aDosBox crashes during multitouch #134

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. On a multitouch device, press two fingers down and with a third finger move 
across the screen
2. aDosBox crashes.

Various permutations of the above will also cause crash, and also with fewer 
than three fingers.

What version of the product are you using? On what operating system?
Using adosbox 0.2.5 on Android 4.0.4 on a Droid Bionic

Please provide any additional information below.

Following the stack trace led me to the last responsible line in aDosBox java 
code, which is line 152 in Video.java -- 
DifferentTouchInput$MultiTouchInput.process(). I believe the culprit is an 
incorrect use of MotionEvent.getX() -- instead of "i", which may be outside the 
valid input range for getX, use getPointerId(i), similar to what was used 
previously in the same function.

This is my initial assessment, so I may be inadequately debugging -- note that 
the final exception is thrown from MotionEvent.nativeGetAxisValue and is an 
"IllegalArgumentException: pointerIndex out of range" which may substantiate my 
diagnosis.

I have exactly the same problem with multitouching using games like xargon or 
hocus pocus.
