Enable Android Debugging on Samsung S5

On newer phones the manufacturer hide away the debug option, maybe to prevent regular users from enabling it without knowing what risk it could expose.
On the Samsung S5 you have to navigate to the System Settings / About and click 5 times on the About label.

Connecting Samsung S3 S5 to Ubuntu for debugging Android Apps

Some things did not change since the early coding days with Linux and Android Phones , you still need to tinker with system files to allow USB access to the phone. Without the below steps you get “no permission” and offline errors in the Android Device Monitor.

  1. Out-of-the-box the phone does not allow debugging. You need to find the developer options under phone settings and specifically allow USB debugging.

Android Development Restarted

It has been quite a while since I touched an Android phone the last time for code projects. I got in contact first time with an Android phone during an open source conference in 2008 in Sydney when I met Chris DiBona (Director of Open Source at Google). Announcing the SDK 1.0. Soon after I got the G1, aka HTC Dream phone which was the first Android phone available. I could not even imagine this platform would be so widespread adopted and pushed in the years to come. I was even thinking about the investment that time, spending a few hundred dollars on a phone that might be just a experiment. In 2010 I also bought the Nexus One.

Anyway I created some apps for personal use, experimented with the apps market but due to other development and work focus lost it out of sight and just remained normal Android user.

Now my interest returned, at least to update my knowledge about this technology. Today things are becoming a bit easier (IDE, documentation) but also more complex, mainly due to the massive range of devices and manufacturers which makes screen design quite challenging, but also to security concerns as more spam and junk apps are around, users are no longer so flexible with the app security settings.

Coding becomes more convenient, now Android got its own IDE, the Android Studio. After an initial download and subsequent additional downloads of required packages you can start with your projects straight away.

With Ubuntu just just download the linux package, make sure you have a JDK installed, and execute the studio.sh shellscript in the bin folder.
