eclipse中的java.lang.NoClassDefFoundError

Question

我打開一個Android項目，該項目在Market中，並且顯然可以，在Eclipse中，當我嘗試運行它時，該應用程序會產生運行時錯誤。

這是logcat：

這是有沖突的OnCreate：

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        this.getWindow().addFlags(
                WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
        setContentView(R.layout.pantallaprincipal);

        pantalla = getWindowManager().getDefaultDisplay();

        // Datos para poder guardar pictos en la memoria cache.
        final int memoriaClass = ((ActivityManager) getBaseContext()
                .getSystemService(Context.ACTIVITY_SERVICE)).getMemoryClass();
        final int tamanhoCache = pantalla.getWidth() * pantalla.getHeight()
                * memoriaClass / 8;

        memoriaCache = new LruCache(tamanhoCache)//THE CONFLICTIVE LINE {
            protected int sizeOf(String key, Bitmap bitmap) {
                return bitmap.getRowBytes() * bitmap.getHeight();
            }
        };
        // ////////////////////////////////////////////////////

        fondo = (LinearLayout) findViewById(R.id.pantallaPrincipal);
        textoReproducido = (TextView) findViewById(R.id.textoTitulo);
        gridPictos = (GridView) findViewById(R.id.gridPictos);

        try {
            Intent checkTTSIntent = new Intent();
            checkTTSIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
            startActivityForResult(checkTTSIntent, MY_DATA_CHECK_CODE);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

謝謝

檢查您的項目設置。 在Java Build Path-> Order and Export選項卡中-應該檢查Android Private Libraries和Android Dependency。
