How to set a full screen Wallpaper on your Android device? [ROOT]

How to set a full screen Wallpaper on your Android device? [ROOT]

I have a rooted Android device running CM 10.2(Android 4.3.1). I wanted to have the Nexus 5 background without installing an applications to "set the wallpaper" or have it cropped by setting the wallpaper manually.

I have provided the Nexus 5 wallpaper above. Make sure to rename the wallpaper:

mv wallpaper.jpg wallpaper

Push the wallpaper to your device:

adb push wallpaper_info.xml /data/system/users/0
adb push wallpaper /data/system/users/0

Make sure your ADB shell is running root:

adb root
adb shell

Make sure the new files have the write permissions:

chmod 666 /data/system/users/0/wallpaper_info.xml
chmod 666 /data/system/users/0/wallpaper

Make sure the new files have the right ownership:

chown system:system /data/system/users/0/wallpaper_info.xml
chown system:system /data/system/users/0/wallpaper

How to take Screenshots with Google Glass?

In order to take screenshots with Google Glass as of now is to simply do it via the command line with ADB!

Check out these two commands that can easily take care of this for you:

How to view your Google Glass or Android Device on your Computer?

How can you view your Google Glass or other Android Device on your own Computer?

You can view your Google Glass screen or Android device using the Android Screen Monitor!

Download the ".jar" file here:

Here is how to run the ".jar" file from Terminal:

java -jar asm.jar

Here is how it looks!

How can you get started with your Google Glass?

Getting started with Google Glass!

When using Google Glass it is best to use an Android device, therefore you can maximize your abilities through Bluetooth and the MyGlass Android app with the Google Glass.

When you first turn your Google Glass on, here is what you will see, the time and "ok glass":

Download the MyGlass application for your Android device: Naturally your Google Glass will have Bluetooth already enabled, which makes it easy to pair with your Android device. Take a look at the application and run through the setup to get started with Google Glass!

Pairing the Google Glass and the MyGlass app allows for notifications to be sent directly from your device to your Glass! Watch the Official Google video here:

OpenQuartz: Google Glass Open Source Development

OpenQuartz: Google Glass Open Source Development

Much like quartz sand is the main ingredient in most commercial glass, we want OpenQuartz to be the main "ingredient" in the future development for Google Glass!

Find the repository here:

Here is an OpenCV Android implementation of Face Detection!

Example Applications for Google Glass(/example-apps)

  • GDK
  • Misc
    • Glass Preview - Jared Burrows
      • "Hotfix" for Google Glass camera preview - post-XE10
    • Face Detection - Jared Burrows
      • "Hotfix" for Google Glass camera preview - post-XE10

Google Glass Application Source Code(/glass-source):

UPDATE(11/19/13): GDK is now out! You can still easily decompile applications using this method.
Since the GDK is not yet released, we can look around how the current Google Glass Android applications were compile by breaking them down. The decompiled Google Glass applications are included. Here are a list of tools to decompile the native APKs:

Third Party Applications(/third-party):

Here are helpful applications to install on your Glass in order to start testing and developing.

Basic ADB Usage(From Terminal or CMD Prompt):

Since there is no "Google Play" for the Glass yet, we have to side load Android applications for now.
  • Installing/Uninstall Applications(.apks):
    • adb install -r FILE.apk
    • adb uninstall FILE.apk
  • Running the Application:
    • adb shell am start -n PACKAGE.NAME/.MAIN.ACTIVITY.NAME
  • List all Packages on your Android Device:
    • adb shell pm list packages -f
  • List all Relative Information about your Android Device:
    • adb shell dumpsys
      • adb shell dumpsys battery
      • adb shell dumpsys wifi
      • adb shell dumpsys cpuinfo
      • adb shell dumpsys meminfo
        • adb shell dumpsys meminfo PACKAGE.NAME
    • adb shell cat "/system/build.prop" | grep "product"
  • Show the AndroidManifest for an APK
    • aapt dump xmltree FILE.apk AndroidManifest.xml
  • Screenshots from Commandline
    • adb shell /system/bin/screencap -p /sdcard/screenshot.png
    • adb pull /sdcard/screenshot.png screenshot.png
