I run some DB stuff inside an asynctask that runs inside a runnable via handler.postdelayed(r, 30000). It gets repeated (as you can see, every 30 seconds).
Sometimes, not everytime, my app is crashing. Below is the logcat.

You get somewhere along the logcat an IllegalStateException because the database is already closed. Make sure your background tasks are canceled before you close the database, which is done latest in onDestroy of your Activity.

Are you sure you did not close a Cursor by accident before usage. That or is the asynctask by any chance started twice at some point?
Whatever the reason is, it seems the code at some point is trying to access a closed Cursor.

1)Followed all the requirements in Facebook's Getting Started post.
2)Added the meta-data to the XML.
3)Added the key-hash to facebook
If you see any particular files that might be causing the problem and want to see it before answering, do let me know.
All,
I am using the CWAC-Camera-v9 library in my application.
I am seeing a blank screen while the camera launched and the application crashes while taking picture with below error message.

Any pointers will be really helpful.
EDIT
The test device is Samsung Galaxy S3 GT-I9300. The camera in the native application works fine.
What i am trying to do is to use the camera library in a cross-platform tool called Kony. Kony compiles and integrates the library without any issues. But while launching the camera, i am seeing this issue.
May i know the probable conditions at which the Camera fails to load.
I am trying to launch the MainActivity in the CameraDemo-V9 sample as below
Intent myIntent = new Intent(CamTestActivity.this, com.commonsware.cwac.camera.acl.demo.MainActivity.class);
this.startActivity(myIntent);
This sample is working expected in a Android native project.

Thanks,

In terms of the exception, you are taking a picture before the preview has been set up, based upon the error message.
In terms of the black screen, off the top of my head I do not know what might cause that. Try running one of the demo apps and see if it behaves properly. If it does not, there may be some incompatibility between the library and your device, in which case I would need to know the specifics of what device you have. If the demo app works, presumably there is something that you are missing in the setup, and so you might compare your code with that of the demo app.
I am developing an Android native extension for push notification. I have added the gcm library to the class path but the class GoogleCloudMessaging could not be found. Even thought the jar from google is added to the class path of the android project, I still get the error message, so after I export the jar I am updating with the classes from the Google gcm jar. After this everything looks ok at jar level but the problem still persist and I have the following error:

I have two activities that both make different http requests to my server when started.
When I switch back and forth between them the responses start to have some delay because they get queued up on top of eachother.
I would like to empty and abort this connections and just keep the latest one.
I tried
httpClient.getConnectionManager().shutdown();
but it throws

You have an array out of bound in com.prologica.procamera.MainActivity UploadPhotos.SendFolders(MainActivity.java:127). Check line 127 in MainActivity to make sure you are not going out of bounds. According to the log, the length is 5 and you are trying to access index 5(which does not exist)
