I would like to perform fingerprint authentication on android and add this line into the build.gradle(you can see it at pastebin), but then it give me error messages
Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.1.0] AndroidManifest.xml:24:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add ‘tools:replace=”android:appComponentFactory”‘ to <application> element at AndroidManifest.xml:6:5-63:19 to override.
As their suggestions, I change the xml file like this(at pastebin)
But then it give me error messages like these
Validation failed, exiting
See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ‘:processDebugManifest’.
> Manifest merger failed with multiple errors, see logs
After that I add one more line to the application of manifest
<span class="pln">android</span><span class="pun">:</span><span class="pln">appComponentFactory</span><span class="pun">=</span><span class="str">"whateverString"</span>
Then it give me following error message–at pastebin
