我按照这个旋转捕获的图像。但我有一个错误。

LogCat错误

这是236号线
Bitmap rotatedBitmap = Bitmap.createBitmap(bm, 0, 0, bitmapOptions.outWidth, bitmapOptions.outHeight, matrix, true);
我怎样才能解决这个问题？我从中找到了很多解决方案，但我仍然不知道如何解决它。有人能帮我解决这个问题吗？任何帮助都会很好，谢谢！！

cameraAndGalaryPicture（）这是用于打开相机捕获方法的方法。countFix此变量用于其Fix 6。parseFileCamera这是Parse数组。这是解析文件对象
我在解析数据库时使用它。此外，u将采取字节数组或其他明智的位图数组来存储更多的图像。

我猜你的应用程序是内存密集型的，你的相机图片至少应该有1280x720的大小。我修改了你的代码创建了一个名为
解码位图
private Bitmap decodeBitmap(String filePath, int reqWidth, int reqHeight, int scale) throws IOException, Exception {
if (scale > 3)
throw new Exception("scale size cannot be greater than 3");
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inJustDecodeBounds = true;
BitmapFactory.decodeFile(filePath, bmOptions);
int photoW = bmOptions.outWidth;
int photoH = bmOptions.outHeight;
// Determine how much to scale down the image
bmOptions.inSampleSize = scale + Math.min(photoW / reqWidth, photoH / reqHeight);
bmOptions.inJustDecodeBounds = false;
try {
Bitmap bm = BitmapFactory.decodeFile(filePath, bmOptions);
ExifInterface exif = new ExifInterface(filePath);
String orientString = exif.getAttribute(ExifInterface.TAG_ORIENTATION);
int orientation = orientString != null ? Integer.parseInt(orientString) : ExifInterface.ORIENTATION_NORMAL;
int rotationAngle = 0;
if (orientation == ExifInterface.ORIENTATION_ROTATE_90) rotationAngle = 90;
if (orientation == ExifInterface.ORIENTATION_ROTATE_180) rotationAngle = 180;
if (orientation == ExifInterface.ORIENTATION_ROTATE_270) rotationAngle = 270;
Matrix matrix = new Matrix();
matrix.setRotate(rotationAngle, (float) bm.getWidth() / 2, (float) bm.getHeight() / 2);
return Bitmap.createBitmap(bm, 0, 0, photoW, photoH, matrix, true);
} catch (OutOfMemoryError exception) {
exception.printStackTrace();
return decodeBitmap(filePath, reqWidth, reqHeight, scale + 1);
}
}
onActivityResult
try {
mImageView.setImageBitmap(decodeBitmap(mCurrentPhotoPath,1024,1024,0));
} catch (Exception e) {
e.printStackTrace();
}
让我警告你，这个功能的工作原理是降低一些图像质量。希望它能帮助你。。。

你应该让更少的位图进入内存不正确。在文件系统中存储<代码>回收位图当您永远不需要它们时<代码>设置图像位图位图后，只需使用glide或Universal Image Loader加载它。
