I built an activity to take and choose pictures from gallery. I tried to run my App on three different devices, Samsung, Sony and ZTE.
The samsung device is the only device that crashes sometimes, and the error that I'm getting is:
Destroying surface without window.
This message says everything, samsung automatically destroys the surface when I open the camera or gallery, and when I try to go back to my activity, the application crashes because my surface doesn't exists anymore.
I'm trying to fix this error, Thats my function:
private void selectImage() {
final CharSequence[] options = {
translate.translation(language, 27), translate.translation(language, 28), translate.translation(language, 19)

My activity extends AppCompatActivity.
Could you please tell me where is the problem?
Here you have
startActivityForResult(chooserIntent, 2);
and in your onActivityResult method you don't include 2 in your if statement. I think the problem is in that.
Your RequestCode is 2.
Change this:
if (requestCode == 1) {
With this:
if (requestCode == 2) {
I am trying to take photo and let the photo saved in portrait orientation. I could not do so even if I changed the manifest nor the intent's orientation to set it portrait. I Google and tried various ways, but none works. Please assist.

Hi, i have an image uploader, i am uploading image from android gallery to my server. But some photos load horizontally. How can i understand, photo is horizontal or vertical and how do i rotate.
It look below, after upload :
to check the orientation of an image
ExifInterface ei = new ExifInterface(photoPath);
int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
switch(orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
break;
case ExifInterface.ORIENTATION_ROTATE_180:
break;
// etc.
}
To rotate the image use
private Bitmap rotateImage(Bitmap source, float angle) {
Bitmap bitmap = null;
Matrix matrix = new Matrix();
matrix.postRotate(angle);
try {
bitmap = Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(),
matrix, true);
} catch (OutOfMemoryError err) {
err.printStackTrace();
}
return bitmap;
}
try this code:
public static Bitmap getOriententionBitmap(String filePath){
Bitmap myBitmap = null;
try
{
File f = new File(filePath);
ExifInterface exif = new ExifInterface(f.getPath());
int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
int angle = 0;
if (orientation == ExifInterface.ORIENTATION_ROTATE_90) {
angle = 90;
}
else if (orientation == ExifInterface.ORIENTATION_ROTATE_180) {
angle = 180;
}
else if (orientation == ExifInterface.ORIENTATION_ROTATE_270) {
angle = 270;
}
Matrix mat = new Matrix();
mat.postRotate(angle);
Bitmap bmp1 = BitmapFactory.decodeStream(new FileInputStream(f), null, null);
myBitmap = Bitmap.createBitmap(bmp1, 0, 0, bmp1.getWidth(), bmp1.getHeight(), mat, true);
}
catch (IOException e) {

}

}

I inserted on my application a section to take and select pictures, but unfortunately, sometimes, when I take a photo or I select a picture to save on my server, the application crashes. Is really weird because my application only crashes sometimes.
I'm receiving this error:

How can I check if the photo is null and prevent my application from crashing?

What happened?
I am sending you the code for taking picture and take the picture into your application.
First of all add the below intend:
