java - Android PlayStore 'InAppUpdate' 绝对强制升级(必须立即升级，不能取消任何选项)

Question

我有下面的代码，我已经成功地实现了 InAPPUpdate 代码，根据下面的屏幕截图，它工作正常。但是，在此实现中，用户仍然可以使用 (X) 关闭按钮取消 InAppUpdate，并且在下载应用更新时用户仍然可以取消更新。

我的问题是有没有一种方法可以绝对强制最终用户更新应用程序？除非他们更新，否则我需要阻止他们使用该应用。

注意:(请不要问为什么要强制不是讨论的问题)

public class MainActivity extends BaseActivity implements TabLayout.OnTabSelectedListener, MainView {

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //check for updates
        validateAppUpdate();
}

//in app updates
    private void validateAppUpdate() {
        // Creates instance of the manager.
        appUpdateManager = AppUpdateManagerFactory.create(getBaseContext());

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

        // Checks that the platform will allow the specified type of update.
        appUpdateInfoTask.addOnSuccessListener(new OnSuccessListener<AppUpdateInfo>() {
            @Override
            public void onSuccess(AppUpdateInfo appUpdateInfo) {

                Log.e("AVAILABLE_VERSION_CODE", appUpdateInfo.availableVersionCode()+"");
                Log.e("AVAILABLE_VERSION_CODE_2", appUpdateInfo.updateAvailability()+"");
                //Log.e("html", "Error loading html/index.html", e);
                 if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
                        // For a flexible update, use AppUpdateType.FLEXIBLE
                        && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE)) {
                    // Request the update.

                    try {
                        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.
                                MainActivity.this,
                                // Include a request code to later monitor this update request.
                                UPDATE_REQUEST_CODE);
                    } catch (IntentSender.SendIntentException ignored) {

                    }
                }else{
                    System.out.println("No Update Available.");
                }
            }
        });

        appUpdateManager.registerListener(installStateUpdatedListener);

    }
    //lambda operation used for below listener
    InstallStateUpdatedListener installStateUpdatedListener = installState -> {
        if (installState.installStatus() == InstallStatus.DOWNLOADED) {
            popupSnackbarForCompleteUpdate();
        }
    };


    private void popupSnackbarForCompleteUpdate() {

        Snackbar snackbar =
                Snackbar.make(
                        findViewById(android.R.id.content),
                        "Update almost finished!",
                        Snackbar.LENGTH_INDEFINITE);
        //lambda operation used for below action
        snackbar.setAction(this.getString(R.string.APP_NAME), view ->
                appUpdateManager.completeUpdate());
        snackbar.setActionTextColor(getResources().getColor(R.color.browner));
        snackbar.show();
    }

Answer 1

你需要在你的类中覆盖 onActivityResult() 来扩展 Activity ，如下所示:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode != RESULT_OK) {
        validateAppUpdate();
    }
}

这将运行 validateAppUpdate() 直到应用更新。
