I want to know that what should be the package name of android app? Means normally we used com.appname OR com.organizationName.appName, But when we are submitting our application in to market then sometimes it shows the errors related to the package name that- Please change Package name. It should not be started with com etc..
I want to know why this happnes? And what should be Right the package name for android application?
If anyone knows the reason or answer of this question then please let me know.
As stated here: Package names are written in all lower case to avoid conflict with the names of classes or interfaces.
Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com.
Name collisions that occur within a single company need to be handled by convention within that company, perhaps by including the region or the project name after the company name (for example, com.example.region.mypackage).
Packages in the Java language itself begin with java. or javax.
In some cases, the internet domain name may not be a valid package name. This can occur if the domain name contains a hyphen or other special character, if the package name begins with a digit or other character that is illegal to use as the beginning of a Java name, or if the package name contains a reserved Java keyword, such as "int". In this event, the suggested convention is to add an underscore. For example:
Android follows the same naming conventions like Java,

As you stated, package names are usually in the form of 'com.organizationName.appName' - all lowercase and no spaces. It sounds like the package name that you entered when uploading the app was different from the one declared in the AndroidManifest.
Presently Package name starting with "com.example" is not allowed to upload in the app -store.
Otherwise , all other package names starting with "com" are allowed .
Visit https://developers.google.com/mobile/add and try to fill "Android package name". In some cases it can write error: "Invalid Android package name".
In https://developer.android.com/studio/build/application-id.html it is written:
And although the application ID looks like a traditional Java package
name, the naming rules for the application ID are a bit more
restrictive:
It must have at least two segments (one or more dots).
Each segment must start with a letter.
All characters must be alphanumeric or an underscore [a-zA-Z0-9_].
So, "0com.example.app" and "com.1example.app" are errors.
Package name is the reversed domain name, it is a unique name for each application on Playstore. You can't upload two apps with the same package name.
You can check package name of the app from playstore url
https://play.google.com/store/apps/details?id=package_name
so you can easily check on playstore that this package name is in used by some other app or not before uploading it.
package name with 0 may cause problem for sharedPreference.
(OK) con = createPackageContext("com.example.android.sf1", 0);
(Problem but no error)
con = createPackageContext("com.example.android.sf01", 0);

Android - Package Name convention
(7 answers)
Closed 3 years ago.
I want to make an app which i want to publish to the play store.
While creating the app it requires a package name which is something like
com.example.myapp
On doing some research i came to know that it specifies a domain name and is used to uniquely identify our app on play store.
I wanted to know how these packages name work and how do i get the assurity that no other app on play store wont have the same package name as mine.
Also usually when we start android studio it gives a package name com.example.mpapplication. What happens if i try to publish the app with this package name?
Package name uses a “reverse DNS” convention in which the domain name is reversed and suffixed with further identifiers.
This convention keeps package names unique and distinguishes applications from each other on a device and on Google Play.
You don't need to own a .com domain in order to release apps on Play store. It is just a standard. So, Pick some unique name and suffix it with "com. "
If you want to check whether the name you picked is unique or not, simply add it to the following url : https://play.google.com/store/apps/details?id=com.vspinsight.appik.mehangai
Here id=" " is the package name of my app. If the url takes you to an app, that means the package name is already taken.
In some locales, a person's full name is written out with last name (family name, surname) then first name (personal name, given name), instead of the more common first name then last name order.Is there any API in Android which can take care of this name ordering for my app depending on the locale of the phone.
I'm afraid, there's no API for that. I've been looking fot it for a while and all that i know is what #Shervin shared.
Currently:
You can try to manage that all yourself, by getting title, name, second name and last name from user. In english it's easy to order it correctly and concatenate it with space. Unfortunately - not every language use spaces.
Research:
CLDR is project providing any locale-specific data (for example in ICU), but order of name and family name is not there.
Possible solution:
Most of solutions out there can be summed up to:
If designing a form or database that will accept names from people
with a variety of backgrounds, you should ask yourself whether you
really need to have separate fields for given name and family name.
Sometimes you may opt for separate fields because you want to be able
to use part of the name to address the person directly, or refer to
them. For example, when Google+ refers to "Richard's contacts". Or
perhaps it's because you want to send them emails with their name at
the top. Note that not only may you have problems due to name syntax
here, but you also have to account for varying expectations around the
world with regards to formality (not everyone is happy for a stranger
to call them by their given name). It may be better to ask separately,
when setting up a profile for example, how that person would like you
to address them.
http://www.w3.org/International/questions/qa-personal-names#fielddesign
So you must choose if you need to ask your user separately for first name and last name (should be usefull in sorting), but even then - you need to know how they name should be displayed.
Mostly you'll see form that asks users to provide: First name, Last name and Displayed name. Check here (fourth heading) for explanation.
What are the package names like "com.example.etc." in Android Studio representing? Does it actually have any association with the domain and website? Many tutorials I have read state to use a domain name you own. Why is this?
When releasing your application on the market, your application needs an unique package name. This will correspond to the ID on the market.
So choose a package name like your own domain, or your name... in order to have something unique.
Your package is is your Id when U upload in play store , It will recognize only by Id which is package name ,
Please give as com.companyname.appname.
Hi I am new to android and trying to publish on Google play first time.
I am getting error when uploading apk file saying file name should be in format com.example.myapp.apk
my package name is androidapplication1.androidapplication1.apk
there is no com in it!
is this the source of issue?
androidapplication1.androidapplication1.apk sounds like the file name of your application, not its package name. An apk file name shouldn't have more than one dot in it I believe.
The package name on the other hand should have multiple dots. The package name can be found in your manifest xml file. What does it say for that one?
Have a look here.Taken from the developer site:
A full Java-language-style package name for the application. The name should be unique. The name may contain uppercase or lowercase letters ('A' through 'Z'), numbers, and underscores ('_'). However, individual package name parts may only start with letters.
To avoid conflicts with other developers, you should use Internet domain ownership as the basis for your package names (in reverse). For example, applications published by Google start with com.google. You should also never use the com.example namespace when publishing your applications.
The package name serves as a unique identifier for the application.
It's also the default name for the application process (see the
element's process process attribute) and the default
task affinity of an activity (see the element's
taskAffinity attribute).
Caution: Once you publish your application, you cannot change the
package name. The package name defines your application's identity, so
if you change it, then it is considered to be a differen
t application and users of the previous version cannot update to the new version.
I created a sample app in my own development server with your package name androidapplication1.androidapplication1.apk . I didnot receive any errors. So you can either ask google for this issue or ensure that this package is not used by anyone in the play store.
The package naming convention in Android is:
com.organizationName.appName
But if the organizationName or the appName starts with a number or underscore, it becomes a invalid name, since android doesn't accept words that start with number or underscore.
For example:
com.1organizationName.appName is invalid
What is the convention to rename this package?
In the official "Naming a Package" java documentation, it has the following statement:
In some cases, the internet domain name may not be a valid package
name. This can occur if the domain name contains a hyphen or other
special character, if the package name begins with a digit or other
character that is illegal to use as the beginning of a Java name, or
if the package name contains a reserved Java keyword, such as "int".
In this event, the suggested convention is to add an underscore.
So in your case, it would be com._1organizationname.appname
EDIT: Just found this in the Android docs:
A full Java-language-style package name for the application. The name
should be unique. The name may contain uppercase or lowercase letters
('A' through 'Z'), numbers, and underscores ('_'). However, individual
package name parts may only start with letters.
So apparently it's not quite Java-style. Unfortunately, it looks like your best bet in this case would in fact be to spell out the number, e.g. com.oneorganizationname.appname.
The naming convention is merely to help you create a unique package name for the Play market. If you use your company's website address backwards (i.e. com.websitename.appname), then it's unlikely another app in the Play market will have it. You can name the package whatever you want so you can spell the number out to make it easier (com.oneOrganizationName.appName).
See here about the "package" attribute in the manifest:
A full Java-language-style package name for the application. The name
should be unique. The name may contain uppercase or lowercase letters
('A' through 'Z'), numbers, and underscores ('_'). However, individual
package name parts may only start with letters. To avoid conflicts
with other developers, you should use Internet domain ownership as the
basis for your package names (in reverse). For example, applications
published by Google start with com.google. You should also never use
the com.example namespace when publishing your applications.
The package name serves as a unique identifier for the application.
It's also the default name for the application process (see the
element's process process attribute) and the default
task affinity of an activity (see the element's
taskAffinity attribute).
you can try co.m_1organizationName.appName or co.m1organizationName.appName this way your package will not be absurd and the address will be more meaningful.
You know, it only costs like $5 to register a new domain name. Just register oneorganizationName.com and use that. You know it will be unique, you know it will be a valid package name, and now you know that phishers and spoofers won't be registering oneorganizationName.com for themselves to trick your customers.
