android: GLWallpaperService causing green screen

由 南楼画角 提交于 2019-12-06 11:56:27
问题 I am trying to create a live wallpaper using opengl (<2.0). I imported and tried to run Robert Green's GLWallpaperService and Example here (using Eclipse SDK). My phone is a Huwei Ascend Android 2.1. I already know it can run other opengl LWPs. When I run the package, it just produces a solid green screen, and no shapes or anything. Ive researched it alot and still cant figure out why this is happening. I read a few times that the namespaces have to be changed to my package. But still no luck

问题 I want to implement a double tap event for a Android live wallpaper. Sadly, I couldn´t find any specific code how to do that. At the moment I´ve found a workarround using the onTouchEvent-method of the Engine-class: public void onTouchEvent(MotionEvent event) { long time = android.os.SystemClock.currentThreadTimeMillis(); if(((time - mLastTouchTime) < 500) && ((time - mLastTouchTime) > 100)) { if(!mIsPlayed && mSound) { mIsPlayed = true; int sound = R.raw.hell; if(mTheme.equals("rose")) sound

Communicate with a WallpaperService

由 江枫思渺然 提交于 2019-12-06 05:14:06
Is there any way to directly communicate with a WallpaperService from an Activity ? It doesn't look like I can use the normal service communication classes because the onBind method is declared final in the WallpaperService class I'm extending. Worth noting that I'm referring to my WallpaperService not any . Any workarounds if this isn't possible? My solution was to use local sockets. I created an instance of a LocalServerSocket in the constructor of my wallpaper's Engine . Here's a quick implementation. Server runs on a separate thread and is directly tied to the lifecycle of MyEngine . The

由 时光毁灭记忆、已成空白 提交于 2019-12-05 21:33:59
问题 I am trying to make an App in which I need to use camera live feed as a background. (I know its a stupid thing to do but can't help, its a client demand). I have tried doing it using SurfaceView but no success so far. So far whatever I found on Stack Overflow are more of a guesses or directions how to do it but no real time examples or code help is out there. It would be great if someone who has done this before share a piece of code with Stack Overflow users like me. 回答1: Take a look here:

Create alpha gradient on image to create fade effect

由 元气小坏坏 提交于 2019-12-05 05:29:22
问题 How can I apply an alpha gradient on an image so that it fades linearly? Right now, I'm creating rectangles of unit width and using it to draw the bitmap with a paint object with alpha value being changed in a loop. I only did it since I couldn't think of anything else. So a neater way would be better. Bitmap bitmap = BitmapFactory.decodeStream(is); Bitmap bmp = Bitmap.createScaledBitmap(bitmap, 100, 151, true)); bitmap.recycle(); Rect Rect1 = new Rect(0, 0, 100, 100); Rect Rect2 = new Rect
