我想从Gallery中选择图像并将其复制到SDCard中的其他文件夹中.

从图库中选择图像的代码

Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
    photoPickerIntent.setType("image/*");
    startActivityForResult(photoPickerIntent, REQUEST_CODE_CHOOSE_PICTURE_FROM_GALLARY);

我在content://media/external/images/media/681onActivityResult上获得了这个URI.

我想复制图片,

形成 path ="content://media/external/images/media/681

到 path = "file:///mnt/sdcard/sharedresources/ SD卡中的Android这条道路.

这该怎么做？

我试图将null值传递给execute(); 在android 4.0中AsyncTask的方法它显示错误"方法执行(Integer [])对于类型"是不明确的"但相同的代码与android 2.2代码工作正常代码是:

public class AllianceAnalysisDemoActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    new AsynPageLoader().execute(null);
}


public class AsynPageLoader extends AsyncTask<Integer, Integer, Bitmap> {

    @Override
    protected void onPreExecute() {
        // progressBar.setVisibility(VISIBLE);
    }

    @Override
    protected Bitmap doInBackground(Integer... params) {

        return null;
    }

    @Override
    protected void onPostExecute(Bitmap result) {
        if (result != null && result.getHeight() > 0
                && result.getWidth() > 0) {

        }else {

        }
    }

} …

我在eclipse中在Android + Google App Engine中创建了一个微笑应用程序.我正在尝试在Google App Engine上部署该应用,但它会显示错误消息

我正在尝试通过相机将图像捕获上传到服务器.服务器发送响应代码= 200但Image不上传到服务器.

代码是:

    {
            if (isPhoto)

            else
                message = "Uploading Shared Items " + (i + 1) + " of " + count;

            progressCount = (i * 1000)/count;

我想创建这样的服务,当Android设备上安装任何新应用程序时启动.那么如何知道安装在Android设备上的任何应用程序,是否有任何Intent事件被触发？
