Simran Dev Simran's place

G+ Messenger! Back to work!

Update* Jan 1 2012

An update from this Project is that I found out that Google doesn't use XMPP for the chatting, but only for authentication. I did some stuff to the Google+ *cough* apk, and saw some interesting code. They have implementations of their project "protobuf", and some private client called "Bunch". Also if you guys don't know yet, Huddle will be available for devices other than Android or iOS through SMS. Google you fail when you know that XMPP already a Group Chat. Oh well, what ever the reasons are the project continues, and will be out as soon as possible.

Initial description* Dec 31 2011

Awhile ago I had posted a thread asking for help and stopped development of this project. I decided to finish this and start all over. I had some help from a another friend coder and RustyGrom as well for his finding of his XMPP string. I'm coding this in C# and I'm writing the client from scratch, no libraries or anything. Here's my current progress and picture of the testing client:

Launch apps from ADB/Terminal

For all of you that code apps on PC that use ADB, if you ever wanted to launch an app from ADB or Terminal, here's a small tutorial.

Please note that this method can be used in any programming language that has the control to run commands from ADB, Terminal, or the shell itself. I won't be posting any code, but I will be posting the commands needed to do so.

Lets dissect the command first:
am start -n com.package.name/com.package.name.ActivityName

Basically we get the package and Activity name. Let's say we are going to open the "Settings" app, our command should look like:

Using ADB:

adb shell am start -n com.android.settings/.Settings


Using Terminal/Shell:

am start -n com.android.settings/.Settings


With the package name being: "com.android.settings" and the Activity name being: ".Settings". If you're familiar with a little bit of Android Developing this should be easy, if not Google it.

If you want to be more specific with your command then you can use intents to query something more specific. The extra in the code "-a com.example.ACTION_NAME", therefore our command looking like:

Using ADB:

adb shell am start -a com.example.ACTION_NAME -n com.package.name/com.package.name.ActivityName


Using Terminal/Shell:

am start -a com.example.ACTION_NAME -n com.package.name/com.package.name.ActivityName


But I'm going to be going into that today.

If all is done correctly then your device should open the requested app and activity properly. If not, experiment with it.

For those who don't know how to use ADB in .NET, Google it, or here are some simple instructions to do so:
1. Initialize a new process which is the "adb.exe"
2. Send commands to it like a console window
3. Read the output

Flash zip files from ADB/Terminal (And other commands)

I For all of you that code apps on PC that use ADB, if you ever wanted to flash a zip file from your app using the recovery it's quite simple. You've seem ROM Manager do it, now why can't you?

Please note that this method can be used in any programming language that has the control to run commands from ADB, Terminal, or the shell itself. I won't be posting any code, but I will be posting the commands needed to do so.

I use ClockWork Recovery on my Android device(Works with AmonRA too). We first need to set the recovery to read commands and not just boot normally.

Using ADB:

adb shell "echo 'boot-recovery ' > /cache/recovery/command"

Using Terminal/Shell:

echo 'boot-recovery ' > /cache/recovery/command


Next we need to set our command, Here's a list of commands supported by several recoveries(Open-Source ftw!):

* --send_intent=anystring - write the text out to recovery.intent
* --update_package=path - verify install an OTA package file
* --wipe_data - erase user data (and cache), then reboot
* --wipe_cache - wipe cache (but not user data), then reboot
* --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

We'll be using the "update_package" at this time, but feel free to try the others. Now basically the syntax for our "update_package" is "--update_package=PARTITION:NAME.zip", most likely the package will be on the SD Card and for now I'll use the name "update.zip" for the package, so now it looks like "--update_package=SDCARD:update.zip".

Now how do we set/write that command to the recovery?

Using ADB:

adb shell "echo '--update_package=SDCARD:update.zip' >> /cache/recovery/command"


Using Terminal/Shell:

echo '--update_package=SDCARD:update.zip' >> /cache/recovery/command


Now that we have set/written the command for the recovery we now lastly reboot into the recovery:

Using ADB:

adb shell "reboot recovery"

Using Terminal/Shell:

reboot recovery


If all is done correctly then your device should reboot into the recovery and immediately try to flash the zip file. Any errors will be printed during the process, and if any errors within the recovery should be printed on your device screen.

For those who don't know how to use ADB in .NET, Google it, or here are some simple instructions to do so:
1. Initialize a new process which is the "adb.exe"
2. Send commands to it like a console window
3. Read the output

Android 4.0 Ice Cream Sandwich Source code Released!

Today is a good Monday due to the fact of Google releases the Source code for Android 4.0 Ice Cream Sandwich. I hope to see some decent ROM's out, especially from the CyanogenMod team(CM9). The link as to how to get the Source code is at the bottom of this post. Please note that you may not be able to build the code due to Google not finished syncing the code to the server, so be patient!
