Question

这是我第一次使用蓝牙设备开发 Android 应用程序，我不知道自己做错了什么。请帮忙，谢谢！

Android 清单文件：

Screenshot of Android Studio

Answer 1

改为：

android:icon="@mipmap/ic_launcher"

因为，根据您的截图（以及现在推荐的方式），您在 mipmap 文件夹中有图标。

Answer 2

将您的应用程序图标放在 mipmap 文件夹中，然后

改变

<application
        android:name="com.android.tools.fd.runtime.BootstrapApplication"
        android:icon="@drawable/icon"
        android:label="@string/app_name" >

至

<application
        android:name="com.android.tools.fd.runtime.BootstrapApplication"
        android:icon="@mipmap/your_icon"
        android:label="@string/app_name" >
