I want to that when a user clicks a button, he can choose gallery or camera, and that the program can retrieve the captured\/picked photo. I tried a couple of things, but nothing seems to work completely. This is how I start the gallery so the user can pick a photo:<\/p>\n

Simon, I have this working for picking from the gallery using this intent:<\/p>\n
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);\nintent.setType(\"image\/*\");\n<\/code><\/pre>\nAnd then handling the choice like this:<\/p>\n
mFilename=null;\n mPath=null;\n\n Uri selectedImage = data.getData();\n final String[] filePathColumn = { MediaColumns.DATA, MediaColumns.DISPLAY_NAME };\n Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);\n\n \/\/ some devices (OS versions return an URI of com.android instead of com.google.android \n if (selectedImage.toString().startsWith(\"content:\/\/com.android.gallery3d.provider\")) \n {\n \/\/ use the com.google provider, not the com.android provider. \n selectedImage = Uri.parse(selectedImage.toString().replace(\"com.android.gallery3d\",\"com.google.android.gallery3d\"));\n }\n\n if (cursor != null) {\n cursor.moveToFirst();\n int columnIndex = cursor.getColumnIndex(MediaColumns.DATA);\n\n \/\/ if it is a picasa image on newer devices with OS 3.0 and up\n if (selectedImage.toString().startsWith(\"content:\/\/com.google.android.gallery3d\"))\n {\n columnIndex = cursor.getColumnIndex(MediaColumns.DISPLAY_NAME);\n if (columnIndex != -1)\n {\n final Uri uriurl = selectedImage;\n \/\/ should do this in a background thread, since we are fetching a large image from the web\n mFilename = getGalleryFile(activity, uriurl);\n }\n }\n else\n {\n \/\/ it is a regular local image file\n String filePath = cursor.getString(columnIndex);\n cursor.close();\n mFilename = filePath;\n }\n }\n \/\/ If it is a picasa image on devices running OS prior to 3.0\n else if (selectedImage != null && selectedImage.toString().length() > 0)\n {\n final Uri uriurl = selectedImage;\n \/\/ should do this in a background thread, since we are fetching a large image from the web\n mFilename = getGalleryFile(activity, uriurl);\n }\n<\/code><\/pre>\nAnd as for the camera part of what you want, what you’re doing looks fine you are just running out of memory creating the Bitmap. You should use BitmapFactory::decodeStream with BitmapFactory.Options set to scale the incoming image to the size of the View you’re going to display it in.<\/p>\n
As explained below, to complete the answer here is getGalleryFile:<\/p>\n
public static String getGalleryFile(Activity activity, Uri url)\n{\n String fileName=null;\n File path;\n\n try {\n \/\/ getCameraStoragePath is a function in my activity\n \/\/ that returns a location where I'm writing files\n \/\/ you could use Environment.getExternalStorageDirectory()\n \/\/ or ....\n path = new File(MyTask.getCameraStoragePath());\n } catch (Exception e1) {\n \/\/ todo: handle exception\n return null;\n }\n\n SimpleDateFormat timeStampFormat = new SimpleDateFormat(\"yyyyMMddHHmmssSS\");\n fileName = \"gallery.\" + timeStampFormat.format(new java.util.Date()) + \".jpg\";\n File out = new File(path, fileName);\n\n try {\n InputStream is = null;\n if (url.toString().startsWith(\"content:\/\/com.google.android.gallery3d\"))\n {\n is=activity.getContentResolver().openInputStream(url);\n }\n else\n {\n is=new URL(url.toString()).openStream();\n }\n\n OutputStream os = new FileOutputStream(out);\n\n byte[] buffer = new byte[1024];\n int len;\n while ((len = is.read(buffer)) != -1)\n {\n os.write(buffer, 0, len);\n }\n\n os.close();\n return out.getAbsolutePath();\n }\n catch (Exception ex)\n {\n \/\/ todo: handle exception\n return null;\n }\n}\n<\/code><\/pre>\n<\/li>\n<\/ol>\nOriginally posted 2013-11-16 20:52:27. <\/small><\/p>","protected":false},"excerpt":{"rendered":"
