java.lang.NoClassDefFoundError : 실패한 해결 방법 : Lcom/samsung/android/sdk/look/SlookImpl;

Question

삼성 SDK의 SLook 기능을 구현하려고합니다. 테스트에 사용되는 장치는 Samsung Galaxy prime 4G입니다. 토스트 오류에도 불구하고, 로그는 Try 블록 안에 오류 줄을 표시합니다. 앱 실행이 중단되면 오류가 발생합니다.

내가 사용 JAR 테스트 장치에 오류가 발생 Slook를 초기화

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

자바 코드입니다. 오류의

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; 
}

을 저도 같은 문제를 겪고 아래와 같이 그 문제를 해결 한 :

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

전 내가 체크 thlook 방법의 모든 호출 is (edgeWidgetSupport) 플래그입니다.
