获取图像I创建访问库中的代码，请选择一个图像，裁剪图像，之后，代码调用保存文件的功能，这个功能给，EA错误：错误从画廊
at com.alexandreccarmo.beerin.user.activities.UserPerfilActivity.onSelectFromGalleryResult(UserPerfilActivity.java:396) at com.alexandreccarmo.beerin.user.activities.UserPerfilActivity.onActivityResult(UserPerfilActivity.java:238)
该错误是指这条线：
BM = MediaStore.Images.Media.getBitmap（getApplicationContext（）getContentResolver（），data.getData（））;
这是函数：
private void onSelectFromGalleryResult(Intent data) throws IOException {
Bitmap bm=null;
if (data != null) {
bm = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), data.getData());
Bitmap thumbnail = bm;
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
//File destination = new File(Environment.getExternalStorageDirectory(),System.currentTimeMillis() + ".jpg");
File destination = new File(Environment.getExternalStorageDirectory(), "image.jpg");
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
ivImage.setImageBitmap(bm);
dialog = ProgressDialog.show(UserPerfilActivity.this, "", "Alterando a foto...", true);
}
我怎样才能解决这个问题？
这是完整的代码：
private void galleryIntent()
{
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);//
//crop
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", 96);
intent.putExtra("outputY", 96);
// retrieve data on return
intent.putExtra("return-data", true);
startActivityForResult(Intent.createChooser(intent, "Select File"), SELECT_FILE);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
imagePath = this.destinationUpload.getAbsolutePath();
if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_FILE)
try {
onSelectFromGalleryResult(data);
} catch (IOException e) {
e.printStackTrace();
}
}
}

Android [没有'CROP'' Intent']（https://commonsware.com/blog/2013/01/23/no-android-does-not-have-crop-intent.html）。有很多[可用于Android的图像裁剪库]（https://android-arsenal.com/tag/45）。请使用其中一种，而不是假设这些附加功能适用于所有设备。除此之外，请编辑您的问题并发布整个堆栈跟踪。 – CommonsWare
对不起，我不使用“com.android.camera.action.CROP”。它只是一个考验。但错误是一样的。我编辑了我的帖子。 –
