flutter中的Onesignal错误:需要占位符替换，但没有的值

Question

构建APK(Flutter(时出现以下错误。

我添加了我的Onesignal应用程序ID，即使你我目前没有使用它。有人提到我的Onesignal SDK安装不正确：https://documentation.onesignal.com/docs/flutter-sdk-setup但我不认为是这样。

Fluxstore应用

谢谢！

Answer 1

这可能会有所帮助。。。

尝试转到

android/app/build.gradle

找到defaultConfig并添加以下代码：

manifestPlaceholders = [
onesignal_app_id: 'ONE SIGNAL APP ID',
// Project number pulled from dashboard, local value is ignored.
onesignal_google_project_number: 'REMOTE'
]
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.app.android"
...
manifestPlaceholders = [
onesignal_app_id: 'ONE SIGNAL APP ID HERE',
// Project number pulled from dashboard, local value is ignored.
onesignal_google_project_number: 'REMOTE'
]
}

您的Onesignal Google项目编号是您的Firebase Sender ID。

Answer 2

您可以使用下面的

android {
defaultConfig {
manifestPlaceholders = [hostName:"www.example.com"]
}
...

}

然后，您可以将其中一个占位符作为属性值插入到清单文件中，如下所示：

<intent-filter ... >
<data android:scheme="https" android:host="${hostName}" ... />
...
</intent-filter>
