这是我的相机意图。
File file = getExternalFilesDir(Environment.DIRECTORY_DCIM);
file.mkdirs();
File output = new File(file, "profile_image");
if (output.exists()) {
output.delete();
}
Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, output);
startActivityForResult(captureIntent, PublicValues.IMAGE_FROM_CAMERA);
in onActivityresult
if (requestCode == PublicValues.IMAGE_FROM_CAMERA) {
if (mPhotoUri != null) {
performCrop(mPhotoUri);
} else {
pictureUri = data.getData();
performCrop(pictureUri);
}
和作物意图
Intent cropIntent = new Intent("com.android.camera.action.CROP");
cropIntent.setDataAndType(picUri, "image/*");
cropIntent.putExtra("crop", "true"); // set crop properties
cropIntent.putExtra("aspectX", 1); // indicate aspect of desired crop(ratio)
cropIntent.putExtra("aspectY", 1);
cropIntent.putExtra("return-data", true); // retrieve data on return
cropIntent.putExtra("outputX", profileImage.getWidth()); // indicate output X and Y
cropIntent.putExtra("outputY", profileImage.getHeight());
startActivityForResult(cropIntent, PublicValues.IMAGE_CROP);
它适用于API 19设备,但在Marshmallow设备中崩溃。
崩溃报告是这样的: -
Caused by android.os.FileUriExposedException: file:///storage/emulated/0/WhatsApp/Media/WhatsApp Images/IMG-20170721-WA0014.jpg exposed beyond app through Intent.getData()

答案 0 :(得分:3)
使用Gradle:
compile 'com.theartofdev.edmodo:android-image-cropper:2.3.+'
试试这个:
private void performCrop(Uri imageUri) {
CropImage.activity(imageUri)
.setGuidelines(CropImageView.Guidelines.ON)
.setCropShape(CropImageView.CropShape.RECTANGLE)
.setAspectRatio(1, 1)
.setMultiTouchEnabled(true)
.start(this);
}
