Android Development Notes

Android Development Screen shots Notes, showing my settings, and most especially space costs on my dual OS laptop.

I dual boot into Windows 10 or  Ubuntu 16 on my laptop, l find the later faster and more Android sdk development simpler since l have to disable Hyper-V which l need on Windows 10 if l setup my full Android development on it – including emulator for testing.

Note, the complete tools below l chose and use take a lot of space. In my case, 30Gb, so plan accordingly.

Choice of SDK platforms.

My current phone is the LGG5 – running Android 7.0, however l also own an older Nexus 6 [no sim card/wireless plan] which l use for Android development testing running Android 7.1.1 [google nexus phones get the latest android releases frirst, unfortunately at least the nexus 6P not 6 is required for Android Oreo/8] 🙁 , and one of my target platform is Ikechukwu’s older samsung galaxy tablet which runs Android lollipop 5.0.1

I also chose Android MM – Marshmellow 6.0.1 since l have a tester using that version residing in Jos/Lagos on his phone – onijec [click here for his twitter link].

I want to test developing a small birthday countdown app for Ikechukwu, see if this works on multiple Android versions, test and use my google developer account/playstore and non playstore app distribution – before diving into more deep stuff like geo location based apps l am more interested in.
