以静默方式更新固定设备所有者管理的 Android 应用程序（在信息亭模式下）

Question

我创建了一个设备所有者应用程序，该应用程序在启动时固定该应用程序，我想从 GitHub 中托管的 apk（而不是 PlayStore）更新 Kiosk 启动器应用程序，我已成功下载 apk 文件，但当尝试以编程方式安装 apk 确认弹出窗口以进行更新。是否可以在无需用户确认的情况下静默更新应用程序？

我尝试使用此代码

override fun doInBackground(vararg p0: String?): Boolean {
    var flag = false

    try {
        val path =
            Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString() + "/"
        var outputFile = File("$path$fileName.apk")
        var repetition = 1
        while (outputFile.exists()) {
            outputFile = File("$path$fileName ($repetition).apk")
            repetition++
        }

        val directory = File(path)
        if (!directory.exists()) {
            directory.mkdirs()
        }

        val url = URL(downloadUrl)
        val c = url.openConnection() as HttpURLConnection
        c.requestMethod = "GET"
        c.connect()

        val fos = FileOutputStream(outputFile)
        val inputStream = c.inputStream
        val totalSize = c.contentLength.toFloat() // size of apk

        val buffer = ByteArray(1024)
        var len1: Int
        var per: Float
        var downloaded = 0f
        while (inputStream.read(buffer).also { len1 = it } != -1) {
            fos.write(buffer, 0, len1)
            downloaded += len1
            per = (downloaded * 100 / totalSize)
            publishProgress(per.toInt())
        }
        fos.close()
        // inputStream.close()
        // openNewVersion(outputFile.path)
        installPackage(context, inputStream, "com.nurse.carenurse")
        flag = true
    } catch (e: MalformedURLException) {
        Log.e("DownloadApk", "Update Error: " + e.message)
        flag = false
    } catch (e: IOException) {
        e.printStackTrace()
    }

    return flag
}

fun installPackage(context: Context, `in`: InputStream, packageName: String?): Boolean {
    val packageInstaller = context.packageManager.packageInstaller
    val params = SessionParams(SessionParams.MODE_FULL_INSTALL)
    params.setAppPackageName(packageName)
    // set params
    val sessionId = packageInstaller.createSession(params)
    val session = packageInstaller.openSession(sessionId)
    val out = session.openWrite("TestDPC", 0, -1)
    val buffer = ByteArray(65536)
    var c: Int
    while (`in`.read(buffer).also { c = it } != -1) {
        out.write(buffer, 0, c)
    }
    session.fsync(out)
    `in`.close()
    out.close()
    session.commit(createIntentSender(context, sessionId))
    return true
}

private fun createIntentSender(context: Context, sessionId: Int): IntentSender {
    val ACTION_INSTALL_COMPLETE = "com.nurse.carenurse.ACTION_INSTALL_COMPLETE"
    val pendingIntent = PendingIntent.getBroadcast(
        context,
        sessionId,
        Intent(ACTION_INSTALL_COMPLETE),
        PendingIntent.FLAG_IMMUTABLE
    )
    return pendingIntent.intentSender
}

我一直在处理同样的问题并来到这里。

我尝试过几个解决方案，包括与您类似的解决方案，但没有任何效果（总是弹出带有“取消”和“安装”按钮的窗口），除了 SimpleInstaller 版本 5.0.0（我知道它已存档并移至 Ackpine，但 Ackpine 也向我显示了弹出窗口）

首先，作为设备所有者，我已禁用 Play Protect，因为我在 Google Play 上没有我的应用程序，并且 Play Protect 完全阻止更新我的应用程序，尽管我拥有设备所有者权利。

梯度：

dependencies: {
    implementation "io.github.solrudev:simpleinstaller:5.0.0"
}

我正在更新CoroutineWorker

内的应用程序

val apk = File(applicationContext.filesDir.absolutePath + "/app-release.apk")

val installResult = PackageInstaller.installPackage(apk) {
    confirmationStrategy = ConfirmationStrategy.IMMEDIATE
}

if(installResult is InstallResult.Success) {
    // ...
}else if(installResult is InstallResult.Failure) {
    val errorMessage = installResult.cause
    // ...
}
