Our Pledge 4 | 5 | We as members, contributors, and leaders pledge to make participation in our 6 | community a harassment-free experience for everyone, regardless of age, body 7 | size, visible or invisible disability, ethnicity, sex characteristics, gender 8 | identity and expression, level of experience, education, socio-economic status, 9 | nationality, personal appearance, race, religion, or sexual identity 10 | and orientation. 11 | 12 | We pledge to act and interact in ways that contribute to an open, welcoming, 13 | diverse, inclusive, and healthy community. 14 | 15 | ## Our Standards 16 | 17 | Examples of behavior that contributes to a positive environment for our 18 | community include: 19 | 20 | * Demonstrating empathy and kindness toward other people 21 | * Being respectful of differing opinions, viewpoints, and experiences 22 | * Giving and gracefully accepting constructive feedback 23 | * Accepting responsibility and apologizing to those affected by our mistakes, 24 | and learning from the experience 25 | * Focusing on what is best not just for us as individuals, but for the 26 | overall community 27 | 28 | Examples of unacceptable behavior include: 29 | 30 | * The use of sexualized language or imagery, and sexual attention or 31 | advances of any kind 32 | * Trolling, insulting or derogatory comments, and personal or political attacks 33 | * Public or private harassment 34 | * Publishing others' private information, such as a physical or email 35 | address, without their explicit permission 36 | * Other conduct which could reasonably be considered inappropriate in a 37 | professional setting 38 | 39 | ## Enforcement Responsibilities 40 | 41 | Community leaders are responsible for clarifying and enforcing our standards of 42 | acceptable behavior and will take appropriate and fair corrective action in 43 | response to any behavior that they deem inappropriate, threatening, offensive, 44 | or harmful. 45 | 46 | Community leaders have the right and responsibility to remove, edit, or reject 47 | comments, commits, code, wiki edits, issues, and other contributions that are 48 | not aligned to this Code of Conduct, and will communicate reasons for moderation 49 | decisions when appropriate. 50 | 51 | ## Scope 52 | 53 | This Code of Conduct applies within all community spaces, and also applies when 54 | an individual is officially representing the community in public spaces. 55 | Examples of representing our community include using an official e-mail address, 56 | posting via an official social media account, or acting as an appointed 57 | representative at an online or offline event. 58 | 59 | ## Enforcement 60 | 61 | Instances of abusive, harassing, or otherwise unacceptable behavior may be 62 | reported to the community leaders responsible for enforcement at 63 | abhishek.i@simformsolutions.com. 64 | All complaints will be reviewed and investigated promptly and fairly. 65 | 66 | All community leaders are obligated to respect the privacy and security of the 67 | reporter of any incident. 68 | 69 | ## Enforcement Guidelines 70 | 71 | Community leaders will follow these Community Impact Guidelines in determining 72 | the consequences for any action they deem in violation of this Code of Conduct: 73 | 74 | ### 1. Correction 75 | 76 | **Community Impact**: Use of inappropriate language or other behavior deemed 77 | unprofessional or unwelcome in the community. 78 | 79 | **Consequence**: A private, written warning from community leaders, providing 80 | clarity around the nature of the violation and an explanation of why the 81 | behavior was inappropriate. A public apology may be requested. 82 | 83 | ### 2. Warning 84 | 85 | **Community Impact**: A violation through a single incident or series 86 | of actions. 87 | 88 | **Consequence**: A warning with consequences for continued behavior. No 89 | interaction with the people involved, including unsolicited interaction with 90 | those enforcing the Code of Conduct, for a specified period of time. This 91 | includes avoiding interactions in community spaces as well as external channels 92 | like social media. Violating these terms may lead to a temporary or 93 | permanent ban. 94 | 95 | ### 3. Temporary Ban 96 | 97 | **Community Impact**: A serious violation of community standards, including 98 | sustained inappropriate behavior. 99 | 100 | **Consequence**: A temporary ban from any sort of interaction or public 101 | communication with the community for a specified period of time. No public or 102 | private interaction with the people involved, including unsolicited interaction 103 | with those enforcing the Code of Conduct, is allowed during this period. 104 | Violating these terms may lead to a permanent ban. 105 | 106 | ### 4. Permanent Ban 107 | 108 | **Community Impact**: Demonstrating a pattern of violation of community 109 | standards, including sustained inappropriate behavior, harassment of an 110 | individual, or aggression toward or disparagement of classes of individuals. 111 | 112 | **Consequence**: A permanent ban from any sort of public interaction within 113 | the community. 114 | 115 | ## Attribution 116 | 117 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], 118 | version 2.0, available at 119 | https://www.contributor-covenant.org/version/2/0/code_of_conduct.html. 120 | 121 | Community Impact Guidelines were inspired by [Mozilla's code of conduct 122 | enforcement ladder](https://github.com/mozilla/diversity). 123 | 124 | [homepage]: https://www.contributor-covenant.org 125 | 126 | For answers to common questions about this code of conduct, see the FAQ at 127 | https://www.contributor-covenant.org/faq.

And if there are no biometric sensors present, the API allows developers to specify whether they want to use device credentials in their apps. 11 | 12 | ### About this project : 13 | * This applications is sample for Biometrics Authentication in Android using Biometrics API 14 | 15 | | Finger Print Unlock | Face Unlock | 16 | |--|--| 17 | | ![](biometrics.gif) | ![](face_unlock.gif) | 18 | 19 | ### This application provides the below feature 20 | 21 | * Fingerprint Authentication 22 | * Face Authentication 23 | * PIN/Password/Pattern Authentication 24 | 25 | ### How it works : 26 | 1. Add the Gradle dependency to your app module 27 | 28 | ```groovy 29 | def biometric_version= '1.2.0-alpha04' 30 | implementation "androidx.biometric:biometric:$biometric_version" 31 | ``` 32 | 33 | 2. Check whether the device supports biometric authentication 34 | 35 | ```kotlin 36 | val biometricManager = BiometricManager.from(context) 37 | if(biometricManager.canAuthenticate() == BiometricManager.BIOMETRIC_SUCCESS){ 38 | // you can authenticate with biometrics 39 | } 40 | ``` 41 | 42 | 3. Create an instance of BiometricPrompt 43 | 44 | ```kotlin 45 | private fun instanceOfBiometricPrompt(): BiometricPrompt { 46 | val executor = ContextCompat.getmainExecutor(context) 47 | val callback = object:BiometricPrompt.AuthenticationCallback() { 48 | override fun onAuthenticationError(errorCode: Int, errString: CharSequence) { 49 | super.onAuthenticationError(errorCode, errString) 50 | showMessage("$errorCode :: $errString") 51 | } 52 | override fun onAuthenticationFailed() { 53 | super.onAuthenticationFailed() 54 | showMessage("Authentication failed for an unknown reason") 55 | } 56 | override fun onAuthenticationSucceeded(result: BiometricPrompt.AuthenticationResult{ 57 | super.onAuthenticationSucceeded(result) 58 | showMessage("Authentication was successful") 59 | } 60 | } 61 | val biometricPrompt = BiometricPrompt(context, executor, callback) 62 | return biometricPrompt 63 | } 64 | ``` 65 | 66 | 4. Build a PromptInfo object 67 | 68 | ```kotlin 69 | promptInfo = BiometricPrompt.PromptInfo.Builder() 70 | .setTitle("Biometric login for my app") 71 | .setSubtitle("Log in using your biometric credential") 72 | // Can't call setNegativeButtonText() and // setAllowedAuthenticators(... or DEVICE_CREDENTIAL) at the same time.// 73 | //.setNegativeButtonText("Use account password") // 74 | .setAllowedAuthenticators(BIOMETRIC_WEAK or DEVICE_CREDENTIAL) 75 | .build() 76 | ``` 77 | 78 | 5. Ask the user to authenticate 79 | 80 | ```kotlin 81 | biometricPrompt.authenticate(promptInfo) 82 | ``` 83 | 84 | ### For API level 21 -23 : 85 | * For API level 21-23, you need to check whether Screen lock is enabled or not before authentication. 86 | ```kotlin 87 | keyguardManager = getSystemService(KEYGUARD_SERVICE) as KeyguardManager 88 | if (keyguardManager.isKeyguardSecure) { 89 | //Screen lock is enabled, do authentication. 90 | } 91 | ``` 92 | * If screen lock is not enabled than use below code to navigate user to setting screen for set up of Screen lock. 93 | ```kotlin 94 | startActivityForResult(Intent(Settings.ACTION_SECURITY_SETTINGS), REQUEST_CODE) 95 | ``` 96 | 97 | For more info go to __[Android Developers Biometric
