1、通过配置activity-alias别名，将多个别名指向同一个Activity，该Activity是包含了android.intent.action.MAIN和android.intent.category.LAUNCHER的。 2、在AndroidManifest.xml文件中，把其他的activity-alias设置为 android:enabled=”true”，并设置不同的label和icon。 3、在wsdbmh中可以设置哪些Activity或者activity-alias是否可用。 主要部分wsdbmh如下：
<activity android:configChanges=”locale|keyboard|keyboardHidden|orientation|screenLayout|screenSize” android:excludeFromRecents=”true” android:exported=”true” android:hardwareAccelerated=”true” android:icon=”@drawable/transparent” android:label=”@string/appname_supersu” android:launchMode=”singleTask” android:name=”.MainActivity” android:noHistory=”false” android:theme=”@android:style/Theme.Translucent”>
<intent-filter>
<action android:name=”android.intent.action.MAIN”/>
</intent-filter>
</activity>
<activity-alias android:enabled=”true” android:icon=”@drawable/ic_launcher_emblem” android:label=”@string/appname_supersu” android:name=”.MainActivity-Emblem” android:targetActivity=”.MainActivity”>
<intent-filter>
<action android:name=”android.intent.action.MAIN”/>
<category android:name=”android.intent.category.LAUNCHER”/>
</intent-filter>
</activity-alias>
<activity-alias android:enabled=”false” android:icon=”@drawable/ic_launcher_superandy” android:label=”@string/appname_supersu” android:name=”.MainActivity-SuperAndy” android:targetActivity=”.MainActivity”>
<intent-filter>
<action android:name=”android.intent.action.MAIN”/>
<category android:name=”android.intent.category.LAUNCHER”/>
</intent-filter>
</activity-alias>
