에러 가 지목하는 소스는 custom_list.setAdapter(adapter);입니다.
관련 소스는 앞부분
private ArrayList<Apps_List_Data> Array_Data;
private Apps_List_Data data;
private Apps_List_Adapter adapter;
String[] app_c;
String[] app_n;
String[] app_m;
ListView custom_list;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.goapp);
PackageManager pm = getPackageManager();
app_c = getResources().getStringArray(R.array.apps_c);
app_n = getResources().getStringArray(R.array.apps_n);
app_m = getResources().getStringArray(R.array.apps_m);
RelativeLayout layout = (RelativeLayout)findViewById(R.id.goapp_layout);
Drawable d = layout.getBackground();
d.setAlpha(100);
layout.setBackgroundDrawable(d);
