我暂停相机应用后手机崩溃,然后切换回来拍照.这只发生在我的三星Galaxy S上,在我的Huwai设备上它完全有效.我找到了导致错误的代码行.不幸的是,这些行很有用,所以我不能剥离它们:

public void surfaceDestroyed(SurfaceHolder holder) { // <14>
        Log.d(TAG,"surfaceDestroyed()");
        if(this.camera != null){
            camera.stopPreview();
            // the next two lines lead to the error after switching back to the app and taking a picure
            camera.release();
            this.camera = null;
        }
    }

不幸的是我没有得到堆栈跟踪.我得到的只是:

我在这里有我的Activity课程:

public class CameraActivity extends Activity {

private Camera mCamera;
private CameraPreview mPreview;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //      startCamera();
}

public void startCamera() {
    setContentView(R.layout.camera_view);
    mCamera = getCameraInstance();// Open Camera
    mPreview = new CameraPreview(this,mCamera);// Goto Another Class

    FrameLayout preview = (FrameLayout) findViewById(R.id.camera_preview);
    preview.setLayoutParams(new FrameLayout.LayoutParams(400,400));

    //Declare Frame in which camera will be opened
    preview.addView(mPreview); // show this class into frame

}

protected void onResume() {
    super.onResume();
    Log.d("Print","resume()");
    startCamera();
}

public static Camera getCameraInstance() {
    Camera c = null;
    try …
