i've really frustased to solve my problem, i have an application that using camera, when camera capture a photo, it will display on activity, when i'm not using cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mPhotoUri);
photo will display on activity, but the name and path file is not like what i wanted. i'm using galaxy tab for compiling it, i have follow tutorial to solve my problem from here , here and here but my application still force close and eror, this is my code :
{
File sdCard = Environment.getExternalStorageDirectory();
File path = new File (sdCard.getAbsolutePath() + "/android/data/spaj_foto");
path.mkdir();
File file = new File (path,"spaj_foto.png");
String filePath ="/android/data/spaj_foto/spaj_foto.png";
try {
file.createNewFile();
} catch (IOException e) {}
mPhotoUri = Uri.fromFile(file);
values.put(MediaStore.Images.ImageColumns.DATA, file.getPath());
mPhotoUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mPhotoUri);
startActivityForResult(cameraIntent,TAKE_PHOTO_CODE );
}
activityresult method :
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
image_spaj.setImageBitmap(photo);
// CALL THIS METHOD TO GET THE URI FROM THE BITMAP
Uri tempUri = getImageUri(getApplicationContext(), photo);
// CALL THIS METHOD TO GET THE ACTUAL PATH
File finalFile = new File(getRealPathFromURI(tempUri));
// System.out.println(mImageCaptureUri);
}
}
public String getRealPathFromURI(Uri mPhotoUri) {
Cursor cursor = getContentResolver().query(mPhotoUri, null, null, null, null);
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
this is my logcat says:
