Choose the most appropriate decode method based on your image data source. These methods attempt to allocate memory for the constructed bitmap and therefore can easily result in an OutOfMemory exception. Each type of decode method has additional signatures that let you specify decoding options via the BitmapFactory.
Canvas is the place or medium where perfroms/executes the operation of drawing, and Bitmap is responsible for storing the pixel of the picture you draw.
The parameter to onDraw() is a Canvas object that the view can use to draw itself. The Canvas class defines methods for drawing text, lines, bitmaps, and many other graphics primitives. You can use these methods in onDraw() to create your custom user interface (UI).
A drawable resource is a general concept for a graphic that can be drawn to the screen and which you can retrieve with APIs such as getDrawable(int) or apply to another XML resource with attributes such as android:drawable and android:icon . There are several different types of drawables: Bitmap File.
Move your image in the (hi-res) drawable to drawable-xxhdpi. But in app development, you do not need to use large image. It will increase your APK file size.
The solution is to move the image from drawable/ folder to drawable-xxhdpi/ folder, as also others have mentioned.
But it is important to also understand why this somewhat weird suggestion actually helps:
The reason is that the drawable/ folder exists from early versions of android and is equivalent to drawable-mdpi. When an image that is only in drawable/ folder is used on xxhdpi device, the potentially already big image is upscaled by a factor of 3, which can then in some cases cause the image's memory footprint to explode.
This solution worked for me.
Add these lines in your Manifest application tag
android:largeHeap="true"
android:hardwareAccelerated="false"
I had the same problem. If you try to upload an image that is too large on some low resolution devices, the app will collapse. You can make several images of different sizes (hdpi, xxdpi and more) or simply use an external library to load images that solve the problem quickly and efficiently. I used Glide library (you can use another library like Picasso).
panel_IMG_back = (ImageView) findViewById(R.id.panel_IMG_back);
Glide
.with(this)
.load(MyViewUtils.getImage(R.drawable.wallpaper)
.into(panel_IMG_back);
Turns out the problem was the main image that we used on our app at the time. The actual size of the image was too large, so we compressed it. Then it worked like a charm, no loss in quality and the app ran fine on the emulator.
