I am trying to understand threads and how they work, and when, etc. I expected the pid in LogCat to be different in the background thread logs but the pid is always the same. Is the pid something other than the thread ID? If it is, is there a way to indicate the thread ID in LogCat?

How can I implement a run() method of thread if I create a Thread Global?
I mean If I create a Thread Globally then can I implement its run() method {" public void run()"} anywhere in my Application?
In the run() method I have to write the code to perform some action.
IF I can do it then please can anyone show me briefly how to do it particularly.
I am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.
The requirement is like this.
An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .
All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.
So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).
How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.
I have a separate thread running to get data from the internet. After that, I would like to update the ListView in the main thread by calling adapter.notifyDataSetChanged(). But it does not work. Any workaround for that?

View 2 Replies View RelatedHere's a snip that successfully reads off, to Eclipse LogCat, the height and width of the .PNG on the SD card:
import android.app.Activity; import android.os.Bundle;
import android.util.Log; import android.graphics.Bitmap;
import android.graphics.BitmapFactory; import android.os.Environment;
//...
Bitmap bmp = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory().getAbsolutePath() + "/sample.png");
int width = bmp.getWidth(); int height = bmp.getHeight();
int[] pix = new int[width * height]; bmp.getPixels(pix, 0, width, 0, 0, width, height);
int R, G, B; for (int y = 0; y < height; y++){ for (int x = 0; x < width; x++) { int index = y * width + x;
R = (pix[index] >> 16) & 0xff; //bitwise shifting G = (pix[index] >> 8) & 0xff; B = pix[index] & 0xff;
// [This is where I'd put it. But I can't get a red line off the editor when I do anything.] } } Log.v(TAG, width + " " + height);
I can't for the life of me use Log.v() to report the value of R or G or B. Everything I'm doing draws a red line under v or something when I try. I've tried toString() and everything.

I have Logcat on my android phone, but the process of getting the messages to somewhere readable isn't smooth at all. Can someone tell me how to get Logcat running on the emulator? Is there anything I can do to see debug messages other then having to copy the apk to my phone and testing it?

View 4 Replies View RelatedUsually I can see the exceptions that are thrown in my application via adb logcat. But they seem to get lost when thrown by code running in a somehow different Thread. I use the Smack Library to receive XMPPMessages. When the receiving thread throws a NullPointerException that is not logged. I can catch it myself and log it with android.util.Log. Is it possible to have logcat show all stacktraces from all exceptions thrown in all Threads?

View 13 Replies View RelatedI am trying to figure out why my app forces close immediately on a nexus one (recurring comment which is dragging my rating down). Ironically, I heard a rumor that if I had just a half star more (up to 3.5 from 3), I would qualify to get a free nexus one from google. If anybody has a nexus one and can connect it up to get the logcat dump of the stack trace of the error. You can find my app by searching for "Compass Ball" on the market.

View 3 Replies View RelatedSince getting Eclipse to recognize and debug both the emulator and a usb connected device I have been unable to see any of my embedded Log.x messages appear in LogCat log. I do though still see real time system messages appear in the log. Log.x was originally working when all the debugger would recognize was the emulator. I had to tweak a number of profile and project settings to get debug to work with the device and may have inadvertently toggled something having to do with LogCat. But I don't see anything that sticks out in the menu's as possibly causing the log problem.
View 5 Replies View RelatedIs there a way to make LogCat's output to appear in Console view in Eclipse? LogCat view is much less convenient that Console, because it's hard to see long messages in it (they are trimmed by column border) and there are no clickable highlighting in exception stack traces to quickly navigate to source of error. Just to make clear - I'd like to have clickable stacktraces, like the ones in normal Eclipse console so I can quickly navigate to the source of error.

View 3 Replies View RelatedAfter installing Android 1.5 on my ADP I can't check logcat directly from the phone.
When running 'su', in terminal, I get 'uid XXXXX not allowed to su'. 'logcat' gives permission denied /dev/log/main.
If I get an exception/force close in any of my apps I'd like to be able to check the stack trace/logs without having to connect it to a computer. I guess it could be possible to check any created traces.txt files later.
I know I can check logcat with adb logcat, or adb root shell, logcat. Is there a way of checking logcat directly from the phone?
When i run my program, logcat shows a lot of activity with GC like.

How can I empty the logcat buffer in Android? I use adb logcat from command line and pipe the output to a file, since the DDMS has a very limited buffer. At the moment, when I restart my app (after fixing bugs etc) the logcat buffer has data from the previous launch as well. Even uninstalling the app does not clear the buffer. The only way I've found so far to clear the buffer, is reboot. This is effective, but would like to know if there's an easier way.
