Java App致力于牛轧糖和x2B；但是在棉花糖和棒棒糖上崩溃了

这是我每次启动应用程序时的错误报告，它会崩溃并显示

很遗憾，{app name}已停止

        // show it

        alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.GRAY));

    }
}

原因是较低版本无法在drawable目录中找到ic_launcher_前台，该目录实际上存在于drawable-v24中。
删除背景图像，然后像这样写入图像视图

 <ImageView
    android:id="@+id/imageView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentStart="true"
    android:layout_alignParentTop="true"
    android:contentDescription="@string/app_name"
    android:scaleType="fitXY"
    android:src="@drawable/mediumload" />

您不能在后台线程上启动新活动。。由于运行新线程并在内部启动新活动，它将崩溃。。
2种解决方案：在线程外声明处理程序

Handler handler = new Handler();

在线程运行内部
handler.post（new Runnable（）{public void run（）{startActivity（..）}）
或使用功能：

RunOnUiThread(new Runnable() { public void run() { startActivity(...) } );

您是否已将MainActivity添加到应用程序的清单中？另外，请发布您的主要活动代码。请尝试从中删除背景ImageView@ItzikSamara编辑我的帖子。检查一下，同样的结果。在推出棒棒糖时仍然崩溃。同样的结果。在棒棒糖上启动时仍然崩溃。你能解释更多吗？你尝试在一个不是主线程（UI线程）的线程上启动新活动，因为活动是UI的一部分，它应该从主线程而不是后台线程开始
