Android: . lang。OutOfMemoryError:未能分配23970828字节分配，2097152空闲字节和2MB直到OOM

我想显示的位图图像在ImageView从sd卡已经存储。运行后，我的应用程序是崩溃和得到OutOfMemoryError错误:

(. lang。OutOfMemoryError:未能分配23970828字节分配，2097152空闲字节和2MB直到OOM)

我不知道为什么它没有记忆。我觉得我的图片太大了，所以我试着改变它。

Iterator<String> it = imageArray.iterator();
while (it.hasNext()) {
  Object element = it.next();
  String objElement = element.toString();
  Log.e("objElement ", " = " + objElement);
  final ImageView imageView = new ImageView (getContext());
  final ProgressBar pBar = new ProgressBar(getContext(), null, 
                                           android.R.attr.progressBarStyleSmall);
  imageView.setTag(it);
  pBar.setTag(it);

  imageView.setImageResource(R.drawable.img_placeholder);
  pBar.setVisibility(View.VISIBLE);

  if (objElement.endsWith(mp3_Pattern)) {
     Log.e("Mp3 ", " ends with ");
     pBar.setVisibility(View.GONE);
     imageView.setImageResource(R.drawable.audio_control);
  }
  if (objElement.endsWith(png_Pattern)) {
     Bitmap bitmap = BitmapFactory.decodeFile(objElement);
     int size = Math.min(bitmap.getWidth(), bitmap.getHeight());
     int x = (bitmap.getWidth() - size) / 2;
     int y = (bitmap.getHeight() - size) / 2;
     Bitmap bitmap_Resul = Bitmap.createBitmap(bitmap, x, y, size, size);
     Log.e("bitmap_Resul "," = "+ bitmap_Resul);

     if (bitmap_Resul != bitmap) {
        bitmap.recycle();
     }
     imageView.setImageBitmap(bitmap_Resul);
     Log.e("png_Pattern ", " ends with ");
     Log.e(" bitmap "," = " + bitmap);
  }

  holder.linearLayout.addView(imageView);
  holder.linearLayout.addView(pBar);

I suppose you want to use this image as an icon. As Android is telling you, your image is too large. What you just need to do is scale your image so that Android knows which size of the image to use and when according to screen resolution. To accomplish this, in Android Studio: 1. right click on the res folder, 2. select Image Asset 3. Select icon Type 4. Give the icon a name 5. Select Image on Asset Type 6. Trim your image Click next and finish. In your xml or source code just refer to the image which will now be located either in the layout or mipmap folder according to asset type selected. The error will go away.

你的应用程序崩溃，因为你的图像大小(MB或KB)太大了，所以它没有分配空间。所以在将图像粘贴到drawable中之前，减小大小。

您可以在Manifest.xml的应用程序标签中添加Following

 android:hardwareAccelerated="false"
    android:largeHeap="true"
    android:allowBackup="true"

添加此应用程序后不会崩溃。

在应用程序中总是使用较小尺寸的图像。如果你在应用程序中添加大尺寸的图像，你应该添加以上syntex，但应用程序大小将增加。

我是一个机器人开发的新手，但我希望我的解决方案有帮助，它在我的条件下完美工作。我使用Imageview并将其背景设置为“src”，因为我试图制作一帧动画。我得到了同样的错误，但当我试图编码这个它工作

int ImageID = this.Resources.GetIdentifier(questionPlay[index].Image.ToLower(), "anim", PackageName);
            imgView.SetImageResource(ImageID);
            AnimationDrawable animation = (AnimationDrawable)imgView.Drawable;
            animation.Start();
            animation.Dispose();

stream = activity.getContentResolver().openInputStream(uri);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.RGB_565;

bitmap = BitmapFactory.decodeStream(stream, null, options);
int Height = bitmap.getHeight();
int Width = bitmap.getWidth();
enter code here
int newHeight = 1000;
float scaleFactor = ((float) newHeight) / Height;
float newWidth = Width * scaleFactor;

float scaleWidth = scaleFactor;
float scaleHeight = scaleFactor;
Matrix matrix = new Matrix();
matrix.postScale(scaleWidth, scaleHeight);
resizedBitmap= Bitmap.createBitmap(bitmap, 0, 0,Width, Height, matrix, true);
bitmap.recycle();

然后在Appliaction标签中添加largeheapsize="true

对我来说，问题是我的.png文件被解压缩成内存中的一个非常大的位图，因为图像的维度非常大(尽管文件大小很小)。

所以修复是简单地调整图像的大小:)

使用像Picasso或Glide这样的图像加载库。使用这些库将在将来防止崩溃。
