I have a specific problem only with HTC EVO 3D, for a custom Android
app, which uses the default back side camera.
I use android.hardware.Camera and try to set its ColorEffect to
different values, using Camera.Parameters, and the default camera (on
the back side).
I’m checking the list of supported effects, using
getSupportedColorEffects() – I can see the list with supported strings
(“none”, “mono”, “aqua”, etc)
Then I use setColorEffect(effect), which is accepted.
I can also set the parameters to the created camera without problems.
However, if I set the ColorEffect to any of the supported strings
except “none” ( like “mono”, “aqua” , etc), it throws a
java.lang.RuntimeException: setParameters failed when I try to execute
camera.startPreview() .
If I set the ColorEffect to “none” or leave it as default (which is
“none” again), everything is fine.
This is happening only on EVO 3D. I can change any other
Camera.Parameters without problems (like focus, zoom, white balance,
etc).The only one which seems to be broken is setColorEffect()
Should I do something specifically for EVO 3D to set the ColorEffect,
or this is a bug and there will be a fix?
Here is a short snippet with “mono” : (the verification for supported
effects is not posted) :
public void surfaceCreated(SurfaceHolder arg0) {
try {
camera = Camera.open();
camera.setPreviewDisplay(holder);
Parameters params = camera.getParameters();
String effect = Parameters.EFFECT_MONO
params.setColorEffect(effect);
camera.setParameters(params);
camera.startPreview();
}
catch (Exception e){
// ..
}
}
