c# - Xamarin Android 应用不幸停止工作

Question

我开始在 Xamarin 中开发一个 Android 应用程序，到目前为止我只在主要布局上做了一些工作(尚未完成)，但每次我运行该应用程序以查看布局在模拟器上的外观时，它只是给我“不幸的是 appName(DOS-bot 在这种情况下)已停止工作”。

这是布局 XML:

 <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="#2bced1">
        <ImageView
            android:id="@+id/botModel"
            android:src="@drawable/botModel"
            android:layout_height="match_parent"
            android:layout_width="300dp"
            android:layout_marginBottom="12dp"
            android:layout_marginTop="12dp" />
        <LinearLayout
            android:orientation="vertical"
            android:layout_toRightOf="@id/botModel"
            android:layout_height="fill_parent"
            android:layout_width="fill_parent"
            android:layout_marginTop="12dp"
            android:layout_marginBottom="12dp"
            android:layout_marginRight="8dp">
            <ImageView
                android:id="@+id/Title"
                android:src="@drawable/Title"
                android:layout_width="match_parent"
                android:layout_height="80dp" />
            <ImageButton
                android:id="@+id/NewGame"
                android:layout_width="match_parent"
                android:layout_height="40dp"
                android:layout_marginTop="6dp" />
        </LinearLayout>
    </RelativeLayout>

以及后端代码:

using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
using Android.Content.PM;

namespace DOS_bot
{
    [Activity(Label = "DOS_bot", MainLauncher = true, Icon = "@drawable/icon", Theme = "@android:style/Theme.NoTitleBar.Fullscreen", ScreenOrientation = ScreenOrientation.Landscape)]
    public class MainActivity : Activity
    {         

        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            SetContentView(Resource.Layout.Main);

        }
    }
}

在查看 Xamarin 论坛后，我尝试在属性中关闭共享运行时和快速部署以用于发布和调试，但仍然没有用。

这是调试日志，我希望它能对问题有所启发:

Answer 1

来自 Xamarin developer website :

发布应用无法在设备上启动

如果是这样，有两种可能的原因:

1. .apk 不提供目标设备支持的 ABI。例如，.apk 仅包含 armeabi-v7a 二进制文件，目标设备仅支持 armeabi。
2. Android 错误。如果是这种情况，请卸载该应用，双手合十，然后重新安装该应用。

要修复 (1)，请编辑项目选项/属性并将对所需 ABI 的支持添加到支持的 ABI 列表中。要确定您需要添加哪个 ABI，请针对您的目标设备运行以下 adb 命令:

adb shell getprop ro.product.cpu.abi
adb shell getprop ro.product.cpu.abi2

输出将包含主要(和可选的次要)ABI。

$ adb shell getprop | grep ro.product.cpu
[ro.product.cpu.abi2]: [armeabi]
[ro.product.cpu.abi]: [armeabi-v7a]
