阅读更多关于 How to get camera result as a uri in data folder?

I am creating an application in which I want to capture a image and then I want to send that image in the email as a attachment. I am opening a camera using android.provider.MediaStore.ACTION_IMAGE_CAPTURE intent action and I am passing the Uri of the file as a parameter EXTRA_OUTPUT to get the image back to the file. This is working perfectly and I am able to get the captured image if I use the external storage uri as a EXTRA_OUTPUT but if I use the data folder uri it is not working and the camera is not closing and its all buttons are not working. Here is my code for get the result in the

问题 How can we ensure that certain applications are not able to access my data stored in content provider where in certain other applications can access that? Basically I need to allow some application of my interest to access my data stored in Content Provider but I do not want all the applications to be able to access that data. How can I achieve this? Thanks. 回答1: The easiest way is to protect the content provider with a permission you define. Make it a signature a permission so only apps

How to implement a ContentObserver for call logs

阅读更多关于 How to implement a ContentObserver for call logs

问题 I\'d like to know if there is a way to know if the content provider of callings has changed. I mean, if I make a call, or I answer a call, it returns a \"flag\" that a new log has been added to the call log, or the place where Android store informations about callings. Because, when I make a call, Android stores the number, the contact name (if exists), the hour of the calling, the duration, ..., all in the content provider. So is there a way to capture this \"flag\" that says the content

问题 I understand that Content Providers are made to allow publicly sharing data between applications.

Specifically, I\'ve been reading through the NotePad example from the sdk\'s samples directory. Now, I can see that SQLiteOpenHelper has a close() method. I\'m aware that leaving idle databases open is bad practice and can cause memory leaks and whatnot (unless this discussion is headed in the right direction). If I were using
