我正在处理一份代码样例,在这份代码中,我需要从图库选择一张图片,虽然代码能够正常工作,但是在从图库选择图片后,我会在OnActivityResult中遇到OutOfMemoryError错误。
我可以获得小图片,但是大图片会出现问题。
下面是我的代码:
try{
Uri selectedImageUri = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImageUri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
cursor.close();
bitmap = BitmapFactory.decodeFile(filePath);
_profileImage.setImageBitmap(bitmap);
_profileImage.setScaleType(ScaleType.FIT_XY);
Constant._addPhotoBitmap=bitmap;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Bitmap resizedbitmap = Bitmap.createScaledBitmap(bitmap, 200, 200, true);
resizedbitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte [] _byteArray = baos.toByteArray();
String base64 = Base64.encodeToString(_byteArray,Base64.DEFAULT);
Constant._addPhotoBase64 = base64;
}catch (OutOfMemoryError e) {
e.printStackTrace();
Constant.showAlertDialog(Constant.errorTitle,
"Image size is too large.Please upload small image.",
DriverProfileScreen.this, false);
} catch (Exception e) {
e.printStackTrace();
}
