When your are using Android with Csharp or when you are using Monoandroid you will be facing some some error related to aapt.exe missing or aapt.exe invalid . These are common error to Monoandroid developer that almost every one that uses Monoandroid will face .

So Today I decided to get the actual reason of this problem and I sit on my chair to find out the reason and possible solution to this error that may work for everyone . I suffered from this error number of times before but i tried the ways to get rid of it But not today this is the day to get solution of this error .

What are Possible Errors :



  • Error MSB6004: The specified task executable location "C:\Program


  • Files\adt-bundle-windows-x86_64-20130219\sdk\platform-tools\aapt.exe" is 


invalid. (MSB6004) (TaskyAndroid)

The specified task executable location "D:\android-sdk\platform-tools

\aapt.exe" is invalid.


Reason of Above Errors 




This issue is caused by Google changing around the directory structure of the Android SDK with their latest updates and due to these updates old directory structures are creating problem Most probably these error comes after you update your android So when you update your android-sdk then it update the directory structure of android-sdk to new structure of google that allows
aapt.exe to be must present in android-sdk/platform-tools/ but that will be not there because in old directory structure that monoandroid is using aapt.exe is in android-sdk/build-tools/ that's why this error is coming and MonoAndroid Team is applying these changes so  before that we need to figure out this issue to continue our development

Error Solution aapt.exe Invalid


Steps :-

1.  Copy the aapt.exe file from folder \android-sdk\build-tools\17.0.0 to \android-sdk\platform-tools . Here 17.0.0 is your android api you have installed in your sdk it will be what version you installed like :- 8.0.0, 18.0.0

2. Now Also Copy \android-sdk\build-tools\17.0.0\lib folder to \android-sdk\platform-tools\ As there is a file in that directory dx.jar which is also Needed by xamarin

3. Now Everything will be fine ........Cheers!


There is one more error which can let you suffer it is :-

java exited with code 1


Reason of Error java exited with code 1

The reason of this error is in our previous error solution When you copy the aapt.exe file from  \android-sdk\build-tools\17.0.0 to \android-sdk\platform-tools .  and forger to copy or don't copy folder  \android-sdk\build-tools\17.0.0\lib folder to \android-sdk\platform-tools\ then this error comes this is main reason of this error

Error Solution java exited with code 1



 Also Copy \android-sdk\build-tools\17.0.0\lib folder to \android-sdk\platform-tools\ As there is a file in that directory dx.jar which is also Needed by xamarin after copying aapt.exe file

Error : Failed To Update Android SDK

Every Android update contains some tools and advance features . Today I need To update my Andorid SDK to include Google Glass Services in it and enable it to use Google Maps in Andorid Application . In android to use google maps you must have google glass services in your android sdk

Some times it may be possible you sdk not having google glass services . Generally google glass services are available under Extras folder in android sdk Check that folder and click on Install update

But when we update Android SDK we may have an error while updating android sdk . You may have following like error :-

Failed to rename directory 
C:\Media\adt-bundle-windows-x86_64-20130522\sdk\platforms\android-19 to 
C:\Media\adt-bundle-windows-x86_64-20130522\sdk\temp\PlatformPackage.old01.
[find_lock] Directory locked by javaw.exe
And then, a window appears with this message:

-=Warning!=-
The following processes:
- javaw.exe
are locking the following directory:
C:\Media\adt-bundle-windows-x86_64-20130522\sdk\platforms\android-19
Please close these aplications so that the installation can continue.

The main cause of these errors are while we are updating android sdk on one side and on other side our android tools are running or hold by some other background process and we cannot kill that process at it will be automatically started so don't try to do that so the solution to this problem is :-

Follow these simple steps: There are two possible solutions to this problem that may definately solve your problem these both worked for me

Solution1

1. Open your android sdk folder

2. Under that folder you will find temp folder if you are using android studio then path is: C:\Users\<username>\AppData\Local\Android\android-studio\sdk\temp
3. Cut everything and paste it in some other new folder
4. Rerun the sdk and now and update

Solution2

1. First Make a copy of the \tools folder, name it something like \copy. So you should have c:\android-sdk-windows\copy.
2. Now run android.bat from the \copy folder with Admin privileges.
3. This should prevent the issue with items currently being open in the \tools folder.
4. Now cheers..

Grid System In Bootstrap

Grid systems are used for creating page layouts through a series of rows and columns that house your content. Bootstrap's Grid system has done a lot of ease for developers Instead of doing calculations for div's like they do before bootstrap technology they can easily divide the page into columns and rows and design the page according to it .

Here's how the Bootstrap grid system works:

  • Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding. A container will contain all your divs
  • Use rows to create horizontal groups of columns.
  • Content should be placed within columns, and only columns may be immediate children of rows.
  • Predefined grid classes like .row and .col-xs-4 are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.
  • Columns create gutters (gaps between column content) via padding. That padding is offset in rows for the first and last column via negative margin on .rows.
  • The negative margin is why the examples below are outdented. It's so that content within grid columns is lined up with non-grid content.
  • Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three .col-xs-4.
  • If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
  • Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, applying any .col-md- class to an element will not only affect its styling on medium devices but also on large devices if a .col-lg- class is not present.
