PhoneGap Andriod 同时安装多个软件.捆绑安装.

现在碰到这么一个需求,在已有App安装时,需要判断另一个app是否安装.以及自动安装.

思路如下,在assets目录下.放另一个apk.文件.

1.采取之前文章说到的,判断某个包名是否安装了.

如果没有安装则跳转到第2步.

2.检测并安装插件制作.

package 你的包名;
 

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;

import org.apache.cordova.api.CallbackContext;
import org.apache.cordova.api.CordovaPlugin;
import org.json.JSONArray;
import org.json.JSONException;

import android.app.AlertDialog;

import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.DialogInterface.OnClickListener;
import android.net.Uri;
import android.os.Environment;
import android.view.Gravity;

import android.widget.Toast;



public class GetApk extends CordovaPlugin {
	
	
	@Override
	public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
		 
		if (action.equals("GetApk")) {
			
			Toast tips;
			 
			
			tips = Toast.makeText(cordova.getActivity(), "", Toast.LENGTH_SHORT);
			tips.setGravity(Gravity.CENTER, 0, 0);

                        //这里的xxxx.apk我是放到assets目录下.
                        //也可以不要这段,直接用下面的下载			 
			
			
			 
			try {
				 if(copyApkFromAssets(cordova.getActivity(), "xxxx.apk", Environment.getExternalStorageDirectory().getAbsolutePath()+"/xxxx.apk"))
				 {  
					 Intent intent = new Intent(Intent.ACTION_VIEW);  
	                 intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
	                 intent.setDataAndType(Uri.parse("file://" + Environment.getExternalStorageDirectory().getAbsolutePath()+"/xxxx.apk"),  
	                                "application/vnd.android.package-archive");  
	                 cordova.getActivity().startActivity(intent); 
				 } 
				 else
				 {
					 
						new AlertDialog.Builder(cordova.getActivity())
								.setTitle("install dhbm")
								.setMessage("Please confirm you want to install dhbm")
								.setPositiveButton("submit",
										new OnClickListener() {
											public void onClick(
													DialogInterface dialog,

												try {

								.setNegativeButton("cancel",
										new OnClickListener() {

											}
										}).show();
				 }
			} 
			catch (Exception e) {
				 
				e.printStackTrace();
			}
			 
            return true;
            
        }
        return false;
    }
	
	public boolean copyApkFromAssets(Context context, String fileName, String path) {  
        boolean copyIsFinish = false;  
       try {  
           InputStream is = context.getAssets().open(fileName);  
           File file = new File(path);  
            file.createNewFile();  
            FileOutputStream fos = new FileOutputStream(file);  
           byte[] temp = new byte[1024];  
           int i = 0;  
           while ((i = is.read(temp)) > 0) {  
               fos.write(temp, 0, i);  
           }  
           fos.close();  
           is.close();  
            copyIsFinish = true;  
        } catch (IOException e) {  
            e.printStackTrace();  
        }  
        return copyIsFinish;  
   }


}
 

js 部分略过了.之前文章已有讲述.
