I am reading the phone number and other phone properties to send over a
socket using (sample code below)
try{
outputStream = clientSocket.getOutputStream() ;
objectOutputStream = new ObjectOutputStream(outputStream);
} catch (IOException e){
e.printStackTrace();
}
Server Code as
this.inClientSocket = inClientSocket ;
try {
inputObject = new ObjectInputStream(this.inClientSocket.getInputStream());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return ;
}
Questions
- I am running the client in debug mode. Why isn't the debugger showing me
where the problem is ?
- I put a breakpoint on the first time of the client code, still the client
hangs without the debugger reaching the breakpoint
Can someone advice me on what I am doing wrong.

[android-beginners] Re: Android app hangs, debug mode does not help, just hangs
I had associated the wrong application on the device with the
debugger.Previously I had com.mcruiseon.WelcomeScreen. I modified the code
to com.org.mcruiseon.client.WelcomeScreen. But the debugger on the emulator
was still debugging com.mcruiseon. Fixed that. But now I get the below.

[android-beginners] Re: VMWare Image of the Android Emulator
VMware emulates X86. Android emulator emulates arm. So.. no. You could make it worse by emulating a linux system running the android emulator though, that'd be funny.

If yes, it would prove very fruitful. Currently the emulator takes on a lot of processing power of the development machine. Making the development really painful experience. The more complex the product becomes the more difficult the development.

[android-beginners] getSystemService(Context.SENSOR_SERVICE) hangs emulator
Hi, The emulator seems to hang whenever I call getSystemService (Context.SENSOR_SERVICE). I've tried it with SDK 1,1 and SDK 1.5 but I always get the same issue. Any idea how to fix this?

[android-beginners] Re: getSystemService(Context.SENSOR_SERVICE) hangs emulator
Thanks for the quick reply. I thought it was possible to work with sensors on the emulator, as it looks like there's even a simulator for them (the openintents simulator)... How do they get to use the sensors on the emulator? On 3-Jul-09, at 5:43 PM, Mark Murphy wrote: jstoezel wrote: The emulator seems to hang whenever I call getSystemService (Context.SENSOR_SERVICE).

Back in Android 1.1 and previous, you could get the system service and things worked, insofar as you would not get any readings without OpenIntents' simulator. For whatever reason, Android 1.5's emulator no longer handles sensors at all. Unless a 1.5r3 is forthcoming, I suspect we will need to wait for the next major Android release (1.6? 2.0?). -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

Hi Mark, Are you saying that it should work with SDK 1.1? getSystemService hangs for both SDK 1.1 and 1.5 on my machine (Mac OS X).

Are you saying that it should work with SDK 1.1? getSystemService hangs for both SDK 1.1 and 1.5 on my machine (Mac OS X). Is it real Android 1.1 or Android 1.1 as supplied by the 1.5 SDK?

[android-beginners] Re: getSystemService(Context.SENSOR_SERVICE) hangs emulator
I'm using SDK 1.1, as provided with SDK 1.5. Given your symptoms, I am guessing that perhaps the sensor problem may stem from something in the qemu environment that the Android emulator runs in. Either that, or 1.1 was also broken, and I am mis-remembering. That's happened before (the mis-remembering part)... Can I still get the true SDK 1.1? http://developer.android.com/sdk/1.1_r1/index.html Just be sure that you get your hands on some hardware for real-world testing before you try shipping a product. Not only is there the Android version difference, but the sensor simulator still only gets you so far. There is no substitute for seeing how sensors behave in the real world on a real device. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: Garbage Collection of Threads
Thanks for all your help.
I've finally figured out the discrepancy. Using the following code, I
ran it through the debugger (in Eclipse, WinXP, emulator) and then ran
it just through the emulator - I get different results. The debugger
shows TestThread Running while the non-debugger version shows
TestThread FinaIizing. I believe the debugger holds a reference to
the TestThread which prevents it from getting garbage collected.
Of course, as you said this is all technically valid since System.gc()
is not guaranteed to do anything, but it's nice to know it won't have
any memory leaks on the final version.
package com.example.helloandroid;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
TextView mTV;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mTV = new TextView(this);
mTV.setText(Hello, Android);
setContentView(mTV);
TestThread t = new TestThread();
t.start();
try {
t.join();
} catch (InterruptedException e) {
e.printStackTrace();
}
t = null;
System.gc();
}
protected void finalize() throws Throwable {
super.finalize();
}
class TestThread extends Thread {
@Override
public void run() {
mTV.setText(TestThread Running);
}
protected void finalize() throws Throwable {
mTV.setText(TestThread Finalizing);
super.finalize();
}
}
}
