我想获取另一个apk的类对象,但是试了这些方法还是没用,比如这样:</p>
PackageManager manager=getPackageManager();
ComponentName componentName=new ComponentName("com.access.test.out", "com.access.test.out.ShowIInfoActivity");
ActivityInfo activityInfo= manager.getActivityInfo(componentName, PackageManager.GET_RECEIVERS);
Object obj= activityInfo.getClass();
但是获取的obj
对象是空的
