Question

我有一个图库应用程序，我正在尝试从外部存储中获取图像。我的应用程序可以在Android模拟器上运行但在真实设备（HTC OneX）上我有一些例外。

我的日志猫在这里。

我的代码在这里。

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。感谢。

Answer 1

你的部分：

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

可能导致这种情况。要创建位图内存效率，您应该使用BitmapOptions

请尝试此：

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

请参阅 Strange out of memory issue while loading an image to a Bitmap object

似乎这两个日志可能会给你提示：

无法为缩略图分配内存内容：//媒体/外部/图像/缩略图/ 300;

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

你的画廊是否包含很多大图片？在这种情况下，您的Cursor没有问题，但在位图方面有内存管理问题！

此外，您应该在清单中拥有此权限：

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

另见

http://developer.android.com/training/displaying-bitmaps/load-bitmap.html

Answer 2

将此添加到您的清单

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

至于内存不足，当我的图像尺寸非常大时，我会尝试这样做用小图片测试它..

Answer 3

我对所有人的建议，请尝试不要使用大图片尺寸使用https://tinypng.com/来缩小图像尺寸

第二次将应用程序标记中的mainfest android:largeHeap="true"的堆大小增加到此类

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

并捆绑最大堆大小

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.0'

   .......
   ....

    dexOptions {
        javaMaxHeapSize "4g"

    }
}

我希望这个帮助

Answer 4

添加

 android:largeHeap="true"

在您的Manifest应用程序代码中。
