Cannot find symbol: PackageManager.FEATURE_IRIS #3

Closed pratik037 closed 3 years ago

pratik037 commented 5 years ago

I am using _flutter_lock_screen(^1.0.5)_ plugin along with _local_auth(0.6.0)_ in my project. When I am trying to build the project but it keeps returning the same error everytime. I have changed the FlutterActivity to FlutterFragmentActivity as given in the documentation The Fingerprint permission is also added to the AndroidManifest.xml file

Seems like this constants aren't available in the package.

pratik037 commented 5 years ago

Seems like this constants aren't available in the package.

I checked the file and it is there, but it should be invoked only when the API target is greater than 29, which isnt true in my case.

pratik037 commented 5 years ago

@ibhavikmakwana this is the implementation in the package.


PackageManager packageManager = activity.getPackageManager();
        if (Build.VERSION.SDK_INT >= 23) {
          if (packageManager.hasSystemFeature(PackageManager.FEATURE_FINGERPRINT)) {
            biometrics.add("fingerprint");
          }
        }
        if (Build.VERSION.SDK_INT >= 29) {
          if (packageManager.hasSystemFeature(PackageManager.FEATURE_FACE)) {
            biometrics.add("face");
          }
          if (packageManager.hasSystemFeature(PackageManager.FEATURE_IRIS)) {
            biometrics.add("iris");
          }
        }
        result.success(biometrics);
      } catch (Exception e) {
        result.error("no_biometrics_available", e.getMessage(), null);
      }
    } else {
      result.notImplemented();
    }

Hey I tried your example by cloning it in my local system, got the same error as before along with something more;

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':local_auth:compileDebugJavaWithJavac'.
> Compilation failed; see the compiler error output for details.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Which sdk version are you using? conpileSdkVersion should be 28

pratik037 commented 5 years ago

Which sdk version are you using? conpileSdkVersion should be 28

Yes compileSDK version is 28. And the recently posted error is from your own example. I cloned your repository and executed the example folder files using VSCode.

kalismeras61 commented 5 years ago

It is interesting i tested it working fine.

pratik037 commented 5 years ago

It is interesting i tested it working fine.

How? I seriously cloned your project into my local system, opened the example folder in VSCode and pressed Ctrl+F5 to start debugging

pratik037 commented 5 years ago

Here's the app level build.gradle file from the example project

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.flutterpasscodeexample"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug

    }

I'am sorry but i test with stable version and also master version of Flutter. I did'nt see any error. Could you run flutter clean and try again?

Sure thing. Also let me know what changes to make so that this plugin becomes useable in my app. I'll update here after running flutter clean.

I switched to master branch too for trying this out but same output. Can you guide me through what to do, honestly I have no idea why its not working.

kalismeras61 commented 5 years ago

I dont know what exactly going on. Be sure your android studio is latest version and your build tools is greater than 27. Upgrade your gradle version.

I saw first comment everything is fine. Did you test it with emulator?

Yes, everything is up to date, i have tools for 27,28,29. And yes i have tried on emulator too, giving me the same issue :(

kalismeras61 commented 5 years ago

The logs are not clear. Can you run adb logcat ?

pratik037 commented 5 years ago

Sure thing. Sorry got caught up with something and didn't reply.

pratik037 commented 5 years ago

@kalismeras61 I am new to use adb logcat. Should I paste the entire output, or do I need to run it with specific flags?
