/**
 * A {@link BroadcastReceiver} that injects its members in every call to {@link #onReceive(Context,
 * Intent)}.
 *
 * <p>This class should only be used for {@link BroadcastReceiver}s that are declared in an {@code
 * AndroidManifest.xml}. If, instead, the {@link BroadcastReceiver} is created in code, prefer
 * constructor injection.
 *
 * <p>Note: this class is <em>not thread safe</em> and should not be used with multiple {@link
 * android.os.Handler}s in calls to {@link Context#registerReceiver(BroadcastReceiver,
 * android.content.IntentFilter, String, android.os.Handler)}. Injection is performed on each
 * invocation to {@link #onReceive(Context, Intent)} which could result in inconsistent views of
 * injected dependencies across threads.
 *
 * <p>Subclasses should override {@link #onReceive(Context, Intent)} and call {@code
 * super.onReceive(context, intent)} immediately to ensure injection is performed immediately.
