and code here.

final string[] columns = { mediastore.images.media.data,             mediastore.images.media._id };     cursor image_cursor;     image_cursor = managedquery(             mediastore.images.media.external_content_uri, columns, null,             null, null);     int image_column_index = image_cursor             .getcolumnindex(mediastore.images.media._id);     count = image_cursor.getcount();     thumbnails = new bitmap[count];     arrpath = new string[count];     try {         (int = 0; < count; i++) {             image_cursor.movetoposition(i);             int id = image_cursor.getint(image_column_index);             int datacolumnindex = image_cursor                     .getcolumnindex(mediastore.images.media.data);             thumbnails[i] = mediastore.images.thumbnails.getthumbnail(                     getapplicationcontext().getcontentresolver(), id,                     mediastore.images.thumbnails.mini_kind, null);             arrpath[i] = image_cursor.getstring(datacolumnindex);          }     } catch (exception e) {         e.printstacktrace();     }

sorry language. thanks.

your part: 

count = image_cursor.getcount(); thumbnails = new bitmap[count];

may cause this. creating bitmaps memory-efficient should use bitmapoptions

try this instead:

bitmap bm; bm = bitmap.createscaledbitmap(bitmapfactory.decodefile(filepath),100, 100, true); mpicture = new imageview(context); mpicture.setimagebitmap(bm);

see strange out of memory issue while loading image bitmap object

seems these both logs may give hint:

failed allocate memory thumbnail content://media/external/images/thumbnails/300;

.

android.graphics.bitmapfactory.nativedecodebytearray(native method) 07-25 17:17:49.327: e/androidruntime(3008): @ android.graphics.bitmapfactory.decodebytearray(bitmapfactory.java:552) 07-25 17:17:49.327: e/androidruntime(3008): @ android.media.thumbnailutils.createthumbnailfromexif

does gallery contain lot of big pictures? in case dont have problem cursor memory management when comes bitmaps!

furthermore should have permission in manifest:

<uses-permission android:name="android.permission.write_external_storage"/>
