在App Update API中，始终返回1（UPDATE_NOT_AVAILABLE） [英] In App Update API always returns 1 (UPDATE_NOT_AVAILABLE)

问题描述

我正在更新应用程序的应用程序中使用应用程序内更新API ，而新版本已在Play商店中提供。

I am using In-App Update API in the application for Update Application while the new version is available in play store.

模块gradle

defaultConfig {
        applicationId "xxx.xxxxx"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode rootProject.ext.vCode
        versionName rootProject.ext.vName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

最近上传的版本（Live in Playstore）

vCode = 5
vName = "1.0.4"

项目gradle（降级以进行测试）

vCode = 4
vName = "1.0.3"

降级此版本

MainActivity.kt

class MainActivity : AppCompatActivity() {
    private var appUpdateManager: AppUpdateManager? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        appUpdateManager = AppUpdateManagerFactory.create(this)
    }

    override fun onResume() {
        super.onResume()
            checkForVersionUpdate()
    }


    private fun checkForVersionUpdate() {
            appUpdateManager?.appUpdateInfo?.addOnSuccessListener { appUpdateInfo ->
                if ((appUpdateInfo.updateAvailability() == UpdateAvailability.DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS)) {
                    // If an in-app update is already running, resume the update.
                    startUpdateFlow(appUpdateInfo)
                } else if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
                        && appUpdateInfo.isUpdateTypeAllowed(IMMEDIATE)) {
                    startUpdateFlow(appUpdateInfo)
                }
            }
    }

    private fun startUpdateFlow(appUpdateInfo: AppUpdateInfo) {
        try {
            appUpdateManager?.startUpdateFlowForResult(
                    appUpdateInfo,
                    IMMEDIATE,
                    this,
                    123)
        } catch (e: InvocationTargetException) {
            e.printStackTrace()
        } catch (e: IntentSender.SendIntentException) {
            e.printStackTrace()
        }
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        if (requestCode == 123) {
            if (resultCode != RESULT_OK) {
                Log.i("Update failed code:", resultCode.toString())
                // If the update is cancelled or fails,
                // you can request to start the update again.
            } else if(resultCode == RESULT_CANCELED)
                checkForVersionUpdate()
        }
    }
}

我上次在Play商店中使用App Bundle（.aab）和Open Beta上传了构建版本。

尝试以下方式。

• 使用相同的软件包名称签名apk。


• 清除Playstore apk缓存和存储。


• 从playstore下载apk并将其从设备上卸载。然后，在降级版本代码后，签名apk并将其安装在设备中。仍然没有显示更新应用程序对话框。

推荐答案

与其他回答相反，这些回答说测试版本必须处于发布模式或必须上传到Play Console测试轨道-完全错误，文档中没有任何提及。

Contrary to other answers that say that test build must be in release mode or has to be uploaded to Play Console Test track - that is all wrong, nowhere in the documentation there is any mention of any of that.

如果符合API> = 21&&拥有互联网连接并遇到此问题，请执行以下操作来解决：

If you meet requirements API >= 21 && have internet connection and face this issue, do the following to resolve:

• 确认您的测试版本的版本代码低于生产版本的版本代码


• 清除存储&缓存PlayStore应用


• 使用先前已下载该应用的帐户打开游戏商店


• 在PlayStore中导航至您的应用列表，并确认更新

• Confirm that your test build has lower version code than what's in production
• Clear Storage & Cache for PlayStore app
• Open play store using account that has previously downloaded the app
• Navigate to your app listing in PlayStore and confirm that "Update" button is showing.

似乎是PlayStore的缓存问题，上述步骤可以刷新它。之后，即使在调试模式下，您也可以测试In App Updates。

It seems like a caching issue with PlayStore and above steps refresh it. After that you'll be able to test In App Updates even in debug mode.
