Drawing Text (TimeStamp) Over image captured from Standalone Camera

Drawing Text (TimeStamp) Over image captured from Standalone Camera - java

I have my code below that on click opens the camera, takes a photo, gets the photo from the camera, then puts in into a imageview. However i want to take the image and apply Text (Some sort of time stamp, either the time stamp from the image preferably, or just the system datetime) on the image and save as a jpeg.
If anyone can help me out that would be awesome.

You don't want to put that in the onDraw method, as that's called whenever the View is invalidated (which you don't want).
Just create a method and put that code inside it. Call it after you've gotten the image, like so:
private Bitmap timestampItAndSave(Bitmap toEdit){
Bitmap dest = Bitmap.createBitmap(toEdit.getWidth(), toEdit.getHeight(), Bitmap.Config.ARGB_8888);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String dateTime = sdf.format(Calendar.getInstance().getTime()); // reading local time in the system
Canvas cs = new Canvas(dest);
Paint tPaint = new Paint();
tPaint.setTextSize(35);
tPaint.setColor(Color.BLUE);
tPaint.setStyle(Style.FILL);
float height = tPaint.measureText("yY");
cs.drawText(dateTime, 20f, height+15f, tPaint);
try {
dest.compress(Bitmap.CompressFormat.JPEG, 100, new FileOutputStream(new File(Environment.getExternalStorageDirectory() + "/timestamped")));
} catch (FileNotFoundException e) {
e.printStackTrace();
return null;
}
return dest;
}
I also recommend not saving it to "/sdcard/" but instead use Environment.getExternalStorageDirectory() (already implemented for you)
Edit: Also noticed you're creating a second Bitmap out of myImageBitmap; is that necessary?

This answer explains a nonconform FTP specification in simple FTP, in fact, the server should start with 220 but this library gets an exception.

try {

BufferedInputStream BufInputStream = new BufferedInputStream(FileInpStream);
DBByte = new byte[BufInputStream.available()];
BufInputStream.read(DBByte);
Log.d("DatabaseOperations", "Image Size : " + DBByte.length + " KB");

it's working fine in witth all devices..

First, you assume that Data.getData() is meaningful here. There is no Uri returned by ACTION_IMAGE_CAPTURE, according to the specification. Your options are either to supply EXTRA_OUTPUT (in which case, the image should be where you indicate in that extra), or to get a thumbnail back from Data.getExtra("data"). There may be a few camera apps that do return a Uri. But there are over 8,000 Android device models, with hundreds, if not thousands, of different default camera apps. The user might also be having your request be handled by a third-party camera app. Most camera apps will give you a null value for Data.getData().
Second, even if you get a Uri, you assume that the Uri is known to the MediaStore. That is not required.
Third, even if you get a Uri and it is is known to the MediaStore, you assume that the DATA column is a path to a local file that you can access. This is not required. For example, it might be a path to removable storage, which you cannot access on Android 4.4+.
To address those three problems, use EXTRA_OUTPUT to designate where you want the camera to store the picture, and get rid of getPath() and your dependence upon the Uri.
Fourth, when working with external storage on Android 6.0+, if your targetSdkVersion is 23 or higher, you need to request READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE from the user at runtime. The same holds true for the CAMERA permission.
Fifth, do not have <uses-permission> and <uses-permission-sdk-23> for the same permissions. In your case, use <uses-permission>.

What my application does is, opens up the camera application via an intent. Then loads the image/bitmao into an imageview. Whenever i click the save_btn button it gives me this error. Could anybody tell me why and give me a solution? Thank you.

Just guessing but it seems you store taken image only for local variable
Bitmap image = decodeSampledBitmapFromFile(file.getAbsolutePath(), 1000, 700);
While later in the code you try to store image from class variable with the same name
image.compress(Bitmap.CompressFormat.PNG, 90, fos);

public void storeImage(Bitmap image) {
imageView.buildDrawingCache();
Bitmap bm_img = imageView.getDrawingCache();
File pictureFile = getOutputMediaFile();
if (pictureFile == null) {
Log.d(TAG,
"Error creating media file, check storage permissions: ");// e.getMessage());
return;
}

FileOutputStream fos = new FileOutputStream(pictureFile);
bm_img.compress(Bitmap.CompressFormat.PNG, 90, fos);

Android Camera Application does not display image correctly

I want to make an app that takes a picture with the device's camera, saves the image in the internal memory, and then displays that image in the next Activity. The preview works perfectly, but when I hit the Capture button the app goes to the next activity and only shows a blank white screen. Maybe I'm not writing or reading the file correctly?
Here is the Main Activity:
public class MainActivity extends ActionBarActivity {

// Create an instance of Camera
mCamera = getCameraInstance();
// Create our Preview view and set it as the content of our activity.
CameraPreview mPreview = new CameraPreview(this, mCamera);
FrameLayout preview = (FrameLayout) findViewById(R.id.camera_preview);
preview.addView(mPreview);
// Add a listener to the Capture button
Button captureButton = (Button) findViewById(R.id.button_capture);
captureButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// get an image from the camera
mCamera.takePicture(null, null, mPicture);
}
}
);
}

return b;

}
this code worked showing a pixelated image of what I took picture of (as I'm just decoding it in low quality for testing purposes).
I hope this help you.

Displaying image taken by camera API android

I have been following this tutorial: AndroidHive - working with Camera API to try and enable taking photos in my app. However, I'm getting an error once I press my "take photo button".

Can anybody see where I am going wrong in my code, and what I have to do to fix it?

I created a sample snippet and tested out the mkdirs as shown in your code, it causes similar exception if i removed the permissions
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
Can you please check your manifest to make sure you have these defined.
If above is not the problem, another (unlikely) source of error could be your SD card is running out of space or some permissions restrictions. In this case, i would try the app on android emulator or another device.

This should be added in Manifest to use camera feature:
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:glEsVersion="0x00020000"
android:required="true"/>
