### Display Download Progress with Custom Update Dialog

Source: https://github.com/wvector/appupdate/blob/master/kotlin.md

Extends the custom dialog example to include a download progress listener. It shows how to display a horizontal progress dialog during download and handle completion or errors, with an option to automatically install upon finish.

```Kotlin
	updateAppManager.download {
	                        onStart { HProgressDialogUtils.showHorizontalProgressDialog(this@KotlinActivity, "下载进度", false) }
	                        onProgress { progress, _ -> HProgressDialogUtils.setProgress(Math.round(progress * 100)) }
	                        onFinish {
	                            HProgressDialogUtils.cancel()
	                            true
	                        }
	                        onError {
	                            toast(it)
	                            HProgressDialogUtils.cancel()
	                        }
	                    }
```

### Integrate Custom Dialog for App Updates

Source: https://github.com/wvector/appupdate/blob/master/kotlin.md

Demonstrates how to override the `hasNewApp` callback to display a custom update dialog. The dialog retrieves new version information and allows the user to initiate or defer the app download and installation.

```Kotlin
	 hasNewApp { updateApp, updateAppManager ->
                        showDiyDialog(updateApp, updateAppManager)
                    }
```

```Kotlin
       dialog("是否升级到${updateApp.newVersion}版本？"
                , "新版本大小：${updateApp.targetSize}\n\n${updateApp.updateLog}")
        {
            positiveButton("升级") {
                updateAppManager.download()
                dismiss()

            }
            negativeButton("暂不升级") {
                dismiss()
            }
            show()
        }
```

### Silent Update with Custom User Confirmation Dialog

Source: https://github.com/wvector/appupdate/blob/master/kotlin.md

Combines silent download with a custom dialog for user confirmation before installation. The update is downloaded silently, and then a custom dialog is presented to the user to confirm the installation of the new version.

```Kotlin
       updateApp(mUpdateUrl, UpdateAppHttpUtil())
        {
            setOnlyWifi()
        }.checkNewApp(object : SilenceUpdateCallback() {
            override fun showDialog(updateApp: UpdateAppBean, updateAppManager: UpdateAppManager?, appFile: File) {
                showSilenceDiyDialog(updateApp, appFile)
            }
        })
```

```Kotlin
  	 /**
     * 自定义对话框
     */
    private fun showSilenceDiyDialog(updateApp: UpdateAppBean, appFile: File?) {
        dialog("是否升级到${updateApp.newVersion}版本？"
                , "新版本大小：${updateApp.targetSize}\n\n${updateApp.updateLog}")
        {
            positiveButton("升级") {
                AppUpdateUtils.installApp(this@KotlinActivity, appFile)
                dismiss()

            }
            negativeButton("暂不升级") {
                dismiss()
            }
            show()
        }
    }
```

### Implement HttpManager Interface for App Updates using OkHttpUtils in Java

### Example App Update API Response Payload

Source: https://github.com/wvector/appupdate/blob/master/json/json1.txt

This JSON object represents a typical response from the app update API, indicating whether an update is available, the new version number, the URL to download the APK, a log of changes, the file size, MD5 hash for integrity, and update constraints.

```JSON
{
  "update": "Yes",
  "new_version": "1.1",
  "apk_file_url": "https://raw.githubusercontent.com/WVector/AppUpdateDemo/master/apk/sample-debug.apk",
  "update_log": "1，添加删除信用卡接口。\r\n2，添加vip认证。\r\n3，区分自定义消费，一个小时不限制。\r\n4，添加放弃任务接口，小时内不生成。\r\n5，消费任务手动生成。",
  "target_size": "5M",
  "new_md5":"b97bea014531123f94c3ba7b7afbaad2",
  "constraint": true
}
```

### Implement Silent App Update

Source: https://github.com/wvector/appupdate/blob/master/kotlin.md

Shows how to configure a silent app update using the default protocol. This example restricts updates to Wi-Fi networks only, allowing the app to download updates in the background without user interaction.

```Kotlin
	  updateApp(mUpdateUrl, UpdateAppHttpUtil())
	        {
	            setOnlyWifi()
	        }.silenceUpdate()
```
