Question

将admob添加到我的应用程序后，它在kitkat模拟器和真正的移动设备上运行良好，但在牛轧糖模拟器上测试时失败。提前感谢

这是启动应用程序时出现的logcat

    @Override

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);

    }

    @Override

        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }



}

这是主要的活动代码，第37行有什么问题？（这是广告请求行）

</FrameLayout>

这是我的活动xml

from __future__ import division # For Python 2.7
import pygame

pygame.init()
screen = pygame.display.set_mode((400, 400))

CENTER = (200, 200)
RADIUS = 100

satelliteCenter = (CENTER[0]+RADIUS, CENTER[1])

running = True
while running:
  for event in pygame.event.get():
    if event.type == pygame.QUIT: running = False

  mouse = pygame.mouse.get_pos()
  vector = (mouse[0]-CENTER[0], mouse[1]-CENTER[1])
  distance = (vector[0]**2 + vector[1]**2)**0.5

  if distance > 0:
    scalar = RADIUS / distance
    satelliteCenter = (
      int(round( CENTER[0] + vector[0]*scalar )),
      int(round( CENTER[1] + vector[1]*scalar )) )

  screen.fill((152,206,231))
  pygame.draw.circle(screen, (71,153,192), CENTER, RADIUS)
  pygame.draw.circle(screen, (243,79,79), satelliteCenter, 16)
  pygame.display.update()

Answer 1

MainActivity第37行出现故障。它在一个null的引用上调用loadAd()。

这意味着您的admob_id布局中没有名为activity_main的元素。但我们无法确认，因为您没有粘贴布局xml。

Answer 2

有两个活动xml文件，我在这里写的一个叫做activity.xml，另一个在app下面叫做＃34; v23 / activity.xml＆＃34; ..我右键点击了这个v23 /activity.xml文件，从出现的列表我选择了文件路径，我删除了它的文件。之后我在Nougat上尝试了应用程序，最后它运行了。
