When users browse to the download link from their Android-powered devices, the file is downloaded and Android system automatically starts installing it on the device. However, the installation process will start automatically only if the user has configured their Settings to allow the installation of apps from unknown sources.
Although it is relatively easy to release your application on your own website, it can be inefficient. For example, if you want to monetize your application you will have to process and track all financial transactions yourself and you will not be able to use Google Play's In-app Billing service to sell in-app products. In addition, you will not be able to use the Licensing service to help prevent unauthorized installation and use of your application.
Android protects users from inadvertent download and install of apps from locations other than a first-party app store, such as Google Play, which is trusted. Android blocks such installs until the user opts into allowing the installation of apps from other sources. The opt-in process depends on the version of Android running on the user's device:.
Figure 1. The Install unknown apps system settings screen, where users grant permission for a particular source to install unknown apps. On devices running Android 8. To do so, they must enable the Allow app installs setting for that source within the Install unknown apps system settings screen.
Figure 1 illustrates this process. Note: Users can change this setting for a particular source at any time. Therefore, a source that installs unknown apps should always call canRequestPackageInstalls to check whether the user has granted that source permission to install unknown apps. If this method returns false , the source should prompt the user to re-enable the Allow app installs setting for that source.
Figure 2. The Unknown sources setting, which determines whether users can install apps that aren't downloaded from Google Play.
In order for users to allow the installation of apps from non-first-party sources on devices running Android 7.
Note: When users attempt to install an unknown app on a device running Android 7. In almost all cases, users should allow only one unknown app installation at a time if the option is available to them. In either case, users need to make this configuration change before they can download and install unknown apps onto their devices. Note: Some network providers do not allow users to install apps from unknown sources.
