Hi, I have made two versions of my desktop game on android using andengine. One uses a normal image background and the other has augmented reality as the background.
The links to both the games are: https://market.android.com/details?id=com.raghavsood.speedball https://market.android.com/details?id=com.raghavsood.speedballar One common problem in both the games is that sometimes the moving ball disappears. This in itself does not cause a crash or anything like that but spoils the game as the ball is kind of the point. The next few problems are related only to the augmented reality one (link 2) 1) When the game is started sometimes it displays the ACRA toast saying my app has crashed but then continues straight on and opens the game which works fine. 2) Sometimes the game crashes on pressing the back button, opening it after pressing the home button. The two stacktraces below appear in both the problems. java.lang.RuntimeException: Fail to connect to camera service at android.hardware.Camera.native_setup(Native Method) at android.hardware.Camera.<init>(Camera.java:264) at android.hardware.Camera.open(Camera.java:239) at com.raghavsood.speedballar.CameraPreviewSurfaceView.surfaceCreated(CameraPreviewSurfaceView.java:45) at android.view.SurfaceView.updateWindow(SurfaceView.java:552) at android.view.SurfaceView.dispatchDraw(SurfaceView.java:350) at android.view.ViewGroup.drawChild(ViewGroup.java:1644) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1373) at android.view.View.draw(View.java:6883) at android.widget.FrameLayout.draw(FrameLayout.java:357) at android.view.ViewGroup.drawChild(ViewGroup.java:1646) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1373) at android.view.View.draw(View.java:6883) at android.widget.FrameLayout.draw(FrameLayout.java:357) at com.android.internal.policy.impl.PhoneWindow$DecorView.draw(PhoneWindow.java:1874) at android.view.ViewRoot.draw(ViewRoot.java:1524) at android.view.ViewRoot.performTraversals(ViewRoot.java:1260) at android.view.ViewRoot.handleMessage(ViewRoot.java:1861) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:3729) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:507) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:874) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:632) at dalvik.system.NativeStart.main(Native Method) And java.lang.RuntimeException: setParameters failed at android.hardware.Camera.native_setParameters(Native Method) at android.hardware.Camera.setParameters(Camera.java:914) at com.raghavsood.speedballar.CameraPreviewSurfaceView.surfaceChanged(CameraPreviewSurfaceView.java:62) at android.view.SurfaceView.updateWindow(SurfaceView.java:549) at android.view.SurfaceView.dispatchDraw(SurfaceView.java:348) at android.view.ViewGroup.drawChild(ViewGroup.java:1644) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1373) at android.view.View.draw(View.java:6883) at android.widget.FrameLayout.draw(FrameLayout.java:357) at android.view.ViewGroup.drawChild(ViewGroup.java:1646) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1373) at android.view.View.draw(View.java:6883) at android.widget.FrameLayout.draw(FrameLayout.java:357) at com.android.internal.policy.impl.PhoneWindow$DecorView.draw(PhoneWindow.java:1862) at android.view.ViewRoot.draw(ViewRoot.java:1522) at android.view.ViewRoot.performTraversals(ViewRoot.java:1258) at android.view.ViewRoot.handleMessage(ViewRoot.java:1859) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:130) at android.app.ActivityThread.main(ActivityThread.java:3683) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:507) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) at dalvik.system.NativeStart.main(Native Method) CameraPreviewSurfaceView.java reads (Lines 62 and 45 from the above stacktraces are in bold.): package com.raghavsood.speedballar; import java.io.IOException; import org.anddev.andengine.util.Debug; import android.content.Context; import android.hardware.Camera; import android.view.SurfaceHolder; import android.view.SurfaceView; class CameraPreviewSurfaceView extends SurfaceView implements SurfaceHolder.Callback { private final SurfaceHolder mSurfaceHolder; private Camera mCamera; public CameraPreviewSurfaceView(final Context pContext) { super(pContext); this.mSurfaceHolder = this.getHolder(); this.mSurfaceHolder.addCallback(this); this.mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void surfaceCreated(final SurfaceHolder pSurfaceHolder) { * this.mCamera = Camera.open();* try { this.mCamera.setPreviewDisplay(pSurfaceHolder); } catch (IOException e) { Debug.e("Error in Camera.setPreviewDisplay", e); } } public void surfaceDestroyed(final SurfaceHolder pSurfaceHolder) { this.mCamera.stopPreview(); this.mCamera.release(); this.mCamera = null; } public void surfaceChanged(final SurfaceHolder pSurfaceHolder, final int pPixelFormat, final int pWidth, final int pHeight) { final Camera.Parameters parameters = this.mCamera.getParameters(); parameters.setPreviewSize(pWidth, pHeight); * this.mCamera.setParameters(parameters);* this.mCamera.startPreview(); } } I have removed extra white lines so if you count the lines it will be off. Any suggestions on resolving these problems?
