Lock Screen

Simple and beautiful Lock Screen library to set an check pin code. Integrated with fingerprint authentication.

Easily secure your app with Lock Screen library as easy as starting an intent.

With great animations for fingerprint authentication.

Set Pin:

Check Pin:

Lock Screen gets a 4 digit pincode from user at first running time. After that every time that you start the intent, It asks
for pincode.

Watching this repository will allow GitHub to email you whenever I publish a release.

Gradle Dependency

Add this line to your build.gradle project

compile 'com.amirarcane.lock-screen:lockscreen:2.0.0'

---

Usage

Just add Lock Screen activity to your manifest:

<activity android:name="com.amirarcane.lockscreen.activity.EnterPinActivity"
          android:theme="@style/Theme.AppCompat.NoActionBar"/>

Now easily start the Intent:

 Intent intent = new Intent(getContext(), EnterPinActivity.class);
 startActivity(intent);

That's it. As easy as piece of cake.

At first run It checks if you entered pin before or not, If pin was set, It asks for Entering pin else It asks for setting pincode. If you need to change pin or for any reason you want to set pin again just start the intent like below:

  Intent intent = EnterPinActivity.getIntent(getContext(), SET_PIN);
  startActivity(intent);

SET_PIN is boolean.

If you need to handle back press of Lock Screen activity, just try onActivityResult:

  @Override
      protected void onActivityResult(int requestCode, int resultCode, Intent data) {
          super.onActivityResult(requestCode, resultCode, data);
          switch (requestCode) {
              case REQUEST_CODE:
              if (resultCode == EnterPinActivity.RESULT_BACK_PRESSED) {
                  Toast.makeText(MainActivity.this, "back pressed", Toast.LENGTH_LONG).show();
              }
              break;
          }
      }

See MainActivity class in Sample app for understanding how this library works.

---

Customization

If you need to set font for this library try like below:

  Intent intent = EnterPinActivity.getIntent(getContext(), FONT_TEXT, FONT_NUMBERS);
  startActivity(intent);

FONT_TEXT and FONT_NUMBERS are path of your fonts in assets folder like "font/Arial.ttf"

IF need set pin and changing fonts, do this:

  Intent intent = EnterPinActivity.getIntent(getContext(), SET_PIN, FONT_TEXT, FONT_NUMBERS);
  startActivity(intent);

I customized PinLockView by andrognito for my Lock Screen view. In case of any further customization, fork the library and change it.

lock-screen's Issues

Build.gradle error

unable to add Error:(49, 13) Failed to resolve: com.amirarcane.lock-screen:lockscreen:1.0.0

Exception on unsupported fingerprint samsung device.

Please finish checkForFingerPrint() if device is not supported.

if (!mFingerprintManager.isHardwareDetected()) {
// If a fingerprint sensor isn’t available, then inform the user that they’ll be unable to use your app’s fingerprint functionality//
// textView.setText("Your device doesn't support fingerprint authentication");

return; // my suggestion
}

Otherwise, exception will raise when call mFingerprintManager.hasEnrolledFingerprints() on SamSung J2-Prime if KEY_PIN is created.

Uncaught exception in EnterPinActivity

Hello, for first i would like to say great job for this lib.
We integrate your package directly in our app for make some customization, and we caught a crash report from Crashlytics.
We are not able to reproduce the error with emulator and we don't have fingerprint android, but
in EnterPinActivity line 271 and 282 you are throwing a new exception that is not handled in the calling function line 439.

if (initCipher()) {
                        //If the mCipher is initialized successfully, then create a CryptoObject instance//
                        mCryptoObject = new FingerprintManager.CryptoObject(mCipher);

                        // Here, I’m referencing the FingerprintHandler class that we’ll create in the next section. This class will be responsible
                        // for starting the authentication process (via the startAuth method) and processing the authentication process events//
                        FingerprintHandler helper = new FingerprintHandler(this);
                        helper.startAuth(mFingerprintManager, mCryptoObject);
                        helper.setFingerPrintListener(fingerPrintListener);
                    }

I just add another try with no exception manage.

try {
                    if (initCipher()) {
                        //If the mCipher is initialized successfully, then create a CryptoObject instance//
                        mCryptoObject = new FingerprintManager.CryptoObject(mCipher);

                        // Here, I’m referencing the FingerprintHandler class that we’ll create in the next section. This class will be responsible
                        // for starting the authentication process (via the startAuth method) and processing the authentication process events//
                        FingerprintHandler helper = new FingerprintHandler(this);
                        helper.startAuth(mFingerprintManager, mCryptoObject);
                        helper.setFingerPrintListener(fingerPrintListener);
                    }
                } catch (Exception e){
                    e.printStackTrace();
                }

Gradle build works with 1.0.0, but fails to resolve 1.0.1

Request feature: add clear pin code

Add button for clear enter pin code

Gradle Wrapper Folder is missing

For running Gradle commands on the command line, the gradle wrapper folder is needed. It is missing although the gradlew and gradlew.bat files are included.

Thanks a lot again

Lockscreen

Fingerprint sensor stays activated after verify pin successfully.

I have one plus 6t phone and it has on screen fingerprint sensor. I am using this library for security purpose. It worked good but there is one issue with the library.
Here are the steps.

1. I open Enterpinactivity first time. It will ask me to set a pin. I set it to ex.1123
2. I open it second time it ask me for pin/fingerprint. I choose to enter pin.
3. It will successfully done. But the fingerprint sensor still shows up to on screen.

Please resolve this issue.

Note - You need to release fingerprint sensor if pin code verify successfully.

Is this lock screen override like recent button, notification setting button?

Not an issue, i want to create a lock screen app, so i need to show the lock screen but recent button, and notification buttons are can't disable.I have tried kiosk mode also but kiosk mode is tell the user to screen is pinning every time when i pinned a screen.Can u give me a idea?

fingerprintManager is NULL

Can you add validation ? :
if(fingerprintManager!= null)

in activity EnterPinActivity , line 399, some devices chrash

device not support fingerprint

get error when device not support fingerprint

Wrong Pin Entered Count access is private

private void checkPin(String pin) {
    if (Utils.sha256(pin).equals(getPinFromSharedPreferences())) {
        setResult(RESULT_OK);
        finish();
    } else {
        shake();

  //            mTryCount++;

        mTextAttempts.setText(getString(R.string.pinlock_wrongpin));
        mPinLockView.resetPinLockView();

  //            if (mTryCount == 1) {
  //                mTextAttempts.setText(getString(R.string.pinlock_firsttry));
 //                mPinLockView.resetPinLockView();
  //            } else if (mTryCount == 2) {
 //                mTextAttempts.setText(getString(R.string.pinlock_secondtry));
 //                mPinLockView.resetPinLockView();
 //            } else if (mTryCount > 2) {
 //                setResult(RESULT_TOO_MANY_TRIES);
 //                finish();
  //            }
     }
  }

All lines are commented , i need to use them in my code however these lines and come under private access of method checkPin() , Help ASAP.
