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);

解决方案尝试在您的清单文件和使用滑翔库

编译的com.github.bumptech.glide:滑翔: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 =“虚假”

android：largeHeap=“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">

使用这个库

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

工作快乐编码

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();
    }
}

其他回答

实际上，你可以在你的清单中添加这些行android:hardwareAccelerated="false"， android:largeHeap="true"，这是在某些情况下工作，但要注意，代码的另一部分可能与此争论。

<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">

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。

OR

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。

如果上传图片，请尝试降低图片质量，这是位图的第二个参数。这就是我案例中的解。以前是90，然后我尝试了60(正如下面的代码所示)。

Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
finalBitmap.compress(Bitmap.CompressFormat.JPEG,60,baos);
byte[] b = baos.toByteArray();

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.

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.....
