Android Question B4XPages, Splash Screen + Biometric

[bobbyh]

Hi,

I'm a new b4xpages , I'm trying to create a splash screen + biometric.

[B4X] [B4XPages] Splash Screen

B4A, B4i and B4J splash screen implementation. The implementation is different in each platform. 1. Don't miss the manifest editor code in B4A. 2. Don't use %y in the code. Use Root.Height instead (you can use %y in the designer script).

and

BiometricManager - Biometric Authentication

This class replaces FingerprintManager (https://www.b4x.com/android/forum/threads/fingerprint-authentication.72500/#content). It works with all the device supported biometric authentication features. Setup: 1. Open B4A Sdk Manager, search for biometric and install androidx.biometric:biometric...

manifest editor :

AddManifestText(
<uses-sdk android:minSdkVersion="21" android:targetSdkVersion="30"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
CreateResourceFromFile(Macro, Themes.LightTheme)
'End of default text.
SetActivityAttribute(Main, android:theme, "@style/DarkTheme")
CreateResource(values, theme.xml,
<resources>
    <style
        name="DarkTheme" parent="@android:style/Theme.Material.Light.NoActionBar.Fullscreen">
          <item name="android:windowBackground">@color/window</item>
    </style>
</resources>
)

CreateResource(values, colors.xml,
<resources>
    <color name="window">#FF5B7BFF</color>
</resources>
)

AddPermission(android.permission.USE_BIOMETRIC)
AddPermission(android.permission.USE_FINGERPRINT)
SetApplicationAttribute(android:theme, "@style/MyAppTheme")
CreateResource(values, theme.xml,
<resources>
    <style name="MyAppTheme" parent="Theme.AppCompat.Light">
    </style>
</resources>
)

I have an error when I run it.

Thanks for helping.

Please create a small project with the relevant code and manifest and upload it.

This is an example project

 

[Erel]

Step 1:
In the manifest editor change the first theme.xml to theme2.xml. Otherwise the second call will overwrite the first one.

Step 2:
Move #Extends: android.support.v7.app.AppCompatActivity from Main activity to Activity2.
Activity2 is the activity that hosts the B4XPages.
