Loading a full width and height image

``` <ImageView android:id="@+id/bg" android:layout_width="match_parent" android:layout_height="match_parent" android:adjustViewBounds="true" android:scaleType="centerCrop" android:src="@drawable/bg" /> ``` @drawable/bg is 1600 * 1800 (W * H) I tried using ``` BitmapFactory.decodeResource(getResources(), R.drawable.bg, options); ``` using `inSampleSize` Here are the logs: ``` 02-05 05:32:05.841: E/screenWidth in px =(876): 768 02-05 05:32:05.841: E/screenheight in px =(876): 1184 02-05 05:32:05.841: E/screenDensity =(876): 2.0 02-05 05:32:05.841: E/screenDensityDpi =(876): 320 02-05 05:32:05.841: E/decodeSampledBitmapFromResource reqWidth =(876): 768 02-05 05:32:05.851: E/decodeSampledBitmapFromResource reqHeight =(876): 1184 02-05 05:32:05.921: E/decodeSampledBitmapFromResource imageHeight =(876): 1800 02-05 05:32:05.921: E/decodeSampledBitmapFromResource imageWidth =(876): 1600 02-05 05:32:05.921: E/decodeSampledBitmapFromResource imageType =(876): image/jpeg 02-05 05:32:05.951: E/calculateInSampleSize: inSampleSize =(876): 1 02-05 05:32:09.291: E/dalvikvm-heap(876): Out of memory on a 44441616-byte allocation. 02-05 05:32:09.391: E/AndroidRuntime(876): FATAL EXCEPTION: main 02-05 05:32:09.391: E/AndroidRuntime(876): Process: com.example.splash, PID: 876 02-05 05:32:09.391: E/AndroidRuntime(876): java.lang.OutOfMemoryError 02-05 05:32:09.391: E/AndroidRuntime(876): at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.graphics.BitmapFactory.decodeStream(BitmapFactory.java:587) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.graphics.BitmapFactory.decodeResourceStream(BitmapFactory.java:422) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.graphics.BitmapFactory.decodeResource(BitmapFactory.java:445) 02-05 05:32:09.391: E/AndroidRuntime(876): at com.example.splash.SecondActivity.decodeSampledBitmapFromResource(SecondActivity.java:103) 02-05 05:32:09.391: E/AndroidRuntime(876): at com.example.splash.SecondActivity.onCreate(SecondActivity.java:57) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.app.Activity.performCreate(Activity.java:5231) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1087) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2159) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2245) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.app.ActivityThread.access$800(ActivityThread.java:135) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1196) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.os.Handler.dispatchMessage(Handler.java:102) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.os.Looper.loop(Looper.java:136) 02-05 05:32:09.391: E/AndroidRuntime(876): at android.app.ActivityThread.main(ActivityThread.java:5017) 02-05 05:32:09.391: E/AndroidRuntime(876): at java.lang.reflect.Method.invokeNative(Native Method) 02-05 05:32:09.391: E/AndroidRuntime(876): at java.lang.reflect.Method.invoke(Method.java:515) 02-05 05:32:09.391: E/AndroidRuntime(876): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:779) 02-05 05:32:09.391: E/AndroidRuntime(876): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:595) 02-05 05:32:09.391: E/AndroidRuntime(876): at dalvik.system.NativeStart.main(Native Method) ``` The thing is, for a device which has height 1184 the inSampleSize will be 1 (Hence no change) So, its kind of useless going through all this process and the same OOM occurs. This single screen shows that it takes 44 mb of memory, which I got using: ``` long totalMem = Runtime.getRuntime().totalMemory(); ``` If I set image src as @null, the above value is 3 mb Is this a reliable way to find the memory usage by the app? Please help me how to load such high resolution images without any OOM.
