Step 3: Describe the problem:

Adding Hilt to the project causes AuthMethodPickerActivity to fail to launch with this error: "You need to use a Theme.AppCompat theme (or descendant) with this activity."

Steps to reproduce:

2. __Added Hilt libraries and the app crashes

3. ---

Observed Results:

• What happened? This could be a description, logcat output, etc.

Process: io.zsoft.firebaseuiminimum, PID: 31152 java.lang.RuntimeException: Unable to start activity ComponentInfo{io.zsoft.firebaseuiminimum/com.firebase.ui.auth.ui.idp.AuthMethodPickerActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity. at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:3685)

Expected Results:

• What did you expect to happen? Successful display of FirebaseUI AuthMethodPickerActivity

Relevant Code:

// TODO(you): code here to reproduce the problem

val signInLauncher = rememberLauncherForActivityResult(contract = FirebaseAuthUIActivityResultContract()) {
      val response = it.idpResponse
      Log.e("signInLauncher", "response = ${response.toString()}")
      if (it.resultCode == Activity.RESULT_OK) {
          Log.e("signInLauncher", "signed in OK")
      } else {
          Log.e("signInLauncher", "sign in error = ${response?.error}")
      }
  }
  Button(modifier = Modifier.wrapContentSize(), onClick = {
      val providers = arrayListOf(
          AuthUI.IdpConfig.EmailBuilder().build(),
          AuthUI.IdpConfig.PhoneBuilder().build(),
          AuthUI.IdpConfig.GoogleBuilder().build(),
      )
      val signInIntent = AuthUI.getInstance()
          .createSignInIntentBuilder()
          .setIsSmartLockEnabled(false)
          .setAvailableProviders(providers)
          .build()
      signInLauncher.launch(signInIntent)
  }) {
      Text("Authenticate")
  }

The above code works fine without Hilt in the project. Adding just one dependency (implementation "com.google.dagger:hilt-android:2.44") somehow crashes the App

Firebase requires appcompat dependency, you should add

implementation("androidx.appcompat:appcompat:1.6.1")
