Using Ant Build :
This Process are pretty easy for building signed apk .If you are using Ant, you can enable release mode by using the release option with the ant command Line Interface.

For example, if you are running Ant from the directory containing your build.xml file, the command would look like this:

$ ant release

First we need to insure placing proper file in our project directory.if you create project in command Line Interface than both file are auto mated create in project property.

Before run ant build place this & build.xml


Run android update project -p .
Create file manually with the following contents
Tell ant where your keystore file :
Now you just need to tell ant where the keystore file is by going to your android project folder (For phonegap it’s in platforms/android) and create an ant.

properties file and put the following in it:

Where equals the path to the keystore file starting at the C Drive if you’re on windows and it’s a relative path starting from the location of the ant.

properties file if you’re on mac (example:, and key.Alias is whatever you setup when you created the keystore.

Build With PhoneGap:

In platforms/android/bin you should have:
Build Using Android Studio:
On the main menu, choose Build | Generate Signed APK. The Generate Signed APK Wizard starts.

  2. Specify and confirm the password to access the keystore.
  3. Configure the release key to be generated by filling in the data in the Key area. The procedure is identical no matter whether you are using a wizard or an artifact definition, see Generating a Signed Release APK Using a Wizard: Generating a new release key for details.
  4. Click OK when ready. IntelliJ IDEA brings you back to the first page of the wizard, where the keystore location, the key alias and passwords to access them are filled in in the corresponding fields.
Click Next.  IDEA brings you to the  wizard.

  2. To have IntelliJ IDEA obfuscate the application during packaging, select the Run ProGuard check box and specify the location of the proguard.txt configuration file. The file is generated during project creation and is stored in the project root. IntelliJ IDEA suggests this default location in the Config file path text box. Accept the suggestion or specify a custom configuration file by clicking the Browse button and selecting the required file in the dialog that opens.
  3. Click Finish to have the package generated and signed. When the package is generated, IntelliJ IDEA informs you about it in an information message.To open the folder where the generated .apk file is stored, click the Open File Location button.
