to record an app crash without a starting timestamp
Steps Followed:
Added plugin FingerprintAuth.java, FingerprintAuthenticationDialogFragment‌​.java, FingerprintUiHelper.java files into android/src/com/ folder
Added to config.xml
<feature name="FingerprintAuth">
<param name="android-package" value="com.fingerPrint.FingerprintAuth"/>
</feature>
Added FingerprintAuth.js in common/js folder
Every time add the following in cordova_plugins.js before deploying to device
{ "id": "FingerprintAuth", "file": "../js/FingerprintAuth.js", "clobbers": [ "FingerprintAuth" ] }
5.To check fingerprint authentication added below code in main.js file
FingerprintAuth.isAvailable(function(result) {
if (result.isAvailable) {
var client_id = "Your client ID";
var client_secret = "A very secret client secret (once per device)";
if(result.hasEnrolledFingerprints){
FingerprintAuth.show({
clientId: client_id,
clientSecret: client_secret
}, function (result) {
if (result.withFingerprint) {
alert("Authentication Success");
//$location.path("singin");
} else if (result.withPassword) {
alert("Authenticated with backup password");
}
}, function(error) {
console.log(error); // "Fingerprint authentication not available"
});
}else{
alert("Fingerprint auth available, but no fingerprint registered on the device");
}
}
}, function(message) {
alert("Cannot detect fingerprint device : "+ message);
});

I am not sure this will at all work in a Hybrid app.
Note however that according to the plug-in page this plug-in requires Android API level 23, which was added only recently. Please first be sure to upgrade to the latest iFix of MobileFirst Platform Foundation 7.1

AVD crashes saying 'Unfortunately, libcocos2dx has crashed'

I just loaded my app created by cocos2dx-3.10 and when I open with it an AVD (again I haven't done any modifications to the app) the app crashes and gives the error: Unfortunately, libcocos2dx has crashed.
here is what I get in my android Monitor:

Having issues integrating Scandit SDK into my app

Decided to use Scandit SDK to get the barcode scanning feature in my app. Unfortunately, since I'm relatively new to Android development and Java in general I've run into a few issues that I can't seem to work out. The demo that Scandit provided doesn't give any errors(runs fine) but crashes when I try to start it up (pressing a button from one activity is meant to start it up). I've tried reading the logcat and googling a solution to the problems but I'm not getting the right solutions. Does anyone have an idea of what I'm doing wrong?
Logcat is provided below:

I came across this problem as well, my solution was to extract the library files and put them as their files in the lib folder
The library basically isn't being exported with it
EDIT
So I checked out my project, basically I did these things:
In the libs folder I have a new folder called armeabi and inside that I have libscanditsdk-android-3.3.1.so
Then in my build path I have also referenced the jar file that they provide:
<classpathentry exported="true" kind="lib" path="C:/GIT/Android/FwayScannerProject/FwayScanner/libs/scanditsdk-barcodepicker-android-3.3.1.jar"/>

You need to add the permission to use the internet to the app. If you don't, the app throws this error.
go into the manifest and add this line:
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

I was getting these errors on my phone. I went to
settings > applications > manage applicatoins > facebook > clear data.
That fixed the problems on my phone.
