how to correct this error: java.lang.OutOfMemoryError

Question

This is my code:

public void onPictureTaken(byte[] data, Camera camera) {
    Bitmap foto = BitmapFactory.decodeByteArray(data, 0, data.length);
    wid = foto.getWidth();
    hgt = foto.getHeight();

    Bitmap newImage = Bitmap.createBitmap(wid, hgt, Bitmap.Config.ARGB_4444);
    Canvas canvas = new Canvas(newImage);
    canvas.drawBitmap(foto, 0f, 0f, null);
    if (newImage.getWidth() > newImage.getHeight()) {
        Matrix matrix = new Matrix();
        matrix.postRotate(90);
        newImage.createBitmap(newImage, 0, 0, wid, hgt, matrix, true);

    }
}

This is my error:

The error is pretty clear, you're using too much memory I recommend you to check the memory usage of your application and track exactly when this error happens. — Rafael

ost of times this happens due to large bitmap cross the limit of VM heap, so you need to scale down your image or to lower the quality of you image.

To scale image use BitmapFactory.Options.

Bitmap bm = null;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 5;
AssetFileDescriptor fileDescriptor =null;
try {
    fileDescriptor = this.getContentResolver().openAssetFileDescriptor(selectedImage,”r”);
} catch (FileNotFoundException e) {
    e.printStackTrace();
}
finally{
    try {
        bm = BitmapFactory.decodeFileDescriptor(fileDescriptor.getFileDescriptor(), null, options);
        fileDescriptor.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

Or use Bitmap.compress() to lower quality of image.

And you can also follow this conversation to avoid memory error while loading images in Bitmap.

If you are using an emulator you might have a value for VM Heap too low for that emulator instance. Check the Advanced Option in the emulator and try increasing the value for VM Heap. It happened to me that in my phone was working but not in the emulator for the low VM Heap value. Anyway, if you don't have lots of images probably they have a resolution too high.
