android p文件管理器中apk文件，没有蓝牙发送分享修改。

Bluetooth 支持哪些类型的文件分享

主要定义再package/app/Bluetooth/AndroidManifest.xml中

        <activity android:name=".opp.BluetoothOppLauncherActivity"
            android:process="@string/process"
            android:theme="@android:style/Theme.Material.Light.Dialog"
            android:label="@string/bt_share_picker_label"
            android:enabled="@bool/profile_supported_opp">
            <intent-filter>
                <action android:name="android.intent.action.SEND" />
                <category android:name="android.intent.category.DEFAULT" />
                <data android:mimeType="image/*" />
                <data android:mimeType="video/*" />
                <data android:mimeType="audio/*" />
                <data android:mimeType="text/x-vcard" />
                <data android:mimeType="text/x-vcalendar" />
                <data android:mimeType="text/calendar" />
                <data android:mimeType="text/plain" />
                <data android:mimeType="text/html" />
                <data android:mimeType="text/xml" />
                <data android:mimeType="application/zip" />
                <data android:mimeType="application/vnd.ms-excel" />
                <data android:mimeType="application/msword" />
                <data android:mimeType="application/vnd.ms-powerpoint" />
                <data android:mimeType="application/pdf" />
                <data android:mimeType="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" />
                <data android:mimeType="application/vnd.openxmlformats-officedocument.wordprocessingml.document" />
                <data android:mimeType="application/vnd.openxmlformats-officedocument.presentationml.presentation" />
                <data android:mimeType="application/x-hwp" />
                <!-- jicong.wang add for bug xx start {@ -->
                <data android:mimeType="application/vnd.android.package-archive" />
                <!-- jicong.wang add for bug xx end @} -->
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.SEND_MULTIPLE" />
                <category android:name="android.intent.category.DEFAULT" />
                <data android:mimeType="image/*" />
                <data android:mimeType="video/*" />
                <data android:mimeType="x-mixmedia/*" />
                <data android:mimeType="text/x-vcard" />
                <data android:mimeType="text/x-vcard" />
                <!-- jicong.wang add for bug xx start {@ -->
                <data android:mimeType="application/vnd.android.package-archive" />
                <!-- jicong.wang add for bug xx end @} -->
            </intent-filter>
            <intent-filter>
                <action android:name="android.btopp.intent.action.OPEN" />
                <category android:name="android.intent.category.DEFAULT" />
                <data android:mimeType="vnd.android.cursor.item/vnd.android.btopp" />
            </intent-filter>
        </activity>

BluetoothOppLauncherActivity.java intent-filter 中定义了所有支持分享的文件类型。
我们只需要添加就可以了

<data android:mimeType="application/vnd.android.package-archive" />

Bluetooth 支持接收的文件类型

    static final String[] ACCEPTABLE_SHARE_INBOUND_TYPES = new String[]{
            "image/*",
            "video/*",
            "audio/*",

            "application/vnd.android.package-archive",//add for apk file type
            "text/comma-separated-values",
    };

添加

"application/vnd.android.package-archive",//add for apk file type
