Invalid application's package name in 'AndroidManifest.xml React native - android

I am trying to set up the app for the play store and I change the package name in the AndroidManifest.xml file. While making the app build I am getting a warning. I try to find the solution but did not get the right answer.
warn Invalid application's package name "com.bilalyaqoob.Animals" in 'AndroidManifest.xml'.
bilalyaqoob is my name and Animals is app name.
Can you please me what I am doing wrong?

You must changes all package name.
If you use Visual Code you can do this.

How to fix "No resource found that matches the given name (at 'value' with value '#integer/google_play_services_version')"

I am getting the following error when I build my Android App project in Visual studio 2015.
No resource found that matches the given name (at 'value' with value '#integer/google_play_services_version')
These lines are located under:
obj\Debug\android\manifest\AndroidManifest.xml
There is 3 entires of it inside the AndroidManifest file.
I have downloaded the google play service from the SDK Manager.
Should I reference anything to my solution?
I already has Xamarin.GooglePlayServices.Base, Xamarin.GooglePlayServices.Basement, Xamarin.GooglePlayServices.Maps Referenced.
Thanks.
you have create integer.xml file inside value folder and define your Integer to that place it will solve your problem.
Try doing and a clean all and check that ALL the content under the obj has been deleted and then perform a build all.
If that does not work:
I would try removing the ~GooglePlayServices~ nugets/references and re-add just the Xamarin.GooglePlayServices.Mapsnuget which will bring in the ~Basement and ~Base libraries.
You should end up with a generated manifest that only has one reference to google_play_services_version and that resource should be picked up from Debug/android/XXX/YYYYYY/ZZZZZ/R.java:
i.e.
public static final int google_play_services_version=0x7f070000;
I added several new packages. One of the package is the reason of the error. I have to check one by one and caught the one causing error. Removing that package is all I need to do to resolve the error.

error: <identifier> expected with package com.native

I followed this instructions to setup android requirements and initiate a project with react-native. When I try to run the application using the command react-native run-android, it keeps showing this error then exiting the process.
/path/to/native/android/app/src/main/java/com/native/MainActivity.java:1: error: <identifier> expected
package com.native;
^
The package name should not be a language tag.
Try the other keyword for the package
Like
package com.nativeapp or package com.appnative
As android relies on java to compile code, packages names fall under java reserved words restrictions, native is one of them. full list in Oracle documentation.
You also will have to avoid javascript reserved keyword defined in ECMA documentation.
Try changing any other package name as given package name is not a valid package name for android/java.

Error when uploading apk to playstore, apk name not valid

I developed my very first android app but when i'm uploading to the Play Store I get the following error:
error
For those not speaking dutch," upload failed, the name of your apk has to be the following format 'com.example.myapp'. I'm guessing I didn't do this but I have no idea how to fix this. I'm using Android Studio 0.6.1
I did search the web but couldn't find a fix.
It is the name of the package of your app i.e bundle identifier. Also example cannot be used in it. For more info: Android - Package Name convention
change the package name
(com.example) is invalid.
use (com.xyz).
xyz means any thing u like but not example

changing the laucher2 package name android

I am trying to implement my own launcher (making some modifications to the launcher provided by google ). But since i cant remove the default launcher i renamed my package name and everything . Initially the package name was com.android.launcher2 . I changed every instance it to com.rohit.grid . Now if I run it i am getting this error 'Re-installation failed due to different application signatures' .Now the manifest file has some something called com.android.launcher in the permission tags & in the packge name . If i replace it with com.rohit.grid I will get errors in xml files about some resource being not resolved.
I tried cleanoing the project, fixing its properties & everything . But it dint help .
Somebody plz get me out of this problem .
Thanks in advance.
Regards,
Rohit
I think 'Re-installation failed due to different application signatures' means that the installer is trying to install an APK with the same name that an installed one, but the problem in this case is that the installed is signed with a different key than yours.
Instead of modifying your manifest try to rename the project and then reinstall.
