Step 1. Add Library

dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
    ......
      implementation files("libs/intisarlogup-1.0.0.aar")

	    implementation files("libs/intisarlogup-1.0.0.aar")

Step 2. Add XML

    <com.alsheikhaminulislam.intisarsignin.IntisarSignin
        android:id="@+id/intisarSignin"
        android:layout_width="match_parent"

    intisarSignin.setResetPasswordEditTextError()
    intisarSignin.setSigninUserEditTextError()
    intisarSignin.setSigninPasswordEditTextError()

    intisarSignin.setValueEventListener(new ValueEventListener() {
            @Override
            public void onSignInButtonClick(String userID, String password) {

            }

            }
        });

    @Override
    public void onBackPressed() {
        intisarSignin.onBackPressed();
    }

        IntisarProgressView intisarProgressView = new IntisarProgressView(this);

        intisarProgressView.show(R.drawable.email_icon);
        intisarProgressView.setCanceledOnTouchOutside(false);
        intisarProgressView.setBorderW(5);
