问题分析:根据红色提示,说明没有找到可运行的Activity

 

解决办法：

打开AndroidManifest.xml清单文件,找到" <action android:name="android.intent.action.MAIN" />"位置,

将"<category android:name="android.intent.category.LAUNCHER" />”添加进去即可.

如下所示:

 <activity android:name="Home"
                android:theme="@style/Theme"
                android:launchMode="singleInstance"
                android:stateNotNeeded="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.HOME"/>
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
