If you change your login password you might find that you get prompted for your "default keyring" password, this can be annoying, and sadly it isn't obvious how to change this to be the same as your new login password (or another password if you are being ultra secure!).

• Go to Passwords and Keys


• Click on the Passwords tab


• Right click over Passwords: login


• Select Change Password

If you change your password to the same as your login password you won't get prompted for your default keyring password when you log in.

Or else you can delete it

After you finish configuring your application you can build it into a release-ready .apk fle that is signed and optimized. The JDK includes the tools for signing the .apk file (Keytool and Jarsigner); the Android SDK includes the tools for compiling and optimizing the .apk file. If you are using Eclipse with the ADT plugin or you are using the Ant build script from the command line, you can automate the entire build process.

In preparation for signing your application, you must first ensure that you have a suitable private key with which to sign. Following Keytool command generates a private key:

$ keytool -genkey -v -keystore my-release-key.keystore
-alias alias_name -keyalg RSA -keysize 2048 -validity 10000

Running the example command above, Keytool prompts you to provide passwords for the keystore and key, and to provide the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore. The keystore and key are protected by the passwords you entered. The keystore contains a single key, valid for 10000 days. The alias is a name that you — will use later, to refer to this keystore when signing your application.

The Export Wizard performs all the interaction with the Keytool and Jarsigner for you, which allows you to sign the package using a GUI instead of performing the manual procedures to compile, sign, and align, as discussed above. Once the wizard has compiled and signed your package, it will also perfom package alignment with zipalign. Because the Export Wizard uses both Keytool and Jarsigner, you should ensure that they are accessible on your computer.

To create a signed and aligned APK in Eclipse:

1. Select the project in the Package Explorer and select File > Export.
2. Open the Android folder, select Export Android Application, and click Next.The Export Android Application wizard now starts, which will guide you through the process of signing your application, including steps for selecting the private key with which to sign the APK (or creating a new keystore and private key).
3. Complete the Export Wizard and your application will be compiled, signed, aligned, and ready for distribution.

I suppose you know how to create a Phonegap project and also how to add a plugin into the project.

First download the required code from here.

Add the "Ads" folder to your plugins list.

To do this, right-click on the Plugins folder in Xcode and select to “Add Files to…” the folder.


Navigate to the Ads folder, and select the folder. Check “Copy items

into. . .” and “Create groups for. . .” A ChildBrowser folder is added to the Plugins folder. Copy the content of "js" folder to desired location.

Then update the plist to use the plugin

In Supporting Files > PhoneGap.plist, add under Plugins

(click the down arrow to the left of Plugins, then click on the + symbol to open a new row):

Key: SAiOSAdPlugin

Type: String (default)

Value: SAiOSAdPlugin

See the "index.html" for initialization of the code.

Now, to display the Ad, call "showTheAd(true)"

and whenever you want to hide the Ad call "showTheAd(false)"

Make sure you link in the iAd framework to your project. Do this by going to your project settings in Xcode. Then select your target and in the right pane go to "Build Phases." Then in the "Link Binary with Libraries" section hit the "+" button to add more frameworks. Select iAd.framework click "Add" and then rebuild.

This a html code that can be added to website to share some content on  GooglePlus

You can use any image(but select a related one). By clicking on the image, content will be posted

on the users G+ account. Consider the following samople code

Also the proper description will be posted, along with the link.

This error occurs due to 32bit incompatibility on your system.

One solution is to install the 32 bit compatibility on your system :

sudo apt-get install ia32-libs
