When I add the chip-group, The program does not work

Question

I got a problem in the Chip-Group section. This is the first time I use the Chip and Chip-Group, so I must download it. When I clicked the download button. They ask me: "This operation requires the library com.google.android.material:material:+, Would you like to add this now? " If I press the Yes button, Material is added correctly but with an error.

when I clicked the run button I got an error.

the error message is :

    //This is added after press yes.
    implementation 'com.google.android.material:material:1.0.0'


}

If I remove the material from the code

('com.google.android.material:material:1.0.0')

My program works correctly.

help me

• First migrate your project to androidX going to refactor -> Migrate to androidX.
• Add dependency implementation 'com.google.android.material:material:1.0.0'
  or
  implementation 'com.google.android.material:material:1.1.0-alpha08'

Then use Chip-Group as:

<com.google.android.material.chip.ChipGroup
     android:id="@+id/reflow_group"
     android:layout_width="match_parent"
     android:layout_height="wrap_content">

     <com.google.android.material.chip.Chip
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="@string/txt_this" />
</com.google.android.material.chip.ChipGroup>
