App crushes after starting flash at the second time

App crushes after starting flash at the second time

Im trying to make the flashlight work but on the second I power it, the
app crushes because I've released the Camera.
This is my code:
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if
(getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_FLASH)){
if (!power){
processOnClick();
light.setImageResource(R.drawable.on);
button.setImageResource(R.drawable.clicked);
power=true;
//ToastLoadShout(getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_FLASH)+"");
}
else{
processOffClick();
light.setImageResource(R.drawable.off);
button.setImageResource(R.drawable.unclicked);
power=false;
}
}
else
{
msg.setVisibility(View.VISIBLE);
}
}
});
ok = (Button) findViewById(R.id.button1);
ok.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
msg.setVisibility(View.INVISIBLE);
}
});
}
private void processOnClick() {
if (manuName.contains("motorola")) {
DroidLED led;
try {
led = new DroidLED();
led.enable(true);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} else {
if (mCamera == null) {
try {
mCamera = Camera.open();
} catch (Exception e) {
e.printStackTrace();
}
}
if (mCamera != null) {
final Parameters params = mCamera.getParameters();
List<String> flashModes =
params.getSupportedFlashModes();
if (flashModes == null) {
return;
} else {
if (count == 0) {
params.setFlashMode(Parameters.FLASH_MODE_OFF);
mCamera.setParameters(params);
mCamera.startPreview();
}
String flashMode = params.getFlashMode();
if (!Parameters.FLASH_MODE_TORCH.equals(flashMode)) {
if
(flashModes.contains(Parameters.FLASH_MODE_TORCH))
{
params.setFlashMode(Parameters.FLASH_MODE_TORCH);
mCamera.setParameters(params);
} else {
// Toast.makeText(this,
// "Flash mode (torch) not
supported",Toast.LENGTH_LONG).show();
params.setFlashMode(Parameters.FLASH_MODE_ON);
mCamera.setParameters(params);
try {
mCamera.autoFocus(new
AutoFocusCallback() {
public void onAutoFocus(boolean
success, Camera camera) {
count = 1;
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
}
}
if (mCamera == null) {
return;
}
}
private void processOffClick() {
if (manuName.contains("motorola")) {
DroidLED led;
try {
led = new DroidLED();
led.enable(false);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} else {
if (mCamera != null) {
mCamera.stopPreview();
mCamera.release();
}
}
}

My question is how can I do that without getting the app crushed. Or
without releasing the camera
