android material design, cardview not added corner radius to phone
I have a Cardview inside android X
<androidx.cardview.widget.CardView android:id="@+id/card_box_register" android:layout_width="match_parent" android:layout_height="360dp" android:layout_marginStart="16dp" android:layout_marginTop="226dp" android:layout_marginEnd="16dp" android:layout_marginBottom="16dp" card_view:cardBackgroundColor="@color/white" card_view:cardCornerRadius="36dp" card_view:cardElevation="8dp"/> On the surface, everything is fine and tidy, but when I export(apk) the application, none of the corner radius attributes apply to the card view. To understand more about this, you can look at the photos below 
This may be because you have set the hardware acceleration to false on the manifest(application level) or on the activity level ,if this is the case then add this piece of code to your manifest’s application tag
<application android:hardwareAccelerated="true" ...>
or in your activity level (in the manifest)
<application android:hardwareAccelerated="true"> <activity ... /> <activity android:hardwareAccelerated="false" /> have a look at the full documentation here
manifest.xml
<application android:name=".application" android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:hardwareAccelerated="true" android:theme="@style/AppTheme"> <activity android:name=".activity.RegisterActivity" /> <activity android:name=".activity.SplashActivity" android:theme="@style/Splash"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>
