    Solution:

     

    sudo chown -R $USER /usr/local/

    FAILURE: Build failed with an exception.

    * What went wrong:
    Execution failed for task ':CordovaLib:processDebugResources'.
    > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/home/arulmanickam/adt-bundle-linux-x86-20131030/sdk/build-tools/23.0.2/aapt'' finished with non-zero exit value 127

  6. Failed to find 'ANDROID_HOME' environment variable

    i have this error when i am trying to build

    [Error: Failed to find 'ANDROID_HOME' environment variable. Try setting setting it manually.
    Failed to find 'android' command in your 'PATH'. Try update your 'PATH' to include path to valid SDK directory.]

     

    Solution

     

    You have permission errors. My guess is that you tried to run the script as root rather than sudo. When running the script you have to run it as your user account using sudo.

     

    change owner permission all files & folder to your current login user .

    • Your android sdk
    • Your ionic or cordova project files

    dont run as admin or run using sudo

  7. Laravel 5.1 PHP DOMXPath() class not found

    I'm using PHP's built-in DOMXPath() class to do some simple web-scrapping. However, it works on my 4.2 site, but not my 5.1 (both are on same installation of PHP).

    Here's the error:

    Class 'App\Http\Controllers\admin\DOMXPath' not found

     $list1 =newDOMXPath();

     

    In Laravel 5.1 you must prefix the class name with the global namespace prefix '\'.

  9. Add Magento Admin User Using MySQL Script

    This script quickly adds a Magento Admin user directly into the database. It is possible to run this script from the command line or by copying and pasting into phpMyAdmin. Just make sure to edit the following fields with your personalized data and import. Most of these fields are trivial, I’m just listing them so you don’t miss anything.

    1. Set the salt portion of your password. You’ll rarely need to change this. If you do, just use two lower case letters of your choice.
    2. Set your password. At least 8 characters in length and at least one digit.
    3. Firstname: Enter admin’s first name.
    4. Lastname: Enter admin’s last name.
    5. Enter email of admin user.
    6. Enter username where ‘myuser’ is set. Notice ‘myuser’ shows up in two places.
    7. Enter Firstname again. This is more symbolic to label the rule.
