java - 简单的相机代码导致装有 Android V 5.01 的 Nexus4 重启

Question

这个问题花了我很长时间，网上搜索也没有帮助。我编写了一个简单的相机应用程序，仅处理相机预览，代码附在下面。在 Nexus4 (V 5.01) 上运行此代码会导致设备在 1m 到 30m 的随机时间范围后重新启动。我不能说这次重启是由于相机本身或正在运行的 Android 版本中的错误造成的，因为“Camera HDR Studio”和“Barcode Scanner”应用程序运行没有问题。

下面是代码，为了简化，我删除了所有不需要的检查代码和相机释放。

XML:-

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/camera_preview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_weight="1">

    <SurfaceView
      android:id="@+id/camerasurfaceview"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"/>

</FrameLayout>

Java 代码:-

import java.io.IOException;
import android.hardware.Camera;
import android.os.Bundle;
import android.app.Activity;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.WindowManager;

public final class MyActivity extends Activity implements SurfaceHolder.Callback, Camera.PreviewCallback
{
    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
       super.onCreate(savedInstanceState);          
       getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
       setContentView(R.layout.activity_credit_reader);

       SurfaceView SV = (SurfaceView) findViewById(R.id.camerasurfaceview);
       SurfaceHolder mHolder = SV.getHolder();
       mHolder.addCallback(this);
    }

    public void surfaceCreated(SurfaceHolder holder){}
    public void surfaceDestroyed(SurfaceHolder holder){}

    public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) 
    {
       try 
       {
           Camera m_camera ;
           m_camera = Camera.open() ;
           m_camera.setPreviewDisplay(holder);
           m_camera.setPreviewCallback(this);
           m_camera.startPreview();
       }
       catch (IOException e) 
       {
           e.printStackTrace();
       }
   }

   @Override
   public void onPreviewFrame(byte[] data, Camera camera)
   {
       // any processing for "byte[] data".
       double rr = 0 ;
       for(int y = 0 ; y < data.length ; y++)
       {
           rr += Math.sqrt(Math.sqrt((double)(data[y])));
           rr = Math.sin(rr);
           if(data[y] > 128)
               data[y] = (byte)Math.min(255.0, rr) ;
       }
   }
}

在 Nexuses(至少 4 和 10)更新到 Android L 后，我遇到了类似的问题。它看起来像是固件错误且无法解决(Nexus 10 更新并修复了此问题，但 Nexus 4 仍在重新启动并且相机停止响应)。您可以尝试内置相机应用程序 - 它也有同样的问题。
