Everytime it hits the "c = mHolder.lockCanvas();" line, it pops up
with that same error mentioned below.
Also, I realize that c returns a null after called lockCanvas(), but
mHolder is still active. Why might this be?
I'm getting the following error as seen from the logcat window:
E/SurfaceComposerClient( 608): eLocked set when entering lock_layer
(), layer=1 (lcblk=0x410480a0), state=00000022
E/SurfaceHolder( 608): Exception locking surface
E/SurfaceHolder( 608): java.lang.IllegalArgumentException
E/SurfaceHolder( 608): at
android.view.Surface.lockCanvasNative(Native Method)
E/SurfaceHolder( 608): at android.view.Surface.lockCanvas
(Surface.java:190)
E/SurfaceHolder( 608): at android.view.SurfaceView
$2.internalLockCanvas(SurfaceView.java:549)
E/SurfaceHolder( 608): at android.view.SurfaceView
$2.lockCanvas(SurfaceView.java:528)
This is the basis of my code, which is primarily based on the
lunarview:
@Override
public void run() {
while (mRun) {
Canvas c = null;
try {
mHolder = getHolder(); //make sure holder is updated
c = mHolder.lockCanvas();
synchronized (mHolder) {
if (mMode == STATE_RUNNING && c != null){
doDraw(c);
}
}
} finally {
// do this in a finally so that if an exception is thrown
// during the above, we don't leave the Surface in an
// inconsistent state
if (c != null) {
mHolder.unlockCanvasAndPost(c);
}
}
}
}
Can someone get back to me ASAP, this is urgent.
Thanks a lot,
mcmc
