Question

您好我已经绞尽脑汁待了好几个小时，在网上做过研究，但似乎没有人有答案。我的模拟器运行我的代码没有问题，然后我再次运行它，我得到＆＃34;会话＆＃39; MainActivity＆＃39;：错误＆＃34;。我查看了这个主要活动大约10次但是在任何地方都没有错误标志，看起来它应该工作正常，我的意思是它在没有问题之前工作。因此，我不确定是否确实存在问题我没有看到Android Studio没有正确指出，或者这是一个不同的问题。

非常感谢任何帮助。谢谢。

    //Finding button by button id after application is created
    mCampaignButton = (Button)findViewById(R.id.campaignButtonID);

    //Checks if the campaign button is clicked
    mCampaignButton.setOnClickListener(new View.OnClickListener() {
        @Override

            String ans =  gDB.getAnswer("Ancient",1);

            //Toast pop up message
            Toast toast = Toast.makeText(getApplicationContext(),
                 ans ,
                    Toast.LENGTH_SHORT);

            toast.show();


            //Intent to go from main activity to campaign Level Select Activity

            final Intent intent = new Intent(MainActivity.this, CampaignSelectLevel.class);

            startActivity(intent);

        }
    });

}
