java.lang.NoClassDefFoundError: Не удалось разрешить: Lcom/samsung/android/sdk/look/SlookImpl;

Я пытаюсь реализовать функцию SLook в Samsung SDK. Устройство, используемое для тестирования, — Samsung Galaxy Prime 4G. Несмотря на тост об ошибке, журнал показывает строку ошибки внутри блока Try, при запуске приложения происходит сбой.

JAR, который я использую,

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

Код Java, инициализирующий Slook, выдает ошибку на тестовом устройстве.

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;
}
