Android 7.0+相机、相册、裁剪适配问题
在manifest中：
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.***.***.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
1、android:authorities：可以随便取，在之后的代码需要一一对应：
2、android:resource：创建一个xml文件夹，xml文件夹下创建file_paths资源文件
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<paths>
<external-path path="" name="camera_photos" />
<files-path path="" name="photos" />
</paths>
</resources >
代码中：
private String mPhotoPath;
private Bitmap mBitmap;
private File mAvatarFile;
private File fileUri;
/**
* 调用手机相机
*/
private void getImageFromPhoto() {
File file = new File(Constants.APP_PATH);
if (!file.exists()) {
file.mkdirs();
}
mPhotoPath = Constants.APP_PATH + String.valueOf(System.currentTimeMillis()) + ".jpg";
fileUri = new File(mPhotoPath);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
imageUri = FileProvider.getUriForFile(ChangeUserInfoActivity.this, "com.***.***.fileprovider", fileUri);
} else {
imageUri = Uri.fromFile(fileUri);
}
intentCamera.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
intentCamera.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intentCamera, START_PHOTO_CAMERA_REQUEST);
}
/**

private void allPhoto() {

//游标移到第一位，即从第一位开始读取
if (cursor != null) {
cursor.moveToFirst();
mPhotoPath = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
cursor.close();
//调用系统裁剪
mAvatarFile = new File(mPhotoPath);
final Uri uri;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
uri = FileProvider.getUriForFile(this, "com.***.***.fileprovider", mAvatarFile);
} else {

}

}
} if (requestCode == START_PHOTO_CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
//相机返回结果，调用系统裁剪
mAvatarFile = new File(mPhotoPath);
Uri uri;

} else {

}

}
}
}
/**
