java.lang.RuntimeException: takePicture failed
Solution 1
Firstly, catch your exceptions in onPictureTaken, leaving empty catch sections is not a good practice. Then, I would add a flag that would prevent from calling takePicture() while previous picture is being saved. Later in your button onClick you would check if it's ok to call takePicture().
-
Declare a flag as a member of your Activity:
private boolean safeToTakePicture = false;
-
In
surfaceChanged()
, just set the flag to true after calling startPreview():camera.startPreview(); safeToTakePicture = true;
-
In your
onClick()
listener check the flag and take picture if ok to do so:if (safeToTakePicture) { mp.start(); camera.takePicture(null, null, mPicture); safeToTakePicture = false; }
-
In
onPictureTaken()
, set the flag again to true after picture has been saved (and add exception printing):PictureCallback mPicture = new PictureCallback() { @Override public void onPictureTaken(byte[] data, Camera camera) { pictureFile = getOutputMediaFile(); camera.startPreview(); if (pictureFile == null) { //no path to picture, return safeToTakePicture = true; return; } try { FileOutputStream fos = new FileOutputStream(pictureFile); fos.write(data); fos.close(); } catch (FileNotFoundException e) { e.printStackTrace(); //<-------- show exception } catch (IOException e) { e.printStackTrace(); //<-------- show exception } //finished saving picture safeToTakePicture = true; } };
NOTES: As the docs say, "Preview must be started before you can take a picture.", so possible enhancement would be to use setPreviewCallback() to register callback that will be called when preview data is available, and set the flag to true when onPreviewFrame is called.
Solution 2
I also had the similar issue. later i found startPreview
is very important.
_camera.startPreview()
is very important before the takePicutre checkout the point 5 and 6
in this link.
Solution 3
There can be many reasons for this in my case i was trying to take photo without preview (hidden photo) and i was using SurfaceView
, So i replaced it with SurfaceTexture
SurfaceTexture surfaceTexture = new SurfaceTexture(10);
camera.setPreviewTexture(surfaceTexture);
and the problem was solved... P.S I was getting this error only on Above 6.0 devices

when i do continuous click on Capture button (without any break), getting Runtime Exception how can i resolve this issue ?
if its not possible so how may i handle this Exception ?
btnCapture = (ImageButton) findViewById(R.id.btnCapture); final MediaPlayer mp = MediaPlayer.create(CameraLauncherActivity.this, R.raw.button); btnCapture.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // line where getting RuntimeException camera.takePicture(null, null, mPicture); } });

Note:- Like in Pudding Camera, they allow user to do continuous tap on Capture button, but they will never show exception, if you do 50 clicks it will capture 10 or more images, each image after specific time but not showing exception, like i am getting in my code, in a same way how can i handle this exception ?
Complete Code:
@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_camera); setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); preview=(SurfaceView)findViewById(R.id.surface); previewHolder=preview.getHolder(); previewHolder.addCallback(surfaceCallback); previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); btnCapture = (ImageButton) findViewById(R.id.btnCapture); final MediaPlayer mp = MediaPlayer.create(CameraLauncherActivity.this, R.raw.button); btnCapture.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { mp.start(); camera.takePicture(null, null, mPicture); } }); @Override public void onResume() { super.onResume(); camera=Camera.open(); } @Override public void onPause() { super.onPause(); if (inPreview) { camera.stopPreview(); } camera.release(); camera=null; inPreview=false; } private Camera.Size getBestPreviewSize(int width, int height, Camera.Parameters parameters) { Camera.Size result=null; for (Camera.Size size : parameters.getSupportedPreviewSizes()) { if (size.width <= width && size.height <= height) { if (result == null) { result=size; } else { int resultArea=result.width * result.height; int newArea=size.width * size.height; if (newArea > resultArea) { result=size; } } } } return(result); } private Camera.Size getSmallestPictureSize(Camera.Parameters parameters) { Camera.Size result=null; for (Camera.Size size : parameters.getSupportedPictureSizes()) { if (result == null) { result=size; } else { int resultArea=result.width * result.height; int newArea=size.width * size.height; if (newArea < resultArea) { result=size; } } } return(result); } SurfaceHolder.Callback surfaceCallback=new SurfaceHolder.Callback(){ public void surfaceCreated(SurfaceHolder holder) { try { camera.setPreviewDisplay(previewHolder); } catch (Throwable t) { Log.e("PreviewDemo-surfaceCallback", "Exception in setPreviewDisplay()", t); Toast.makeText(CameraLauncherActivity.this, t.getMessage(), Toast.LENGTH_LONG).show(); } } public void surfaceChanged(SurfaceHolder holder,int format, int width,int height) { params = camera.getParameters(); params.setFlashMode(Camera.Parameters.FLASH_MODE_ON); Camera.Size size = getBestPreviewSize(width, height, params); Camera.Size pictureSize=getSmallestPictureSize(params); if (size != null && pictureSize != null) { params.setPreviewSize(size.width, size.height); params.setPictureSize(pictureSize.width, pictureSize.height); camera.setParameters(params); camera.startPreview(); inPreview=true; } } public void surfaceDestroyed(SurfaceHolder holder) { } }; PictureCallback mPicture = new PictureCallback() { @Override public void onPictureTaken(byte[] data, Camera camera) { pictureFile = getOutputMediaFile(); camera.startPreview(); if (pictureFile == null) { return; } try { FileOutputStream fos = new FileOutputStream(pictureFile); fos.write(data); fos.close(); } catch (FileNotFoundException e) { } catch (IOException e) { } } }; static File getOutputMediaFile() { /* yyyy-MM-dd'T'HH:mm:ss.SSSZ */ timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss") .format(new Date()); // file name mediaFile = new File(LoginActivity.mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".jpg"); return mediaFile; } }

Sun over 10 yearseverything works fine just want to do control on continuous click and want to control over exception
-
Kishore over 10 yearsU have to call
startPreview()
aftertakePicture()
-
Melquiades over 10 years1. Please add onPictureTaken() code in your question. 2. When is onTouchEvent() used? 3. Do you want to take picture by pressing button only? 4. Is RuntimeException happening if you press the button once?
-
Sun over 10 years@Melquiades hello bro i posted complete code please check now, getting RuntimeException when pressing multiple times without any break otherwise works fine
-
Melquiades over 10 yearsYou could use flag to limit calling takePicture() to the speed with which your images are being saved. More details in the answer.

-
Sun over 10 yearsbefore takePicture(..) where in onTouchEvent(,..) or capture button ?
-
Sun over 10 yearssuch a amazing solution :) you are just genius.. nice explanation, and one small question what if i also want to use Camera's default button to capture image, like in pudding camera

Melquiades over 9 years@ErumHannan, can you post a new question on SO with your code, and notify me, I'll have a look.

Erum over 9 yearsi have resolved this issue but still after taking pictures in loop i m starting another activity but from new activity when trying to hit back key to move back towards camera activity its crashing my app because onStop has been called and it releases the camera but onStart i have start the camera again but its not working @Melquiades

John over 9 yearsI used Camera.setPreviewCallback()..it worked fine for me...thanks Melquiades
-
Muhammad Babar over 9 yearscalling
camera.startPreview()
beforetakePicture
did the trick! -
Patrick over 5 years@Sun yes, you need to call camera.startPreview() when the saving job is done (eg. in onPictureTaken()), else the camera won't allow you to take another image
