I'm new to programming, I've been making an app for the last 3 months and learned a few things. But I haven't come across to how to solve this issue. I've been using Parse.com as my server, sending pictures, saving user data etc. With all of this data the app keeps crashing if I open some activities more than a few times, particularly activities with pictures. Now I have compressed the pictures and made them max 400x400 in resolution. But somehow the allocation is out of memory keeps popping up. Does anyone know any methods with which you can solve this? Because when the app crashes in Android Studio the previous memory which was on my phone seems to get deleted (Not all of the cache data).
Thanks.

The code is too long to put it here since it's limited to 30,000 chars
If you are using parse.com and getting the Images from database and converting it to bitmaps it will crash your app..
what you should do is, get the image of the URL from parse.com there is method called..
ParseFile.getUrl();
For that implement the Picasso library, which is perfect solution for loading images from database.
To implement picasso in your app,
compile 'com.squareup.picasso:picasso:2.5.2'
Then get the file from parse database
ParseFile file = getParseFile("ImageColumn");
To load the file
Uri url = Uri.parse(file.getUrl());
then just get context and ..add following passing your file url..
Picasso.with(context)
.load(url) //load from your URL of parseFile
.into(imageView); //set it to your ImageView
Here is the reason, why you should implement this..
Getting Bitmap file will consume so much memory, and it will give you OutOfMemory Exception, which you are getting right now. So instead you just get the URL of file and that's it. Loading image will be dependent on the Internet. so you are saving the memory by not converting every single bit into image. Also you will do in loop for every image will cause your app to crash.
ALSO full tutorial will be available from Official website Picasso Library
