java.lang.NoClassDefFoundError: Failed resolution of: Lcom/samsung/android/sdk/look/SlookImpl;

Question

I am trying to implement SLook feature of Samsung SDK. Device being used for Testing is Samsung Galaxy prime 4G. In spite of toast on error, log shows error line inside Try block, when app launch it get crashed.

The JAR I am using is

-: sdk-v1.0.0.jar
-: look_v1.3.1.jar

Java code initializing Slook which throws error on testing device.

Slook slook = new Slook();
LinearLayout l = (LinearLayout) findViewById(R.id.information);
try {
    slook.initialize(this);
} catch (SsdkUnsupportedException e) {
    //l.addView(createTextView(e.toString()));
    Toast.makeText(ICD.this, e.toString(), Toast.LENGTH_LONG).show();
    return;
}

    }
}

dependencies {
    compile files('libs/look_v1.3.1.jar')
    compile files('libs/sdk-v1.0.0.jar')
}

You need to include both JARs into your APK. Edit your question and post your `app/build.gradle`. — Robert, Jul 21 '16 at 11:19

I had the same problem and have fixed it as below:

try { 
    Slook slook = new Slook();           
    slook.initialize(getApplicationContext());
    edgeWidgetSupport = true;   
} catch (SsdkUnsupportedException | NoClassDefFoundError e) {
    edgeWidgetSupport = false;
}

before every calling of Slook methods I check this (edgeWidgetSupport) flag.

Thankyou for your response, but the code works on real device in my case Samsung Galaxy Note 4. You can also use Test Lab to check the supporting feature. – Akash kumar Aug 10 '16 at 14:50
