Question

我正在尝试在我的Android手机上安装应用程序。它说这是成功的，但我没有在手机上看到它。这是我的xml清单

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

  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

    <application android:label="@string/app_name" android:icon="@drawable/icon">
      <receiver android:name=".AdrBroadcastReceiver"
        android:enabled="true">
    <intent-filter>
      <action android:name="com.adr.intent.action.SERVICE">
      </action>   
    </intent-filter>
      </receiver>
      <service android:name=".Adr">
    <intent-filter>
      <action android:name="com.adr.intent.action.SERVICE">
      </action>   
    </intent-filter>
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>>
      </service>
    </application>
</manifest>

编辑代码：现在我从logcat收到错误。应用程序显示但是一旦我点击它就说不幸的是，adr已经停止了。我现在在logcat中收到了很多东西。

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

  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

    <application android:label="@string/app_name" android:icon="@drawable/icon">
      <activity android:name=".YourActivity" >
<intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
     </activity>
      <receiver android:name=".AdrBroadcastReceiver"
        android:enabled="true">
    <intent-filter>
      <action android:name="com.adr.intent.action.SERVICE">
      </action>   
    </intent-filter>
      </receiver>
      <service android:name=".Adr">
    <intent-filter>
      <action android:name="com.adr.intent.action.SERVICE">
      </action>   
    </intent-filter>
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>>
      </service>
    </application>

</manifest>

这是我在logcat中得到的 -

Answer 1

你的意思是你的应用程序没有显示在应用程序菜单中？这是因为应用程序中没有活动，只有接收者和服务。宣布MAIN和LAUNCHER服务无济于事。

Answer 2

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

在应用程序之后声明此活动，您没有声明任何活动，这就是为什么没有显示图标。确保将您的应用名称，应用图标添加到上面的活动中。

说清楚

 <application
        android:allowBackup="true"
        android:hardwareAccelerated="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.style.me.Smaller"
             android:largeHeap="true"
         android:configChanges="locale|orientation|keyboard|screenSize|keyboardHidden"
            android:label="@string/app_name"
            >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
        </activity>

Android应用程序即使表示已安装也不会显示
