android项目接入Tbs-实现项目内部打开office在线文档并解决.so文件加载不上的问题

1、去官网下载jar包，网址：https://x5.tencent.com/tbs/sdk.html

2、将jar包复制在项目libs下，并右键add libra…，新建JniLibs文件，将事例中的armeabi文件复制进去，如下图：

3、在module的build.gradle添加：

   defaultConfig {
   ......
        ndk {
            // 声明创建so库的文件名,会自动添加lib前缀, 添加了前缀,不会自动添加
             moduleName "MathKit"    //声明启用Android日志, 在c/c++的源文件中使用的#include <android/log.h> 日志将得到输出
             ldLibs "log"
            //选择要添加的对应 cpu 类型的 .so 库。
            abiFilters 'armeabi', 'armeabi-v7a', 'x86'
        }
        repositories {

            maven {url 'http://repo1.maven.org/maven2' }

        }
    }

4、在manifest加权限：

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

5、在项目Application文件里加载x5内核，本地安装qq或微信的可加载成功。

  //搜集本地tbs内核信息并上报服务器，服务器返回结果决定使用哪个内核。
        QbSdk.initX5Environment(this, new QbSdk.PreInitCallback() {

            @Override
            public void onCoreInitFinished() {
                //x5内核初始化完成回调接口，此接口回调并表示已经加载起来了x5，有可能特殊情况下x5内核加载失败，切换到系统内核。
            }

            @Override
            public void onViewInitFinished(boolean b) {
                //x5內核初始化完成的回调，为true表示x5内核加载成功，否则表示x5内核加载失败，会自动切换到系统内核。
                Log.e("@@","加载内核是否成功:" + b);//打印出来可排错
                initX5 = b;
            }
        });

6、配置完成后使用：

import com.tencent.smtt.sdk.TbsReaderView;

import java.io.File;
/**
 * Created by rjj on 2018/12/14
 */
public class OfficePlayerActivity implements TbsReaderView.ReaderCallback,View.OnClickListener {

    //读写权限
    private static String[] PERMISSIONS_STORAGE = {
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.WRITE_EXTERNAL_STORAGE};
    //请求状态码
    private static int REQUEST_PERMISSION_CODE = 1;
    private Button mDownloadBtn;

    @Override
    protected int getLayoutId() {
        return R.layout.activity_office_player;
    }

    @Override

        rootRl.addView(mTbsReaderView, new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));

        **//动态添加文件的读写权限，6.0以上需要动态添加读写权限**
        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP) {
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions(this, PERMISSIONS_STORAGE, REQUEST_PERMISSION_CODE);
            }else{
                setData();
            }

        String path1 = getLocalFile().getPath() + mFileName;
        //显示文件
        Bundle bundle = new Bundle();
        bundle.putString("filePath", new File(getLocalFile().getPath()).toString());
        bundle.putString("tempPath", Environment.getExternalStorageDirectory() + "/" + path);
//        bundle.putString("filePath", "/storage/emulated/0/Download/"+path+mFileName);

        boolean result = mTbsReaderView.preOpen(getFileType(new File(path1).toString()), false);
        if (result) {

    private String parseFormat(String fileName) {

    }

    private void startDownload() {
        mDownloadObserver = new DownloadObserver(new Handler());
        getContentResolver().registerContentObserver(Uri.parse("content://downloads/my_downloads"), true, mDownloadObserver);
        mDownloadManager = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
        DownloadManager.Request request = new DownloadManager.Request(Uri.parse(mFileUrl));

                //状态所在的列索引
                int status = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_STATUS));
                Log.i("downloadUpdate: ", currentBytes + " " + totalBytes + " " + status);

        } finally {
            if (cursor != null) {
                cursor.close();
            }

    }

    @Override
    public void onCallBackAction(Integer integer, Object o, Object o1) {

    }

    @Override

        }
    }

    @Override

        switch (v.getId()){
            case R.id.left_bar_ll:
                finish();
                break;
        }
    }
    private class DownloadObserver extends ContentObserver {

        private DownloadObserver(Handler handler) {
            super(handler);
        }

        @Override
        public void onChange(boolean selfChange, Uri uri) {
            Log.i("downloadUpdate: ", "onChange(boolean selfChange, Uri uri)");
            queryDownloadStatus();
        }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == REQUEST_PERMISSION_CODE) {
            setData();//执行文件下载或打开方法
            for (int i = 0; i < permissions.length; i++) {
                Log.i("MainActivity", "申请的权限为：" + permissions[i] + ",申请结果：" + grantResults[i]);
            }
        }
    }
}

7、如果armeabi文件下的.so加载不上（在你的项目里用到多个第三方库时会出现这类问题），可以在project的.gradle里面添加：

// 保证dex_files文件中指定的文件都加载到Main Dex中
afterEvaluate {
    tasks.matching {
        it.name.startsWith('dex')
    }.each { dx ->
        if (dx.additionalParameters == null) {
            dx.additionalParameters = []
        }
        dx.additionalParameters += '--multi-dex'
        dx.additionalParameters += "--main-dex-list=$projectDir/dex_files".toString()
    }
}

8、混淆打包在proguard-rules.pro文件里添加：
