fatal exception java.lang.outofmemory when using back camera

Question

i have make a android app for capture image and add a title on image. the app working properly when i use from camera of mobile, but when i use back camera the application has been crashed with error java.lang.outofmemory my code is here

public class MainActivity extends AppCompatActivity {

private ImageView imageResult;
Bitmap processedBitmap;
String photoName;
Uri source1;
private String pictureImagePath = "";
File imgFile;

The back camera has higher image resolution than the front camera. Therefore, direct creation of Bitmap from the byte stream may fail with OutOfMemoryError, especially on devices with small VM heap sizes.

To avoid the error on small VM heap sizes, you can catch the OutOfMemoryError while decoding the bitmap, and if it happens, reduce the image size and try again.

public static Bitmap getBitmapFromStream(Context context, InputStream istr) {
    WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();
    final int REQUIRED_SIZE = display.getWidth();

    istr.mark(Integer.MAX_VALUE);
    BitmapFactory.Options o = new BitmapFactory.Options();
    o.inJustDecodeBounds = true; 
    BitmapFactory.decodeStream(istr, null, o);
    int width_tmp = o.outWidth, height_tmp = o.outHeight;
    int scale = 1;
    while (true){
        if (width_tmp / 2 < REQUIRED_SIZE)
            break;
        width_tmp /= 2;
        height_tmp /= 2;
        scale *= 2;
    }

    while (true) {
        try {
            istr.reset();
            o = new BitmapFactory.Options();
            o.inSampleSize = scale;
            return BitmapFactory.decodeStream(istr, null, o);
        } catch (OutOfMemoryError ex) {
            scale *= 2;
            if (scale >= 32) {
                // Failed
                return null;
            }
        } catch (IOException ex) {
            ex.printStackTrace();
            return null;
        }
    }
}

the error comes when i trying to add text over image click by rename button — svicc computers, Nov 20 '16 at 04:57
It seems that the app has enough memory to keep one bitmap (when you create bm1), but there's not enough memory to keep two bitmaps of same size at once (the second bitmap creation fails with OutOfMemoryError). Consider to reduce the size of the first bitmap before creating a copy of it. Also, try to follow this suggestion: [link](http://stackoverflow.com/questions/14232440/how-to-increase-android-virtual-device-max-heap-size) — vmayorow, Nov 20 '16 at 07:23
You can reduce the bitmap size by using the attribute BitmapFactory.Options.inSampleSize while decoding the stream, see my code above. — vmayorow, Nov 20 '16 at 10:16
