Android-the first line of code calls the camera

According to the test, the code in the book does not run properly on its 5.1 version of Huawei's mobile phone. The images that are called are not displayed correctly and appear normal on the company's 4.x version of the phone.

The code is as follows

 Packageorg.quentin.choosepictest;ImportJava.io.File;Importjava.io.FileNotFoundException;Importjava.io.IOException;Importandroid.app.Activity;Importandroid.content.Intent;ImportAndroid.graphics.Bitmap;Importandroid.graphics.BitmapFactory;ImportAndroid.net.Uri;ImportAndroid.os.Bundle;Importandroid.os.Environment;ImportAndroid.provider.MediaStore;ImportAndroid.view.Menu;ImportAndroid.view.MenuItem;ImportAndroid.view.View;ImportAndroid.view.View.OnClickListener;ImportAndroid.widget.Button;ImportAndroid.widget.ImageView;/** After testing, it is no problem to find that the code runs on the company's test machine. But in their own 5.1 mobile phone test results are not normal. * This is really strange. When learning a book, there is still a relatively stable version of the better.

Reasons for the moment are not quite clear, with Log printing and various conditions of debugging, also not normal. At present, familiar with the code phase, temporarily do not drill down, mark a bit, later in-depth study it.
