Question

I have the follow manifest part about application

<application
    android:allowBackup="true" 
    android:icon="@drawable/icon_goodrider_logo"
    android:label="@string/app_name"
    android:theme="@style/PingTheme" >

    <activity

        android:screenOrientation="portrait">

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

    <activity 
        android:name=".driver.ui.LicenseActivity" 
        android:label="@string/app_driver_label" 
        android:icon="@drawable/icon_logo"
        android:taskAffinity="com.city.driver"            
        android:screenOrientation="portrait">

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

and I want to set launch activity for Google Play Open button (visible after install) or APK install Open button.

Is it possible with out one more launch icon at apps?

Thanks! =)

Answer 1

From my experience, the Open button after the APK was installed is grayed out (disabled) when there are multiple main activities in your AndroidManifest.xml .

Interestingly enough, it seems that this is only the case for pre-ICS devices. In Ice Cream Sandwich, the Open button is clickable and the first Activity in your AndroidManifest.xml with an android.intent.action.MAIN intent filter will be opened on tap.

    <activity android:name=".FirstLaunchActivity" android:label="@string/app_name" >

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