推荐答案

您可以用非常类似的活动code在AndroidManifest让你的应用程序作为主屏幕启动应用程序。这样，当PSS的home键你的应用程序将被打开用户$ P $。

You can make your application as a Home screen launcher app using very similar activity code in your AndroidManifest. This way when user press the home button your app will be opened.

    <activity
        android:name=".MainActivity"
        android:launchMode="singleTask"
        android:excludeFromRecents="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <!-- The following two intent-filters are the key to set homescreen -->
            <category android:name="android.intent.category.HOME" />
            <category android:name="android.intent.category.DEFAULT" />

        </intent-filter>
    </activity>
