根因分析

应用尝试将大位图（例如，来自相机或网络）加载到内存而不进行缩放，超过了每个应用的堆限制。

English

App tries to load a large bitmap (e.g., from camera or network) into memory without downscaling, exceeding the per-app heap limit.

解决方案

  1. Use BitmapFactory.Options to downsample the image: BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 4; // reduces size by factor of 4 Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.large_image, options);
  2. Use an image loading library like Glide or Coil that handles downsampling and caching automatically: Glide.with(context).load(url).override(800, 600).into(imageView);
  3. If loading from camera, use getBitmap() with a reduced max dimension: Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length, options); where options.inJustDecodeBounds = true is used first to calculate the sample size.

无效尝试

常见但无效的做法:

  1. 80% 失败

    Increasing the heap size via android:largeHeap="true" in the manifest is not a reliable fix because the system may still kill the app, and it only provides a larger limit, not unlimited memory.

  2. 90% 失败

    Using BitmapFactory.decodeResource() without any options loads the full-resolution bitmap, which will still cause OOM for large images.

  3. 85% 失败

    Calling System.gc() before loading an image does not guarantee that enough memory will be freed, and the garbage collector may not run immediately.
