v0.8.7-beta.4

More tweaks to MQTT buffer settings to prevent crashes on some devices. I also added a check that the browser view is active when setting an alert using JavaScript.

Install the APK by side-loading onto your device using the Android ADB command line tool or download the APK file directly to your device and open it. You can also download the latest version from the Google Play store https://play.google.com/store/apps/details?id=com.thanksmister.iot.wallpanel.
