Ii. Access sharing

1. Apply for AppID

If you do not have AppID, you can download the official Demo and use AppID in the Demo.

SDK and Demo: https://open.weixin.qq.com/cgi-bin/frame? T = resource/res_main_tmpl & verify = 1 & lang = zh_CN & target = res/app_download_android

Development Kit (SDK)

Use the libraries and files required for sharing, login, favorites, and payment. Click to download the Android Development Kit

Use the speech recognition interface and speech synthesis interface. Click to download the audio SDK + Demo + development document

Use the image recognition interface. Click to download image SDK + Demo + development document

Use the coupon function interface. Click to download the coupon SDK + development document

Sample Code

Contains a complete sample project. For more information about how to use this example, see HelloWeixin @ Android. Click to download

Signature generation tool

Obtains the apk package signed by a third-party app installed on the mobile phone. Click to download the signature generation tool

After the download is complete, we can refer to the Demo for integration.

2. Download The Development Kit (downloaded above)

3. Create a development environment and copy the libammsdk. jar file to the lib directory of the project.

Note: If you use AppID in the Demo, the package name must be the same as the package name in the Demo. Otherwise, an error occurs during sharing.

4. Create an Activity and place a button in it.

package net.sourceforge.simcpux;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import com.example.weixinsharedemo.share.WeixinShareManager;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Button button = (Button) findViewById(R.id.share_weibo);button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {WeixinShareManager wsm = WeixinShareManager.getInstance(MainActivity.this);wsm.shareByWeixin(wsm.new ShareContentPic(R.drawable.ic_launcher),WeixinShareManager.WEIXIN_SHARE_TYPE_TALK);}});}}

<RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android" xmlns: tools = "http://schemas.android.com/tools" android: layout_width = "match_parent" android: layout_height = "match_parent" android: paddingBottom = "@ dimen/activity_vertical_margin" android: paddingLeft = "@ dimen/plugin" android: paddingRight = "@ dimen/plugin" android: paddingTop = "@ dimen/plugin" tools: context = ". mainActivity "> <Button android: id =" @ + id/pai_weibo "android: layout_width =" wrap_content "android: layout_height =" wrap_content "android: text = "share to"/> </RelativeLayout>

4. Start to create our sharing logic class and implement the required sharing function.

Package com. example. weixinsharedemo. share; import android. content. context; import android. graphics. bitmap; import android. graphics. bitmapFactory; import android. widget. toast; import com. example. weixinsharedemo. util. weixiShareUtil; import com. tencent. mm. sdk. modelmsg. sendMessageToWX; import com. tencent. mm. sdk. modelmsg.

You can choose to send the message to the WXSceneSession session or the WXSceneTimeline in the circle of friends. Sent to the session by default. Req. scene = shareType; wxApi. sendReq (req);}/** share image */private void sharePicture (int shareType, ShareContent shareContent) {Bitmap bmp = BitmapFactory. decodeResource (context. getResources (), response content. getPicResource (); WXImageObject imgObj = new WXImageObject (bmp); WXMediaMessage msg = new WXMediaMessage (); msg. mediaObject = imgObj; Bitmap thumbBmp = Bitmap. createScaledBitmap (bmp, THUMB_SIZE, THUMB_S IZE, true); bmp. recycle (); msg. thumbData = WeixiShareUtil.bmp ToByteArray (thumbBmp, true); // set the thumbnail SendMessageToWX. req req = new SendMessageToWX. req (); req. transaction = buildTransaction ("img1_appdata"); req. message = msg; req. scene = shareType; wxApi. sendReq (req);}/** sharing link */private void publish webpage (int shareType, ShareContent publish content) {WXWebpageObject webpage = new WXWebpageObject (); webpage. we BpageUrl = Invalid Content. getURL (); WXMediaMessage msg = new WXMediaMessage (webpage); msg. title = Invalid Content. getTitle (); msg. description = Invalid Content. getContent (); Bitmap thumb = BitmapFactory. decodeResource (context. getResources (), response content. getPicResource (); if (thumb = null) {Toast. makeText (context, "the image cannot be blank", Toast. LENGTH_SHORT ). show ();} else {msg. thumbData = WeixiShareUtil.bmp ToByteArray (thumb, t Rue);} SendMessageToWX. req req = new SendMessageToWX. req (); req. transaction = buildTransaction ("webpage"); req. message = msg; req. scene = shareType; wxApi. sendReq (req);} private String buildTransaction (final String type) {return (type = null )? String. valueOf (System. currentTimeMillis (): type + System. currentTimeMillis ();}}

Only text, images, and links can be shared. You can add videos and audios if you want to share them.

5. Implement feedback on shared results

To implement feedback on shared results, we have encapsulated the results into WXEntryActivity (in the jar package). Therefore, we need to inherit this class to obtain feedback results.

Create a wxapi directory under the corresponding directory of your package name, and add a WXEntryActivity class under the wxapi directory. This class inherits from Activity (for example, the package name of the application is net. sourceforge. simcpux, the newly added class is shown in)

package net.sourceforge.simcpux.wxapi;import com.example.weixinsharedemo.share.WXCallbackActivity;public class CallBackActivity extends WXCallbackActivity{@Overridepublic void weixinResp(int respCode) {System.out.println("respCode = " + respCode);}}

Note: Remember to register the Activity in the Mainfest file.

<? Xml version = "1.0" encoding = "UTF-8"?> <Manifest xmlns: android = "http://schemas.android.com/apk/res/android" package = "net. sourceforge. simcpux "android: versionCode =" 1 "android: versionName =" 1.0 "> <uses-sdk android: minSdkVersion =" 8 "android: targetSdkVersion = "18"/> <uses-permission android: name = "android. permission. INTERNET "/> <uses-permission android: name =" android. permission. WRITE_EXTERNAL_STORAGE "/> <application android: allowBackup =" true "android: icon =" @ drawable/ic_launcher "android: label =" @ string/app_name "android: theme = "@ style/AppTheme"> <activity android: name = "net. sourceforge. simcpux. mainActivity "android: label =" @ string/app_name "> <intent-filter> <action android: name =" android. intent. action. MAIN "/> <category android: name =" android. intent. category. LAUNCHER "/> </intent-filter> </activity> <activity android: name =" net. sourceforge. simcpux. wxapi. callBackActivity "android: label =" @ string/app_name "android: exported =" true "> </activity> <meta-data android: name =" WEIXIN_APP_ID "android: value = "Your AppId"/> </application> </manifest>

3. If you are running the code using AppId in the Demo, please set the signature file (which is included in the SDK downloaded above) as follows:

Click Browser to select and run.

If you have any questions, please leave a message below. You can also add the QQ group (142979499) next to your blog for detailed communication. In addition, let's take a look at my sunshine stack (www.sunhome.aliapp.com ).

Q: How can I share my notes on Android notepad, Weibo, and other social software?

Intent intent = new Intent (Intent. ACTION_SEND );

Intent. setType ("text/plain ");
Intent. putExtra (Intent. EXTRA_STREAM, u );
Intent. putExtra (Intent. EXTRA_SUBJECT, "share ");
Intent. putExtra (Intent. EXTRA_TEXT, "shared content ");
Intent. setFlags (Intent. FLAG_ACTIVITY_NEW_TASK );
This. startActivity (Intent. createChooser (intent, "share "));

The android development process can be shared. The Demo is similar to the sharing on the Internet,
