surfaceview

I am using a SurfaceView and a rendering thread to develop a game based on structure like LunarLander. However, I faced many problems, and here I want to point them all out. I wish anyone who want to develop a game won't need to struggle with them anymore. And anyone who have a better idea of the structure can share their experiences, because I am still new to android and is eager to learn :) [1] The function thread.start() should not be called more than once. Many articles mentioned to create a thread when surface is created, in order to render again after activity paused using the method :

I have a MediaPlayer in a Fragment which retains its instance on configuration changes. The player is playing a video loaded from my assets directory. I have the scenario set up with the goal of reproducing the YouTube app playback where the audio keeps playing during the configuration changes and the display is detached and reattached to the media player. When I start the playback and rotate the device, the position jumps forward about 6 seconds and (necessarily) the audio cuts out when this happens. Afterwards, the playback continues normally. I have no idea what could be causing this to

I've been studying Android especially View system. I have a question differences between them but there is no documents or references in my mother language. So I want to know from you guys. TextureView A TextureView can be used to display a content stream. Such a content stream can for instance be a video or an OpenGL scene.

The scenario is the following: I have an activity RunTrainingWorkoutsView that uses XML layout _run_workout.xml_ with some labels that are updated by CountDownTimer . Works fine... Now, apart from labels that are updated every sec by onTick() callback method of CountDownTimer object I want to add a custom surface view to my _run_workout.xml layout_ that would draw some arcs updated by the same onTick() method every second... my run_workout.xml: <training.timer.CounterClockView android:id="@+id/counter_clock_surface" android:layout_width="300dp" android:layout_height="240dp"> </training.timer

I am trying to make an app using canvas and a surfaceview, and I am worrying that in the future I would have many problems with it because I am not sure if the canvas is proportional with every device. currently I can only use my emulator since my phone's usb cable doesn't work(I know.. I have to get a new one..). anyways, i would like to know if the canvas would transfer my coordinates and make everything proportional, what I mean by that is that if i have something in point a, lets say (10, 10) on a device that the screen of it is 100 X 100 (this is just an example for easy calculation) it
