LED手电筒不会对三星Galaxy Nexus的工作

问题描述

我有以下问题：我的手电筒的应用程序工作正常，在我的三星Galaxy S2，但遗憾的是没有对三星GALAXY Nexus（问题：手电筒忽略按钮 - 点击 - >无反应，没有光，没有崩溃，也不例外）。我读过LED手电筒Galaxy Nexus的控制由什么API？这里的计算器，但它并没有帮助我，因为我的问题仍然occures。这是我的code-片段来控制光：

I've got the following problem:My Flashlight app works fine on my Samsung Galaxy S2 but unfortunately not on the Samsung Galaxy Nexus (problem: flashlight ignores the button-click -> no reaction, no light, no crash, no exception). I've read "LED flashlight on Galaxy Nexus controllable by what API?" here in stackoverflow but it did not help me since my problem still occures.This is my code-snippet to control the light:

final Button FlashLightControl = (Button)findViewById(R.id.ledbutton);
FlashLightControl.setOnClickListener(new Button.OnClickListener()
{
        public void onClick(View arg)
        {
            if(camera != null)
            {
                //in case light is on we will turn it off
                parameters = camera.getParameters();
                parameters.setFlashMode(Parameters.FLASH_MODE_OFF);
                camera.setParameters(parameters);
                camera.stopPreview();
                camera.release();
                camera = null;
            }
            else
            {
                // light is off - we turn it on
                camera = Camera.open();
                parameters = camera.getParameters();
                parameters.setFlashMode(Parameters.FLASH_MODE_TORCH);
                camera.setParameters(parameters);
                camera.startPreview();
            }
        }});

任何想法？出于完整性的 - 这些是我加入的Andr​​oidManifest.xml权限：

Any ideas? For the sake of completeness - these are the permissions I added to the Androidmanifest.xml:

    <uses-feature android:name="android.hardware.camera.flash" />
<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>

有人能帮助？

我有同样的问题，并通过使用具有1像素的宽度和高度1px的表面观解决了这个问题。

I had the same problem and solved it via using Surface View having 1px width and 1px height
