  1. POOutOfMemoryError of Bitmap in Android
    text
    copied!<p>I am developing one demo application in which I am playing so many images(Bitmaps). I am using Global Bitmap object for display same image in to more than one Activity. But using that I am geting OutOfMemoryError while I am trying to create Bitmap using Bitmap.createBitmap(...). I tried using <a href="http://developer.android.com/training/displaying-bitmaps/load-bitmap.html#load-bitmap" rel="nofollow">this code</a> but still I am getting same error and it is crashing my application and through the OutOfMemoryError.</p> <p>I am stuck on this. Can anyone has any solution to avoid this.??</p> <p>Thanks in advance.</p> <p><strong>I am getting bitmap after cropping the image so that I am using below code for decode the bitmap size.</strong></p> <pre><code>public static Bitmap loadFromBitmap( Context context, Bitmap b, int maxW, int maxH ) throws IOException { final BitmapFactory.Options options = new BitmapFactory.Options(); Bitmap bitmap = null; options.inScaled = false; options.inPreferredConfig = Bitmap.Config.RGB_565; options.inJustDecodeBounds = true; BufferedInputStream stream = null; ByteArrayOutputStream outstream = new ByteArrayOutputStream(); b.compress(CompressFormat.JPEG, 100, outstream); InputStream is = new java.io.ByteArrayInputStream(outstream.toByteArray()); stream = new BufferedInputStream(is, 16384 ); if ( stream != null ) { options.inSampleSize = calculateInSampleSize( options, maxW, maxH ); stream = null; stream = new BufferedInputStream(is, 16384 ); } else { return null; } options.inDither = false; options.inJustDecodeBounds = false; options.inPurgeable = true; bitmap = BitmapFactory.decodeStream( stream, null, options ); if ( bitmap != null ) bitmap = BitmapUtils.resizeBitmap( bitmap, maxW, maxH ); return bitmap; } public static int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) { // Raw height and width of image final int height = options.outHeight; final int width = options.outWidth; int inSampleSize = 1; if (height &gt; reqHeight || width &gt; reqWidth) { // Calculate ratios of height and width to requested height and width final int heightRatio = Math.round((float) height / (float) reqHeight); final int widthRatio = Math.round((float) width / (float) reqWidth); // Choose the smallest ratio as inSampleSize value, this will guarantee // a final image with both dimensions larger than or equal to the // requested height and width. inSampleSize = heightRatio &lt; widthRatio ? heightRatio : widthRatio; } return inSampleSize; } </code></pre> <p>Error:</p> <pre><code>02-21 15:32:31.160: E/AndroidRuntime(2951): FATAL EXCEPTION: main 02-21 15:32:31.160: E/AndroidRuntime(2951): java.lang.OutOfMemoryError 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.graphics.BitmapFactory.decodeStream(BitmapFactory.java:483) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.graphics.BitmapFactory.decodeResourceStream(BitmapFactory.java:351) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.graphics.BitmapFactory.decodeResource(BitmapFactory.java:374) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.graphics.BitmapFactory.decodeResource(BitmapFactory.java:404) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.app.Activity.performCreate(Activity.java:4465) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1092) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1924) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1985) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.app.ActivityThread.access$600(ActivityThread.java:127) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1151) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.os.Handler.dispatchMessage(Handler.java:99) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.os.Looper.loop(Looper.java:137) 02-21 15:32:31.160: E/AndroidRuntime(2951): at android.app.ActivityThread.main(ActivityThread.java:4447) 02-21 15:32:31.160: E/AndroidRuntime(2951): at java.lang.reflect.Method.invokeNative(Native Method) 02-21 15:32:31.160: E/AndroidRuntime(2951): at java.lang.reflect.Method.invoke(Method.java:511) 02-21 15:32:31.160: E/AndroidRuntime(2951): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) 02-21 15:32:31.160: E/AndroidRuntime(2951): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) 02-21 15:32:31.160: E/AndroidRuntime(2951): at dalvik.system.NativeStart.main(Native Method) </code></pre>
