Googleのルールでは、Playストアはサードパーティのアプリストアを配布しないと長い間考えられてきましたが、ユーザーが同意し、マルウェアが関与しない限り、アプリがAPKをインストールすることを禁止するポリシーはこれまでありませんでした。 However, this is changing as new rules are aimed at this feature and are limited to a fairly narrow group of apps.
This effectively means that you only need the ability to install the APK in your app if it’s clearly needed by your app type (for example, a file manager or web browser). Counterexamples are games, podcast players, camera apps, and so on. You don’t have to install other apps yourself.
At the heart of this policy change is an Android OS permission called REQUEST_INSTALL_PACKAGES that has been around since Android 6.0 Marshmallow. この権限がアプリのマニフェストに含まれている場合、つまりアプリがこの機能が必要であると宣言しているIf so, you can trigger an installation request that asks the user to allow the APK installation to continue. Apps that do not declare this permission will not be affected by the policy. However, it’s notable that app developers should check that any third-party libraries included in their apps have not added this permission either, including ad networks.
Why is this rule added? Googleは変更の説明を投稿していませんが、ユーザーをPlayストアに誘導せずにデバイスにAPKをインストールしようとする広告ネットワークなど、人気が高まっている悪意のある戦術を阻止することを目的としている可能性があります。
Google’s new policy lists a set of features and app types that are considered acceptable.
- Web browsing or search;
- Communication services that support attachments;
- File sharing, transfer or management;
Note that the requirements also specify that APK self-updating, modification, and bundling are prohibited. However, there are exceptions to device management. This usually fits into the area of enterprise software and deployment tools.
The new policy is set to take effect on August 11, 2022. However, it’s not clear how these rules apply, whether the Play Store simply blocks updates for apps that include permissions, or whether existing apps will be private until the developer publishes them. new versions of their apps. When history is needed, Google usually prefers to remove apps first and clean up the mess later. In short, app developers need to be as aggressive as possible to avoid complexity.
This policy change heats up following another Play Store announcement that older API-level apps will be hidden from search, and joins another announcement that establishes a stricter stance on children’s apps. increase.
