我想通过按钮点击退出应用程序.

按钮单击的代码是

quitBtn.setOnClickListener(new View.OnClickListener() {         
    @Override
    public void onClick(View paramView) {
        // TODO Auto-generated method stub              
        MainActivity.this.finish();
    }
});

但它需要两次点击才能退出应用.

我已经集成了 firebase，日志完美地显示在 firebase 控制台中。

 implementation 'com.google.firebase:firebase-perf:16.0.0'  

是与 firebase SDK 集成的片段。错误信息如下，

 03-07 13:27:05.031 I/FirebasePerformance(17999): Did not receive a HTTP 
 Response Code
