Java 这是检测是否启用了辅助功能服务的好方法吗？

要检测我的辅助功能服务是否已启用，我首先将其放在清单中的单独进程中：

<service
    android:name=".MyAccessibilityService"
    android:label="@string/app_name"
    android:logo="@mipmap/ic_launcher_round"
    android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"
    android:process=":accessibilityProcess>
    <intent-filter>
        <action android:name="android.accessibilityservice.AccessibilityService" />
    </intent-filter>

    <meta-data
        android:name="android.accessibilityservice"
        android:resource="@xml/accessibilityservice" />
</service>

private boolean isAccessibilityProcessRunning() {
    ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    List<ActivityManager.RunningAppProcessInfo> procInfos = activityManager.getRunningAppProcesses();

    for (ActivityManager.RunningAppProcessInfo runningProInfo : procInfos) {
        if (runningProInfo.processName.contains("accessibilityProcess"))
            return true;
    }

    return false;
}
