Question

我正在为Sony Xperia M C1905建造一个相机应用程序用户按一个按钮拍照然后保存当我在autoFocusCallback

之外调用takePicture（）时问题开始

这是索尼特有的问题还是我在这里做错了什么？

这是logcat输出：

以下是相关代码：

public PictureCallback jpgCallback = new PictureCallback() {            
    @Override
    public void onPictureTaken(byte[] data, Camera camera) {
    // do processing here
    }
};

// Sony Xperia M device constantly crash when takepicture is called from outside AutoFocusCallback
public AutoFocusCallback autoFocusCB = new AutoFocusCallback() {        
    public void onAutoFocus(boolean success, Camera camera) {
        if (success) {
            Globals.myCamera.takePicture(null, null, jpgCallback);
        } else {

        }
    }
};

此代码有效：

public void camerabuttonClicked(View v) {
    Globals.myCamera.setPreviewCallback(null);      
    Globals.myCamera.autoFocus(autoFocusCB);
}

此代码不断崩溃应用程序：

public void camerabuttonClicked(View v) {
    Globals.myCamera.stopPreview();     
    Globals.myCamera.takePicture(null, null, jpgCallback); // MainActivity.java:221
}

我还在三星Galaxy S2上测试了这个代码，它没有这个问题。我从哪里调用takePicture（）并不重要。

索尼Xperia M takePicture（）总是崩溃
