Outofmemoryerror Imageview

I have a problem with imageview, i have 77 picture jpg and have 126 quote text, just simple app i want is i want show all quote with background picture and i use viewflipper so whe

Solution 1:

I recommend to create an 2 dim array containing the comment and the path to the picture. For the pictures, create a thumbnail. I am doing it with this code

BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 4;
pic = BitmapFactory.decodeFile(strPicPath, options);
image.setImageBitmap(pic);

I am not sure if image gets smaller with bigger inSampleSize... You'll have to try

image is in XML:

<ImageViewandroid:id="@+id/imagePreview"android:layout_width="134dp"android:layout_height="146dp"android:layout_weight="0.36"android:onClick="imageClick" /></LinearLayout>

I use the on click method to open the image in the gallery but you can do zoom or what you want.

Solution 2:

To fix OutOfMemory you should do something like that:

this is a code i ref it's work good check it

BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 8;
Bitmap preview_bitmap=BitmapFactory.decodeStream(is,null,options);

This inSampleSize option reduces memory consumption.

Here's a complete method. First it reads image size without decoding the content itself. Then it finds the best inSampleSize value, it should be a power of 2. And finally the image is decoded.

//decodes image and scales it to reduce memory consumptionprivate Bitmap decodeFile(File f){
    try {
        //Decode image size
        BitmapFactory.Optionso=newBitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(newFileInputStream(f),null,o);

        //The new size we want to scale tofinalint REQUIRED_SIZE=70;

        //Find the correct scale value. It should be the power of 2.int scale=1;
        while(o.outWidth/scale/2>=REQUIRED_SIZE && o.outHeight/scale/2>=REQUIRED_SIZE)
            scale*=2;

        //Decode with inSampleSize
        BitmapFactory.Optionso2=newBitmapFactory.Options();
        o2.inSampleSize=scale;
        return BitmapFactory.decodeStream(newFileInputStream(f), null, o2);
    } catch (FileNotFoundException e) {}
    returnnull;
}

Solution 3:

Try putting this code before changing the image:

imageView.getDrawable().getBitmap().recycle();
