Droid的媒體服務器上死camera.takePicture（）

Question

在摩托羅拉Droid，固件2.1 UPDATE1，內核29年2月9日 - omap1，構建＃ESE81

當試圖拍照，媒體服務器具有分割 故障死亡。

我試過把takePicture放在一個定時器中，並在 攝像機初始化後運行幾秒鐘來檢查競爭條件，但沒有改變。只要 調用Camera.open()不會導致崩潰。此外，致電Camera.open() 會導致我認爲自動對焦電機發出某種滴答聲。打破

代碼：

import android.app.Activity; 
import android.os.Bundle; 

public final class ChopperMain extends Activity { 
    public void onCreate(Bundle savedInstanceState) { 
    try { 
     Camera camera = Camera.open(); 
     catch (Exception e) { 
      e.printStackTrace(); 
     } 
     camera.takePicture(
       new Camera.ShutterCallback() { 
        public void onShutter() { 
         ; 
        } 
       }, 
       new Camera.PictureCallback() { 
        public void onPictureTaken(byte[] data, Camera camera) { 
         ; 
        } 
       }, 
       new Camera.PictureCallback() { 
        public void onPictureTaken(byte[] data, Camera camera) { 
         ; 
        } 
       }, 
      new PictureCallback() { 
       public void onPictureTaken(byte[] data, Camera camera) { 
        System.out.println("Ta da."); 
       } 
      } 
     }); 

    } 
    catch (Exception e) { 
     e.printStackTrace(); 
    } 
    } 
}
