Android: get sha from *.apk file; validate *.apk content; check apk integrity

The apk file might get destroyed when it's transferred through a network. If the file is signed with a certificate (most Android applications are signed by the publisher) you can check the file integrity from the command line before installing the application. The following methods check the certificate validity as well as validate apk file contents.

keytool -list -printcert -jarfile app-sa.apk

Ubuntu mount nfs share

Ubuntu does not come with nfs server so we need to install it:

$ sudo apt-get install nfs-kernel-server

Then we can mount nfs shares like this:

$ sudo mount 1.2.3.4:/home /home/user/nfs/home


to check whether the share mounted successfully:

mount -t nfs

Build Android apps as Chrome apps/extensions, Build Android apps for ChromeOS, configure build server

What I want to accomplish is configure a build server (like TeamCity) to build an Android application from source and convert it to a chrome extension that can be published on Chrome WebStore as an application.

First of all you can read this source which explains how to run android apps in chrome.

1. Download ARChon runtime and install it as an extenion in Chrome.

2. You can convert your apk manually with this chrome extension - Twerk

3. To enable Chrome App Launcher on Ubuntu (speeds up app launching) - follow this link.

4. Install chromeos-apk
asdsa

1. In a terminal, run the following command: sudo apt-get install npm
2. (Ubuntu only): Run the following command: sudo apt-get install lib32stdc++6
3. Download node.js.
4. Unzip the tar.gz file you downloaded from the above link.
5. Per the README file, open a terminal to the unzipped folder containing node.js. And run the following commands in order:
   1. ./configure
   2. make
   3. make install
6. Run the command: sudo npm install chromeos-apk -g
7. To make sure you're updated to the latest version (now or in the future), run: sudo npm install -g chromeos-apk@latest

5. Convert your compiled application in apk to chrome app with:

chromeos-apk --tablet --scale --name ApplicationName application.apk

5. Remember - to update the chromeos-apk plugin just run:

sudo npm install -g chromeos-apk@latest

Install CyanogenMod 11 on XPeria P running stock Android 4.1

1. First of all you need to unlock your bootloader. [worked]
Go developer_sony to proceed with unlocking (official SONY's website)

1. In your device, open the dialler and enter *#*#7378423#*#* to access the service menu.
2. Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

2. Then you need to root your XPeria P [worked]
The following root method worked for me:
DooMLoRD Easy Rooting Toolkit (v17)


3. To install CWM [worked]

CWM xda link
You need to have root access in order to use this method.
It worked fine for me.

CyanogenMod 11 did NOT install from CWM for me. It started fine and then couldn't read the phone model number properly.


4. To install TWRP [did not work as expected]

extract boot.img from cm-11-20141012-SNAPSHOT-M11-nypon.zip and copy it to the main script directory.

flash the boot image in fastboot mode with:
sudo fastboot flash boot boot.img


4. Cyanogemod 11 link

http://forum.xda-developers.com/xperia-u/p-development/rom-cyanogenmod-11-0-t2626639


Workaround:
After 1,2,4 (After flashing boot.img )
enter CWM and try to flash CyanogenMod. The device will restart and enter bootloop. Try pressing power button to enter TWRP.
Then flash cyanogenmod normally.
