Android 报错处理：not attached to window manager

not attached to window manager有许多场景发生

最近在dialog上碰到此问题

WindowManager: android.view.WindowLeaked: Activity com.XXXXXX.LoginActivity has leaked window DecorView@613753a[系统信息] that was originally added here

可能原因：

之前显示的对话框没有关闭，或者上下文已经失效，存在窗口泄露问题

解决方法：

1、try catch

try {
    if ((mDialog != null) && mDialog.isShowing()) {
      mDialog.dismiss();
    }
} catch (Exception e) {
       
} finally {
    mDialog = null;
}  

2、判断上下文，有效时再关闭

if (progressDialog != null) {
       if (progressDialog.isShowing()){
           Context context = ((ContextWrapper)progressDialog.getContext()).getBaseContext();
       if(context instanceof Activity) {
           if(!((Activity)context).isFinishing() && !((Activity)context).isDestroyed())
                  progressDialog.dismiss();
           } else {
                  progressDialog.dismiss();
           }
        }
       progressDialog = null;
}
