Initial Steps in Android Programming

Reading Time: 2 minutes

Initial Steps in Android Programming are following:

We need to install Java JDK first. Next step is to do android studio installation. But even on this early step, problems might appear, see the figure bellow.

JDK-if-missing

So we need to set environment variable named JAVA_HOME

ev01

Advanced system settings → Advanced → Environment Variables → JAVA_HOME

JAVA_HOME-variable-path

and also change path:

;%JAVA_HOME%\BIN

After that, problems might appear. For example, one thing that can happened is that android studio doesn’t find Java development kit (JDK).
In that case, we must go into folder that path is something like:
C:\Users\admin\.AndroidStudio1.3\conig\options
and find jdk.table.xml file. This file should be changed as follows
<homePath value=”C:/Program Files/Java/jdk1.8.0_60″/>

Next important step is to verify if your mobile device fully communicate with Android studio, i.e. you must test Android Studio on a Physical Android device, Checking this is best by using adb logcat command. ADB is abbreviation for Android Debug Bridge. So find path for your adb.exe. It suppose to be something like this:

E:\Users\admin\AppData\Local\Android\sdk\platform-tools

Two major commands for checking health of mobile device – PC communications are:

  • adb devices
  • adb logcat

If response on adb device command is unauthorized and on adb logcat is waiting for device, then you haven’t installed drivers of your mobile device to your Windows8.1. See figure bellow.

adb-logcat

If this is the case, you MUST install driver for your mobile device on your Windows8.1, although you can access your mobile with windows explorer. This is because for accessing mobile device you can use universal USB driver, but this is not enough for programming the device in Android studio. Install your mobile device drivers first:

Mobile-driver-install

Once when driver is installed, you can start with programming.

Mobile-driver-installed

So, in order to start with the pleasure of programming your mobile device in Android studio, you must test Android Studio on a physical android device, and also fix all problems with how to point to valid JDK.
