拍照失败java.lang.runtimeexception无法启动服务

我有个例外 “无法使用intent java.lang启动服务。runtimeexception拍摄照片失败”。
我用我必须使用的服务扩展了我的课程。我不想延长活动时间

这是我的简单代码：

public class LaunchActivity extends Service  {


        Camera camera;
    @Override
        public int onStartCommand(Intent intent, int flags, int startId) {
            // TODO Auto-generated method stub
            try {
                TakePhoto();
            } catch (IOException e2) {
                // TODO Auto-generated catch block
                e2.printStackTrace();
            }
    }
    public void TakePhoto() throws IOException{
            //findFrontFacingCamera();
            int cameraId = -1;  
            int numberOfCameras = Camera.getNumberOfCameras();  
             for (int i = 0; i < numberOfCameras; i++) {  
                  CameraInfo info = new CameraInfo();  
                  Camera.getCameraInfo(i, info);  
                  if (info.facing == CameraInfo.CAMERA_FACING_FRONT) {  
                       Log.v("MyActivity", "Camera found");  
                       cameraId = i;  
                 break;  
                }  
               }  

              // safeCameraOpen(cameraId); 

               boolean qOpened = false;  
                try {  
                     if (camera != null) {  
                         camera.stopPreview();  
                      camera.release();  
                      camera = null;  
                    }    
                  camera = Camera.open(cameraId);  
                  qOpened = (camera != null);  
                } catch (Exception e) {  
                  Log.e(getString(R.string.app_name), "failed to open Camera");  
                  e.printStackTrace();  
                }  


              SurfaceView view = new SurfaceView(getApplicationContext());  
                try {  
                        camera.setPreviewDisplay(view.getHolder());  
                   } catch (IOException e) {  
                        // TODO Auto-generated catch block  
                        e.printStackTrace();  
                   }  
                camera.startPreview();  
                Camera.Parameters params = camera.getParameters();  
                params.setJpegQuality(100);  
                camera.setParameters(params); 

                camera.takePicture(null, null, jpegCallback);    
           }

 // This method are taking photos.

        PictureCallback jpegCallback = new PictureCallback() {
            public void onPictureTaken(byte[] data, Camera camera) 
            {
                FileOutputStream outStream = null;
                try {
                  String fileName = "Image.jpg";
                    String backPicPath = Environment.getExternalStorageDirectory().getPath()+ "/FolderName/"+fileName;

              //String dir_path = "";// set your directory path here
                    outStream = new FileOutputStream(backPicPath);    
                    outStream.write(data);
                    outStream.close();
                    Log.d("asdas", "onPictureTaken - wrote bytes: " + data.length);
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } finally 
                {
                    camera.stopPreview();
                    camera.release();
                    camera = null;
                    Toast.makeText(getApplicationContext(), "Image snapshot Done",Toast.LENGTH_LONG).show();


                }
                Log.d("asd", "onPictureTaken - jpeg");
            }
            };
    }

我在运行我发现的类似代码时遇到了相同的错误。为了解决这个问题，我在

mCamera.startPreview（）；

之前添加了

SurfaceTexture st=new SurfaceTexture（MODE_PRIVATE）；

mCamera.setPreviewTexture（st）；

，感谢Viren Kheni的帮助

因此，根据您的代码，我建议您添加

SurfaceTexture st = new SurfaceTexture(MODE_PRIVATE);
camera.setPreviewTexture(st);

---

在

TakePhoto（）

方法中的

camera.startPreview（）；

之前。

实际上错误发生在camera.takePicture（null、null、jpeg）上；line你为什么不在

活动中做这件事

？你是想监视你的妻子吗？因为我在这个类中使用了几种方法，这些方法是从service扩展而来的。我不认为它们在你的代码中有任何用处，在你的活动中做同样的事情。我使用过它们，我没有添加我的服务代码

SurfaceTexture st = new SurfaceTexture(MODE_PRIVATE);
camera.setPreviewTexture(st);
