When I check the file written, it's always stuck when it writes till 4576byte. (Original image size is over 150k)

View 3 Replies View RelatedI write a app but it is not doing anything..
code is given below:
CODE:..............................
I have two published apps that are pretty targeted to the user collecting their personal medical data (like Blood Pressure, etc.) and then, eventually sending it somewhere, if they choose.
I decided to put Read/Write permission on my ContentProvider, so if another app comes along that wants to the access that content, the user will be warned. The permission that is required is declared in my apps.
When the user installs my apps, they are also given a warning that the app requires that permission (even though it's the one that declares it), and it shows up in the Marketplace also.
The question is: Is it possible that the permission acceptance part of installing my app could be putting customers off? I don't know what other's acceptance rate is, but mine is around 50% of customers who download it have active installs.
How can I write a Broadcast Receiver that will be invoked when user clicks on any application icon?

BackGround: There are Facebook APIs(and SDKs) available to develop applications for other Mobile devices like iPhone, BlackBerry etc, but it seems there are no official ones for Android(?).
People have ported Java APIs to work on Android and have written FaceBook Client applications(FaceBook dev: Wiki Page). Apparently, there is also a light weight FaceBook SDK in alpha release for Android(a la FBRocket). But it is not avised to be used in Production.
Since these FaceBook functionalities have been exposed as REST based service, most of work would invove sending requests in desired format over Http. So, writing a FaceBook client app for Android certainly is doable.There are similar applications already in market e.g.: Bloo.
Questions: When asked to write a FaceBook client application what approach should one undertake? Should we choose the SDK or invoke the services over Http?
If there is already a Web application that integrates with FaceBook, can we just browse to that Application from inside a WebView and be done with this?

View 4 Replies View RelatedSorry for the ambiguous title but I'm doing the following to write a simple string to a file:
try {
File root = Environment.getExternalStorageDirectory();
if (root.canWrite()){
System.out.println("Can write.");
File def_file = new File(root, "default.txt");
FileWriter fw = new FileWriter(def_file);
BufferedWriter out = new BufferedWriter(fw);

out.write(defbuf);
out.flush();
out.close();

else
System.out.println("Can't write.");
}catch (IOException e) {

}
But root.canWrite() seems to be returning false everytime. I am not running this off of an emulator, I have my android Eris plugged into my computer via USB and running the app off of my phone via Eclipse. Is there a way of giving my app permission so this doesn't happen? Also, this code seems to be create the file default.txt but what if it already exists, will it ignore the creation and just open it to write or do I have to catch something like FileAlreadyExists(if such an exception exists) which then just opens it and writes?

View 3 Replies View RelatedCurrent I just use Android 1.6 emulator. I am writing a simple code which needs write one result file to SD card. But It is failed to open one file to write (Reading is ok). I tried to use C level API and Java level API but both of them are failed. Furthermore, I tried to use chmod comand in the shell but it is still useless. It is known in the Android 1.5 or befor, it should be OK. Is it a new feature of 1.6 or it is just my emulator's issue? If it is a new feature, can someone figure out how to write the data into SD card?
