I'm running Ubuntu 16.04. And on Android Studio when I try to run my application in the emulator I get the following error:

I did have to run through some hoops to get my emulator working however, needed to create a sym-link so I can run the emulator on AMD. Not sure if this is part of the problem. And for the life of me I cannot figure why it continues to do this. In my group there are others who emulate the project just fine on the same emulated phone and SDK.
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);
This issue can be resolved by 3 methods as follows:
Method 1:
By adding image into a res/drawable-nodpi folder (By doing this it will not pre-scale your image).
Method 2:
Generate all dpi(hdpi,ldpi,mdpi,xhdpi,xxhdpi,xxxhdpi) of image and add to drawable folder. (This process will increase APK size).
Method 3:
Add image to drawable/drawable-xxhdpi folder.
All these methods are verified.
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.
For this error was like others said a big image(1800px X 900px) which was in drawable directory, I edited the image and reduced the size proportionally using photoshop and it worked...!!
If you don't want your image to be pre-scaled you can move it to the res/drawable-nodpi/ folder.

if you use Picasso change to Glide like this.
Remove picasso
Picasso.get().load(Uri.parse("url")).into(imageView)
Change Glide
Glide.with(context).load("url").into(imageView)
More efficient Glide than Picasso draw to large bitmap
I also had this issue when i was trying to add a splash screen to the android app through the launch_backgrgound.xml . the issue was the resolution. it was too high so the images memory footprint exploded and caused the app to crash hence the reason for this error. so just resize your image using a site called nativescript image builder so i got the ldpi,mdpi and all the rest and it worked fine for me.
I just created directory drawable-xhdpi(You can change it according to your need) and copy pasted all the images to that directory.
This can be an issue with Glide. Use this while you are trying to load to many images and some of them are very large:
Glide.load("your image path")
.transform(
new MultiTransformation<>(
new CenterCrop(),
new RoundedCorners(
holder.imgCompanyLogo.getResources()
.getDimensionPixelSize(R.dimen._2sdp)
)
)
)
.error(R.drawable.ic_nfs_default)
.into(holder.imgCompanyLogo);
}
Try using an xml or a vector asset instead of a jpg or png.
The reason is quite obvious in the exception name itself i.e. the resolution of the resource is too large to render.
You can png to xml using online tools like https://svg2vector.com/ OR add your image to drawable-xxhdpi folder.
Solution for Picasso is add Transformation for resize image.
class ResizeTransformation(private val maxSize: Int) : Transformation {
override fun transform(source: Bitmap?): Bitmap? {
var result:Bitmap? = null
if (source != null) {
var width = source.width
var height = source.height
val bitmapRatio = width.toFloat() / height.toFloat()
if (bitmapRatio > 1) {
width = maxSize;
height = (width / bitmapRatio).toInt()
} else {
height = maxSize;
width = (height * bitmapRatio).toInt()
}
result = Bitmap.createScaledBitmap(source, width, height, true)
source.recycle()
}
return result
}
override fun key() = "resize()"
}
Use:
Picasso.get()
.load(url)
.transform(ResizeTransformation(2400)) //FHD+ resolution
.into(view)
Convert your all png formats into webs format. You can do it by Android Studio.
i am using glide for showing loading images, and in my app image will be changed frequently, is there any option for clear cache when new image or image will be edited otherwise load old one?
try this:
whenever image changes the cache will remove
Glide.with(YourActivity.this)
.load(Uri.parse(image_url))
.diskCacheStrategy(DiskCacheStrategy.NONE)
.skipMemoryCache(true)
.into(mImage);
refer this link hope it will help you to resolve this issue
I have used the below code to achieve the same that you have mentioned in the description above.
fun ImageView.loadUrl(url: String) {
var requestOptions = RequestOptions()
requestOptions.signature(ObjectKey(System.currentTimeMillis()))
Glide.with(this).load(url).apply(requestOptions).into(this)
}
It's just an extension for the imageview and you need to use below way wherever you want this in your app.
imageView.loadUrl(url)
I have save image path in database and image save in folder. Displaying image in list view app is stuck and slow. I not understand how to resolve this issue.
I am using following code:
strContactImage = customer.getPhotoPath();
Bitmap decodedImage = BitmapFactory.decodeFile(strContactImage);
customerImage.setImageBitmap(decodedImage);
customer.getPhotoPath() gets folder photo path image, and displays it properly, but when I added more than 20 records app slows down, and gets stuck.
Use uri to set image into image view instead of decoding into bitmap...
strContactImage = customer.getPhotoPath();
Uri uri=Uri.fromFile(new File(strContactImage));
// Set the uri into ImageView
customerImage.setImageURI(uri);
It might help you...
You can use any image caching library, here is the example of Picasso
strContactImage = customer.getPhotoPath();
Picasso.with(context)
.load(new File(strContactImage))
.into(customerImage);
check the size of the images they can effect the memory and make the app stuck and slow if they are take a lot of memory !
to fix that
take a look here
Load a Scaled Down Version into Memory
and check the method calculateInSampleSize() and decodeSampledBitmapFromResource()
it’s not worth loading a 1024x768 pixel image into memory if it will eventually be displayed in a 128x96 pixel thumbnail in an ImageView.
and you can use library that can help you to load image and they will take care about the memory usage and loading the image into Your View
Library :
Picasso
example :
Picasso.with(context).load(file).into(imageview);
Glide
example :
GlideApp.with(context).load(file).into(imageview);

I'm working on an app that allows changing theme. To achieve that, I need to change background in java.
I created imageView and tried to set background as imageView.
I was using this code:
ImageView imgViewBackground =(ImageView) findViewById(R.id.imageViewBackground);
int ID = getResources().getIdentifier("imagebackground", "drawable", getPackageName());
imgViewBackground.setImageResource(ID);
but the app crashes after 20-30 seconds of usage.
I also tried this, but the app crashes on startup:
RelativeLayout layout =(RelativeLayout)findViewById(R.id.imageViewBackground);
layout.setBackgroundResource(R.drawable.imagebackground);
Is there an effective way to change background directly, and not through imageView in java?
Why not simply do this:
ImageView imgViewBackground =(ImageView) findViewById(R.id.imageViewBackground);
imgViewBackground.setImageResource(R.drawable.imagebackground);
P.S: An image by the name imagebackground must be present in the drawable folder.
My requirement is that i need to change all the images and colors at run time. But as far as i know the images needs to be in the drawable folders. So my question is, after i export the apk file will i be able to download the images from a server through the application and set them as the images in the app?
For an example, lets say i have a linear layout with a background image which is in my drawable folder. After installing the app in the device can i download an image from a server and set it as the background of the linear layout?
I hope i have made the question clear. Any help would be greatly appreciated.
Thanks in advance.
try this one (i posted my version for FrameLayout, Imageview should be similar):
String myJpgPath = "/sdcard/picture.jpg";
Bitmap image_b = BitmapFactory.decodeFile(myJpgPath);
final BitmapDrawable image_d = new BitmapDrawable(image_b);
final FrameLayout main = (FrameLayout) findViewById(R.id.main_view);
main.setBackgroundDrawable(image_d);
