Someone will definitely be curious about the three places where images are placed on Android, such as drawable-hdpi, drawable-mdpi, drawable-ldpi, where images are placed in Android.
Certainly in the mind will think, put in which all can, as long as is in the Android in the Res directory drawable in the line, the system will find itself.
A friend of his heart would surely have made a man out of it. I used to drawable-hdpi, drawable-mdpi, drawable-ldpi These three have also understood, but only literally, did not really understand thoroughly, until today I was a little bit deeper understanding.
drawable-hdpi look at his word name must know he is placed high-resolution pictures, drawable-mdpi to place a medium-resolution picture, DRAWABLE-LDPI place a low-resolution picture.
Most people put pictures in the drawable-mdpi. At first I thought it would be all right to place the picture in any of the three, but today I know it.
Placing a picture in a drawable-mdpi when the resolution is lower than 480*800 will have no effect, but when the resolution is 420*800 or above it can be problematic.
Your phone screen is so big but he will stretch the picture, and when the picture is loaded it makes you feel that the screen is not actually size, and if you put the picture in drawable-hdpi, the problem doesn't exist.
