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);

把这个加到申请舱单上?android: largeHeap = " true "

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.

我真的不建议像这样编辑清单

android:hardwareAccelerated=“错误”，android:largeHeap=“真实”

这些选项会导致应用程序的动画效果不流畅。此外，“liveData”或更改本地DB(Sqlite, Room)激活缓慢。这不利于用户体验。

所以我推荐RESIZE位图

下面是示例代码

fun resizeBitmap(source: Bitmap): Bitmap {
      val maxResolution = 1000    //edit 'maxResolution' to fit your need
      val width = source.width
      val height = source.height
      var newWidth = width
      var newHeight = height
      val rate: Float

            if (width > height) {
                if (maxResolution < width) {
                    rate = maxResolution / width.toFloat()
                    newHeight = (height * rate).toInt()
                    newWidth = maxResolution
                }
            } else {
                if (maxResolution < height) {
                    rate = maxResolution / height.toFloat()
                    newWidth = (width * rate).toInt()
                    newHeight = maxResolution
                }
            }
            return Bitmap.createScaledBitmap(source, newWidth, newHeight, true)
 }

我得到了下面的错误

"E/art: throws OutOfMemoryError "分配47251468字节失败分配16777120个空闲字节和23MB直到OOM"

在AndroidManifest.xml中添加android:largeHeap="true"后，我消除了所有错误

<application
    android:allowBackup="true"
    android:icon="@mipmap/guruji"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:largeHeap="true"
    android:theme="@style/AppTheme">

使用滑动库和覆盖大小，以减少大小;

Glide.with(mContext).load(imgID).asBitmap().override(1080, 600).into(mImageView);

2016-02-16 08:16:09

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。
