Android：內存不足3240016字節分配

Question

我總是面臨這個問題。通過了很多相同的問題（即this pdf,link,link等）。由於我在Android中仍然天真，任何人都可以幫我解決這個問題嗎？

注：

這個問題來了，當我試圖填充我的列表視圖中的任何多種活動。

Answer 1

Android對單個應用程序爲自己分配多少內存的限制非常嚴格。儘管設備上有可用的內存，但並不意味着操作系統會給你。所以你幾乎沒有運氣。這裏有一些你可以做的事情：

1. 使用更高效的數據表示，不需要這麼大的分配。也許你可以在設備外部的Web服務上壓縮/預處理數據。

2. 如果這不是一個選項，您可以構建自己的平臺映像並更改每個應用程序的內存限制設置。 Look here for more information.

3. 如果（2）不適合您。你可以寫一個本地庫，它將爲你保存數據。內存限制僅適用於Java/Dalvik分配。本地代碼可以做任何想要的事情。

Answer 2

decodedByteImage = BitmapFactory.decodeByteArray(decodeStringImage, 0, decodeStringImage.length); 

ImageLoader的推薦。 https://github.com/nostra13/Android-Universal-Image-Loader

Answer 3

您使用的每個位圖在memroy中花費4mb。您可以通過以下方法使用調整大小的位圖。

private Bitmap decodeBitmap(int targetWidth, int targetHeight) throws IOException { 
    final BitmapFactory.Options opts = new BitmapFactory.Options(); 
    opts.inJustDecodeBounds = true; 
    BitmapFactory.decodeStream(getAssets().open("frog.jpg"), null, opts); 

    opts.inSampleSize = getBitmapSampleSize(opts, targetWidth, targetHeight); 

    opts.inJustDecodeBounds = false; 

    return BitmapFactory.decodeStream(getAssets().open("frog.jpg"), null, opts); 
} 

private int getBitmapSampleSize(BitmapFactory.Options opts, int targetWidth, int targetHeight) { 
    final int width = opts.outWidth; 
    final int height = opts.outHeight; 
    Log.d("tag", "bitmap's size is " + width + ", " + height); 
    int inSampleSize = 1; 

    if (height > targetHeight || width > targetWidth) { 
     if (width > height) { 
      inSampleSize = (int) Math.floor((float)height/(float)targetHeight); 
     } else { 
      inSampleSize = (int) Math.floor((float)width/(float)targetWidth); 
     } 
    } 
    Log.d("tag", "target size is " + targetWidth + ", " + targetHeight); 
    Log.d("tag", "inSampleSize is " + inSampleSize); 
    return inSampleSize; 
} 

Answer 4

您可以嘗試將此行添加到清單文件中。它將爲您的應用程序分配大內存。
