com.android.camera.action.CROP sets wallpaper on M

Question

I'm working on an Android 2.1+ app and trying to take a photo and then send the results of that intent to a crop function. It seems to work on the Sony Ericsson xmp, but when i put it on a Moto Defy, the crop function fails because it is seemingly ignoring the file name i put in for the data, and instead looks at /data/data/com.motorola.gallery/files/temp-wallpaper for some reason. This has the result of the crop function not returning with any data, and the image i just took gets set as the wallpaper image of the phone! Here's some sample code:

public static final String SD_CARD_TEMP_DIR = Environment.getExternalStorageDirectory() + File.separator;
public static final String SD_CARD_TEMP_ORIG = SD_CARD_TEMP_DIR + "origPhoto.jpg";
public static final String SD_CARD_TEMP_CROP = SD_CARD_TEMP_DIR + "croppedPhoto.jpg";

Intent intent = new Intent("com.android.camera.action.CROP");
intent.setDataAndType(Uri.fromFile(new File(Const.SD_CARD_TEMP_ORIG)), "image/*");
intent.putExtra("crop", true);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", 512);
intent.putExtra("outputY", 512);
intent.putExtra("return-data", false);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Const.SD_CARD_TEMP_CROP)));

The output from this is something like this:

INFO/ActivityManager(1242): Starting activity: Intent { act=com.android.camera.action.CROP dat=file:///sdcard/origPhoto.jpg typ=image/* cmp=com.motorola.gallery/.CropImage (has extras) }

WARN/System.err(25672): java.io.FileNotFoundException: /sdcard/croppedPhoto.jpg

Does anyone have any experience with this issue, or ideas for a work around?

Answer 1

I'd stay away from the Intent you're using, because it isn't standard, so may not be supported everywhere,

From the extra-data you're using, I believe you're doing a fixed-size crop, and don't need any user input. This makes the solution quite simple, as long as you don't run out of memory.

1. Load the image via BitmapFactory.decodeFile. You can pass in a BitmapFactory.options object to optionally scale the image at load time.
2. Create a cropped bitmap with Bitmap.createBitmap(Bitmap source, int x, int y, int width, int height)
3. Write it out to disk with Bitmap.compress
