Show Slideshow - Android OutOfMemoryError

Question

I am trying to show a slideshow of images more than 50 images. Whenever I run it though, I get an OutOfMemoryError. My code is:

public class SlideshowActivity extends Activity {

private ViewFlipper myViewFlipper;
int[] image = { R.drawable.one_facebook, R.drawable.two_facebook,
        R.drawable.three_facebook, R.drawable.four_facebook, R.drawable.five_facebook,
        R.drawable.six_facebook, R.drawable.seven_facebook, R.drawable.eight_facebook,
        R.drawable.nine_facebook, R.drawable.ten_facebook, R.drawable.eleven_facebook,
        R.drawable.onetwo_facebook, etc. };

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_slideshow);
    myViewFlipper = (ViewFlipper) findViewById(R.id.myflipper);

    for (int i = 0; i < image.length; i++) {
        ImageView imageView = new ImageView(SlideshowActivity.this);
        imageView.setImageResource(image[i]);
        myViewFlipper.addView(imageView);

    }
    myViewFlipper.setAutoStart(true);
    myViewFlipper.setFlipInterval(1000);
    myViewFlipper.startFlipping();
}

My logcat shows:

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.applications.codegeek.slideshow, PID: 10126 java.lang.OutOfMemoryError: Failed to allocate a 52920012 byte allocation with 4194304 free bytes and 31MB until OOM at dalvik.system.VMRuntime.newNonMovableArray(Native Method) at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method) at android.graphics.BitmapFactory.decodeStream(BitmapFactory.java:620) at android.graphics.BitmapFactory.decodeResourceStream(BitmapFactory.java:455) at android.graphics.drawable.Drawable.createFromResourceStream(Drawable.java:1155) at android.content.res.ResourcesImpl.loadDrawableForCookie(ResourcesImpl.java:720) at android.content.res.ResourcesImpl.loadDrawable(ResourcesImpl.java:571) at android.content.res.Resources.getDrawable(Resources.java:771) at android.content.Context.getDrawable(Context.java:525) at android.widget.ImageView.resolveUri(ImageView.java:856) at android.widget.ImageView.setImageResource(ImageView.java:448) at com.applications.codegeek.slideshow.SlideshowActivity$override.onCreate(SlideshowActivity.java:29) at com.applications.codegeek.slideshow.SlideshowActivity$override.access$dispatch(SlideshowActivity.java) at com.applications.codegeek.slideshow.SlideshowActivity.onCreate(SlideshowActivity.java:0) at android.app.Activity.performCreate(Activity.java:6679) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1118) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2618) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2726) at android.app.ActivityThread.handleRelaunchActivity(ActivityThread.java:4519) at android.app.ActivityThread.-wrap19(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1483) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6119) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:886) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:776)

Any help would be appreciated! Thanks!

why don't you use image loader libraries like glide, picasso etc — Sahil Manchanda

What I found on Glide For Github was that it is useful to show images. I might have understood it wrong though. About picasso I saw some visual examples about it and what I got out of it is that it is useful for collages. I might have understood it wrong and if so, then please tell me what it actualy does. Thank you! — Shreshth Kharbanda

For reduce memory you can use this plugin Android Drawable Importer Plugin

And too..

android:largeHeap="true" in your Manifest It will increase your heap size and avoid the OutOfMemory

Good luck!

Its still not working. I already had the largeHeap in my manifest but I converted all my images to ldpi but it still shows this error. Please help

try with put in your gradle dexOptions android { compileSdkVersion 25 buildToolsVersion '23.0.3' dexOptions { preDexLibraries = false javaMaxHeapSize "4g" }
