android 4.0 以上平台选择图片报错Attempted to access a cursor after it has been closed.

android.database.StaleDataException: Attempted to access a cursor after it has been closed.at android.app.ActivityThread.performResumeActivity(ActivityThread.java:2444)at android.app.ActivityThread.handleResumeActivity(ActivityThread.java:2472)at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1173)at android.os.Handler.dispatchMessage(Handler.java:99)at android.os.Looper.loop(Looper.java:137)at android.app.ActivityThread.main(ActivityThread.java:4424)at java.lang.reflect.Method.invokeNative(Native Method)at java.lang.reflect.Method.invoke(Method.java:511)at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784)at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551)at dalvik.system.NativeStart.main(Native Method)Caused by: android.database.StaleDataException: Attempted to access a cursor after it has been closed.

选择图片后 onActivityResult中的代码如下：

 Uri uri = data.getData();                if (uri != null)                {                    mFilePath = new URIUtils().getPathFromUri(uri);                }

解决办法如注释中的所示。 4.0以上平台会自动关闭cursor

protected String getPath(Uri uri)    {        String filePath = "";        String[] projection = {MediaColumns.DATA };        Cursor cursor = managedQuery(uri,            projection,            null,            null,            null);        if (cursor != null)        {            int columnIndex = cursor.getColumnIndexOrThrow(MediaColumns.DATA);            cursor.moveToFirst();            filePath = cursor.getString(columnIndex);            try            {                //4.0以上的版本会自动关闭 (4.0--14;; 4.0.3--15)                if(Integer.parseInt(Build.VERSION.SDK) < 14)                {                    cursor.close();                }            }catch(Exception e)            {                Log.error(TAG, "error:" + e);            }        }        return filePath;    }
