Terminal: adjusting prompt and PATH variables

You will find yourself using Terminal a lot, so it is important that when it opens it is just right for you.
To change your settings in Terminal, I change .profile, but you can go specifically for .bashrc
I use GNU nano because I hate vi.

Getting Info About APK

Often you have apk that you need (e.g. package, version) info for, but you have no documentation about it. This little command gives you a lot of info.

$ aapt dump badging  someapp.apk
package: name='com.someapp.xyz' versionCode='1' versionName='1.1'
sdkVersion:'15'
targetSdkVersion:'17'
application-label:'SomeApp'
application: label='SomeApp' icon=''
application-debuggable
uses-feature:'android.hardware.touchscreen'
uses-implied-feature:'android.hardware.touchscreen','assumed you require a touch screen unless explicitly made optional'
supports-screens: 'small' 'normal' 'large' 'xlarge'
supports-any-density: 'true'
locales: '--_--'
densities: '160' '240' '320'

Updating Android SDK from command line (Terminal)

You may want to create a script "Update Android SDK.bash" that quickly gets you up to speed without starting IDE (e.g. Eclipse) UI.

echo 'Android SDK home ' $ANDROID_HOME

$ANDROID_HOME/tools/android update sdk --no-ui --all --force 

Notice that it will ask you several times to click letter 'y'

Do you accept the license 'android-sdk-license-bcbbd656' [y/n]: y

You start the Apache server by:
$ sudo apachectl start


Re-deploying your code:
remove old:
$ sudo rm -r /Library/WebServer/Documents/my_project
Make directory:
$ sudo mkdir /Library/WebServer/Documents/my_project
copy new code in:
$ sudo cp -r /Users/uki/Documents/workspaces/.../my_project/* /Library/WebServer/Documents/my_project

you can view your local server at:

Updating Android JellyBean 4.2

Updating Android JellyBean 4.2 using ClockworkMod CWM & cyanogenmod for Android Developers.

If you are a Mac user you might be frustrated that there is no ODIN3 (Window software).
Actually, it is very easy with adb tool that every Android developer uses.

I am starting with stock Samsung Galaxy Tab 10.1 Android 3.0.1 (from Google I/O).

STEP 1)

Get cyanogenmod for your SPECIFIC device, get most stable version there is:

http://wiki.cyanogenmod.org/w/Devices#vendor=;

Examples:
Galaxy Tab 10.1 Wi-Fi only model
http://wiki.cyanogenmod.org/w/P4wifi_Info
I got cm-10.1-20130522-NIGHTLY-p4wifi.zip

Samsung Galaxy Tab 7 T-Mobile:
http://get.cm/?device=p1
http://download.cyanogenmod.org/?type=stable&device=p1
Stable cm-9.1.0-p1.zip

Motorola Droid2
http://download.cyanogenmod.org/?type=stable&device=droid2
cm-7.2.0-droid2.zip 

STEP 2)

Get Google Apps for your version of above
- cm-10 == Android 4.2.2
- cm-9 == ICS
- cm-7 == Gingerbread

you can easily find by searching "gapps-jb-2013"
http://rapidshare.com/files/3580601868/gapps-jb-20130301-signed.zip

STEP 3)
Get ClockworkMod CWM recovery.img

http://www.clockworkmod.com/rommanager

EXAMPLES:

Samsung Galaxy Tab (T-Mobile)

http://download2.clockworkmod.com/recoveries/recovery-clockwork-2.5.1.8-tmobile_tab.zip

STEP 4) For Samsung: Inspect if there is no update in Kies (USB Debugging OFF), you can use thier for file transfer, too

STEP 5) Transfer there 2 ZIP files to /sdcard/  (USB Debugging ON)
- gApps
- cm-
Example:
uki:platform-tools uki$ adb push ~/Documents/Android/Samsung_Galaxy_Tab_7_TMobile/cm-9.1.0-p1.zip /sdcard/
3038 KB/s (144260310 bytes in 46.360s)
uki:platform-tools uki$ adb push ~/Documents/Android/Samsung_Galaxy_Tab_7_TMobile/gapps-ics-20120317-signed.zip /sdcard/
3263 KB/s (54485532 bytes in 16.304s)
uki:platform-tools uki$

I am showing 3 zip files because I tried older gApps previously.

STEP 6)
Turn OFF tablet by holding POWER button

STEP )
START device in fast boot mode (USB icon):
- hold VOLUME-DOWN (closer to power button) and press POWER button until device boots,
- select Fastboot, NOT download by pressing volume-down, make selection by pressing VOLUME-UP

STEP )
See if you can see your device

uki:platform-tools uki$ fastboot devices 

288420043805517 fastboot

If you see similar (number) line as above, you are good to proceed.

STEP )
Install ClockworkMod CWM tool

uki:platform-tools uki$ fastboot -u -S 0 flash recovery /Users/uki/Downloads/recovery-clockwork-6.0.3.1-p4wifi.img 
sending 'recovery' (4844 KB)...
OKAY [  0.341s]
writing 'recovery'...
OKAY [  0.605s]
finished. total time: 0.946s
uki:platform-tools uki$

STEP ) 

uki:platform-tools uki$ fastboot reboot

rebooting...

finished. total time: 0.000s

The Tablet should start and be healthy.

STEP )
uki:platform-tools uki$ adb reboot recovery  

The Tablet should start with ClockworkMod Recovery menu. If is does not start it same as bafore (POWER + VOLUME DOWN) and select recovery (icon with box expanding)

STEP )
select  - backup and restore (move with Volume UP, select with pressing Power button)
select  - backup (will take a while, but it is VERY IMPORTANT)
...
Backup complete!
*** Go Back ***

STEP )
wipe data/factory reset

*** Yes...

STEP )
select advanced
select - wipe Dalvik cache

*** Yes
*** Go Back ***

STEP)
select install zip from sdcard
choose..   cm-10.1-2013......-p4wifi.zip from sdcard
*** Yes...


STEP )
install gapps-jb-2013.....zip from sdcard

STEP )
restart, press POWER button for 10 seconds
- unplug,

If it fails recover backup (should not happen)

STEP)
IMPORTANT!!! To enable "USB Debugging" and other {} Developer options:
Settings -> About tablet -> CLICK "Build number" line 6 times!!!!!!

I guess the last one is for the code gurus that spent 6 years in the high mountains writing this, one click per year. :)


STEP )
Update Android SKD Manager to versions 16 & 17

SUCCESS!

KNOWN BUG:

The keyboard closes after first character typed, which makes impossible to use the keyboard. 

To fix it go to: 

settings -> language & input  -> click on settings icon next to "Android Keyboard (AOSP)" -> under TEXT CORRECTION

• set 'Auto-correction' to 'Off' 
• set 'Show correction options' to 'Always hide'.

The SWYPE will still work, but it will not show auto-correction words on top, it is a minor setback. When I don't get a correct word in Swype mode, I have to type it character-by-character.

Default Google Account

I have a couple of Google accounts:
- my name @google.com
- my company email which is also done via Google

To change DEFAULT google account I had to sign OUT from all and sign in FIRST with the one I want as default.

For some Google entities I had to do it in reverse as my new email did not work with them.

Getting Google YouTube API key

You should follow steps in here:
https://developers.google.com/youtube/android/player/register

with small exception since the command returns error:

$ keytool -list -v my-release-key.keystore
keytool error: java.lang.RuntimeException: Usage error, /Users/uki/Documents/Dropbox/Android_Keychains/my-release-key.keystore is not a legal command
java.lang.RuntimeException: Usage error, /Users/uki/Documents/Dropbox/Android_Keychains/my-release-key.keystore is not a legal command
    at sun.security.tools.KeyTool.parseArgs(KeyTool.java:375)
    at sun.security.tools.KeyTool.run(KeyTool.java:171)
    at sun.security.tools.KeyTool.main(KeyTool.java:166)

instead use the following:

$ keytool -list -v -keystore "my-release-key.keystore"
Enter keystore password:  

• Make sure you use option -v to get both SHA1 and MP5
• Make sure you quote the file path to your keystore file.
