This article mainly introduces how to use Android to integrate Tencent X5 to achieve document browsing function, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to know it.

Download Tencent X5 kernel

1. Go to https://x5.tencent.com/ to download the kernel of Android. The new version of Tencent X5 can integrate api 'com.tencent.tbs.tbssdk:sdk:43697', directly into bulid.gradle. If you integrate it in App, you can replace api with implementation.

Import 2.AndroidStudio into Tencent X5

a. Import the downloaded jar package into libs, then run as, and then import jnilibs into main package.

B. Module build.gradle add cpu adaptation

Initialize Tencent X5 in 3.Application and call the init method in the onCreate () method

QbSdk.initX5Environment (this, new QbSdk.PreInitCallback () {@ Override public void onCoreInitFinished () {} @ Override public void onViewInitFinished (boolean b) {Log.e ("xxx", "hasLoad" + b); / / the state of successful kernel loading is saved locally, and the SharePreference utility class can be replaced with its own SharedPreferenceUtils.saveBoolean (getApplicationContext (), "hasLoad", b);}})

4. Calls within the application, regardless of whether the kernel is loaded or not, download the online documents locally and open them. The difference is that the unloaded kernel will use QQ Browser or other App's file browsing function similar to Wechat (this call is automatically handled by Tencent X5, so we don't need to care), while after loading the kernel, use X5's TbsReaderView to open the file, followed by the specific code.

Integration of Retrofit,RxJava and progress manager ProgressManager in a.bulid.gradle

Implementation 'io.reactivex:rxandroid:1.2.1' implementation' com.squareup.retrofit2:converter-gson:2.3.0' implementation 'com.squareup.retrofit2:adapter-rxjava:2.1.0' implementation' com.squareup.retrofit2:retrofit:2.3.0' implementation 'io.reactivex:rxjava:1.2.6' implementation' me.jessyan:progressmanager:1.5.0'

Write network download tool

Public interface LoadFileApi {@ GET Call loadPdfFile (@ Url String fileUrl);} public class LoadFileModel {/ / use this method to download the file public static void loadPdfFile (String url, Callback callback) {Retrofit retrofit = new Retrofit.Builder () .baseUrl ("https://www.baidu.com/") .client (ProgressManager.getInstance (). With (new OkHttpClient.Builder ()) .build ()) .addConverterFactory (GsonConverterFactory.create ()) .build (); LoadFileApi mLoadFileApi = retrofit.create (LoadFileApi.class) If (! TextUtils.isEmpty (url)) {Call call = mLoadFileApi.loadPdfFile (url); call.enqueue (callback);}

b. Specific call

First of all, register file progress download monitoring

Private ProgressDialog commonProgressDialog;// switches to its own progress control private ProgressInfo mLastDownloadingInfo; ProgressManager.getInstance () .addResponseListener (url, new ProgressListener () {@ Override public void onProgress (ProgressInfo progressInfo) {if (mLastDownloadingInfo = = null) {mLastDownloadingInfo = progressInfo;} / / because it takes the time at the start of the request as Id, so the higher the value, the newer the if (progressInfo.getId ()

MLastDownloadingInfo.getId () {mLastDownloadingInfo = progressInfo;} int progress = mLastDownloadingInfo.getPercent (); commonProgressDialog.setProgress (progress); Log.d ("xxx", "- Download--" + progress + "%" + mLastDownloadingInfo.getSpeed () + "byte/s" + mLastDownloadingInfo.toString ()); if (mLastDownloadingInfo.isFinish ()) {/ / description that commonProgressDialog.dismiss () has been downloaded; Log.d ("xxx", "--Download-- finish") } @ Override public void onError (long id, Exception e) {e.printStackTrace (); new Handler () .post (new Runnable () {@ Override public void run () {commonProgressDialog.dismiss ();}});}});});}

Then open the file.

Private static final String DOWN_DIR = Environment.getExternalStorageDirectory () + File.separator+ "Download"; / / the path to download the file, you can customize / / open the file private void openFile (String filePath,String fileName) {boolean hasLoad = SharedPreferenceUtils.getBoolean (mContext, "hasLoad"); / / whether to record the kernel if (hasLoad) {/ / Activity Intent intentDoc = new Intent (this,FileDisplayActivity.class); intentDoc.putExtra ("path", filePath); intentDoc.putExtra ("fileName", fileName); startActivity (intentDoc) } else {if (! Environment.getExternalStorageState (). Equals (Environment.MEDIA_MOUNTED)) {Toast.makeText (this, "current SD unavailable", Toast.LENGTH_LONG). Show (); return;} try {File file = new File (DOWN_DIR, fileName); if (file.exists ()) {QbSdk.openFileReader (this, file.getAbsolutePath (), null, new ValueCallback () {@ Override public void onReceiveValue (String s) {Log.e ("xxx", s);}}) } else {downLoadFile (filePath,fileName);}} catch (Exception e) {e.printStackTrace (); ToastUtils.showShortToast (mContext, "already downloaded");} private void downLoadFile (final String url, final String fileName) {commonProgressDialog.show (); LoadFileModel.loadPdfFile (url, new Callback () {@ Override public void onResponse (@ NonNull Call call, @ NonNull Response response) {InputStream is = null; byte [] buf = new byte [2048]; int len; FileOutputStream fos = null Try {ResponseBody responseBody = response.body (); if (responseBody! = null) {is = responseBody.byteStream (); final File file = new File (DOWN_DIR, fileName); fos = new FileOutputStream (file); while ((len = is.read (buf)! =-1) {fos.write (buf, 0, len);} fos.flush () / / unloaded kernel calling methods QbSdk.openFileReader (mContext, file.getAbsolutePath (), null, new ValueCallback () {@ Override public void onReceiveValue (String s) {Log.e ("xxx", s);}}); ToastUtils.showLongToast (MeetingDetailActivity.this, "downloaded successfully, saved in Download folder");}} catch (Exception e) {commonProgressDialog.dismiss (); ProgressManager.getInstance () .notifyOnErorr (url,e) ToastUtils.showLongToast (MeetingDetailActivity.this, "download failed");} finally {try {if (is! = null) is.close ();} catch (IOException e) {e.printStackTrace ();} try {if (fos! = null) fos.close ();} catch (IOException e) {e.printStackTrace ();} @ Override public void onFailure (@ NonNull Call call, @ NonNull Throwable t) {t.printStackTrace (); ToastUtils.showShortToast (MeetingDetailActivity.this, "download failed") CommonProgressDialog.dismiss ();});}

FileDisplayActivity code, for some package names, you can switch to your own package name, and some third-party libraries like progress display, or you can switch to your own progress control.
