Androidカメラのmediaserverが撮影後に消える - エミュレータで動作する

Question

私のArchos 32 Androidデバイスでこのエラーが発生しています。私はこの記事を見つけました：Droid's mediaserver dies on camera.takePicture()

しかし、プレビュー以外の「不足している部分」についてはあまり具体的ではありません。

私のコードは、エミュレータと少なくとも1つの他のドロイドデバイスで動作します。それとも、Archosとの互換性がないのですか、それとも何か不足している可能性がありますか？

Archosには動作するカメラプログラムがありますので、写真を撮るアプリを持つことは可能ですが、私はsdkとの非互換性があると思っています。完全な作業カメラのEclipseプロジェクトはどこでダウンロードできますか？私が見つけることができるのはコードスニペットだけです。ここで

は、デバッグログです：

Archos32も同じ問題を抱えています。あなたはあなたの問題に対する答えを見つけましたか？私はあなたのコードをチェックして、Archos32のメディサーバーも写真を撮ろうとすると死ぬ。

私はあなたのコードを更新しましたが、写真を撮るときにメディアサーバーが死ぬことのないようにしています。私は - 私はカメラのプレビューに使用するプレビューサイズを決定するために特別なことをやっていないよので、これはかなりダウンし&汚れている

public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { 
    // Now that the size is known, set up the camera parameters and begin 
    // the preview. 
    Camera.Parameters parameters = camera.getParameters(); 

     List<Size> previewSizes = parameters.getSupportedPreviewSizes(); 
     Size optimalPreviewSize = previewSizes.get(0); 

    // parameters.setPreviewSize(w, h); // seems to crash if this code is enabled 
    parameters.setPreviewFormat(ImageFormat.JPEG); 
    parameters.setPreviewSize(optimalPreviewSize.width, optimalPreviewSize.height);  

    camera.setParameters(parameters); 
    camera.startPreview(); 
} 

：私は基本的に次のようにPreview.javaを更新しました私が行った変更の結果は、メディアサーバがonShutter（）をクラッシュせず、rawCallback（）とjpegCallback（）も呼び出されるということです。

必要に応じて、Google's CameraPreview API DemoからgetOptimalPreviewメソッドを取得して、画像を撮影するときに使用する「最適な」プレビューサイズを取得できます。

これがうまくいくかどうか教えてください。私は何時間もArchosと戦っ​​ていて、クラッシュせずにカメラを実装しようとしましたが、ついに進歩を遂げました。
