Java.lang.RuntimeException: setParameters failed to execute in Camera Api

I am developing Camera overly application, using camera api for preview and overlay effects. I get a power error on some mobile phones, and this does not happen with other mobile phones.

My code is:

parameters = camera.getParameters(); List<Size> sizes = parameters.getSupportedPreviewSizes(); Size optimalSize = getOptimalPreviewSize(sizes, w, h); parameters.setPreviewSize(optimalSize.width, optimalSize.height); parameters.setColorEffect(Camera.Parameters.EFFECT_SOLARIZE); setCameraDisplayOrientation(MainActivity.this,0, camera); camera.getParameters(); camera.setParameters(parameters);

These are the call stacks I receive

  java.lang.RuntimeException: setParameters failed at android.hardware.Camera.native_setParameters(Native Method) at android.hardware.Camera.setParameters(Camera.java:1046) at com.androidpixels.watercamera.MainActivity.surfaceChanged(MainActivity.java:1241) at android.view.SurfaceView.updateWindow(SurfaceView.java:575) at android.view.SurfaceView.updateWindow(SurfaceView.java:407) at android.view.SurfaceView.dispatchDraw(SurfaceView.java:352) at android.view.ViewGroup.drawChild(ViewGroup.java:1644) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1373) at android.view.ViewGroup.drawChild(ViewGroup.java:1644) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1373) at android.view.ViewGroup.drawChild(ViewGroup.java:1644) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1373) at android.view.View.draw(View.java:6936) at android.widget.FrameLayout.draw(FrameLayout.java:357) at com.android.internal.policy.impl.PhoneWindow$DecorView.draw(PhoneWindow.java:1917) at android.view.ViewRoot.draw(ViewRoot.java:1530) at android.view.ViewRoot.performTraversals(ViewRoot.java:1266) at android.view.ViewRoot.handleMessage(ViewRoot.java:1868) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:130) at android.app.ActivityThread.main(ActivityThread.java:3693) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:507) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:907) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:665) at dalvik.system.NativeStart.main(Native Method)

Android camera settings vary between devices. you need to make sure that the device supports the parameter that you are trying to set before setting it, see this Camera SetParameters Doc

You can request supported parameters:

  • Get the object Parameters: Camera.Parameters params = mCamera.getParameters();

  • Then query this object for a specific parameter, such as PreviewSize:

    params.getSupportedPreviewSizes ()
