FC Error: java.lang.IllegalArgumentException: x + width must be <= bitmap.width ()

When you call Force Quit Application Screenshot:

 
public Bitmap takeScreenShot (Activity activity) {
/ / View is that you need screenshot View 
View view = activity.getWindow () getDecorView ();. 
view.setDrawingCacheEnabled (true); 
view.buildDrawingCache (); 
b1 = view.getDrawingCache (); 

/ / Get the status bar height 
Rect frame = new Rect (); 
activity.getWindow () getDecorView () getWindowVisibleDisplayFrame (frame);.. 
int statusBarHeight = frame.top; 
/ / Get the screen length and height 
.. int width = activity.getWindowManager () getDefaultDisplay () getWidth (); 
/ / Remove the title bar 
b = Bitmap.createBitmap (b1, 0, statusBarHeight, width, b1.getHeight ()-statusBarHeight); 
view.destroyDrawingCache (); 
return b; 
}

x + width must be <= bitmap.width () exceeds the width of the chart you want to cut the width of ~ width changed b1.getWidth () try ~

bitmap1.getPixel (i, j)

Submitted late, the last did not finish,
From the position (0,0) to take, a width and height should be less
bitmap1.getPixel (bitmap2.getWidth () -1, bitmap1.getHeight () -1);
