我在图库中选择“BIG SIZE图像并捕获图像高质量”然后强制关闭错误另见代码和错误...谢谢
代码:

selectedImagePath = getPath(selectedImageUri);
user_img.setImageURI(selectedImageUri);
Log.e("select image from gallary ", "" + selectedImagePath);
} else if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
//Uri camrerauri = data.getData();
selectedImagePath = getPath(selectedImageUri);
user_img.setImageURI(selectedImageUri);
Log.e("capture image ", "" + selectedImagePath);
}
}
}

看起来你内存不足。 我通过在处理之前将图像写入sd解决了这个问题。我现在不能发送代码但稍后。实际处理图像需要大量内存。因此,您应该在处理图像之前考虑调整位图大小。
提示: 您可能无法写入位图。您必须复制该位图,以便访问和编辑像素。
这就是为什么我必须将位图的副本复制到我的sd,因为将副本写入内存会导致异常。
试试这个:
编辑: 你去... 如何从相机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Bitmap转换为可变位图,这样你就可以编辑像素(我想我从pastebin那里得到了这个,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;
}
