Data dev/graphics/fb0 or dev/fb0 file is stored in the data look like? Is not binary

            
You master them, the procedure is the ape to write a program to read image data from two documents such as the title, but returned later with c reads the data to the data layer is found to be normal java convert bitmap, seems to be to get The data in question. Ask the experts, read out the data from these two files are not binary data, or the other types of data. . Seeking advice. dev/graphics/fb0 dev/fb0 inside or removed in the end what is the data. .

The data is raw data, which is stored in the data format and the format you want to convert is not the same, I turn into ARGB_8888 format, paste the code
I deal

 
Get Screen Size: 
DisplayMetrics metrics = new DisplayMetrics (); 
WindowManager WM = (WindowManager) this.getSystemService (Context.WINDOW_SERVICE); 
Display display = WM.getDefaultDisplay (); 
display.getMetrics (metrics); 
int height = metrics.heightPixels; / / screen high 
Wide 
 / / screen; int width = metrics.widthPixels
/ / Get the display mode 
int pixelformat = display.getPixelFormat (); 
PixelFormat localPixelFormat1 = new PixelFormat (); 
PixelFormat.getPixelFormatInfo (pixelformat, localPixelFormat1); 
int deepth = localPixelFormat1.bytesPerPixel ;/ / bit depth 

InputStream stream = getInputStream (); 
byte [] piex = new byte [height * width * deepth]; 
DataInputStream dStream = new DataInputStream (stream); 
int i = 0; 
while (dStream.read (piex, 0, height * width * deepth)! = -1) {
/ / Save the image 
int [] colors = new int [height * width]; 
for (int m = 0; m if (m% 4 == 0) {
int r = (piex [m] & 0xFF); 
int g = (piex [m +1] & 0xFF); 
int b = (piex [m +2] & 0xFF); 
int a = (piex [m +3] & 0xFF); 
colors [m / 4] = (a << 24) + (r << 16) + (g << 8) + b; 
} 
} 
/ / Piex generate bitmap 
Bitmap bitmap = Bitmap.createBitmap (colors, width, height, Bitmap.Config.ARGB_8888); 

/ / Bitmap saved as png format: 
FileOutputStream out = new FileOutputStream ("/ mnt / sdcard / test" + x + "png."); 
bitmap.compress (Bitmap.CompressFormat.PNG, 100, out);

If blank, then a change of position of each try their value or the like can be used pure red color which position to test the value of the deposit is r
