我在图库中选择“大尺寸图像并捕获高质量图像”然后强制关闭错误另请参阅以下代码和错误...谢谢

代码：

看起来你的内存用完了。我通过在处理之前将图像写入 sd 解决了这个问题。我现在无法将代码发送给您，但稍后再发送。Acutally 处理图像会占用大量内存。因此，您应该在处理图像之前考虑调整位图的大小。

提示：您可能无法写入位图。您必须制作该位图的副本，以便您可以访问和编辑像素。

这就是为什么我必须将位图副本复制到我的 sd，因为将副本写入内存会导致异常。

尝试这个：

  • 加载图像
  • 将副本写入 sd
  • 冲洗
  • 加载副本并尝试处理

编辑：给你...如何从相机中获取大图像并处理位图：

rivate void openCamera() {
    String _path = Environment.getExternalStorageDirectory()
            + File.separator + "temp.JPEG";
    tempFile = new File(_path);
    outputFileUri = Uri.fromFile(tempFile);
    bitmap = null;
    // start default camera
    Intent cameraIntent = new Intent(
            android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,
            outputFileUri);
    startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}


private void process() {
    Bitmap editableBitmap = processor.processImage(bitmap);
    imgView.setImageBitmap(editableBitmap);
    // finish();
}


protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    ready = false;
    if (requestCode == CAMERA_PIC_REQUEST) {
        // bitmap = BitmapFactory.decodeFile(_path);
        try {
            bitmap = MediaStore.Images.Media.getBitmap(
                    getApplicationContext().getContentResolver(),
                    outputFileUri);
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        if (imgView == null) {
            imgView = (ImageView) findViewById(R.id.imageView1);
        }
        process();
    }
}

将位图转换为可变位图，以便您可以编辑像素（我想我是从 pastebin 那里得到的，但这并不神奇）

public static Bitmap convertToMutable(Bitmap imgIn) {
        try {
            // this is the file going to use temporally to save the bytes.
            // This file will not be a image, it will store the raw image data.
            File file = new File(Environment.getExternalStorageDirectory()
                    + File.separator + "temp.tmp");

            // Open an RandomAccessFile
            // Make sure you have added uses-permission
            // android:name="android.permission.WRITE_EXTERNAL_STORAGE"
            // into AndroidManifest.xml file
            RandomAccessFile randomAccessFile = new RandomAccessFile(file, "rw");

            // get the width and height of the source bitmap.
            int width = imgIn.getWidth();
            int height = imgIn.getHeight();
            Config type = imgIn.getConfig();

            // Copy the byte to the file
            // Assume source bitmap loaded using options.inPreferredConfig =
            // Config.ARGB_8888;
            FileChannel channel = randomAccessFile.getChannel();
            MappedByteBuffer map = channel.map(MapMode.READ_WRITE, 0,
                    imgIn.getRowBytes() * height);
            imgIn.copyPixelsToBuffer(map);
            // recycle the source bitmap, this will be no longer used.
            imgIn.recycle();
            System.gc();// try to force the bytes from the imgIn to be released

            // Create a new bitmap to load the bitmap again. Probably the memory
            // will be available.
            imgIn = Bitmap.createBitmap(width, height, type);
            map.position(0);
            // load it back from temporary
            imgIn.copyPixelsFromBuffer(map);
            // close the temporary file and channel , then delete that also
            channel.close();
            randomAccessFile.close();

            // delete the temp file
            file.delete();

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return imgIn;
    }
