This evening starting from 22 o'clock has been over there to test the photo flashback situation, really tangled! Then another project was built to re-test, found that the new project has not been the case of the flash back. So I started uninstalling the project and found that there was no flash back after the reinstallation. After uploading about 3-4 photos, we started to flash back. So finally find out the root cause of the flash is not enough memory!

Finally Kung Fu is not a conscientious, and found the problem lies. Still find the problem is the most important, put the code below.

First, upload some core class libraries to get a root path.

 Public class uploadimage {    //  get the SD card root directory address and create the image parent directory file object and file object;    Private Static String file_str = environment.getexternalstoragedirectory (). GetPath ();      Public Static New File (file_str + "/rzproject");}

If a button has been clicked, a selection box pops up first.

/*** Select photos! */Private voidSetphotos () {NewAlertdialog.builder (mainactivity. This). Settitle ("Hint"). Setmessage ("Please choose how to get Pictures"). Setnegativebutton ("Cancel",NewDialoginterface.onclicklistener () {@Override Public voidOnClick (Dialoginterface arg0,intarg1)                {Arg0.cancel (); }}). Setpositivebutton ("Take pictures",NewDialoginterface.onclicklistener () {@Override Public voidOnClick (Dialoginterface Dialog,intID) {Takephotos (); }}). Setneutralbutton ("Albums",NewDialoginterface.onclicklistener () {@Override Public voidOnClick (Dialoginterface Dialog,intwhich)                {Selectphotos (); }}). Show ();}

That format is really uncoordinated! Forget it, stick to the code!

PrivateString Fileimagename;Private Static Final intPhoto_graph = 1;Private Static Final intPhoto_select = 2;Private voidTakephotos () {//Verify that the SD card is properly installed:    if(Environment.MEDIA_MOUNTED.equals (Environment. Getexternalstoragestate ())) {//The parent directory is created first, and if the parent directory does not exist when a new file is created, the parent directory must be created before creating a new file.         if(!UploadImage.mars_file.exists ())        {UploadImage.mars_file.mkdirs (); } Intent Intent=NewIntent (mediastore.action_image_capture); Fileimagename= Uploadimage.mars_file + "/" +Viewutil.getnewguid ()+ ". jpg"; File Newfile_go=NewFile (fileimagename);        Intent.putextra (Mediastore.extra_output, Uri.fromfile (Newfile_go)); //jump to the photo screen;Startactivityforresult (Intent, photo_graph); } Else {        //viewutil.showtoast ("SD card not Found", false);    }}/*** Choose from albums **/Private voidSelectphotos () {Intent Intent=NewIntent (intent.action_get_content); Intent.settype ("Image/*"); Startactivityforresult (Intent, Photo_select);}

Next is the callback function after selecting the image.

@Overrideprotected voidOnactivityresult (intRequestcode,intResultCode, Intent data) {    Super. Onactivityresult (Requestcode, ResultCode, data); if(Requestcode = = Photo_graph && ResultCode = =RESULT_OK)        {Showprogressdialog (r.string.phots_string); NewImagethread (Fileimagename). Start (); } Else if(Requestcode = = Photo_select && ResultCode = =RESULT_OK) {String path=Viewutil.getphotospath (data);    Copyphotos (path); }   }

There should still be a way to take pictures, which has not been studied for the time being. Temporarily skipped!
