You can enable debugging in Firebase using following code. Firebase.getDefaultConfig().setLogLevel(Logger.Level.DEBUG);   Output will be look like following snapshot. 05-14 02:32:11.089 6645-7531/com.aybits.discoversaints.discoversaints D/PersistentConnection: pc_0 - Listening on /saints/video:{} 05-14 02:32:11.089 6645-7531/com.aybits.discoversaints.discoversaints D/PersistentConnection: pc_0 - Adding listen query: /saints/video:{} 05-14 02:32:18.001 6645-7531/com.aybits.discoversaints.discoversaints D/PersistentConnection: pc_0 - unlistening on /saints/video:{} 05-14 02:32:18.001 6645-7531/com.aybits.discoversaints.discoversaints D/PersistentConnection: pc_0 - removing query /saints/video:{} 05-14 02:32:18.002 6645-7531/com.aybits.discoversaints.discoversaints D/PersistentConnection: pc_0 - Listening on /saints/video:{} 05-14 02:32:18.002 6645-7531/com.aybits.discoversaints.discoversaints D/PersistentConnection: pc_0 - Adding listen query: /saints/video:{}

Sometimes we need to convert density independent pixels(dip/dp) to pixels to set view properties like width or height. Here how it is done using Java.     Resources r = getResources();     int px = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 300,       r.getDisplayMetrics());     myEditText.setWidth(px);
