Android Native App , Download Images Bitmap without Memory Leaks

Hi all,

I am developing an android native app, I developed a Listview that will display images(640x640 each image), I want to download these images as Bitmaps, what is the best way to do so.

I implemented a libarary com.nostra13.universalimageloader

Universal Image loader library, but on some phones I am getting out of Memory error.

Could anyone help, Thank you.

Hello,

Are you trying to grab the images from the internet? If so, you may have forgotten to close the inputStream which would explain the out of memory error.

If you are, the inputStream should look like this:

while(true){ // Infinite loop, can only be stopped by a "break" statement
    nextCharacter = reader.read(); // read() without parameters returns one character
    if(nextCharacter == -1) {// A return value of -1 means that we reached the end
    break;
    }
    responseData += (char) nextCharacter; // The += operator appends the character to the end of the string
}

Here, the "break" will break the loop. Otherwise, your loop will just carry on running forever!
