Hi everyone,
i create my own class which extends camera class
(android.hardware.camera).
i want to check if application can use my own class instead of
android.hardware.camera when i run ApiDemos.
i write one function to be override and a new function in my own
class. Those codes i modify are:
A.the MyCamera.java in android\frameworks\base\core\java\android
\hardware :
>>>>>>>>
package android.hardware;
import android.hardware.Camera;
public class MyCamera extends Camera{
int test1;
int test2;
public MyCamera(){
test1 = 0;
}
// Override the function in android.hardware.Camera //
public int getJpegQuality() {
test1 = 8;
return test1;
}
public int mytest() {
test2 = 9;
return test2;
}
}
>>>>>>>>
B. The CameraPreview.java in android_sdk\samples\android-8\ApiDemos\src
\com\example\android\apis\graphics:
>>>>>>>>
package com.example.android.apis.graphics;
import android.app.Activity;
import android.content.Context;
import android.hardware.Camera;
import android.hardware.Camera.Size;
import android.os.Bundle;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.Window;
import android.hardware.MyCamera;
import java.io.IOException;
import java.util.List;
public class CameraPreview extends Activity {
private Preview mPreview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Hide the window title.
requestWindowFeature(Window.FEATURE_NO_TITLE);
MyCamera mycamera = new MyCamera();
int tmp1 = 0;
int tmp2 = 0 ;
tmp1 = mycamera.mytest();
tmp2 = mycamera.getJpegQuality();
// Create our Preview view and set it as the content of our
activity.
mPreview = new Preview(this);
setContentView(mPreview);
}
.....
.....
>>>>>>>>
i also add MyCamera class infomation in android.jar(extract
MyCamera.java
from android\out\target\common\obj\JAVA_LIBRARIES
\android_stubs_current_intermediates\javalib.jar
and add it in android_sdk\platforms\android-8\android.jar)
and when i use eclipse to debug my code, i get
"ERROR/dalvikvm(266): Could not find class
'android.hardware.MyCamera',
referenced from method
com.example.android.apis.graphics.CameraPreview.onCreate"
Please give me any suggestion.
Thanks a lot.
Steven
