I am trying to implement the mupdf library to render pdf documents in my app.My app crashes with the following error log:-

这是我要实现的示例代码.

This is the sample code that I am trying to implement.

package com.inevitablesol.www.demopdf;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.RelativeLayout;

import com.artifex.mupdfdemo.FilePicker;
import com.artifex.mupdfdemo.MuPDFCore;
import com.artifex.mupdfdemo.MuPDFPageAdapter;
import com.artifex.mupdfdemo.MuPDFReaderView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RelativeLayout layout = (RelativeLayout) findViewById(R.id.main_layout);

        MuPDFCore core = null;
        try {
            core = new MuPDFCore(this,"/storage/emulated/0/sample.pdf");
        } catch (Exception e) {
            e.printStackTrace();
        }
        MuPDFReaderView reader = new MuPDFReaderView(this);
        reader.setAdapter(new MuPDFPageAdapter(this, new FilePicker.FilePickerSupport() {
            @Override
            public void performPickFor(FilePicker filePicker) {

            }
        },core));

        layout.addView(reader);
    }
}

推荐答案

在/app/src/main/位置创建jniLibs文件夹. 然后在jnoLibs文件夹中创建armeabi，armeabi-v7a文件夹，然后在该文件夹中添加libmupdf.so文件.

Create jniLibs folder at this location /app/src/main/. And in jnoLibs folder create armeabi, armeabi-v7a folder and add libmupdf.so file in that folders.
