Keytool is not recognized as internal or extenal command / Adding PATH in system variable

If you are running a keytool command
keytool -list -v -keystore C:\Users\arun\.android\debug.keystore -alias androiddebugkey -storepass android
and getting an error
'keytool' is not recognized as an internal or external command

If you are using any other commad like java,javac , etc.. and getting an error " is not recognized as an internal or external command"
you can also use this same steps

you are getting this error because keytool.exe , executable file which exists in the bin directory of your JDK is not added to Path in your Environmental variables. To resolve this issue

1.first we need to find the bin Directory of our jdk
Usually this will be in C:\Program Files\Java\jre1.8.0_221\bin
(jre1.8.0_221 - change this to your latest version , ). you can see keytool.exe file in the bin directory . (If you installed jdk in a different directory Find your Jdk installation folder and use that path.)

2. we need to add this bin directory to PATH in Environment variables
3. Go to Advanced system settings .
I. If you are using windows 10, search for advanced system settings in search bar

II.or go to control panel->system And Security

III.click on system and click advanced system settings in left side

4. Click on environment variables In Advanced system settings

5. Select path and click Edit in Environment variables

6. click New and add your jdk bin path

7.click ok .now you are ready to to go
8. open your command prompt and run the command

ViewModel with Jetpack Compose

Compose uses remember API to store object in memory. Stored value is returned during recomposition . remember helps us retain data across recompostion , but when configuration changes happen all stored values are lost . One way to overcome this is to use rememberSaveable . rememberSaveable saves any value that can be saved in a Bundle , so it will survive configuration changes. But when we are using lot of data , for example a list we can cannot use a rememberSavble beacuse there is limit on amount of data that can be stored in Bundle . So we use ViweModel . ViewModel provide the ui state and access to the business logic located in other layers of the app. It also survives configuration changes. ViewModel handles events coming from the UI or other layers of the app and updates the state holder based on the events. We need to add the following dependency in our app level build.gradle to use ViewModel implementation "androidx.lifecycle:lifecycle-viewmodel-compose:2.4.1" F...
