好吧,我再次更新了我的问题,完全是这一次。
我已经在 Galaxy Nexus(JB)、Moto-XX(GB)、SAMSUNG(Froyo) 上一一测试了以下代码,出现了不同的问题/异常。
public class MainActivity extends Activity {
@SuppressLint("NewApi")
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ShutterCallback shutterCallback = new ShutterCallback() {
public void onShutter() {
System.out.println("shutterCallback");
}
};
PictureCallback rawCallback = new PictureCallback() {
public void onPictureTaken(byte[] data, Camera camera) {
System.out.println("onPictureTaken");
}
};
PictureCallback jpegCallback = new PictureCallback() {
public void onPictureTaken(byte[] data, Camera camera) {
System.out.println("jpegCallback");
FileOutputStream outStream = null;
try {
System.out.println("jpegCallback begin");
camera.startPreview();
File storagePath = new File("/mnt/sdcard/");
File myImage = new File(storagePath, "example2.jpg");
outStream = new FileOutputStream(myImage);
outStream.write(data);
outStream.close();
} catch (FileNotFoundException e) {
System.out.println("jpegCallback FileNotFoundException");
e.printStackTrace();
} catch (IOException e) {
System.out.println("jpegCallback IOException");
e.printStackTrace();
} finally {
camera.stopPreview();
camera.release();
}
}
};
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
for (int i = 0; i < Camera.getNumberOfCameras(); i++) {
Camera.CameraInfo info = new Camera.CameraInfo();
Camera.getCameraInfo(i, info);
if (info.facing == Camera.CameraInfo.CAMERA_FACING_BACK) {
try{
Camera camera = Camera.open(i);
Camera.Parameters parameters = camera.getParameters();
camera.setParameters(parameters);
camera.startPreview();
camera.setPreviewDisplay(null);
System.out.println("takePicture ahead");
camera.takePicture(null, rawCallback, jpegCallback);
System.out.println("takePicture finish");
}
catch (Exception e){
System.out.println("printStackTrace");
e.printStackTrace();
}
}
}
}
}
具体问题如下:
在 Android4.1&4.2中,有三部分异常:
1.由“Camera camera = Camera.open(i);”引起
11-26 00:36:29.144: D/DOMX(132): ERROR: failed check:status >= 0 - returning error: 0x81000 - Can't connect

11-26 00:36:29.144: E/CameraHAL(132): OMX_GetHandle() failed, error: 0x80001001
2.由“camera.startPreview();”引起
11-26 00:36:30.488: D/DOMX(132): ERROR: failed check:(eError == OMX_ErrorNone) || (eError == OMX_ErrorNoMore) - returning error: 0x80001005 - Error returned from OMX API in ducati
11-26 00:36:30.488: E/CameraHAL(132): Error while configuring rotation 0x80001005
3.由“camera.takePicture()”引起
11-26 00:36:30.495: E/CameraHAL(132): Adapter state switch INTIALIZED_STATE Invalid Op! event = 0x13
11-26 00:36:30.738: D/DOMX(132): ERROR: failed check:(eError == OMX_ErrorNone) || (eError == OMX_ErrorNoMore) - returning error: 0x80001005 - Error returned from OMX API in ducati
11-26 00:36:30.738: E/CameraHAL(132): Exiting function UseBuffersCapture because of ret 0 eError=80001005
因此,结果是,即使在 Galaxy Nexus i9250 等普通设备中,照片也不是在 Jelly Bean 中拍摄的。
接下来在 Android2.3中,有两部分异常:
1.caused by "Camera camera = Camera.open(i);"
E/CameraSettings(1235): Param type 53 not supported
E/CameraSettings(1235): Param type 51 not supported
E/CameraSettings(1235): Param type 50 not supported
2.尽管如此,camera.takePicture() 仍然可以执行。结果显示照片被拍了。除了一个问题:“E/MemoryHeapBase(1235): mmap(fd=50, size=0) failed (Invalid argument)”

11-26 01:28:33.882: I/AwesomePlayer(1235): reset_l
因此,在Android2.3中,拍照后都不会调用shutterCallback、rawCallback和jpegCallback中的任何一个。
之后,在 Android2.2中,拍照后会调用 shutterCallback 和 rawCallback。但他们都不能为我提供数据(字节流)。如http://developer.android.com/reference/android/hardware/Camera.html#takePicture(android.hardware.Camera.ShutterCallback, android.hardware.Camera.PictureCallback, android.hardware.Camera.PictureCallback)中介绍的 ,如果没有可用的原始图像回调缓冲区或原始图像回调缓冲区不足以容纳原始图像,则数据将为空。而且我确实在 rawCallback 中得到了空数据。
这都是硬件不兼容还是代码故障造成的?
请帮忙
