Android：java.lang.OutOfMemoryError：无法分配23970828字节的内存，还剩2097152字节和2MB的可用空间，直到OOM。

Careful here 'backgroundtest' did not actually go to drawable-nodpi and will 
be resampled higher, such as 4x or 16x of the original dimensions for high def screens.

Last but not the least....

Try Method One:

Simple Add these lines of code in the gradle file

dexOptions {
        incremental true
        javaMaxHeapSize "4g"
     }

Example:

android {
    compileSdkVersion XX
    buildToolsVersion "28.X.X"

    defaultConfig {
        applicationId "com.example.xxxxx"
        minSdkVersion 14
        targetSdkVersion 19
    }

dexOptions {
        incremental true
        javaMaxHeapSize "4g"
     }
}

*******************************************************************

Method Two:

Add these two lines of code in manifest file...

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

Example:

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:hardwareAccelerated="false"
        android:largeHeap="true"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

It will Work for sure any of these cases.....

解决方案：在您的清单文件中尝试以下内容，并使用Glide库

compile 'com.github.bumptech.glide:glide:3.7.0'

    **Use Glide Library and Override size to less size;**

 if (!TextUtils.isEmpty(message.getPicture())) {
            Glide.with(mContext).load(message.getPicture())
                    .thumbnail(0.5f)
                    .crossFade()
                    .transform(new CircleTransform(mContext))
                    .diskCacheStrategy(DiskCacheStrategy.ALL)
                    .into(holder.imgProfile);
        } 

android:hardwareAccelerated="false"

安卓：硬件加速 = "false"

android:largeHeap="true"

安卓：大内存 = "true"

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

使用此库

  compile 'com.github.bumptech.glide:glide:3.7.0'   

它正在工作，愉快的编码。

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Paint;

import com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool;
import com.bumptech.glide.load.resource.bitmap.BitmapTransformation;


public class CircleTransform extends BitmapTransformation {
    public CircleTransform(Context context) {
        super(context);
    }

    @Override
    protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
        return circleCrop(pool, toTransform);
    }

    private static Bitmap circleCrop(BitmapPool pool, Bitmap source) {
        if (source == null) return null;

        int size = Math.min(source.getWidth(), source.getHeight());
        int x = (source.getWidth() - size) / 2;
        int y = (source.getHeight() - size) / 2;

        // TODO this could be acquired from the pool too
        Bitmap squared = Bitmap.createBitmap(source, x, y, size, size);

        Bitmap result = pool.get(size, size, Bitmap.Config.ARGB_8888);
        if (result == null) {
            result = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);
        }

        Canvas canvas = new Canvas(result);
        Paint paint = new Paint();
        paint.setShader(new BitmapShader(squared, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP));
        paint.setAntiAlias(true);
        float r = size / 2f;
        canvas.drawCircle(r, r, r, paint);
        return result;
    }

    @Override
    public String getId() {
        return getClass().getName();
    }
}

您的应用程序因图像大小（以 MB 或 KB 为单位）过大而崩溃，因此不会为其分配空间。因此，在将图像粘贴到可绘制对象之前，请先缩小其大小。

或者

您可以在 Manifest.xml 文件中的 application 标签中添加以下内容：

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

添加此应用程序后，将不会崩溃。

• 始终在应用程序中使用较小的图像尺寸。
• 如果您在应用程序中添加大尺寸图像，则应添加上述语法，但是应用程序大小将增加。

我也遇到了同样的问题。

和上面大多数人一样，这个问题是由过大的图像引起的。

只要调整一些图像大小，无需更改任何代码。

添加后，我的问题得到了解决。

 dexOptions {
        incremental true
        javaMaxHeapSize "4g"
        preDexLibraries true
        dexInProcess = true
    }

在Build.Gradle文件中

我不是很建议像这样编辑清单

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

这些选项会导致您的应用程序动画效果不流畅。此外，'liveData' 或更改本地数据库（Sqlite、Room）会激活缓慢。这对用户体验不好。

因此，我建议调整大小的位图

以下是示例代码

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)
 }
