RuntimeException on Camera.setParameters() on nexus one

Question

I copied the code from the answer here and I still am getting a RuntimeException: setParameters failed error on my nexus one. My manifest file has camera and wake_lock permi

Answer 1

Some open source camera project like opencamera always use try-catch to call Camera.setParameters:

private void setCameraParameters(Camera.Parameters parameters) {
    if( MyDebug.LOG )
        Log.d(TAG, "setCameraParameters");
    try {
        camera.setParameters(parameters);
        if( MyDebug.LOG )
            Log.d(TAG, "done");
    } catch (RuntimeException e) {
        // just in case something has gone wrong
        if( MyDebug.LOG )
            Log.d(TAG, "failed to set parameters");
        e.printStackTrace();
        count_camera_parameters_exception++;
    }
}

in addition，always get the latest getParameters before you call setParameters like this:

void setRotation(int rotation) {
    Camera.Parameters parameters = this.getParameters();
    parameters.setRotation(rotation);
    setCameraParameters(parameters);
}
