[android-beginners] Re: using an API not in the SDK
There is no procedure; whatever means you find to achieve this would break
when the system is updated over the air with changes that modify/remove the
non-public API
(and believe me, internal changes between releases are *very* numerous).
Then your users will start to hate you and give you 1-star ratings, etc...

Hello,
I'm trying to write my first android application which executes
commands I feed to it on the comandline. I looked through the public
git repository and found android.os.exec which should meet my needs
fine, however I noticed that it isn't part of the SDK. When I try to
add the class to my project and call it via createsubprocess(), it
compiles fine but i get a force close as soon as it tries to run on
the emulator or my device. According to the ddms logs, its getting
stuck at an unsatisfied link error. Below are the three files in my
project... if anyone could help me out, it would be much appreciated

[android-beginners] What's the correct way to switch off the emulator?
All, I always close the emulator window to switch off but sometimes I found emulator process is still hanging there which will get me some error when I launch another new process.

[android-beginners] Connecting via USB - how to use a computer's internet rather than wifi
Hi, Just curious if I am able to use a computer's Internet connection whilst connected via USB. There is no wireless network, so my only option is to connect the phone to the computer to obtain a connection. If it is possible, my second question is: If I were to connect like this, how might I address a webserver running on the computer? Using the emulator I would connect via 10.0.2.2, but obviously this won't work once running on the phone, as the address is not correct for the usb - pc connection. I hope this makes sense!

[android-beginners] Re: How do I set the value of an EditText
That's what I thought too but I crash the task every time the activity that contains this code is started: EditText userText = (EditText) findViewById(R.id.userText); userText.setText(userParam); This is the basic way I thought to have the value set but it crashes every time.

[android-beginners] Re: Display Icons
Each activity with intent-filter action android:name=android.intent.action.MAIN / category android:name=android.intent.category.LAUNCHER / /intent-filter in your AndroidManifest.xml will show up in the launcher. So if you want to see only one icon for one activity in the launcher, then only that one activity should have the quoted intent filter set. -- http://www.deepdroid.com On Mar 20, 12:09 am, moblmojo grantk...@hotmail.com wrote: How do you get only one icon to display in the main menu? All of my .java files have their own separate icon in the main menu. Is this because of the activity or the .java file, or what? They all use the same icon, although I have only specified it in the main application activity. Users can click a different icon and get into the activity without going through the main application menu.
