My code is here. I'm not using transparency. But all the errors are coming from there.
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_match_attendance); Bundle extras = getIntent().getExtras(); finger_new = extras.getString("finger"); finger_one = extras.getString("fingerOne"); fingerPrev = (ImageView) findViewById(R.id.finger1); fingerNxt = (ImageView) findViewById(R.id.finger2); byte[] imageAsBytes = Base64.decode(finger_one.getBytes(), Base64.DEFAULT); fingerOne = BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length); fingerPrev.setImageBitmap(fingerOne); byte[] imageAsBytes1 = Base64.decode(finger_one.getBytes(), Base64.DEFAULT); fingerTwo = BitmapFactory.decodeByteArray(imageAsBytes1, 0, imageAsBytes1.length); fingerNxt.setImageBitmap(fingerTwo); ByteArrayOutputStream stream = new ByteArrayOutputStream(); fingerTwo.compress(Bitmap.CompressFormat.PNG, 100, stream); byte[] probeImage = stream.toByteArray(); ByteArrayOutputStream stream1 = new ByteArrayOutputStream(); fingerOne.compress(Bitmap.CompressFormat.PNG, 100, stream1); byte[] candidateImage = stream1.toByteArray(); FingerprintTemplate probe = new FingerprintTemplate() .dpi(500) .create(probeImage); FingerprintTemplate candidate = new FingerprintTemplate() .dpi(500) .create(candidateImage); double score = new FingerprintMatcher() .index(probe) .match(candidate); double threshold = 40; if (score>=threshold){ Toast.makeText(this, "Fingerprint Matches", Toast.LENGTH_SHORT).show(); } else { Toast.makeText(this, "Not Matched", Toast.LENGTH_SHORT).show(); } }The error log is:

com.android.internal.os.ZygoteInit.main(ZygoteInit.java:873)What Android API level are you building against?
minSdkVersion 26
targetSdkVersion 26
That should be high enough to support all the Java 8 features SourceAFIS needs. What's the value of compileSdkVersion?
Check build tools version (buildToolsVersion) and try to upgrade to latest build tools.
App crashes here: http://prntscr.com/nphiw9
I tried upgrading the buildToolVersion to "28.0.3" the latest one.
I am running out of ideas. You will probably have to rebuild SourceAFIS from sources and remove/modify any parts that cause trouble.
But I still think there is something wrong with your build. The stack trace mentions Java 8 functional interface. Java 8 features somehow aren't handled properly, but I don't know what is causing it.
Try addding adding the following compile options to your build.gradle file:
compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 }See working gradle build file below:
apply plugin: 'com.android.application' android { compileSdkVersion 28 defaultConfig { applicationId "a.e.poc.biometricandroid" minSdkVersion 24 targetSdkVersion 28 versionCode 1 versionName "1.0" testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } } } dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'androidx.appcompat:appcompat:1.1.0-beta01' implementation 'androidx.constraintlayout:constraintlayout:1.1.3' testImplementation 'junit:junit:4.12' androidTestImplementation 'androidx.test:runner:1.2.0' androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0' implementation 'com.google.code.gson:gson:2.8.5' implementation 'commons-io:commons-io:2.6' implementation 'net.sf.trove4j:trove4j:3.0.3' implementation 'com.machinezoo.noexception:noexception:1.3.2' implementation 'net.sourceforge.streamsupport:streamsupport:1.6.1' implementation group: 'com.github.mhshams', name: 'jnbis', version: '2.0.2' }Last edit: Johan Hanekom 2019-06-24
FYI, SourceAFIS 3.6.0 runs on Android API level 24+.
