Answer 1

您是否在回收Bitmap对象？

Bitmap bm = BitmapFactory.decodeFile(strPath);   
imageView.setImageBitmap(bm);

使用以下代码进行回收。

if(bm!=null){
   bm.recycle();
   bm=null;
}

或者在清单应用程序标记中使用以下代码。

android:largeHeap="true"

Answer 2

java.lang.OutOfMemoryError

看起来你的形象太大了。在传递给另一个活动之前缩放图像。

 Bitmap a = (BitmapFactory.decodeFile(picturePath));
  photo = scaleBitmap(a, 200, 150);
  imageView.setImageBitmap(photo);


 public Bitmap scaleBitmap(Bitmap bitmap,int newWidth,int newHeight) {
        Bitmap scaledBitmap = Bitmap.createBitmap(newWidth, newHeight, Config.ARGB_8888);

        float ratioX = newWidth / (float) bitmap.getWidth();
        float ratioY = newHeight / (float) bitmap.getHeight();
        float middleX = newWidth / 2.0f;
        float middleY = newHeight / 2.0f;

        Matrix scaleMatrix = new Matrix();
        scaleMatrix.setScale(ratioX, ratioY, middleX, middleY);

        Canvas canvas = new Canvas(scaledBitmap);
        canvas.setMatrix(scaleMatrix);
        canvas.drawBitmap(bitmap, middleX - bitmap.getWidth() / 2, middleY - bitmap.getHeight() / 2, new Paint(Paint.FILTER_BITMAP_FLAG));

        return scaledBitmap;

    }

我拿这种类型的错误来帮助我
