This [site][1] 
 helped me a lot to properly sign the unsigned apk. But,for the last process i.e. for `jarsigner`,following command need to be used
    
    jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore    my_application.apk alias_name.

Further do look upon this [`unable to sign zipexception`][2] if you encounter with any `zipexception` error . So overall,use following procedure
    
     


 1.  `keytool -genkey -v -keystore debug.keystore -alias android -keyalg RSA -keysize 2048 -validity 20000`
 2. `jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore    yourapkalign.apk alias_name`
 3. `zipalign -v 4 yourapk.apk yourapkalign.apk`
 
Now,you can successfully install the apk file.

It means that the apk you downloaded hasn&#39;t been signed with any certificate, debug or otherwise.

You can sign it from the command line, as described [here][1].


  [1]: http://developer.android.com/tools/publishing/app-signing.html

You can use the `androiddebugkey` the sign the apk.

The keystore lives in `~/.android`, named `debug.keystore`.

Run 

`keytool  -list -keystore ~/.android/debug.keystore`

To see the debug key, we can see its name is `androiddebugkey`

Run the following command to sign the apk.


```
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ~/.android/debug.keystore yourapp-release.apk androiddebugkey
```



Everyone who programmed with C# knows that there is the Entity Framework as ORM (object-relational mapper) which enable programmer to query database using only C# code. 

For example, if I have a database called `Shop`, and in the `Shop` database I have `Products` table, i can get all product of `Products`table where their price is less than 2 dollar in the following way:

    ShopEntity _Db = new ShopEntity();
    List&lt;Product&gt; products = _Db.Products.Where(p =&gt; p.Price &lt; 2).ToList();

The above code is equivalent to this SQL statement:

    Select * From Products Where Price &lt; 2


I want to know is there any framework like that in Java?

I also saw &lt;a href=&quot;https://stackoverflow.com/questions/1083080/what-are-the-java-equivalents-to-linq-and-entity-framework&quot;&gt;quaere&lt;/a&gt;. But it just queries collections. I want to query  against the database. There is another framework in java called &lt;a href=&quot;http://hibernate.org&quot;&gt;Hibernate&lt;/a&gt; which does not provide good functionality for query the database.


Is there any entity framework equivalent in java?

I want to print out the value of a `size_t` variable using `printf` in C++ using Microsoft Visual Studio 2010 (I want to use `printf` instead of `&lt;&lt;` in this specific piece of code, so please no answers telling me I should use `&lt;&lt;` instead).

According to the post 

&gt; https://stackoverflow.com/questions/2125845/platform-independent-size-t-format-specifiers-in-c

the correct platform-independent way is to use `%zu`, but this does not seem to work in Visual Studio.  The Visual Studio documentation at

&gt; http://msdn.microsoft.com/en-us/library/vstudio/tcxf1dw6.aspx 

tells me that I must use `%Iu` (using uppercase `i`, not lowercase `l`).

Is Microsoft not following the standards here?  Or has the standard been changed since C99?  Or is the standard different between C and C++ (which would seem very strange to me)?

    TextView tv1 = new TextView(this);		
    tv1.setPadding(5, 0, 5, 0);
    tv1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT));
    tv1.setBackgroundColor(Color.parseColor(&quot;#0099cc&quot;));

As you can see, in this peace of code I set `TextView`&#39;s background color. What I want to do is I want to separate both of these `TextView`&#39;s from each other, so that their background colors would be separated by a line. I don&#39;t want them to connect. As I understand, it would be possible to do so, if I could set margins of `TextView`, but as I know, `TextView`&#39;s are not able to do so.

I am making a simple Address Book app (targeting 4.2) that takes name, address, city, state, zip and phone.

I want to format the phone number input as a phone number (XXX) XXX-XXXX, but I need to pull the value out as a string so I can store it in my database when I save. How can i do this??

I&#39;ve been trying to run this batch file that goes through the Postgre DB Server and run two different sql files, as shown below:

    set PGPASSWORD=blah
    cls
    @echo on
    &quot;C:\Progra~1\pgAdmin III\1.16\psql&quot; -d [db name] -h [server name] -p 5432 -U postgres -f C:\query1.sql
    &quot;C:\Progra~1\pgAdmin III\1.16\psql&quot; -d [db name] -h [server name] -p 5432 -U postgres -f C:\query2.sql

But the issue comes that sometimes I will get the following error for either the command for query1 or query2:

    psql: server closed the connection unexpectedly 
    This probably means the server terminated abnormally
    before or while processing the request.

This only happens sometimes, so I&#39;m not entirely sure why it is happening. Can someone explain why this is the case and if there&#39;s a solution to this problem. Thanks!

Update: I also get the same error SOMETIMES when trying to open the remote server in the actual Postgre application: &quot;An error has occured: &quot;server closed the connection unexpectedly 
This probably means the server terminated abnormally
before or while processing the request.&quot;

I also get this Guru Hint thing right after I click out of the error popup:

Database encoding
The database VA-trac is created to store data using the SQL_ASCII encoding. This encoding is defined for 7 bit characters only; the meaning of characters with the 8th bit set (non-ASCII characters 127-255) is not defined. Consequently, it is not possible for the server to convert the data to other encodings. 
If you&#39;re storing non-ASCII data in the database, you&#39;re strongly encouraged to use a proper database encoding representing your locale character set to take benefit from the automatic conversion to different client encodings when needed. If you store non-ASCII data in an SQL_ASCII database, you may encounter weird characters written to or read from the database, caused by code conversion problems. This may cause you a lot of headache when accessing the database using different client programs and drivers. 
For most installations, Unicode (UTF8) encoding will provide the most flexible capabilities. 

Regardless, the server still opens up afterward and I&#39;m able to access the database from that point on.

I have a program, which is running on two processors, one of which does not have floating point support. So, I need to perform floating point calculations using fixed point in that processor. For that purpose, I will be using a floating point emulation library. 

I need to first extract the signs, mantissas and exponents of floating point numbers on the processor which do support floating point. So, my question is how can I get the sign, mantissa and exponent of a single precision floating point number.

Following the format from this figure, 

![enter image description here][1]
That is what I&#39;ve done so far, but except sign, neither mantissa and exponent are correct. I think, I&#39;m missing something.

    void getSME( int&amp; s, int&amp; m, int&amp; e, float number )
    {
    	unsigned int* ptr = (unsigned int*)&amp;number;
    
    	s = *ptr &gt;&gt; 31;
    	e = *ptr &amp; 0x7f800000;
    	e &gt;&gt;= 23;
    	m = *ptr &amp; 0x007fffff;
    }

How to access localhost from a Genymotion android emulator?

I spent the last two days trying to figure out how to debug an HTML5 app I created using Cordova 3.2 and deployed to an Android 2.3 device. All the articles/posts I&#39;ve seen provide hacks rather than real solutions :( and most of the time, none of them works for my case; debug the css styles and the Angularjs code inside my app..

So far I tested;

**debug.phonegap.com**

I injected the script to the `index.html` file then visited the generated URL in debug.phonegap.com but nothing happens; only a blank page.

**Weinre**

Most of the articles I found point to obsolete Github repository that countain a Jar file.. but it&#39;s not found :(

**Edge inspect**

It works and shows the webpage I&#39;m browsing on the PC inside the mobile.. But the problem is that it uses some other integrated browser (or emulator) than the one that runs phonegap apps; so the results are not accurate.

**Chrome emulator**

Same as Edge inspect; it doesn&#39;t allow to view real web-kit v530 that is shipped with Android 2.3.

**The dream solution**

The perfect solution would be an extension to Google Chrome (desktop) that enables you to switch the desktop browser to the same one found in Android 2.3 platforms; no emulation no hacks, just the browser itself with web-kit v 530.

Unfortunately such solution doesn&#39;t exist :( or I&#39;m wrong?

Any suggestions?

I`m asking how to enable my VT/NX for my MacBook, when I try to use X86 emulator, it appears to me that VT/NX NOT ENABLED, it had never seem this when I used 10.9 system, after I update my MacBook to Yosemite, it appears to me.

When I try to start my x86 emulator, it tells me:

	Starting emulator for AVD &#39;X86&#39;
	emulator: ERROR: x86 emulation currently requires hardware acceleration!
	Please ensure Intel HAXM is properly installed and usable.
	CPU acceleration status: HAX is not installed on this machine (/dev/HAX is missing).

But the AVD shows me that I had installed HAXM.

When I try to install by myself again, installer prints `VT/NX NOT ENABLED`.

I can not post any images…

I started using new Android Studio and cant find the APK of the application in IDE,where it actually locates?

Apk location in New Android Studio

I&#39;m developing an Android app with the Android Developer Tool.
Now I tried the new Android Studio, everything works fine if connect my smartphone with the PC and directly run the program in the Android Studio.
But now I want to test the program with other smartphones without connecting them to my PC.

The ADT creates the .apk file under &quot;projectname/bin&quot; every time you compile the program. How I see it at the moment, Android Studio doesn&#39;t do that.

So, my question is: Is it possible to create an unsigned .apk file with Android Studio?


Build unsigned APK file with Android Studio

After updating Android Studio to 0.2.4 I can&#39;t get my project to deploy. There is a complete mismatch of the apk filename.

    Waiting for device.
    Target device: 0146B0020E010020
    Uploading file
    	local path: /home/martin/workspace/git/projectname/projectname/project/build/classes/debug/AppName.apk
    	remote path: /data/local/tmp/com.xxx.xxx.android.projectname
    Local path doesn&#39;t exist.

After reading some posts here, I changed the output path to the build/apk folder, but the issue remains. Instead of the created projectname-debug-unaligned.apk he is looking for the projectname.apk and I have no idea how and where I can tell him to change the name he is looking for. Any ideas?

PS: Yes I have read several posts which are shown in the list on the right side. The restart of the IDE worked for my coworker, but not for me.

**Edit:**

I stumbled from [one issue](https://code.google.com/p/android/issues/detail?id=59010) to the [next](https://code.google.com/p/android/issues/detail?id=59057) so I reverted back to the only downloadable version I could find: 0.2.0.

No disappearing UI elements, I can create new projects and, best of all, I can finally deploy the APK from the studio to my device again. I will try 0.2.5 as soon as it is released.

I would like to have my Gradle build to create a release signed apk file using Gradle.

I&#39;m not sure if the code is correct or if I&#39;m missing a parameter when doing `gradle build`?

This is some of the code in my gradle file:

```groovy
android {
    ...
    signingConfigs {
        release {
            storeFile file(&quot;release.keystore&quot;)
            storePassword &quot;******&quot;
            keyAlias &quot;******&quot;
            keyPassword &quot;******&quot;
        }
    }
}
```

The Gradle build finishes *SUCCESSFUL*, and in my `build/apk` folder I only see the `...-release-unsigned.apk` and `...-debug-unaligned.apk` files. 

Any suggestions on how to solve this?


How to create a release signed apk file using Gradle?
