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：

[java] view
plaincopy

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

[java] view
plaincopy

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;

}
