How to Create Apk Files on Androids
Do you know writing an application for an Android device does what? The answer is .apk file is automatically produced by the application. The file can only be used with a PC or MAC emulator. Remember .apk file won’t work to install and run the application on an Android device. Any idea why this happens? It happens because Google requires a certificate that tells where the application comes from. Your traceable e-signature is used by Google in order to cut down on phone users installing fraudulent applications. You can make the application usable by simply signing your application using a keystroke.
Step by Step Guide
You can make a personal keystore using JavaSDK. The certificate must be created by the developer. If you are using a PC or Linux OS, you will need to install JavaSDK.
Wait for the JavaSDK to install and when it does, open it and go to keytool applications. You will be prompted to provide a password for the keystore. You need to choose a strong password and don’t forget to write it down on a piece of paper as you will need it.
Now you are required to export your application. You simply need to right click on your project and choose “Android tools” then “Export unsigned application package”. Exporting the application to a directory and copying the location to your clipboard.
Now open your keystore and sign your application. Click “Open” and go to your application directory. You need to execute the .sh file, the .apk file and enter your password.
The application is signed the moment you enter your password. Now you will upload the application to a server, install it on your Android device and publish it on the Android and Amazon marketplaces.
