HERE Map SDK configure with multiple build variants with different applicationId

How can I use HERE map SDK with multiple build variants with different applicationId
like - com.example and com.example.debug
There is only one input for package name in HERE map console.

If you use the Navigate or the Explore Edition of the 4.x HERE SDK for Android, you can choose any package name you like and it's possible to reuse the same credentials for multiple apps.

Package name would be unique and there is only one option for package name.
Name (such as HelloMap) and Organization Identifier (such as edu.self)

Android applications with differnt package names are not able to install in same device.

I created two apk files with package name com.example.a and com.example.a.staging. But I am not able to install the both on the same device together. It will install separately.While try to install one after installed the other, it shows an error 'app not installed'

i have faced similar situations.
possible scenarios:
1.you didn't change applicationId in app/gradle.
Solution: In that case, change applicationId.
2.you have a defined a provider for facebook(or something similar) in AndroidManifest.xml like android:authorities="com.facebook.app.FacebookContentProviderXXXX.
Solution: Comment out that provider for testing or add different ids for providers for different build variants.

first, you change package name in your manifest file, then you paste the changed package name to your build.gradle(app level) on applicationId place

Install duplicated Android app on your device

I want to install on my phone the production and development apks of my Android app, which initially are going to be exactly the same.
The only thing that I have changed so far is <application android:label="#string/app_name"> in the AndroidManifest.xml to a different string.
However, when I try to install the new APK on my device, it detects the app as an update of the production one.
What can I do to make my phone understand that these are two different apps?

You have to change the applicationId of the app.
That is used as a unique identifier in the play store and on your phone.
The applicationId is in your build.gradle in the main app folder:
defaultConfig {
applicationId "com.example.myapp"
During the build gradle will generate the package name in your manifest from the applicationId.

You have to change to package name of application. Then you can easy to install application different one.
com.something.somthing set on you application package.
Change at project/src/com.package.package
And chnage at manifest

Change Application Package name through Android Studio

I am aware that this question is asked several times in SO. I have checked below answers posted but doesn't work for me :(
Solution 1
Solution 2
Currently, my application's package name is "com.example.test".I want to change this to "com.example.test.test1".So, I just changed the package name in my manifest file and build the app.
Now ,if I run both the applications seperately with above package names changed from manifest files into device than it should show me different applications.It shows me error as "Failure [INSTALL_FAILED_CONFLICTING_PROVIDER]"
As the package names are different, it should show me different applications in the device instead of overriding one app with other.Help me out.
Any help would be appreciated.Thanks

The packageName attribute is deprecated as of Android Studio V0.0.6 onward. To change the package name of the application, use applicationId instead. Check the release notes here.
Change the applicationId and sync gradle.

If your aim is to have the same application at two instance in the device, it is so easy to do using gradle. You don't need to change package name in the Manifest file, gradle will handle that during the build process for you and do all package renaming under the hood wherever required.
In order to achieve that you need to write a new product flavor for your app inside the main app module's build.gradle file with a different application id(package name). Eg. if com.example.test is your default package name of the app. You can have a different flavor of the same app with a different package name or knows as application id. produltFlavours can be defined inside android tag of your main module's build.gradle file like as shows below.
productFlavors {
app1 {
applicationId "com.example.test.test1"
}
}
Sync your project after making the changes. Now select the build variant from Build Variant tab in left hand panel and hit run. Gradle script will handle all package renaming for you.
Check this once for more details :
Android Gradle Build Variant Deploy

What worked for me:
1. Right click package you want to change under java folder|
2. Refactor -> Rename|
3. Rename the package -> press "enter" -> press "Do Refactor"|
4. This updates all the files including the manifest

"com.example is restricted" when uploading APK to Play Store

I am trying to upload my finished android app to the android market and I am getting this error:
You need to use a different package name because "com.example" is restricted.

In Android Studio after renaming Package then go "build.gradle (Module:App)
defaultConfig {
applicationId "com.example.android.abc"
minSdkVersion 9
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
change the line
applicationId "com.example.android.abc"
to
applicationId "com.tanxe.android.abc"
relpace "tanxe" with the word you want or your Organization name i.e.
your new package name
and rebuild the project

The best way to solve this is by going to the AndroidManifest.xml: package="com.example.android.yts"
Cursor on example
press
Shift+f6
change Package name eg. example to boss
Click on refactor now `"com.boss.android.yts"``
2nd thing
open build.gradle (module:app) change applicationId "com.example.android.yts"
to "com.boss.android.yts"

The error message is telling it all. You need to use a package name of your own. The package name is the identitiy of the application.
To rename the package name, In eclipse right click on the project in project explorer. Then Android Tools > rename Aplication Package name. Then enter the new package name.
Also make sure that you are trying to upload a release build

Yes, com.example is the default package name for Android applications and is, as such, just a placeholder. You should replace it by a unique package name before uploading it to the Google Play Store. It doesn't particularly matter what it is, but it should relate to your application, cannot match any existing package name (so picking someone else's package name like com.android is not a good idea), and cannot be changed after publishing.

Double-tap **package** from AndroidManifest.xml, refactor-> rename.
Go to build.gradle and change applicationId under defaultConfig.
If you have google-services.json, go to google-services.json and rename package_name in two places.
That should work.

Write something else than the com.example
for ex:
com.gg.s etc will do(make that onj your name/firm name)
