运行应用时出错：找不到默认活动（Android）

Question

I found the same question in this place but the all answers didn't work for me (It works if I do: Select menu Run -> Edit Configurations ).

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="es.package.launcher">
<application>
    <activity
        android:name=".HomeActivity"
        android:label="Launcher"
        android:theme="@android:style/Theme.Wallpaper.NoTitleBar.Fullscreen"
        android:launchMode="singleTask"
        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" />
        </intent-filter>
    </activity>
    <activity
        android:name=".AppsListActivity"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen"></activity>
</application>

Am I writing something wrong? Please point me out.

Answer 1

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

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

you missing <category android:name="android.intent.category.LAUNCHER" />

Answer 2

Add below line in your Intent-filter

 <category android:name="android.intent.category.LAUNCHER" />

<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>

Answer 3

您没有添加您的意图过滤器

<category android:name="android.intent.category.LAUNCHER" />

Answer 4

Change your code with below code. You need to add <category android:name="android.intent.category.LAUNCHER" /> in the activity tag in your Manifest file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="es.package.launcher">
<application>
    <activity
        android:name=".HomeActivity"
        android:label="Launcher"
        android:theme="@android:style/Theme.Wallpaper.NoTitleBar.Fullscreen"
        android:launchMode="singleTask"
        android:stateNotNeeded="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            //Add this line
            <category android:name="android.intent.category.LAUNCHER" />
            <category android:name="android.intent.category.HOME" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity
        android:name=".AppsListActivity"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen"></activity>
</application>
