java.lang.outofmemoryerror 安卓设置运行内存

我想在已存储的SD卡中显示ImageView中的Bitmap图像.运行后我的应用程序崩溃并导致OutOfMemoryError错误:

(java.lang.OutOfMemoryError:无法分配带有2097152个空闲字节的23970828字节分配和2MB直到OOM)

我不知道或为什么它的内存不足.我认为我的图像尺寸非常大,所以我试图改变它.

Iterator 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);
