安卓-内存溢出错误。在真实设备上运行时。

android
6

我有一个图片库应用程序，我想从外部存储获取图像。我的应用程序可以在Android模拟器上运行，但在真实设备（HTC OneX）上出现了一些异常。

以下是我的日志记录。

这里是我的代码。

final String[] columns = { MediaStore.Images.Media.DATA,
            MediaStore.Images.Media._ID };
    Cursor image_cursor;
    image_cursor = managedQuery(
            MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null,
            null, null);
    int image_column_index = image_cursor
            .getColumnIndex(MediaStore.Images.Media._ID);
    count = image_cursor.getCount();
    thumbnails = new Bitmap[count];
    arrPath = new String[count];
    try {
        for (int i = 0; i < count; i++) {
            image_cursor.moveToPosition(i);
            int id = image_cursor.getInt(image_column_index);
            int dataColumnIndex = image_cursor
                    .getColumnIndex(MediaStore.Images.Media.DATA);
            thumbnails[i] = MediaStore.Images.Thumbnails.getThumbnail(
                    getApplicationContext().getContentResolver(), id,
                    MediaStore.Images.Thumbnails.MINI_KIND, null);
            arrPath[i] = image_cursor.getString(dataColumnIndex);

        }
    } catch (Exception e) {
        e.printStackTrace();
    }

对不起，我的语言表达可能不太好，请见谅。谢谢。

Your Part: 

count = image_cursor.getCount();
thumbnails = new Bitmap[count];

可能会导致这个问题。为了创建内存高效的位图，您应该使用BitmapOptions。

请尝试使用这个替代:

Bitmap bm;
bm = Bitmap.createScaledBitmap(BitmapFactory.decodeFile(filepath),100, 100, true);
mPicture = new ImageView(context);
mPicture.setImageBitmap(bm);

查看在将图像加载到位图对象中时出现奇怪的内存问题

似乎这两个日志可以给你提示：

无法为缩略图分配内存 content：//media/external/images/thumbnails/300;

.

android.graphics.BitmapFactory.nativeDecodeByteArray（本地方法） 07-25 17:17:49.327：E / AndroidRuntime（3008）：位于 android.graphics.BitmapFactory.decodeByteArray（BitmapFactory.java：552） 07-25 17:17:49.327：E / AndroidRuntime（3008）：位于 android.media.ThumbnailUtils.createThumbnailFromEXIF

您的相册是否包含许多大图片？ 在这种情况下，您的问题不在于游标，而在于位图的内存管理！

此外，您应该在清单中拥有此权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

嗨，Thomas，我遇到了与OP完全相同的问题。我甚至正在加载Micro Kind，但仍然收到很多报告，指示各种设备中存在OutOfMemoryExcpetion。我真的不明白你建议什么。我不应该保留位图数组以包含所有缩略图并在我的Image Adapter中使用它吗？您能解释一下您的解决方案吗？ - idish

我给大家的建议是，尽量不要使用过大的图片，可以使用https://tinypng.com/来压缩图片大小。

其次，在应用程序标签中增加堆大小，如下所示：android:largeHeap="true"

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

和捆绑最大堆大小

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.0'

   .......
   ....

    dexOptions {
        javaMaxHeapSize "4g"

    }
}

我希望这个有所帮助。

将此添加到您的清单文件中：
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

关于内存不足的问题，我曾在使用非常大的图像时遇到过这种情况，请尝试使用较小的图像进行测试..

感谢@user1283633的回答。但是我尝试将您的示例代码添加到我的清单文件中，但对我仍然没有用。 :( - Mimi

添加

 android:largeHeap="true"

在你的清单应用标签中。

这种类型的应用程序真的不建议使用，适用于像PhotoEditor这样非常重的应用程序。 - yshahak
这只是暂时延迟问题，而不能解决根本问题。 - Martin Konecny
