Mainstream Android screen resolutions For Android game development, we have to think about compatibility with Android tablets like the iPhone. Apple needs to consider the compatibility between iPad, iPhone 3GS, and iPhone 4 screens, which is no exception for Android game development, more models are considered. In general, we may only consider QVGA, HVGA, WVGA, FWVGA, and DVGA. However, if we leave the phone blank, we may use a tablet like WSVGA's 1024x576 and WXGA's 1280x768. QVGA = 320*240; WQ

the west side is a complex mountains composed of rough rock edges. The lava flow was formed before 280, and formed by the cooling and solidification of the lava from the waist of The Rock Mountain. The black lava extension of the fan-type has a spreading length of about 3Km and a maximum of about 1Km. Up to now, no plants have been grown and stored in good condition. Therefore, the lava flow in Iwate is designated as a special natural commemorative place. Take a 30-minute walk along the lava fl

So ③ we continue to transport coal until the remaining 1000 tons of coal, and then directly go. This seems to be three rounds. The first round of the combined operation of 2000 tons of coal to the transfer station, consuming 1000 tons, because 5x = 1000, so the first round took 200 meters. The second round of combined ope
