Re: [android-developers] Re: Compression of files kept in Assets folder and in res\raw folder.
This sounds something I need. I will try the same and update the thread.
Thanks Leonid.

Hi,
According to 'unzip -v' command for my own apk file, the zip-file is

76% of the file is the compression ratio.
Use built-in java Zip* classes to access your contents inside APK if
you don't want to use AssetManager:

Re: [android-developers] Re: Compression of files kept in Assets folder and in res\raw folder.
Sure, you can access your entire apk from within NDK and native code, but
it'll be a little bit harder than from java.
1. You need to include libzip into your project and compile it together
with your own C++ code.
2. Pass the full path to your apk file from Java to C++ method
3. Open APK with libzip call and the given path.
4. Read contents using libzip.
See this link to explanation and examples of code:

Hi,
The questions I have is:

2) Are the files kept in "res/raw" folder compressed when apk is
zipped.
Lets say if the answer to the questions is Yes, ie, the files are
compressed.
1) Does this mean that AssetManager does the decompression and then
gives us the istream?
2) Lets assume that I don't go through the AssetManager and read the
file directly by accessing the apk path and the offset (The FileDescriptor
method). If the file was compressed, the bytes I will read after doing an
fopen() will not make sense to me, right?

Re: [android-developers] Re: Compression of files kept in Assets folder and in res\raw folder.
Thanks for the reply Leonid. This is close to what I am looking for.
What is problem is that I want to access the file from the native code.
>From the java code, I would have used the asset manager itself.
These are my requirements:
1) I want to access the file through the native code.
2) preferably I want a file handle. And not buffer(like assetmanger gives)
Is there's a similar utility provided by the ndk?
Thanks

[android-developers] How to inject mock objects in Android?
Hi,
I am facing issue while unit testing :
// Service class that have to be tested.
class FooService extends Service{
public static FooService sFooService;
private Bar mBar = new Bar();
//Other private objects
@Override
protected void onCreate()
{
sFooService = this;
}
public static FooService getInstance()
{
return sFooService;
}
@Override
protected void onDestroy()
{
sFooService = null;
}
public void doSomething()
{
//do Some stuff here
if(done)
{
mBar.perfomAction(true);
// Now this performAction method doing many stuffs using some other
classes
// that may have dependency and initialized from some else. Hence
throwing exceptions.
// Therefore need to mock Bar class. but how ??
}
else
{
mBar.perfomAction(false);
}
}}
// Test Class
class FooTest extends ServiceTestCase{
protected void setUp() throws Exception
{
super.setUp();
MockitoAnnotations.initMocks(this);
startService(new Intent(getContext(), FooService.class));
}
protected void tearDown() throws Exception
{
super.tearDown();
}
public void testdoSomething()
{
Bar bar = mock(bar.class);
doThrow(new RuntimeException re).when(bar).performAction(true);
//How to inject bar mocked object?
assertNotNull(FooService.getInstance());
try
{
FooService.getInstance().doSomeThing();
Assert.Fail("Runtime exception should be thrown");
}
catch (RuntimeException re)
{
}
}}
Now, here how can I inject bar mocked object which is created using Mockito
?
I have googled this, and found that some guys suggested to create getter
and setter for Bar class. Which I don't think is a valid solution, because
there could be number of private object, that will be visible to outside
FooService class.
Regards,
Yuvi
