FreeDroidWarn is a Java library for Android that displays an alert dialog warning users about upcoming Google developer verification requirements for Android apps distributed outside the Play Store. Starting in 2026/2027, Google will require developers to submit personal identity details directly for all apps on certified Android devices. The developers of FreeDroidWarn do not agree to this requirement, so the app will no longer function on certified devices after this time. Installation instructions: - Add the JitPack repository to your root build.gradle file under allprojects -> repositories. - Add the dependency implementation 'com.github.woheller69:FreeDroidWarn:V1.3' to your build.gradle. Usage: - Call FreeDroidWarn.showWarningOnUpgrade(this, BuildConfig.VERSION_CODE); in the onCreate method of your app. The library is licensed under the GNU GPLv3 license.
