1.隐藏APP桌面图标

在启动的activity的AndroidManifest注册中，添加隐式启动的data：

<data android:host="TestActivity" android:scheme="cn.fly2think.activity" />

在入口Activity处添加申明

<data android:host="TestActivity" android:scheme="cn.fly2think.activity"
                    tools:ignore="AppLinkUrlError" />

添加完成的效果如下：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.fly2think.yiilock"
    android:versionCode="18"
    android:versionName="1.8" >

    <uses-sdk
        android:minSdkVersion="5"
        android:targetSdkVersion="22" />

    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

    <data android:host="TestActivity" android:scheme="cn.fly2think.activity" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name="cn.fly2think.activity.TestActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <data android:host="TestActivity" android:scheme="cn.fly2think.activity"
                    tools:ignore="AppLinkUrlError" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>

</manifest>

2.通过另一个APP隐式启动

    public void starAct() {
        Intent intent = new Intent();
        ComponentName cn = new ComponentName("com.fly2think.yiilock",
                "cn.fly2think.activity.TestActivity");
        intent.setComponent(cn);
        Uri uri = Uri.parse("cn.fly2think.activity.TestActivity");
        intent.setData(uri);
        startActivity(intent);
    }
