如何使用Android的应用内更新API？

Question

最近，我遇到了Google Play提供的一种新的应用更新流程。我喜欢无缝流程来更新Android应用程序。我在Hotstar应用程序中观察了以下提到的步骤。

1. 从底部弹出显示更新的卡
2. 当我单击“更新Hotstar”按钮时，弹出一个对话框（似乎是Google Play提供的）

3. 该应用程序正在运行时，下载已在后台开始
4. 下载完成后，一个SnackBar弹出，显示可以安装的应用程序
5. 安装后应用重新启动

我该如何实现？必须有一种与Google Play交流的方式。我浏览了许多博客。但是，没有找到任何解决方案。如果用户禁用了自动应用程序更新，这对于开发人员来说可能是一个很棒的功能。

官方文档： https : //developer.android.com/guide/app-bundle/in-app-updates

约束：应用内更新仅适用于运行Android 5.0（API级别21）或更高版本的设备

步骤1：添加依赖项：

dependencies {

    implementation 'com.google.android.play:core:1.6.3'
    ...
}

步骤2：检查更新的可用性，然后开始检查是否可用

mAppUpdateManager = AppUpdateManagerFactory.create(this);

mAppUpdateManager.registerListener(installStateUpdatedListener);

mAppUpdateManager.getAppUpdateInfo().addOnSuccessListener(appUpdateInfo -> {

        if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
                && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.FLEXIBLE)){

            try {    
                    mAppUpdateManager.startUpdateFlowForResult(
                            appUpdateInfo, AppUpdateType.FLEXIBLE, MainActivity.this, RC_APP_UPDATE);
                }

            } catch (IntentSender.SendIntentException e) {
                e.printStackTrace();
            }

        } else if (appUpdateInfo.installStatus() == InstallStatus.DOWNLOADED){
            popupSnackbarForCompleteUpdate();
        } else {
            Log.e(TAG, "checkForAppUpdateAvailability: something else");
        }
    });

步骤3：聆听更新状态

InstallStateUpdatedListener installStateUpdatedListener = new 
  InstallStateUpdatedListener() {
    @Override
    public void onStateUpdate(InstallState state) {
        if (state.installStatus() == InstallStatus.DOWNLOADED){
            popupSnackbarForCompleteUpdate();
        } else if (state.installStatus() == InstallStatus.INSTALLED){
            if (mAppUpdateManager != null){
          mAppUpdateManager.unregisterListener(installStateUpdatedListener);
            }

        } else {
            Log.i(TAG, "InstallStateUpdatedListener: state: " + state.installStatus());
        }
    }
};

步骤4：获取更新状态的回调

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RC_APP_UPDATE) {
        if (resultCode != RESULT_OK) {
            Log.e(TAG, "onActivityResult: app download failed");
        }
    }
}

步骤5：灵活更新

private void popupSnackbarForCompleteUpdate() {

    Snackbar snackbar =
            Snackbar.make(
                    findViewById(R.id.coordinatorLayout_main),
                    "New app is ready!",
                    Snackbar.LENGTH_INDEFINITE);

    snackbar.setAction("Install", view -> {
        if (mAppUpdateManager != null){
            mAppUpdateManager.completeUpdate();
        }
    });


snackbar.setActionTextColor(getResources().getColor(R.color.install_color));
    snackbar.show();
}

Answer 2

请尝试一次。官方文档供参考

步骤1：在build.gradle文件中添加以下库（请检查并更新最新的播放代码插件版本）

implementation 'com.google.android.play:core:1.6.4'

第二步：在类中声明如下变量（Ex MainActivity.java）

    private AppUpdateManager mAppUpdateManager;
    private int RC_APP_UPDATE = 999;
    private int inAppUpdateType;
    private com.google.android.play.core.tasks.Task<AppUpdateInfo> appUpdateInfoTask;
    private InstallStateUpdatedListener installStateUpdatedListener;

第 3 步：在 onCreate() 方法中添加以下代码（初始化变量）

        // Creates instance of the manager.
        mAppUpdateManager = AppUpdateManagerFactory.create(this);
        // Returns an intent object that you use to check for an update.
        appUpdateInfoTask = mAppUpdateManager.getAppUpdateInfo();
        //lambda operation used for below listener
        //For flexible update
        installStateUpdatedListener = installState -> {
            if (installState.installStatus() == InstallStatus.DOWNLOADED) {
                popupSnackbarForCompleteUpdate();
            }
        };
        mAppUpdateManager.registerListener(installStateUpdatedListener);

第 4 步：在 onDestroy() 活动方法中，只需取消注册侦听器

 @Override
    protected void onDestroy() {
        mAppUpdateManager.unregisterListener(installStateUpdatedListener);
        super.onDestroy();
    }

第 5 步：在 onResume() 中，我们需要通过以下代码收听灵活和立即更新。

@Override
        protected void onResume() {
           try {   
  mAppUpdateManager.getAppUpdateInfo().addOnSuccessListener(appUpdateInfo -> {
        if (appUpdateInfo.updateAvailability() == 
           UpdateAvailability.DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS) {
           // If an in-app update is already running, resume the update.
                       try {
                            mAppUpdateManager.startUpdateFlowForResult(
                                    appUpdateInfo,
                                    inAppUpdateType,
                                    this,
                                    RC_APP_UPDATE);
                        } catch (IntentSender.SendIntentException e) {
                            e.printStackTrace();
                        }
                    }
                });
    
       
  mAppUpdateManager.getAppUpdateInfo().addOnSuccessListener(appUpdateInfo -> {
     //For flexible update            
       if (appUpdateInfo.installStatus() == InstallStatus.DOWNLOADED) {
                        popupSnackbarForCompleteUpdate();
                    }
                });
            } catch (Exception e) {
                e.printStackTrace();
            }
    
            super.onResume();
    }

第六步：在onActivityResult()中我们需要处理用户的点击动作（仅用于灵活更新）

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_APP_UPDATE) {
            //when user clicks update button
            if (resultCode == RESULT_OK) {
                Toast.makeText(MainActivity.this, "App download starts...", Toast.LENGTH_LONG).show();
            } else if (resultCode != RESULT_CANCELED) {
                //if you want to request the update again just call checkUpdate()
                Toast.makeText(MainActivity.this, "App download canceled.", Toast.LENGTH_LONG).show();
            } else if (resultCode == RESULT_IN_APP_UPDATE_FAILED) {
                Toast.makeText(MainActivity.this, "App download failed.", Toast.LENGTH_LONG).show();
            }
        }
}

第 7 步：创建一个方法来检查更新是否可用并开始更新（立即更新）

private void inAppUpdate() {

        try {
            // Checks that the platform will allow the specified type of update.
            appUpdateInfoTask.addOnSuccessListener(new OnSuccessListener<AppUpdateInfo>() {
                @Override
                public void onSuccess(AppUpdateInfo appUpdateInfo) {
                    if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
                            // For a flexible update, use AppUpdateType.FLEXIBLE
                            && appUpdateInfo.isUpdateTypeAllowed(inAppUpdateType)) {
                        // Request the update.

                        try {
                            mAppUpdateManager.startUpdateFlowForResult(
                                    // Pass the intent that is returned by 'getAppUpdateInfo()'.
                                    appUpdateInfo,
                                    // Or 'AppUpdateType.FLEXIBLE' for flexible updates.
                                    inAppUpdateType,
                                    // The current activity making the update request.
                                    MainActivity.this,
                                    // Include a request code to later monitor this update request.
                                    RC_APP_UPDATE);
                        } catch (IntentSender.SendIntentException ignored) {

                        }
                    }
                }
            });
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

第 8 步：精细地创建小吃对话框或任何警报，以向用户显示灵活更新已下载并准备好更新（需要使用操作开始更新 - 仅适用于灵活更新）

private void popupSnackbarForCompleteUpdate() {
        try {
        Snackbar snackbar =
            Snackbar.make(
                    findViewById(R.id.id_of_root_loyout),
                    "An update has just been downloaded.\nRestart to update",
                    Snackbar.LENGTH_INDEFINITE);

    snackbar.setAction("INSTALL", view -> {
        if (mAppUpdateManager != null){
            mAppUpdateManager.completeUpdate();
        }
    });
snackbar.setActionTextColor(getResources().getColor(R.color.install_color));
    snackbar.show();

        } catch (Resources.NotFoundException e) {
            e.printStackTrace();
        }
    } 

第 9 步：现在在您想要开始检查更新的任何位置调用具有应用内更新类型（灵活或立即）的方法。

//For Immediate 
inAppUpdateType = AppUpdateType.IMMEDIATE; //1
inAppUpdate();

//For Flexible 
inAppUpdateType = AppUpdateType.FLEXIBLE; //0
inAppUpdate();

要记住的要点：

1. 灵活更新将首先下载，然后它会通知用户下载完成，然后用户必须开始更新（上述步骤 8 给出的选项）。

2. 谷歌播放控制台有一个选项可以测试应用内共享，我们可以上传普通的apk（不需要签名的apk）进行测试。 https://support.google.com/googleplay/android-developer/answer/9303479?hl=en

3. 需要在您的测试设备 Play 商店应用中启用应用内共享选项。 如何为 Android 启用内部应用程序共享？

4. 尽管如此，Play商店中的任何问题，只需清除缓存并清除数据，然后重新启动设备一次并尝试。

Answer 4

Trying to implement this, the official Google Documentation quoted in the accepted answer is syntactically incorrect. It took some research, but I finally found the correct syntax:

Instead of:

// Creates an instance of the manager.
AppUpdateManager appUpdateManager = AppUpdateManagerFactory.create(context);

// Returns an intent object that you use to check for an update.
Task<AppUpdateInfo> appUpdateInfo = appUpdateManager.getAppUpdateInfo();

// Checks that the platform will allow the specified type of update.
if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
  // For a flexible update, use AppUpdateType.FLEXIBLE
  && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE)) {
              // Request the update.

    appUpdateManager.startUpdateFlowForResult(
        // Pass the intent that is returned by 'getAppUpdateInfo()'.
        appUpdateInfo,
        // Or 'AppUpdateType.FLEXIBLE' for flexible updates.
        AppUpdateType.IMMEDIATE,
        // The current activity making the update request.
        this,
        // Include a request code to later monitor this update request.
        MY_REQUEST_CODE);
}

Do this:

    private AppUpdateManager appUpdateManager;
    ...
    // onCreate(){ 
    // Creates instance of the manager.
    appUpdateManager = AppUpdateManagerFactory.create(mainContext);

    // Don't need to do this here anymore
    // Returns an intent object that you use to check for an update.
    //Task<AppUpdateInfo> appUpdateInfo = appUpdateManager.getAppUpdateInfo();

    appUpdateManager
            .getAppUpdateInfo()
            .addOnSuccessListener(
                    appUpdateInfo -> {

                        // Checks that the platform will allow the specified type of update.
                        if ((appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE)
                                && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE))
                        {
                            // Request the update.
                            try {
                                appUpdateManager.startUpdateFlowForResult(
                                        appUpdateInfo,
                                        AppUpdateType.IMMEDIATE,
                                        this,
                                        REQUEST_APP_UPDATE);
                            } catch (IntentSender.SendIntentException e) {
                                e.printStackTrace();
                            }
                        }
                    });

Then, code a similar bit of code in the onResume() override in case an install got hung up along the way:

//Checks that the update is not stalled during 'onResume()'.
//However, you should execute this check at all entry points into the app.
@Override
protected void onResume() {
    super.onResume();

    appUpdateManager
            .getAppUpdateInfo()
