[android-developers] Re: Whats the best practices when using Camera
You may want to surround the block with an if statement.
if(camera != null)
{
camera.stopPreview();
camera.release();
camera = null;
}

Greetings,
I have an application that uses the camera quite heavily. I often find
when I move between activities that the camera is quite liable to
crash throwing the camera service is unavailable.
I was wondering if their is a 'best practices' approach to using the
camera service. I'm sure I am doing something wrong. In my surface
destroyed method I usually have the following
public void surfaceDestroyed(SurfaceHolder holder) {
// TODO Auto-generated method stub
camera.stopPreview();
camera.release();
camera = null;
}
Thanks for any tips

[android-developers] Controlling Emulator with Hardware device?
Hi all, I had heard something in the Google I/O sessions about being able to now use hardware devices to control emulators (touching and possible picture taking, etc). Is this true? If so, has anyone found how to do it? Thanks! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Don't require rear facing camera?
First off, hi everyone. I didn't see this asked and I couldn't figure out how to word it to find it on the android dev site so I figured I'd ask you all. Basically, my company has an application right now that requires for a very specific function the rear-facing camera. This function isn't absolutely necessary. Now that more Android tablets are coming out without rear-facing cameras, our users aren't able to download the app onto their new devices. My question is, is there a way to somehow allow the user to download the app and maybe we could programmatically disable the function that needs the camera? We're using the basic camera permission in our Android manifest: android.permission.CAMERA. And we're running Android 2.2 (we won't be able to upgrade this any time soon). Any and all help is appreciated, thank you. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] disable log messages dataCallback(16, 0x11af10) when using mCamera.setPreviewCallback(this);
Im using Camera.setPreviewCallback method to retrieve all the camera frames on the onPreviewFrame on a 2.0.1 device. Im aware about the issue of GC interrupting on each frame on 2.2 platforms (http://code.google.com/p/android/issues/detail?id=2794) and I'm using the suggested work-around. However, there is also a log message dataCallback(16, 0x11af10) being print on logcat on each frame like this: ... D/Camera-JNI( 1795): dataCallback(16, 0x11af10) D/Camera-JNI( 1795): dataCallback(16, 0x11af10) D/Camera-JNI( 1795): dataCallback(16, 0x11af10) D/Camera-JNI( 1795): dataCallback(16, 0x11af10) ... These messages are very annoying because they make it harder to find my other log messages among them. My question is: Is it possible to disable the dataCallback(16, 0x11af10) log messages? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Working with the new ContactContracts API
Hello,
I have been working with contacts. I am able to show them, update but
when I want to delete any, it is not deleted completely. In Contacts
application is shown as (Unknown) without any data. What is more, I am
not able to delete it (only after I give this contact name). I have
tried to change deleted flag in RawContacts but it doesn't help -
contact is still displayed. Here is my example:
ArrayListContentProviderOperation ops = new
ArrayListContentProviderOperation();
ops.add(ContentProviderOperation.newDelete(Data.CONTENT_URI)
.withSelection(Data.CONTACT_ID + =?, new
String[]{1})
.build());
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
Should I do anything else to delete contact entirely?
Thanks,
Anna
