+#### Configure proguard-rules.pro
+If you're using __`minifyEnabled true`__ with your Android release build, the plugin's __`HeadlessTask`__ class will be mistakenly *removed* and you will have [this crash](https://github.com/transistorsoft/react-native-background-fetch/issues/261).
+
+1.  Edit `android/app/proguard-rules.pro`.
+2.  Add the following rule:
+
+```bash
+# [react-native-background-fetch]
+-keep class com.transistorsoft.rnbackgroundfetch.HeadlessTask { *; }
+```
