Android on Kenno's Open Note

Updating Nexus 7 to Lollipop using sideload

Sat, 13 Dec 2014 22:16:57 +0000

This post is a note to remind myself how to manually flash Android firmware on a Nexus device.

Step 1, download the firmware to your computer. I downloaded Android 5 from:

Step 2, connect Nexus 7 to the computer. Mine runs Ubuntu 14.10, and I already downloaded Android SDK.

Make sure that “Developer Options” is enabled. If it’s not, go to Settings -> About tablet. Then click on “Build Number” 7 times.

Android Studio Cannot Resolve Symbol R

Tue, 25 Nov 2014 15:36:52 +0000

I just got this problem today when I opened an Android project with Android Studio. Basically, anywhere there’s a reference to R, for example R.layout.footer_view, Android Studio will complain that it cannot resolve symbol R.

The fix is surprisingly easy. All I need to do was running Gradle clean and Gradle build.

Fortunately, there’s a way to fix this problem by opening ‘eclipse.ini’ file, in my case:

How to replace default fonts in MIUI rom

Sun, 24 Jul 2011 02:35:46 +0000

MIUI (1.7.22) uses Arial as the default font. If you hate it as I do, here is how to change it.

I assume you have adb working. We are going to replace only 2 fonts - Arial.ttf and Arial-Bold.ttf.

First, let’s back up the old fonts just in case thing didn’t go well as we want to. (I learned this the hard way, and keen to avoid it at all cost)
