Android configuration file Androidmanifest parsing

1. Screen resolution

<supports-screens      android:smallscreens= "true"      android:normalscreens= "true"      Android:largescreens = "true"      android:resizeable= "true"      android:anydensity= "true"/>  

Displaymetrics metric = new Displaymetrics ();  Getwindowmanager (). Getdefaultdisplay (). Getmetrics (metric);  int width = metric.widthpixels;     Screen width (pixels)  int height = metric.heightpixels;   Screen height (pixels)  float density = metric.density;      Screen density (0.75/1.0/1.5)  int densitydpi = metric.densitydpi;  Screen density dpi (120/160/240)  

on a low-density small-screen phone, only the above code is not able to get the correct size. For example, a 240x320 pixel low-density mobile phone, if you run the above code, the screen size obtained is 320x427. As a result, the study found that without multi-resolution support, the Android system would convert the 240x320 low-density (120) size to a medium-density (160) dimension, which would greatly affect the coding of the program. Therefore, you need to join the Supports-screens node in the project's Androidmanifest.xml file.
