# Kiwix Android Kiwix is an offline reader for Web content. One of its main purposes is to make Wikipedia available offline. This is done by reading the content of a file in the ZIM format, a highly compressed open format with additional metadata. This is the version for Android, with support versions ranging from 5 to 13 (like [mentioned here](https://github.com/kiwix/kiwix-android/blob/develop/buildSrc/src/main/kotlin/Config.kt)). **Important Note**: Starting from Android 11, the zim file picker feature has been restricted in the Play Store variant due to Play Store policies. This means that users running Android 11 and above will not be able to load zim files from internal/external storage directly within the app. This restriction is in place to comply with the Play Store policies. The Play Store variant of the Kiwix app does not have the `MANAGE_EXTERNAL_STORAGE` permission, which is required for scanning storage and accessing zim files from arbitrary locations. Therefore, the storage scanning functionality is not available in this variant. To use the full version of the Kiwix app and access the zim file picker feature, you can download it directly from the [official page](https://download.kiwix.org/release/kiwix-android/). The website allows you to download the full version of the app, which includes the unrestricted file picker feature. We understand that this restriction may cause inconvenience, but it is necessary to comply with the Play Store policies and ensure a smooth user experience. We recommend using the official version of the app available on our website to access the complete set of features.

Note here that instead of *opening* the project, you have to *import* it. If you prefer to build without Android Studio you must first set up the Android SDK and then run the command: `./gradlew build ` from the root directory of the project. Kiwix-Android is a multi-module project, in 99% of scenarios you will want to build the `app` module in the `debug` configuration.
