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; }给我老师的人工智能教程打call！http://blog.csdn.net/jiangjunshow
