[操作系统]调用meitu秀秀.so文件实现美图功能


本文属于实战系列,是对《Android C代码回调java方法》等文的实践,调用meitu秀秀的libmtimage-jni.so文件来实现图片的美化功能

首先反编译得到/libmtimage-jni.so文件和JNI文件

新建项目,将/libmtimage-jni.so文件拷贝到libs文件夹下,新建JNI文件并拷贝代码,并导入loadLibrary

package com.mt.mtxx.image;public class JNI {  static{    System.loadLibrary("mtimage-jni");  }  public native void AutoColor(byte[] paramArrayOfByte, int paramInt1, int paramInt2, int paramInt3, int paramInt4);

项目布局如下:

<RelativeLayout ="http://schemas.android.com/apk/res/android"  ="http://schemas.android.com/tools"  android:layout_width="match_parent"  android:layout_height="match_parent"  android:paddingBottom="@dimen/activity_vertical_margin"  android:paddingLeft="@dimen/activity_horizontal_margin"  android:paddingRight="@dimen/activity_horizontal_margin"  android:paddingTop="@dimen/activity_vertical_margin"  tools:context=".MainActivity" >  <Button    android:id="@+id/button"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:onClick="process"    android:text="美化" />  <ImageView    android:id="@+id/image"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:layout_below="@id/button" /></RelativeLayout>
