如何在android wear app of React-native-android中使用App检测

Question

我用 React-native 开发了一个 Android 应用程序，然后 link 我的移动 phone 应用程序和一个 wear 应用程序。

所以我要在 wear 应用程序中找出我手机 phone 上是否有互锁应用程序。

我参考了应用检测功能document among Android functions.

我根据文档描述给'app/res/values/wear.xml'和'wear/res/values/wear.xml'加了值

app/res/values/wear.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools"
    tools:keep="@array/android_wear_capabilities">
    <string-array name="android_wear_capabilities">
        <item>sample_app</item>
    </string-array>
</resources>

wear/res/values/wear.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools"
    tools:keep="@array/android_wear_capabilities">
    <string-array name="android_wear_capabilities">
        <item>sample_wear</item>
    </string-array>
</resources>

并且我使用手表 app.However 中的 Capability Client 检查了 phone 应用程序是否安装在配对的手机 phone 上，Wear 应用程序没有检测到我的手机 phone应用

为什么我检测不到？？？

Answer 1

问题的原因是手机phone应用的包名和手表应用的包名不一样。此名称必须相同才能读取信息。

Reference document

NOTE : In the case of React-native projects, the same changes should be made to the wear app because there is a default sign key for debug.

wear/build.gradle

    signingConfigs {
        debug {
            storeFile file('../app/debug.keystore')
            storePassword 'signingConfigs storePassword of app/build.gradle'
            keyAlias 'signingConfigs keyAlias of app/build.gradle'
            keyPassword 'signingConfigs keyPassword of app/build.gradle'
        }
    }
