Android :: Code When Rotate The Device
Feb 2, 2010
I am getting error when I rotate the device (it was HTC with Verizon):
The application My App (process com.mycompany.android) has
stopped unexpectadly. Please try again.
So, I think I need to code for this issue. In order words, when rotate the device from landscape to portable or from portable to landscape, application needs to catch this event.
Is it right ?
How to make it ? What is wrong here ?
Is it possible to test on the emulator ?

There are some shortcoming for system's rotate screen function:
1. It is too sensitive to result in many unwanted rotating actions.
2. Accelerometer consumed power greatly. I want disable it and control screen orientation by my own program. Is it possible?

As we know, we can rotate a bitmap through 2 ways. The 1st way is: Matrix mt = new Matrix(); mt. postRotate (degree);Bitmap bitmap = CreateBitmap(src, 0, 0, w, h, mt, true); canvs.drawBitmap(bitmap, 0, 0, paint); In this way, we always need create new bitmap for every rotation, it is not good way for high performance game or app.The 2nd way is: canvas.save(); canvas.rotate(degree); canvas.drawBitmap(bitmap, 0, 0, paint); canvas.restore();In this way, we avoid creating new bitmap frequently, but the rotation bitmap is distortion, the bitmap quality is worse than first way.So, Is there 3rd way to rotate bitmap with high performance and good quality? Your any comments are really appreciated!

I just bought the Nexus One unlocked for AT&T and really like it. 1 wierd thing is that when I rotate the phone counter clockwise, the screen goes to landscape just fine; but when I rotate it clockwise it does not go to landscape "the other way". And, if I'm holding the phone 'normally' and rotate it 180 degrees ('upside down') it doesn't follow.My youngest daughter delights in telling me that her iPhone does this with no problem. What's up with that?

I have a HTC Magic (Rogers Canada).And, I see how the Dream (G1) rotates the home screen. can the Magic do that as well? Also, anybody know if it's possible to rotate the screen to the right and not just to the left? Shouldn't the acceleromater detect all the different rotated modes (even upside down?). that'd be cool

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?

Admob code cant see on device.
I followed the instructions here: http://www.admob.com/docs/AdMob_Android_SDK_Instructions.pdf everything ok, but the 6. not clear for me
"Step 6
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.

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..

I am getting the "Code: 10 - This device can not start" issue.
Running XP SP3
Looking at the device manager I see the following drivers installed under:
USB Controllers>
Samsung USB Composite Device>
-
sscdbus.sys
sscdwh.sys
sscdwhnt.sys
-
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.

I have a brand new Nexus One. I'm trying to follow the directions for installing the USB driver. When I plug in the device, it doesn't start the New Hardware Wizard, as the documentation suggests. I can run hdwwiz.exe to launch it and manually install the driver, but when I do, Device Manager says: "This device cannot start. (Code 10)"
