我有例外 “无法以意图启动服务java.lang.runtimeexception拍照失败”。 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");
}
};
}
这是我的logcat

当我运行类似的代码时遇到同样的错误here。为解决此问题，我在SurfaceTexture st = new SurfaceTexture(MODE_PRIVATE);之前添加了mCamera.setPreviewTexture(st); mCamera.startPreview();。感谢Viren Kheni this answer。
根据您的代码，我建议您添加
SurfaceTexture st = new SurfaceTexture(MODE_PRIVATE);
camera.setPreviewTexture(st);
camera.startPreview();方法{。}}之前。
