Android implements screenshots and saves operation functions _android

This article describes how to implement the ability to intercept the current screen on an Android phone or tablet, and save the intercepted screen under a directory folder in SDcard. The
implemented code is as follows:

/** * Capture and save screenshot of current screen/private void Getandsavecurrentimage () {//1. Build bitmap WindowManager WindowManager = Getwin 
 Dowmanager (); 
 Display display = Windowmanager.getdefaultdisplay (); 
 int w = display.getwidth (); 
  
 int h = display.getheight ();  
  
 Bitmap Bmp = Bitmap.createbitmap (W, H, config.argb_8888);  
 2. Get screen View Decorview = This.getwindow (). Getdecorview ();  
 Decorview.setdrawingcacheenabled (TRUE);  
  
 BMP = Decorview.getdrawingcache (); 
 
 String Savepath = Getsdcardpath () + "/andydemo/screenimage"; 
  3. Save Bitmap try {file path = new file (Savepath); 
  File String filepath = savepath + "/screen_1.png"; 
  File File = new file (filepath); 
  if (!path.exists ()) {path.mkdirs (); 
  } if (!file.exists ()) {file.createnewfile (); 
  FileOutputStream fos = null; 
  FOS = new FileOutputStream (file); 
   if (null!= fos) {bmp.compress (Bitmap.CompressFormat.PNG, N, FOS); 
   Fos.flush ();  
    
   Fos.close (); Toast.maketext (MconteXT, "screenshot file has been saved to sdcard/andydemo/screenimage/", Toast.length_long). Show (); 
 } catch (Exception e) {e.printstacktrace (); 
 /** * Gets sdcard directory path feature * @return/private String Getsdcardpath () {File sdcarddir = null; Determine if sdcard exists boolean sdcardexist = Environment.getexternalstoragestate (). Equals (android.os.Environment.MEDIA_ 
 mounted); 
 if (sdcardexist) {sdcarddir = Environment.getexternalstoragedirectory (); 
return sdcarddir.tostring ();  }

Because you want to operate on sdcard, don't forget to assign the read and write permissions to SDcard in the Manifest.xml file:
