I am using `ant-release` to do a 1-step build of my Android app.

My build.properties looks like this:

    application.package=xxxxx
    key.store=sonr
    key.alias=sonr labs
    key.store.password=xxxx
    key.alias.password=xxxx

When I run ant-release everything is fine except for application signing. I get the error:


    -release-prompt-for-password:
    
    -release-nosign:
         [echo] No key.store and key.alias properties found in build.properties.
         [echo] Please sign /Users/syalam/Documents/git/joeborn-sonr/sonr/bin/SONR-release-unsigned.apk manually
         [echo] and run zipalign from the Android SDK tools.

I&#39;m trying to implement AQRecorder.h class from SpeakHere Apple Xcode project example, but even I rename my implementation class to ext. `*.mm` and put line with `#import &quot;AQRecorder.h&quot;` still getting error `&quot;Unknown type name &#39;class&#39;; did you mean &#39;Class&#39;?&quot;` and many others.
Which according to me means that it is not recognized as C++ class.

Any help will be appreciated.

to understand the `AIDL` in android, i want one real life example, means the at what scenario of development we need to use `AIDL`.

by reading the Android Docs  ... It puts me in confusion and so many question, so it is hard to read whole doc for me, can anyone help me

1. is it for communicating with outside the phone.

2. or to communicating with different apps, (why we need to communicate with other apps)

3. what kind of service they are talking in docs 


Example of AIDL use

I often need the different parts of my applications to have their own special behavior and UI, and I don&#39;t know how fragments can help. In most cases, I think it is quicker to create 2 different activities (e.g., 1 for tablets and 1 for handsets), and to share the common behaviors and events in a third class.

So, keeping this in mind, why should I use fragments ?


When and why should I use fragments in Android applications?

The code for drawing an arrow with *Style: Fill* is given below: 

    paint.setColor(Color.parseColor(&quot;#bdc0dc&quot;));
    paint.setStyle(Style.FILL);
    canvas.drawPath(arrowPath, paint);
    paint.setColor(Color.BLACK);
    paint.setStyle(Style.STROKE);
    paint.setStrokeWidth(2);
    canvas.drawPath(arrowPath, paint);

And the output I obtain is this : 

![enter image description here][1]

Now what I want do is set style to Gradient(Style.gradient not present in android...) to obtain the arrow similar to the image given below : 

![enter image description here][2]

How do i do it ? I tried adding style in style.xml but was unable to add gradient there as it accepts item as parameter..

Does anyone know how can you get the context of the **Test project** in Android junit test case (extends AndroidTestCase). 

Note: The test is NOT instrumentation test.

Note 2: I need the context of the test project, not the context of the actual application that is tested.


I need this to load some files from assets from the test project.

Are the exported private keys gotten by executing `gpg --export-secret-keys` still encrypted and protected by their passphrase? This seems to be the case but I can&#39;t find anywhere that explicitly confirms this.

If the exported keys are still encrypted then is there anyway to get the pure, unencrypted private key (like you can for the public segment)?

I have two SQL Servers (both 2005 version).

I want to migrate several tables from one to another.

I have tried:

* On source server I have right clicked on the database, selected `Tasks/Generate scripts`.
The problem is that under `Table/View options` there is no `Script data` option.

* Then I used `Script Table As/Create script` to generate SQL files in order to create the tables on my destination server. But I still need all the data.

Then I tried using:

    SELECT * 
    INTO [destination server].[destination database].[dbo].[destination table] 
    FROM [source server].[source database].[dbo].[source table]

But I get the error:

&gt; Object contains more than the maximum number of prefixes. Maximum is
&gt; 2.

Can someone please point me to the right solution to my problem?

I want to export all collections in MongoDB by the command:  

    mongoexport -d dbname -o Mongo.json

However, why doesn&#39;t this work?

How do I test an update of my application, versus a clean install? I see that `adb install` has several flags, but I&#39;m not sure which one mimics reality.

I explicitly need to test app updating.



Testing an adb update, versus install?

I know that `adb install` will not replace an existing package if it&#39;s of a different build *type* (i.e. debug vs. release).

Eclipse also successfully replaces the debug apks whenever I run a debug session.

But when I attempt `adb install` for replacing an existing *release* apk with another release apk (same package name!), I get a failure message:

    adb install myapp-release.apk 
    	pkg: /data/local/tmp/myapp-release.apk
    Failure [INSTALL_FAILED_ALREADY_EXISTS]
    745 KB/s (34310 bytes in 0.044s)

Wasn&#39;t that supposed to work? What am I missing?

I want to install an APK from PC to Android device. And because of user&#39;s Android and generally technical skills, I need to do it as automatically (silently) as possible. So how do I send an APK from PC to Android and start install there?

What is the equivalent of `apk` in `iOS`?

What is the equivalent of apk in iOS?

I&#39;ve decoded an APK with apktool (as the original source code was lost) so I could fix some issues with the layout xml files. I&#39;ve then rebuilt it back up with apktool and when I tried to install it on my device (using adb: adb install appname.apk) it gave me this error:

    [INSTALL_PARSE_FAILED_NO_CERTIFICATES]

the original apk however was signed by a keystore (on eclipse IDE), this one isn&#39;t, how can I sign it properly with it&#39;s original keystone file outside Eclipse!?

Does this code always evaluate to false? Both variables are two&#39;s complement signed ints.

    ~x + ~y == ~(x + y)

I feel like there should be some number that satisfies the conditions. I tried testing the numbers between `-5000` and `5000` but never achieved equality. Is there a way to set up an equation to find the solutions to the condition? 

Will swapping one for the other cause an insidious bug in my program?



~x + ~y == ~(x + y) is always false?

At my code, I do not use int or unsigned int. I only use size_t or ssize_t  for portable. For example:

    typedef size_t intc;    // (instead of unsigned int)
    typedef ssize_t uintc;  // (instead of int)

Because `strlen`, `string`, `vector`... all use `size_t`, so I usually use `size_t`. And I only use `ssize_t` when it may be negative.

But I find that:
&gt;    The unsigned integer types are ideal for uses that treat storage as a bit array. 
    Using an unsigned instead of an int to gain one more bit to represent positive integers is almost never a good idea. 
    Attempts to ensure that some values are positive by declaring variables unsigned will typically be defeated by the implicit conversion rules.

in the book [The C++ Programming Language](http://www.amazon.com/dp/0321563840).

So I am puzzled. Am I wrong? Why does the STL not abide by the suggest on the book?


should use size_t or ssize_t

Let&#39;s say I have this number `i = -6884376`.
How do I refer to it as to an unsigned variable?
Something like `(unsigned long)i` in C.

How to convert signed to unsigned integer in python

I have a [little VM for a programming language](https://github.com/munificent/wren) implemented in C. It supports being compiled under both 32-bit and 64-bit architectures as well as both C and C++.

I&#39;m trying to make it compile cleanly with as many warnings enabled as possible. When I turn on `CLANG_WARN_IMPLICIT_SIGN_CONVERSION`, I get a cascade of new warnings.

I&#39;d like to have a good strategy for when to use `int` versus either explicitly unsigned types, and/or explicitly sized ones. So far, I&#39;m having trouble deciding what that strategy should be.

It&#39;s certainly true that mixing them—using mostly `int` for things like local variables and parameters and using narrower types for fields in structs—causes lots of implicit conversion problems.

I do like using more specifically sized types for struct fields because I like the idea of explicitly controlling memory usage for objects in the heap. Also, for hash tables, I rely on unsigned overflow when hashing, so it&#39;s nice if the hash table&#39;s size is stored as `uint32_t`.

But, if I try to use more specific types *everywhere*, I find myself in a maze of twisty casts everywhere.

What do other C projects do?




When should I just use &quot;int&quot; versus more sign-specific or size-specific types?

I have below a simple program:

    #include &lt;stdio.h&gt;
    
    #define INT32_MIN        (-0x80000000)
    
    int main(void) 
    {
    	long long bal = 0;
    	
    	if(bal &lt; INT32_MIN )
    	{
    		printf(&quot;Failed!!!&quot;);
    	}
    	else
    	{
    		printf(&quot;Success!!!&quot;);
    	}
    	return 0;
    }

The condition `if(bal &lt; INT32_MIN )` is always true. How is it possible?

It works fine if I change the macro to:

    #define INT32_MIN        (-2147483648L)

Can anyone point out the issue?
