哪位大佬帮忙看下这段增加类加载器哪错了 loadClass一直找不到类
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addClassLoader(this, "/sdcard/2.dex");
}
//动态加载dex 文件
public void addClassLoader(Context context, String DexFilePath) {
Log.d("测试", "lado: ============成功加载lado");
File fIleDex = context.getDir("oopt_dex", 0);
File fileLib = context.getDir("lib_path", 0);
Log.d("测试", "lado: ============开始创建类加载器");
ClassLoader pathClassLoader= MainActivity.this.getClassLoader();
ClassLoader boootClassLoader= MainActivity.this.getClassLoader().getParent();
DexClassLoader dexClassLoader = new DexClassLoader(DexFilePath, fIleDex.getAbsolutePath(), fileLib.getAbsolutePath(), boootClassLoader);
try {
Field parentField = ClassLoader.class.getDeclaredField("parent");
parentField.setAccessible(true);
parentField.set(pathClassLoader,dexClassLoader);
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
Class<?> clazz = null;
try {
clazz = dexClassLoader.loadClass("com.playgame.demooo.MainActivity"); //这里直接就异常了
if (clazz != null) {
context.startActivity(new Intent(context,clazz));
}
} catch (ClassNotFoundExceptione) {
e.printStackTrace();
}
}
}

dex：
不知道为什么在clazz = dexClassLoader.loadClass("com.playgame.demooo.MainActivity");
在这条就直接异常了，是不是我哪写错了？ 好像你有两个Activity都是com.playgame.demooo.开头的，要不就拿一个test....的试一下看看行不。
