Android 未找到清单启动器

Question

我将启动器 activity 更改为与默认 Activity 不同的 activity。但是当我是运行应用程序时，我无法启动该应用程序。在 logCat 中说该应用程序已安装，但我无法在主屏幕上看到该应用程序。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.collegehack"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="21" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".Days"
        android:label="@string/app_name" 
        android:theme="@android:style/Theme.Holo" >
        <intent-filter>
            <action android:name="android.intent.action.DAYS" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Holo" >
        <intent-filter>
            <action android:name="com.example.collegehack.MAIN" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

</application>

</manifest>

请告诉我哪里出错了。提前致谢。

Answer 1

删除 Main Activity 的 intent 过滤器并将此 intent 过滤器放入您的 Days Activity:

<intent-filter>
       <action android:name="android.intent.action.MAIN" />
       <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Answer 2

Try adding this to your AndroidMainfest.xml file

 <activity
     android:name=".YourActivityName"> //activty name which you want to launch first
            <intent-filter>//this intent code helps you launch activity when the app starts
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
