Px: The pixel of the screen.In: inchesMM: mmPT: LB, 1/72 inchDP: an abstract unit based on density. If a screen of DPI is displayed, 1dp = 1px.Dip: equivalent to DPSP: similar to DP, but it also scales according to the user's font size preference.We recommend that you use SP as the unit of text, and dip for others.
The following is an overview of the relationship between DIP and PX:

Px :( pixels): the pixels on the screen. Different devices have the same display effect. Generally, we use hvga to represent 320x480 pixels, which is usually used.
Dip: (device independent pixels), device independent pixels. This is related to the hardware of the device. We recommend that you use this method to support wcga, hvga, and qvga, instead of pixels. Equivalent to DP.
DP: an abstract unit

of video quality. In addition, complex algorithms often require a large amount of computing, and developers are always limited by the MIPs budget of Digital Signal Processor (DSP.When an application does not require the highest level of video quality, you can use a Scaling Algorithm in the hardware to implement de-interlacing. This technology can transform the format from to and detach the interface to other hardware, which is particularly helpful for saving valuable dspmips resources. Surprisi
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.
