Android error: Fail to connect to camera service on Camera.open()?
Phone: HTC Incred开发者_运维技巧ible 2 with Gingerbread 2.3.3
In my code, I am doing:
cam = Camera.open(0);
SurfaceHolder surfaceHolder = getSurfaceHolder();
try
{
cam.setPreviewDisplay(surfaceHolder);
cam.startPreview();
}
catch (IOException e)
{
e.printStackTrace();
}
In the constructor of an Engine
I also have:
@Override
public void onDestroy()
{
super.onDestroy();
if (cam != null)
{
cam.stopPreview();
cam.setPreviewCallback(null);
cam.release();
cam = null;
}
}
and
@Override
public void onSurfaceDestroyed(SurfaceHolder holder)
{
super.onSurfaceDestroyed(holder);
if (cam != null)
{
cam.stopPreview();
cam.setPreviewCallback(null);
cam.release();
cam = null;
}
}
My manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.google.apis" android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.software.live_wallpaper" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<service android:label="@string/label"
android:name="com.me.app.main.AppName"
android:permission="android.permission.BIND_WALLPAPER">
<intent-filter>
<action android:name="android.service.wallpaper.WallpaperService" />
</intent-filter>
<meta-data android:name="android.service.wallpaper"
android:resource="@xml/app" />
</service>
<activity
android:name="com.me.app.main.AppName"
android:label="@string/app_name">
android:exported="true">
</activity>
</application>
</manifest>
I figured it out. Turns out the Camera.open() call has to be made in the Activity, not in the Engine.
Still not sure why this is the case. I would appreciate if someone can explain this phenomenon to me.
After stop the cameraPreview release camera object.
Try this
stopCameraPreview(){
if(camera != null){
camera.stopPreview();
camera.release();
}
}
