android photography album access to image clipping error solution

This is calling the camera

	public static File getImageFromCamer(Context context, File cameraFile,
			int REQUE_CODE_CAMERA, Intent intent) {
		intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
		File fileDir = HelpUtil.getFile(context, "/Tour/user_photos");
		cameraFile = new File(fileDir.getAbsoluteFile() + "/"
				+ System.currentTimeMillis() + ".jpg");
		intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(cameraFile));
		((Activity) context).startActivityForResult(intent, REQUE_CODE_CAMERA);
		return cameraFile;
	}

Here I return 1 file object, because this is needed in the project, you can not really write, just pass 1 Uri object

Here is the call album

public static void getImageFromPhoto(Context context, int REQUE_CODE_PHOTO) {
		Intent intent = new Intent(Intent.ACTION_PICK, null);
		intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
				"image/*");
		((Activity) context).startActivityForResult(intent, REQUE_CODE_PHOTO);
 
	}

And then, of course, OnActivityResult calling Activity

	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		if (resultCode == RESULT_OK) {
			switch (requestCode) {
			case ConstantUtil.REQUE_CODE_CAMERA:
				uri = Uri.fromFile(cameraFile);
				PhotoUtil.startPhotoZoom(context, uri,
						ConstantUtil.REQUE_CODE_CROP);
				break;
			case ConstantUtil.REQUE_CODE_PHOTO:
				if (null != data) {// To unselect a pointer that does not report null 
					uri = data.getData();
					PhotoUtil.startPhotoZoom(context, uri,
							ConstantUtil.REQUE_CODE_CROP);
				}
				break;
			case ConstantUtil.REQUE_CODE_CROP:
				if(uri==null){
					break;
				}
				cropBitmap=HelpUtil.getBitmapFromUri(uri,context);
				if (cropBitmap != null) {
					iv_headphoto.setImageBitmap(cropBitmap);
 
					baos = new ByteArrayOutputStream();
					cropBitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
					headPicString = new String(Base64.encode(
							baos.toByteArray(), 0));
					UploadPic(headPicString);
				}
 
				break;
			default:
				break;
			}
		}

And, of course, the shearing that you care about

public static void startPhotoZoom(Context context, Uri uri,
			int REQUE_CODE_CROP) {
		int dp = 500;
 
		Intent intent = new Intent("com.android.camera.action.CROP");
		intent.setDataAndType(uri, "image/*");
		//  The following crop=true It's set on Intent Set to display VIEW Can be cut 
		intent.putExtra("crop", "true");
		intent.putExtra("scale", true);//  Go to the dark side 
		intent.putExtra("scaleUpIfNeeded", true);//  Go to the dark side 
		// aspectX aspectY  It's the ratio of width to height 
		intent.putExtra("aspectX", 1);// The output is X Ratio of directions 
		intent.putExtra("aspectY", 1);
		// outputX outputY  Is cropped picture width and height, do not change the following figures, will be stuck 
		intent.putExtra("outputX", dp);// The output X Directional pixels 
		intent.putExtra("outputY", dp);
		intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
		intent.putExtra("noFaceDetection", true);
		intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
		intent.putExtra("return-data", false);// Set to return no data 
 
		((Activity) context).startActivityForResult(intent, REQUE_CODE_CROP);
	}

Many blogs set "ES28en-ES29en" to true and then get the data from onActivityResult via ES32en.getParcelableExtra ("data"), but the value of the variable dp should not be too large or your program will die. Here also is the place where I have a problem, in most of the high-end mobile phone there is no problem with that, but a lot of low with the mobile phone is a bit hold not to live, directly abnormalities, including our domestic man also failed to hold m 3, so I suggest you don't pass return data big data, data is no problem, said to us when shear pictures use Uri this thing as far as possible to help us.

Here are 1 of the parameters that we used to do the cropping

Exta Options Table for image/* crop:

SetExtra	DataType	Description
crop	String	Signals the crop feature
aspectX	int	Aspect Ratio
aspectY	int	Aspect Ratio
outputX	int	width of output created from this Intent
outputY	int	width of output created from this Intent
scale	boolean	should it scale
return-data	boolean	Return the bitmap with Action=inline-data by using the data
data	Parcelable	Bitmap to process, you may provide it a bitmap (not tested)
circleCrop	String	if this string is not null, it will provide some circular cr
MediaStore.EXTRA_OUTPUT ("output")	URI	Set this URi to a File:///, see example code

Finally, the method of obtaining bitmap through Uri is pasted for everyone

public static Bitmap getBitmapFromUri(Uri uri,Context mContext)
	 {
	 try
	 {
	  //  read uri Where the picture is 
	  Bitmap bitmap = MediaStore.Images.Media.getBitmap(mContext.getContentResolver(), uri);
	  return bitmap;
	 }
	 catch (Exception e)
	 {
	  e.printStackTrace();
	  return null;
	 }
	 }
