As we know, when we connect the G1 phone with USB, we could use "adb devices" to show its device name. My question is whether there is a method to detect this device name in phone with code, or how to judge the "device name" is the just "myself" with code?

I have a timer that schedule a task to run every 5 minutes. This task send a request to a server, so I need to be sure that CPU is on so that wifi or 3g can be used.
So the first thing I do in my run() method is :
CODE:.........
And the last thing I do in the run() is : wl.release() ;
I would like not to release here to be sure my service will run in the next 5 minutes :
The question is : if the device is already in a sleep state, can I wake up it with my wl.acquire() ?
I posted this back in May on the [android-developers] Google Group. I never heard back and was not able to reproduce the problem until one of my students did last week. I figured I'd post it here and see if it rang any bells for anyone.
In one of my code samples, I have the following method:
CODE:..............
When I run it, sporadically, I get this:
CODE:......................
This makes no sense to me. The database is definitely open. The SQLiteClosable is the SQLiteQuery created by SQLiteQueryDriver, and I see no evidence that there is an object pool or something going on here that might explain how a "new" SQLiteClosable is already closed. The fact that it is sporadic (meaning the same UI operations sometimes trigger the exception, but not always) suggests some sort of pool, race condition, or something...but I'm not sure where.
The code in question is from the LunchList tutorials out of my Android Programming Tutorials book. It's a bit spread out and not terribly suitable for posting directly in SO. You can download the code for that book from the above link if you want to take a look at it. I do not recall exactly which edition of the tutorial the student was working on at the time, though it was in the Tutorial 12-Tutorial 16 range. I was mostly hoping to run across somebody who had tripped over this problem before and had a likely culprit. I'm fairly certain my database is open.
I have an application with notification. I want my notification can wake the device up when it goes off but the device is asleep. Could anybody tell me how to do by some code?

The application My App (process com.mycompany.android) has

When integrating AdMob ads into your application it is recommended to use test mode. In test mode test, ads are always returned. Test mode is enabled on a per-device basis. To enable test mode for a device, first request an ad, then look in LogCat for a line like the following:
To get test ads on the emulator use AdManager.setTestDevices...Once you have the device ID you can enable test mode by calling AdManager.setTestDevices:

Is there a way to check if our code is running in the emulator vs a real device? I'm using a Map View which requires a signing key. I'm using the signature of the eclipse debug key when running on the emulator, but this won't work when I build a release version. I think I need to have a check to see if I'm running on a real device, and set it to the real release key at that time.

View 4 Replies View RelatedWhen user press log off button following 2 lines should happen:
stopService(myIntent);
unbindService(mConnection);
myIntent is same intent that was used to start service(desperate attempt to get this working). mConnection is basically straight from android's development center.
I have verified that service's onDestroy gets called. There it sets boolean variable true to make Runnable stop it's course(which among itself starts up gps tracking if certain requirements happen), calls the locationManager's removeCallbacks and finally calls super.onDestroy function.
I thought this was supposed to be enough to stop the service from running and acquiring GPS positions(and likely sends them to server too) but the GPS acquiring symbol is STILL blinking. I presume this is not just graphical error by the phone but that it still is searching(and wasting battery).
What have I done incorrectly? What else I need to do to get the service stop when I want? Service dying off when android decides off yet staying up when I'm trying to get it closed.
I would like to measure the code coverage for the UI application without using JUnit test cases. Is there any way that we can capture the report for the user key events on the application which is running on device.

I have tried to root this phone using Gingerbreak, Revolutionary, Z4root, and a few others. When I search on Google or the XDA website I can't find absolutely anything about an HTC Acquire. It's like the internet thinks the phone doesn't exist? I recently upgraded to it from my HTC Desire CDMA Bravo-c that I had rooted, flashed a custom rom, custom kernel, custom radio, the works.
With a free sunday at my disposal, i thought i would try and sort my hero out as it has become super-laggy after the OTA 2.1 update (HTC hero locked to 3UK network, previously had 1.5).
So i've been trying to read as much as i can on this and other forums and got as far as installing Universal Androot, which reported success in rooting the phone.
However have now installed (and bought PRO ver) of Titanium Backup which refuses to recognize the root. It returns:
ERROR: Sorry, I could not acquire root privileges. This application will *not* work! Please verify that your ROM is rooted and includes BusyBox, and try again.
Yet, TB is listed as 'allowed' under SuperUser Permissions. And even weirder when the error dialogue box comes up sometimes a strapline flashes briefly across the screen 'Titanium backup has been granted .. permissions'. I take it that this is Superuser informing me.
So why doesn't Titanium recognize the root? Have tried re-starting and rerunning Androot (which reports that phone is already rooted, do you still wish to proceed). It's almost as if superuser isn't giving the OK fast enough or something.
Obviously don't want to start messing around with ROMs if i can't first backup my data!
I followed evilisto's guide to make honeycomb style lockscreen.I could get the framework layout working, but since I didn't know how to get java source code for my device, so I just decompiled framework2.jar and modified MultiWaveView.smali(since framework.jar doesn't have this file, I had to decompile framework2.jar), compiled and odexed it.But the radious of chevron is too big and animation speed didn't change.What should I modify to change animation speed and radious of chevron?
I changed the values to extremely high value, but it seems framework2.jar and odex doesn't work for lockscreen chevron at all..

What driver am I missing? I read that there should be four. One for adb? I have even tried selecting the adb driver and it still only installs the three. I build computers for a living and can not for the life of me figure this out.

View 7 Replies View RelatedCan someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? device is connected over bluetooth - how are devices identified in this case? device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network?
